Most of us have favourite verbs that we default to almost unconsciously when we are writing—reports, argues, describes, studies, explains, asserts—but these verbs are not interchangeable. They each inscribe a slightly different stance towards the knowledge—not only the writer’s stance, but also the stance of the researcher who created the knowledge. It is critical to get the original stance right in your critical summary. Nothing irritates me more than seeing my stance mispresented in someone else’s literature review. For example, if I wrote a paragraph offering tentative reflections on a new idea, I don’t want to see that summarized in someone’s literature review as ‘Lingard argues’, when more accurate would be ‘Lingard suggests’ or ‘Lingard explored’.
Writers need to extend their library of citation verbs to allow themselves to accurately and persuasively position knowledge claims published by authors in their field. You can find many online resources to help extend your vocabulary: Tab. 2 , adapted from one such online source [ 4 ], provides some suggestions. Tables like these should be thought of as tools, not rules—keep in mind that words have flexible meanings depending on context and purpose. This is why one word, such as suggest or conclude , can appear in more than one list.
Verbs to represent the nature and strength of an author’s contributions to the literature
Verbs to report what an author DID | Verbs to report what an author SAID | Verbs to report an author’s OPINION | ||
---|---|---|---|---|
analyse, assess, , discover, describe, demonstrate, examine, explore, establish, find, identify, inquire, prove, observe, study, show | Weaker | Stronger | Weaker | Stronger |
comment, describe, note, remark, add, offer, | affirm, emphasize, stress, maintain, stipulate, explain, , identify, insist | accept, believe, consider, think, , suspect, speculate | argue, assert, claim, contend, deny, recommend, reject, advocate, maintain |
Knowledge is a social construction and it accumulates as researchers debate, extend and refine one another’s contributions. To avoid your literature review reading like a laundry list of disconnected ‘facts’, reporting verbs are an important resource. Tab. 3 offers a selection of verbs organized to reflect different relationships among authors in the field of knowledge being reviewed.
Verbs to express relations among authors in the field
Depicting similar positions | Depicting contrasting positions | Depicting relating/responding positions |
---|---|---|
Taylor Jackson’s claim that … | Taylor Jackson’s claim that … | Taylor to Jackson’s claim that … |
affirms, agrees, confirms, concurs, aligns, shares, echoes, supports, verifies, concedes, accepts | argues, disagrees, questions, dismisses, refuses, rejects, challenges contradicts, criticizes, opposes, counters, disputes | extends, elaborates, refines, builds on, reconsiders, draws upon, advances, repositions, addresses |
Finally, although we have focused on citation verbs in this article, adverbs (e. g., similarly, consequently) and prepositional phrases (e. g., by contrast, in addition) are also important for expressing similar, contrasting or responding relations among knowledge claims and their authors in the field being reviewed.
In summary, an effective literature review not only summarizes existing knowledge, it also critically presents that knowledge to depict an evolving conversation and understanding in a particular domain of study. As writers we need to know when we are summarizing and when we are critically summarizing—summary alone makes for a literature review that reads like a laundry list of undigested ‘facts-in-the-world’. Finally, writers need to attend to the subtle power of citation verbs to position themselves and the authors they are citing in relation to the knowledge being reviewed. Broadening our catalogue of ‘go-to’ verbs is an important step in enlivening and strengthening our writing.

What is a literature review.
A literature review is a summary of the published work in a field of study. This can be a section of a larger paper or article, or can be the focus of an entire paper. Literature reviews show that you have examined the breadth of knowledge and can justify your thesis or research questions. They are also valuable tools for other researchers who need to find a summary of that field of knowledge.
Unlike an annotated bibliography, which is a list of sources with short descriptions, a literature review synthesizes sources into a summary that has a thesis or statement of purpose—stated or implied—at its core.
Step 1: define your research scope.
Ask us if you have questions about refining your topic, search methods, writing tips, or citation management.
Start by searching broadly. Literature for your review will typically be acquired through scholarly books, journal articles, and/or dissertations. Develop an understanding of what is out there, what terms are accurate and helpful, etc., and keep track of all of it with citation management tools . If you need help figuring out key terms and where to search, ask us .
Use citation searching to track how scholars interact with, and build upon, previous research:
Key to your literature review is a critical analysis of the literature collected around your topic. The analysis will explore relationships, major themes, and any critical gaps in the research expressed in the work. Read and summarize each source with an eye toward analyzing authority, currency, coverage, methodology, and relationship to other works. The University of Toronto's Writing Center provides a comprehensive list of questions you can use to analyze your sources.
Divide the available resources that pertain to your research into categories reflecting their roles in addressing your research question. Possible ways to categorize resources include organization by:
Regardless of the division, each category should be accompanied by thorough discussions and explanations of strengths and weaknesses, value to the overall survey, and comparisons with similar sources. You may have enough resources when:
Undergraduate student resources.
A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question. That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.
A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment. Rely heavily on the guidelines your instructor has given you.
Why is it important?
A literature review is important because it:

