This fall I’m teaching “Economics of Institutions and Organizations” to first-year graduate students. The reading list is rather heavy, compared to what most students are used to from their undergraduate courses and their first-year courses in microeconomics, econometrics, etc. I explain that they need to become not only avid readers, but also efficient readers, able to extract the maximum information from an academic article with the least effort. They need to learn, in other words, the art of the skim.
When I’ve explained this in the past, students have responded that they don’t know how to skim. So a couple years back I put together a little handout, “How to Read an Academic Article,” with a few tips and tricks. I emphasize that I don’t mean to be patronizing, and that they should ignore the handout if its contents seem painfully obvious. But students have told me they really appreciate having this information. So, I reproduce the handout below. Any comments and suggestions for improvement?
How to Read an Academic Article
- Caveat: no single style works for everyone!
- Klein’s basic steps for skimming, scanning, processing…
- Read the abstract (if provided)
- Read the introduction.
- Read the conclusion.
- Skim the middle, looking at section titles, tables, figures, etc.—try to get a feel for the style and flow of the article.
- Is it methodological, conceptual, theoretical (verbal or mathematical), empirical, or something else?
- Is it primarily a survey, a novel theoretical contribution, an empirical application of an existing theory or technique, a critique, or something else?
- Go back and read the whole thing quickly, skipping equations, most figures and tables.
- Go back and read the whole thing carefully, focusing on the sections or areas that seem most important.
- Once you’ve grasped the basic argument the author is trying to make, critique it!
- Ask if the argument makes sense. Is it internally consistent? Well supported by argument or evidence? (This skill takes some experience to develop!)
- Compare the article to others you’ve read on the same or a closely related subject. (If this is the first paper you’ve read in a particular subject area, find some more and skim them. Introductions and conclusions are key.) Compare and contrast. Are the arguments consistent, contradictory, orthogonal?
- Use Google Scholar, the Social Sciences Citation Index, publisher web pages, and other resources to find articles that cite the article you’re reading. See what they say about it. See if it’s mentioned on blogs, groups, etc.
- Check out a reference work, e.g. a survey article from the Journal of Economic Literature, a Handbook or Encyclopedia article, or a similar source, to see how this article fits in the broader context of its subject area.

The New Institutional Economics focuses mainly on formal rules, both “macro” (constitutions, legal systems, written languages) and “micro” (firms, contracts, other formal agreements). But there are many studies of informal or semi-formal constraints — norms, conventions, religion, belief systems, and other aspects of culture, broadly conceived. Given their commitment to methodological individualism, New Institutional Economists tend to explain the emergence and stability of these phenomena as the consequences — typically unintended — of purposeful individual choices (which distinguishes us from our colleagues on the other side of the aisle). (Culture is important within organizations, as well as between them, though attempts to explain organizational culture in this manner have been less successful.)
Does Culture Matter?
This paper reviews the literature on culture and economics, focusing primarily on the epidemiological approach. The epidemiological approach studies the variation in outcomes across different immigrant groups residing in the same country. Immigrants presumably differ in their cultures but share a common institutional and economic environment. This allows one to separate the effect of culture from the original economic and institutional environment. This approach has been used to study a variety of issues, including female labor force participaiton, fertility, labor market regulation, redistribution, growth, and financial development among others.
Do Social Connections Reduce Moral Hazard? Evidence from the New York City Taxi Industry
C. Kirabo Jackson, Henry S. Schneider
This study investigates the role of social networks in aligning the incentives of economic agents in settings with incomplete contracts. We study the New York City taxi industry where taxis are often leased and lessee-drivers have worse driving outcomes than owner-drivers as a result of a moral hazard associated with incomplete leasing contracts. Using instrumental variables and fixed-effects analyses, we find that: (1) drivers leasing from members of their country-of-birth community exhibit significantly reduced effects of moral hazard; (2) network effects appear to operate primarily via social sanctions; and (3) network benefits can help to explain the organization of the industry in terms of which drivers and owners form business relationships.

