"The Market for Lemons" and asymmetric information Akerlof is perhaps best known for his article, "
The Market for Lemons: Quality Uncertainty and the Market Mechanism", published in the
Quarterly Journal of Economics in 1970, in which he identified certain severe problems that afflict markets characterized by
asymmetric information, the paper for which he was awarded the Nobel Memorial Prize. In
Efficiency Wage Models of the Labor Market, Akerlof and coauthor/wife, Janet Yellen propose rationales for the
efficiency wage hypothesis in which employers pay above the
market-clearing wage, in contradiction to the conclusions of
neoclassical economics. This work introduced
gift-exchange game to economics.
Identity economics Akerlof and collaborator
Rachel Kranton of Duke University have introduced social identity into formal economic analysis, creating the field of
identity economics. Drawing on
social psychology and many fields outside of economics, Akerlof and Kranton argue that individuals do not have preferences only over different goods and services. They also adhere to
social norms for how different people should behave. The norms are linked to a person's
social identities. These ideas first appeared in their article "Economics and Identity", published in the
Quarterly Journal of Economics in 2000.
Reproductive technology shock In the late 1970s, Akerlof's ideas attracted the attention of some on both sides of the debate over legal
abortion. In articles appearing in The
Quarterly Journal of Economics,
The Economic Journal, and other forums, Akerlof described a phenomenon that he labeled "
reproductive technology shock." He contended that the new technologies that had helped to spawn the late twentieth century
sexual revolution, modern contraceptives and legal abortion, had not only failed to suppress the incidence of
out-of-wedlock childbearing but also had actually worked to increase it. According to Akerlof, for women who did not use them, these technologies had largely transformed the old paradigm of socio-sexual assumptions, expectations, and behaviors in ways that were especially disadvantageous. For example, the availability of legal abortion now allowed men to view their offspring as the deliberate product of female choice rather than as the joint product of sexual intercourse. Thus, it encouraged biological fathers to reject not only the notion of an obligation to marry the mother but also the idea of a paternal obligation. While Akerlof did not recommend legal restrictions on either abortion or the availability of contraceptives his analysis seemed to lend support to those who did. Thus, a scholar strongly associated with liberal and Democratic-leaning policy positions has been approvingly cited by conservative and Republican-leaning analysts and commentators.
Looting In 1993 Akerlof and
Paul Romer published "Looting: The Economic Underworld of Bankruptcy for Profit", describing how under certain conditions, owners of corporations will decide it is more profitable for them personally to 'loot' the company and 'extract value' from it instead of trying to make it grow and prosper. For example: Bankruptcy for profit will occur if poor accounting, lax regulation, or low penalties for abuse give owners an incentive to pay themselves more than their firms are worth and then default on their debt obligations. Bankruptcy for profit occurs most commonly when a government guarantees a firm's debt obligations.
Norms and macroeconomics In his 2007 presidential address to the
American Economic Association, Akerlof proposed
natural norms that decision makers have for how they
should behave, and showed how such norms can explain discrepancies between theory and observed facts about the macroeconomy. Akerlof proposed a new agenda for macroeconomics, using social norms to explain macroeconomic behavior. He is considered together with
Gary Becker as one of the founders of
social economics. He is a trustee of
Economists for Peace and Security and co-director of the Social Interactions, Identity and Well-Being Program at the
Canadian Institute for Advanced Research (CIFAR). He is on the advisory board of the
Institute for New Economic Thinking. He was elected a fellow of the
American Academy of Arts and Sciences in 1985. For his work and contribution to economics and philosophy, he was awarded the third Witten Lectures in Economics and Philosophy at the
Witten/Herdecke University in 2009. ==Political views==