Your literature review should be guided by your central research question. The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

Tips:
A literature review surveys prior research published in books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have used in researching a particular topic and to demonstrate to your readers how your research fits within existing scholarship about the topic.

A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:
Given this, the purpose of a literature review is to:

Types of Literature Reviews
It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.
In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.
Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.
Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.
Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.
Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.
NOTE: Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

I. Thinking About Your Literature Review
The structure of a literature review should include the following in support of understanding the research problem :
The critical evaluation of each work should consider :
II. Development of the Literature Review
Four Basic Stages of Writing 1. Problem formulation -- which topic or field is being examined and what are its component issues? 2. Literature search -- finding materials relevant to the subject being explored. 3. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4. Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.
Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1. Roughly how many sources would be appropriate to include? 2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4. Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5. Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.
III. Ways to Organize Your Literature Review
Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] A thematic literature review is the most common approach to summarizing prior research in the social and behavioral sciences. Thematic reviews are organized around a topic or issue, rather than the progression of time, although the progression of time may still be incorporated into a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it would still be organized chronologically reflecting technological developments in media. The difference in this example between a "chronological" and a "thematic" approach is what is emphasized the most: themes related to the role of the Internet in presidential politics. Note that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point being made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.
Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.
Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:
IV. Writing Your Literature Review
Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.
Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information, but that are not key to understanding the research problem, can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.
V. Common Mistakes to Avoid
These are the most common mistakes made in reviewing social science research literature.

Break Out of Your Disciplinary Box!
Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.
Frodeman, Robert. The Oxford Handbook of Interdisciplinarity . New York: Oxford University Press, 2010.
Don't Just Review for Content!
While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:
When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.

When Do I Know I Can Stop Looking and Move On?
Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:

4 literature review and citations/references.
Figure 4.1: Literature reviews and references
Your may have done a literature survey as part of your proposal. This will be incorporated into your dissertation, not left as separate stand-alone. Most economics papers include a literature review section, which may be a separate section, or incorporated into the paper’s introduction. (See organising for a standard format.)
Some disambiguation:
A ‘Literature survey’ paper: Some academic papers are called ‘literature surveys’. These try to summarise and discuss the existing work that has been done on a particular topic, and can be very useful. See, for example, works in The Journal of Economic Perspectives, the Journal of Economic Literature, the “Handbook of [XXX] Economics”
Many student projects and undergraduate dissertations are mainly literature surveys.
Your literature review should explain:
what has been done already to address your topic and related questions, putting your work in perspective, and
what techniques others have used, what are their strengths and weaknesses, and how might they be relevant tools for your own analysis.
Figure 4.2: Take notes on this as you read, and write them up.
Focus on literature that is relevant to your topic only.
But do not focus only on articles about your exact topic ! For example, if your paper is about the relative price of cars in the UK, you might cite papers (i) about the global automobile market, (ii) about the theory and evidence on competition in markets with similar features and (iii) using econometric techniques such as “hedonic regression” to estimate “price premia” in other markets and in other countries.
Consider: If you were Colchester a doctor and wanted to know whether a medicine would be effective for your patients, would you only consider medical studies that ran tests on Colchester residents, or would you consider more general national and international investigations?
You should aim to read and cite peer-reviewed articles in reputable economics journals. (Journals in other fields such as Finance, Marketing and Political Science may also be useful.) These papers have a certain credibility as they have been checked by several referees and one or more editors before being published. (In fact, the publication process in Economics is extremely lengthy and difficult.)
Which journals are “reputable”? Economists spend a lot of time thinking about how to rank and compare journals (there are so many papers written about this topic that they someone could start a “Journal of Ranking Economics Journals”. For example, “ REPEC ” has one ranking, and SCIMAGO/SCOPUS has another one. You may want to focus on journals ranked in the top 100 or top 200 of these rankings. If you find it very interesting and relevant paper published somewhere that is ranked below this, is okay to cite it, but you may want to be a bit more skeptical of its findings.
Any journal you find on JSTOR is respectable, and if you look in the back of your textbooks, there will be references to articles in journals, most of which are decent.
You may also find unpublished “working papers”; these may also be useful as references. However, it is more difficult to evaluate the credibility of these, as they have not been through a process of peer review. However, if the author has published well and has a good reputation, it might be more likely that these are worth reading and citing.
You may also find unpublished “working papers” or ‘mimeos’; these may also be useful as references. In fact, the publication process in Economics is so slow (six years from first working paper to publication is not uncommon) that not consulting working papers often means not being current.
However, it is more difficult to evaluate the credibility of this ‘grey literature’, as they have not been through a process of peer review. However, if the author has published well and has a good reputation, it might be more likely that these are worth reading and citing. Some working paper series are vetted, such as NBER; in terms of credibility, these might be seen as something in between a working paper and a publication.