It must be acknowledged, however, that a researcher’s political ideology or vested interest in a particular theory can still enter even ostensibly descriptive analysis by the data set chosen for the research; the mathematical transformations of raw data and the exclusion of so-called outlier data; the specific form of the mathematical equations posited for estimation; the estimation method used; the number of retrials in estimation to get what strikes the researcher as “plausible” results, and the manner in which final research findings are presented.
That’s Uwe Reinhardt, writing a NY Times op-ed that could have been titled “A Mainstream Economist Tries to Come to Grips with Kaldor-Hicks Efficiency.” It’s actually a pretty thoughtful and informative discussion that exposes some of the fatal — to my mind, anyway — flaws of the Kaldor-Hicks concept. But Reinhardt implies, unfortunately, that virtually every economist accepts the Kaldor-Hicks principle as a normative standard. There is actually a fair amount of dissent, not only from Austrians but also from people like Jon Elster and John Roemer. As Gary Lawson notes in an excellent survey of welfare economics concepts, the Kaldor-Hicks criterion, in practice, is
as useless as Pareto superiority. Kaldor-Hicks efficiency purchases its coherence by requiring that compensation be hypothetically possible in such a way as to guarantee that each person, by her own standards, does not come away a loser, just as strict Paretianism requires that each person judge herself to be as well off or better off than before. All it takes to make the universe of Kaldor-Hicks-efficient transactions an empty set is one person who sincerely cannot be bought-that is, a person who values autonomy, either his own or that of others, so highly that no amount of after-the-fact compensation could possibly leave him as well off as he would have been had the loss never been inflicted. (without consent) in the first place. In a large population, no legal rule [or other reallocation of resources] will ever satisfy the Kaldor-Hicks efficiency criterion.

It’s Beauty Imagined: A History of the Global Beauty Industry by Geoffrey Jones (Oxford University Press, 2010). From the blurb:
This book provides the first authoritative history of the global beauty industry from its emergence in the nineteenth century to the present day, exploring how today’s global giants grew. It shows how successive generations of entrepreneurs built brands which shaped perceptions of beauty, and the business organizations needed to market them. They democratized access to beauty products, once the privilege of elites, but they also defined the gender and ethnic borders of beauty, and its association with a handful of cities, notably Paris and later New York. The result was a homogenization of beauty ideals throughout the world.
Sounds like a great study of entrepreneurship, industry dynamics, clustering and network effects, and the relationship between business and culture. Reviewer Ingrid Giertz-Mårtenson says it’s “one of the more fascinating stories in modern business history,” the journey of an industry once seen as “fickle, superficial, and feminine” to a “brand-driven global power house.” The book should make a beautiful addition to your collection!

I knew that the Victorians had their own Internet, that information goods and open innovation are old hat, and that S-curves go back a hundred years. But apparently the Victorians used texting language too! We instruct our students to avoid it, but apparently Victorian poets thought writing I “love U 2 X S” or “U R virtuous and Y’s” was exceedingly clever. LOL! (Discovery! via Gizmodo.)

This semester I am teaching a PhD course in the Austrian school of economics. Here’s a preview. Visitors to Columbia, Missouri are welcome to sit in!
Excerpt from the syllabus:
It is difficult to cover an entire school of thought in one semester. Austrian economics, after all, is not an applied field like development economics or international trade policy or biotechnology but an alternative approach to all fields of economics. The course objective is not to provide a comprehensive review and critique of the entire Austrian tradition, but to give students a sampler of high-quality Austrian writings, classic and modern, on a variety of issues and topics. One goal is to show that while Austrian economists share a common conceptual framework, theoretical core, and historical context, the Austrian literature contains tremendous variety, both stylistic and substantive. Like any living, breathing tradition the Austrian literature continues to expand and diversify, often at a dizzying pace.

Ronald Coase described his 1937 paper on the firm as “much cited, but little used.” He was referring to the academic literature, but these days it seems to apply to the popular press as well. Almost every week brings a new article on the death of the corporate hierarchy: you know, firms only exist to deal with transaction costs, and the Internet has reduced them to almost zero, so who needs firms? This argument shows up again and again. But it’s wrong. Of course there are transaction costs between firms (search, bargaining, enforcement). But there are also transaction costs inside firms (agency and information costs, the Misesian calculation problem). The firm straddles these margins. Both sets of transaction costs matter, and both can be reduced through technological change. Coase was not as clear on this point as he could have been, but Williamson has been explaining it for decades, in terms of “comparative contracting costs.” You have to compare both sets of costs, not just look at one. Why is it so hard to see?
Saturday’s WSJ gives us the latest version of the bogus argument, this time from Alan Murray. Same old story: Internet, transaction costs, Tapscott and Williams, wikipedia, yada yada yada. “Mr. Coase received his Nobel Prize in 1991 — the very dawn of the Internet age. Since then, the ability of human beings on different continents and with vastly different skills and interests to work together and coordinate complex tasks has taken quantum leaps. Complicated enterprises, like maintaining Wikipedia or building a Linux operating system, now can be accomplished with little or no corporate management structure at all.” Yawn. “[T]he trends here are big and undeniable. Change is rapidly accelerating. Transaction costs are rapidly diminishing. And as a result, everything we learned in the last century about managing large corporations is in need of a serious rethink.” Zzzzzzzzzzzzzzz. Mr. Murray, please read The Victorian Internet three times fast and have a report on my desk first thing in the morning. “The new model will have to be more like the marketplace, and less like corporations of the past. It will need to be flexible, agile, able to quickly adjust to market developments, and ruthless in reallocating resources to new opportunities.” Right, no corporations of the past ever tried to do this.
