Urging Economists to Step Away From the Blackboard

Ronald Coase published his career-making paper, The Nature of the Firm, 75 years ago. He won the Nobel prize for economics in 1991. In a lecture in 2002, he argued that physics has moved beyond the assumptions of Isaac Newton, and biology beyond Darwin. (Not that he knew them.) But economics, he said, had failed to advance past the efficient-market assumptions of Adam Smith. This year Coase, a professor emeritus at the University of Chicago Law School, is attempting to start a new academic journal ambitiously titled Man and the Economy. The premise: Economics is broken. Coase’s journal is still just a plan, but his frustration with orthodox economics has energized his followers.

The financial crisis forced economists to confront the limitations of their profession. Former Federal Reserve Chairman Alan Greenspan admitted as much when he told Congress in October 2008 that markets might not regulate themselves after all. Coase says the problem runs deeper: Economists study abstractions and numbers, instead of firms and people. He doesn’t believe this can be fixed by tweaking models. An entire generation of economists must be encouraged to think differently.

The idea for the journal stems from his collaboration with Ning Wang, an assistant professor at the School of Politics and Global Studies at Arizona State University who grew up in a rice- and fish-farming village in the Hubei province of China. Coase, 101, began working with Wang in the 1990s at the University of Chicago. Neither has a degree in economics; the two understood each other. “We’re not constrained by a mainstream, orthodox view,” says Wang. “A lot of people would see this as a weakness.” Coase declined to be interviewed.

When Coase and Wang hosted a conference on China in 2008, they noticed that many Chinese academics had never talked to either policymakers or entrepreneurs from their own country. They had learned only what Coase calls “blackboard economics,” sets of theories and mathematical relationships between bits of data. “I came from China,” says Wang. “We have a lot of nationals come here; they’re taught game theory and econometrics. Then they’re going home … without a basic understanding of how the real world functions.”

In an essay published on Nov. 20 in Harvard Business Review, Coase argues that in the early 20th century, economists began to focus on relationships among statistical measures, rather than problems that firms have with production or people have with decisions. Economists began writing for each other, instead of for other disciplines or for the business community. “It is suicidal for the field to slide into a hard science of choice,” Coase writes in HBR, “ignoring the influences of society, history, culture, and politics on the working of the economy.” (By “choice,” he means ever more complex versions of price and demand curves.) Most economists, he argues, work with measures like gross domestic product and the unemployment rate that are too removed from how businesses actually work.

Timur Kuran, "The Long Divergence: How Islamic Law Held Back the Middle East"

Princeton University Press
2010

In the year 1000, the economy of the Middle East was at least as advanced as that of Europe. But by 1800, the region had fallen dramatically behind--in living standards, technology, and economic institutions. In short, the Middle East had failed to modernize economically as the West surged ahead. What caused this long divergence? And why does the Middle East remain drastically underdeveloped compared to the West? In The Long Divergence, one of the world's leading experts on Islamic economic institutions and the economy of the Middle East provides a new answer to these long-debated questions.

Timur Kuran argues that what slowed the economic development of the Middle East was not colonialism or geography, still less Muslim attitudes or some incompatibility between Islam and capitalism. Rather, starting around the tenth century, Islamic legal institutions, which had benefitted the Middle Eastern economy in the early centuries of Islam, began to act as a drag on development by slowing or blocking the emergence of central features of modern economic life--including private capital accumulation, corporations, large-scale production, and impersonal exchange. By the nineteenth century, modern economic institutions began to be transplanted to the Middle East, but its economy has not caught up. And there is no quick fix today. Low trust, rampant corruption, and weak civil societies--all characteristic of the region's economies today and all legacies of its economic history--will take generations to overcome.

The Long Divergence opens up a frank and honest debate on a crucial issue that even some of the most ardent secularists in the Muslim world have hesitated to discuss.

Timur Kuran is professor of economics and political science and the Gorter Family Professor of Islamic Studies at Duke University. He is the author of Islam and Mammon: The Economic Predicaments of Islamism (Princeton).

Data protection at the cost of economic growth?

by Elina Pyykko

Centre for European Policy Studies
November 16, 2012

The Data Protection Regulation proposed by the European Commission contains important elements to facilitate and secure personal data flows within the Single Market. A harmonised level of protection of individual data is an important objective and all stakeholders have generally welcomed this basic principle. However, when putting the regulation proposal in the complex context in which it is to be implemented, some important issues are revealed. The proposal dictates how data is to be used, regardless of the operational context. It is generally thought to have been influenced by concerns over social networking. This approach implies protection of data rather than protection of privacy and can hardly lead to more flexible instruments for global data flows.

For Investors, Costly Academic Studies

by Daniel Akst

Wall Street Journal
November 7, 2012

A wide variety of investment strategies are described in the finance literature, but they do have something in common: after the professors write about them, returns are diminished.

That’s the finding of a couple of finance professors who looked at 82 market anomalies exploited by investors and then described in academic papers. In a working paper, the authors estimate that “the average anomaly’s post-publication return decays by about 35%.”

Mostly this seems to be the result of investors learning about the strategy from the academic papers and trading on it, thereby diminishing the precious anomaly in just the way markets are supposed to work. The effect is most pronounced, the professors write, “in large market capitalization stocks, high dollar volume stocks, low idiosyncratic risk stocks, and stocks that pay dividends.”

The End of ‘Marriage’

by Laurie Shrage

New York Times
November 4, 2012

The institution of marriage has become the focus of public debate and reform, not just in the state-by-state political battles familiar to us in the United States, but across the world. Some of the longstanding practices currently being scrutinized both here and in other countries include parental approval in the choice of a spouse, permission for a husband to take more than one wife (polygyny), temporary marriage, close relative (incestuous) marriage, strict or permissive divorce terms, mandatory bride virginity, child marriage or betrothal and gender-structured marriage in which wives and husbands have different duties and privileges and therefore must be gender “opposites.”

Marriage reform is typically part of a larger agenda for social change. In earlier eras, challenges to bans on interfaith and interracial marriage were tied to political movements promoting religious, ethnic and racial equality and social integration. In the Middle East, Africa and Asia today, marriage reformers often aim to expand the rights and liberty of girls and women, while in the Americas and Europe, their primary aim is to advance social equality and respect for lesbians and gay men.

While marriage reform is moving forward in many countries (for example, to extend access to same-sex couples), many prominent legal and political theorists — such as Cass Sunstein, Richard Thaler, Martha Fineman, Tamara Metz, Lisa Duggan, Andrew March, and Brook Sadler (to name only some of those who have put their views in writing) — are proposing that the institution of marriage be privatized. More specifically, they propose that we eliminate the term “marriage” from our civil laws and policies, and replace it with a more neutral term, such as “civil union” or “domestic partnership.” The state would then recognize and regulate civil unions rather than civil marriage, and people would exchange marriage-like rights and duties by becoming “civilly united.” Some private organizations, such as religious institutions, might still perform and solemnize marriages among their congregants, but these marriages would have no official state recognition.