You should be able to find and access all the relevant articles online. Leafing through bound volumes and photocopying should not be neededs. (Having been a student in the late 90’s and 2000’s, I wish I could get those hours back.)
Figure 4.3: The old way!
Good online tools include Jstor (jstor.org) and Google Scholar (scholar.google.co.uk). Your university should have access to Jstor, and Google is accessible to all (although the linked articles may require special access). You will usually have the ‘most access’ when logged into your university or library computing system.If you cannot access a paper, you may want to consult a reference librarian.
It is also ok, if you cannot access the journal article itself, to use the last working paper version (on Google scholar find this in the tab that says “all X versions”, where X is some number, and look for a PDF). However, authors do not always put up the most polished versions, although they should do to promote open-access. As a very last resort, you can e-mail the author and ask him or her to send you the paper.
When looking for references, try to find ones published in respected refereed economics journals (see above ).
A “survey article” is a good place to start; this is a paper that is largely a categorization and discussion of previous work on a particular topic. You can often find such papers in journals such as
These will be useful as a “catalog” of papers to read and considers citing. They are also typically very readable and offer a decent introduction to the issue or the field.
It is also helpful to consult module (course) notes and syllabi from the relevant field. Do not only limit yourself to the ones at your own university; many of universities make their course materials publicly accessible online. These will not only typically contain reading lists with well-respected and useful references, they may also contain slides and other material that will help you better understand your topic and the relevant issues.
However, be careful not to take material from course notes without properly citing it. (Better yet, try to find the original paper that the course notes are referring to.)
Textbooks serve as another extremely useful jumping off point. Look through your own textbooks and other textbooks in the right fields. Textbooks draw from, and cite a range of relevant articles and papers. (You may also want to go back to textbooks when you are finding the articles you are reading too difficult. Textbooks may present a simpler version of the material presented in an article, and explain the concepts better.)
When you find a useful paper, look for its “family.” You may want to go back to earlier, more fundamental references, by looking at the articles that this paper cited. See what is listed as “keywords” (these are usually given at the top of the paper), and “JEL codes”. Check what papers this paper cites, and check what other papers cited this paper. On Google scholar you can follow this with a link “Cited by…” below the listed article. “Related articles” is also a useful link.
Keep track of all references and citations
You may find it helpful to use software to help you manage your citations
A storage “database” of citations (e.g., Jabref, Zotero, Endnote, Mendeley); these interface well with Google Scholar and Jstor
An automatic “insert citation” and “insert bibliography” in your word processing software
Use a tool like Endnote to manage and insert the bibliographies, or use a bibliography manager software such as Zotero or Jabref,
Further discussion: Citation management tools
Put your list of references in alphabetical order by author’s last name (surname).
Include all articles and works that you cite in your paper; do not include any that you don’t cite.
Here is a definition of plagiarism
The main point is that you need to cite everything that is not your own work. Furthermore, be clear to distinguish what is your own work and your own language and what is from somewhere/someone else.
Why cite? Not just to give credit to others but to make it clear that the remaining uncited content is your own.
Here are some basic rules:

