Stakes Matter in Ultimatum Games

By Steffen Andersen, Seda 贰谤迟补莽, Uri Gneezy, Moshe Hoffman, and John A. List

蝌蚪网 Review, December 2011

One of the most robust findings in experimental economics is that individuals in one-shot ultimatum games reject unfair offers. Puzzlingly, rejections have been found robust to substantial increases in stakes. By using a novel experimental design that eli...

By 慕耻产辞拧 笔谩蝉迟辞谤 and Pietro Veronesi

蝌蚪网 Review, September 2009

Stochastic Choice: An Optimizing Neuroeconomic Model

By Michael Woodford

蝌蚪网 Review, May 2014

A model is proposed in which stochastic choice results from noise in cognitive processing rather than random variation in preferences. The mental process used to make a choice is nonetheless optimal, subject to a constraint on available information-proces...

Capital Account Liberalization: Theory, Evidence, and Speculation

By Peter Blair Henry

Journal of Economic Literature, December 2007

Research on the macroeconomic impact of capital account liberalization finds few, if any, robust effects of liberalization on real variables. In contrast to the prevailing wisdom, I argue that the textbook theory of liberalization holds up quite well to...

By Hilary Hoynes, Doug Miller, and David Simon

蝌蚪网 Journal: Economic Policy, February 2015

This paper uses quasi-experimental variation from federal tax reform to evaluate the effect of the EITC on infant health outcomes. We find that the EITC reduces the incidence of low birth weight and increases mean birth weight: a $1,000 treatment-on-the-t...

By Joshua Angrist, Eric Bettinger, and Michael Kremer

蝌蚪网 Review, June 2006

Colombia's PACES program provided over 125,000 poor children with vouchers that covered the cost of private secondary school. The vouchers were renewable annually conditional on adequate academic progress. Since many vouchers were assigned by lottery, pro...

By Eric French and Jae Song

The Contribution of Large and Small Employers to Job Creation in Times of High and Low Unemployment

By Giuseppe Moscarini and Fabien Postel-Vinay

蝌蚪网 Review, October 2012

We document a negative correlation, at business cycle frequencies, between the net job creation rate of large employers and the level of aggregate unemployment that is much stronger than for small employers. The differential growth rate of employment betw...

The Home-Market Effect and Bilateral Trade Patterns

By Gordon H. Hanson and Chong Xiang

蝌蚪网 Review, September 2004

We develop a monopolistic-competition model of trade with many industries to examine how home-market effects vary with industry characteristics. Industries with high transport costs and more differentiated products tend to be more concentrated in large co...

Journal of Economic Perspectives, Winter 2006

Between 1950 and 2000, the four-firm producer-concentration ratio for beer increased from 22 to 95 in the United States; and Anheuser-Busch's share of domestic output ballooned from 6 to 54 percent. In Germany, concentration has risen, but it remains low....

By Adriaan R. Soetevent

蝌蚪网 Journal: Economic Policy, February 2011

The Social Cost of Near-Rational Investment

By Tarek A. Hassan and Thomas M. Mertens

蝌蚪网 Review, April 2017

We show that the stock market may fail to aggregate information even if it appears to be efficient, and that the resulting decrease in the information content of prices may drastically reduce welfare. We solve a macroeconomic model in which information ab...

A Theory of Military Dictatorships

By Daron Acemoglu, Davide Ticchi, and Andrea Vindigni

蝌蚪网 Journal: Macroeconomics, January 2010

We investigate how nondemocratic regimes use the military and how this can lead to the emergence of military dictatorships. The elite may build a strong military and make the concessions necessary for the military to behave as their perfect agent, or t...