Do not submit anything that is not your own work.
Never copy from friends.
Do not copy your own work or previously submitted work. (Caveat: If you are submitting a draft or a ‘literature review and project plan’ at an earlier stage, this can be incorporated into your final submission.
Don’t copy text directly into your work, unless:
It is not sufficient merely to add a citation for the source of copied material following the copied material (typically the end of a paragraph). You must include the copied material in quotation marks. … Ignorance … is no defence.’ (ibid, pp. 15 )
(‘Ibid’ means ‘same as the previous citation’.)
Your university may use sophisticated plagiarism-detection software. Markers may also report if the paper looks suspect
Before final submission, they may ask you to go over your draft and sign that you understand the contents and you have demonstrated that the work is your own.
Not being in touch with your supervisor may put you under suspicion.
Your university may give a Viva Voce oral exam if your work is under suspicion. It is a cool-sounding word but probably something you want to avoid.
Your university may store your work in its our database, and can pursue disciplinary action, even after you have graduated.
Penalties may be severe, including failure with no opportunity to retake the module (course). You may even risk your degree!

True or false: “If you do not directly quote a paper you do not need to cite it” 9
You should read and cite a paper (choose all that are correct)… 10
Use the right terminology.
“Johnson et al. (2000) provide an analytical framework that sheds substantial doubt on that belief. When trying to obtain a correlation between institutional efficiency and wealth per capita, they are left with largely inconclusive results.”
They are not trying to “obtain a correlation”; they are trying to measure the relationship and test hypotheses.
Don’t take everything that is in print (or written online) as gospel truth. Be skeptical and carefully evaluate the arguments and evidence presented. Try to really survey what has been written, to consider the range of opinions and the preponderance of the evidence. You also need to be careful to distinguish between “real research” and propaganda or press releases.
The returns to higher education in Atlantis are extremely high. For the majority of Atlanian students a university degree has increased their lifetime income by over 50%, as reported in the “Benefits of Higher Education” report put out by the Association of Atlantian Universities (2016).
But don’t be harsh without explanation:
Smith (2014) found a return to education in Atlantis exceeding 50%. This result is unlikely to be true because the study was not a very good one.
A theoretical economic model can not really prove anything about the real world; they typically rely on strong simplifying assumptions.
Through their economic model, they prove that as long as elites have incentives to invest in de facto power, through lobbying or corruption for example, they will invest as much as possible in order to gain favourable conditions in the future for their businesses.
In their two period model, which assumes \[details of key assumptions here\] , they find that when an elite Agent has an incentive to invest in de facto power, he invests a strictly positive amount, up to the point where marginal benefit equals marginal cost”
Empirical work does not “prove” anything (nor does it claim to).
It relies on statistical inference under specific assumptions, and an intuitive sense that evidence from one situation is likely to apply to other situations.
“As Smith et al (1999) proved using data from the 1910-1920 Scandanavian stock exchange, equity prices always increase in response to reductions in corporate tax rates.”
“Smith et al (199) estimated a VAR regression for a dynamic CAP model using data from the 1910-1920 Scandanavian stock exchange. They found a strongly statistically significant negative coefficient on corporate tax rates. This suggests that such taxes may have a negative effect on publicly traded securities. However, as their data was from a limited period with several simultaneous changes in policy, and their results are not robust to \[something here\] , further evidence is needed on this question.”
Use the language of classical 11 statistics:
Hypothesis testing, statistical significance, robustness checks, magnitudes of effects, confidence intervals.
Note that generalisation outside the data depends on an intuitive sense that evidence from one situation is likely to apply to other situations.
This policy was explained by Smith and Johnson (2002) in their research on subsidies and redistribution in higher education. Their results showed that people with higher degree have higher salaries and so pay higher taxes. Thus subsidizing higher education leads to a large social gain.
The results the student discusses seem to show an association between higher degrees and higher salaries. The student seems to imply that the education itself led to higher salaries. This has not been shown by the cited paper. Perhaps people who were able to get into higher education would earn higher salaries anyway. There are ways economists used to try to identify a “causal effect” (by the way, this widely used term is redundant as all effects must have a cause), but a mere association between two variables is not enough
As inflation was systematically lower during periods of recession, we see that too low a level of inflation increases unemployment.
Economists have long debated the nature of this “Phillips curve” relationship. There is much work trying to determine whether the association (to the extent it exists) is a causal one. We could not rule out reverse causality, or third factor that might cause changes in both variables.
Don’t write: “I accept the null hypothesis.”
Do write: “The results fail to reject the null hypothesis, in spite of a large sample size and an estimate with small standard errors” (if this is the case)
Note: The question of what to infer from acceptance/rejection of null hypotheses is a complex difficult one in Classical (as opposed to Bayesian) statistics. This difficulty is in part philosophical: classical hypothesis testing is deductive , while inference is necessarily inductive.
You need to read this paper more clearly; it is not clear what they conclude nor what their evidence is.
A common marking comment:
These papers seem to be discussed in random order – you need some structure organising these papers thematically, by finding, by technique, or chronologically perhaps.
How should you organise it? In what order?
Thematically (usually better)
By method, by theoretical framework, by results or assumptions, by field
Chronologically (perhaps within themes)
Exercise: Compare how the literature review section is organized in papers you are reading.
Figure 4.4: Organising a set of references
Q: What sort of structure am I using in the above outline?
It may also be helpful to make a ‘table’ of the relevant literature, as in the figure below. This will help you get a sense of the methods and results, and how the papers relate, and how to assess the evidence. You may end up putting this in the actual paper.

Consult a survey paper, textbook, or lecture notes that discuss this paper and this topic
Try to find an easier related paper
Ask your supervisor for help; if he or she can
Try to understand what you can; do not try to “fake it”
Do not cite irrelevant literature.
Do not merely list all the papers you could find.
Discuss them, and their relevance to your paper.
What are their strengths and weaknesses? What techniques do they use, and what assumptions do they rely on? How do they relate to each other?
Use correct citation formats.
Try to find original sources (don’t just cite a web link).
Don’t just cut and paste from other sources. And make sure to attribute every source and every quote. Be clear: which part of your paper is your own work and what is cited from others? The penalties for plagiarism can be severe!
How to discuss empirical results: “Causal” estimation, e.g., with Instrumental Variables
Which is the best way to state it? 12
“As I prove in table 2, more lawyers lead to slower growth (as demonstrated by the regression analysis evidence).”
“Table 2 provides evidence that a high share of lawyers in a city’s population leads to slower growth.”
3.“Table 2 shows that a high share of lawyers in a city’s population is correlated with slower growth.”
Which is better? 13
Stating empirical results: descriptive
“Using the US data from 1850-1950, I find that inflation is lower during periods of recession. This is statistically significant in a t-test [or whatever test] at the 99% level, and the difference is economically meaningful. This is consistent with the theory of …, which predicts that lower inflation increases unemployment. However, other explanations are possible, including reverse causality, and unmeasured covarying lags and trends.”
“I find a significantly lower level of inflation during periods of recession, and the difference is economically meaningful. This relationship is statistically significant and the data is accurately measured. Thus I find that inflation increases unemployment.”

Citing your sources is essential in academic writing . Whenever you quote or paraphrase a source (such as a book, article, or webpage), you have to include a citation crediting the original author.
Failing to properly cite your sources counts as plagiarism , since you’re presenting someone else’s ideas as if they were your own.
The most commonly used citation styles are APA and MLA. The free Scribbr Citation Generator is the quickest way to cite sources in these styles. Simply enter the URL, DOI, or title, and we’ll generate an accurate, correctly formatted citation.

Citation examples and full guides, frequently asked questions about citing sources.
Citations are required in all types of academic texts. They are needed for several reasons:
A citation is needed whenever you integrate a source into your writing. This usually means quoting or paraphrasing:
Citations are needed whether you quote or paraphrase, and whatever type of source you use. As well as citing scholarly sources like books and journal articles, don’t forget to include citations for any other sources you use for ideas, examples, or evidence. That includes websites, YouTube videos , and lectures .
Discover proofreading & editing
Usually, your institution (or the journal you’re submitting to) will require you to follow a specific citation style, so check your guidelines or ask your instructor.
In some cases, you may have to choose a citation style for yourself. Make sure to pick one style and use it consistently:
If in doubt, check with your instructor or read other papers from your field of study to see what style they follow.
In most styles, your citations consist of:
In-text citations most commonly take the form of parenthetical citations featuring the last name of the source’s author and its year of publication (aka author-date citations).
An alternative to this type of in-text citation is the system used in numerical citation styles , where a number is inserted into the text, corresponding to an entry in a numbered reference list.
There are also note citation styles , where you place your citations in either footnotes or endnotes . Since they’re not embedded in the text itself, these citations can provide more detail and sometimes aren’t accompanied by a full reference list or bibliography.
(London: John Murray, 1859), 510. |
A reference list (aka “Bibliography” or “Works Cited,” depending on the style) is where you provide full information on each of the sources you’ve cited in the text. It appears at the end of your paper, usually with a hanging indent applied to each entry.
The information included in reference entries is broadly similar, whatever citation style you’re using. For each source, you’ll typically include the:
The exact information included varies depending on the source type and the citation style. The order in which the information appears, and how you format it (e.g., capitalization, use of italics) also varies.
Most commonly, the entries in your reference list are alphabetized by author name. This allows the reader to easily find the relevant entry based on the author name in your in-text citation.
In numerical citation styles, the entries in your reference list are numbered, usually based on the order in which you cite them. The reader finds the right entry based on the number that appears in the text.
Because each style has many small differences regarding things like italicization, capitalization , and punctuation , it can be difficult to get every detail right. Using a citation generator can save you a lot of time and effort.
Scribbr offers citation generators for both APA and MLA style. Both are quick, easy to use, and 100% free, with no ads and no registration required.
Just input a URL or DOI or add the source details manually, and the generator will automatically produce an in-text citation and reference entry in the correct format. You can save your reference list as you go and download it when you’re done, and even add annotations for an annotated bibliography .
Once you’ve prepared your citations, you might still be unsure if they’re correct and if you’ve used them appropriately in your text. This is where Scribbr’s other citation tools and services may come in handy:

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .
The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.
“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .
Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.
Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.
The Scribbr Citation Generator is developed using the open-source Citation Style Language (CSL) project and Frank Bennett’s citeproc-js . It’s the same technology used by dozens of other popular citation tools, including Mendeley and Zotero.

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.
Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.
MLA Style is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.

What is a citation?
A citation is a reference to a source used in your research. It is how you give credit to the author for their creative and intellectual works that you referenced as support for your research. Generally, citations should include author’s name, date, publisher information, journal information and/or DOI (Digital Object Identifier).
What are citation styles?
Citation styles are the formal way that citation information is formatted. It dictates what information is included, how it is ordered as well as punctuation and other formatting. There are many different styles and each mandate order of appearance of information (such as publication date, title, and page numbers following the author name etc), conventions of punctuation, use of italics (and underlining for emphasis) that are particular to their style.
How do I choose a citation style?
There are many different ways of citing resources from your research. The citation style sometimes depends on the academic discipline involved and sometimes depends on the publisher/ place of publishing. For example:
REMEMBER : Ultimately your professor will decide which citation style will be used, remember to consult with your professor to determine what is required in your assignment.
The Library has created a Plagiarism Prevention LibGuide that can help you to avoid accidental plagiarism mistakes. Remember you could be expelled or suspended if found guilty of plagiarism.

Step 4: Write. Be selective. Highlight only the most important and relevant points from a source in your review. Use quotes sparingly. Short quotes can help to emphasize a point, but thorough analysis of language from each source is generally unnecessary in a literature review. Synthesize your sources.
Writing a Literature Review. A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels ...

An APA style paper is organized in the author-date style. This means you cite the author's name and year of publication within the text with an in-text citation. You also include the page number, if appropriate. You then include the full information of that source in a reference list at the end of your paper.
Seen this way, citation is a sophisticated task, requiring in-depth knowledge of the literature in a domain. Citation is more than just referencing; it is how we represent the social construction of knowledge in a field. A citation strategy is any indication in the text about the source and nature of knowledge.
Step 2: Identify the literature. Start by searching broadly. Literature for your review will typically be acquired through scholarly books, journal articles, and/or dissertations. Develop an understanding of what is out there, what terms are accurate and helpful, etc., and keep track of all of it with citation management tools.
