We show that an agent maximizing some utility function on a discrete (as opposed to continuous) consumption space will obey the generalized axiom of revealed preference (GARP) so long as the agent obeys cost efficiency. Cost efficiency will hold if there is some good, outside the set of goods...

Students in Brazil are typically assigned to classes based on their age ranking in their school grade. I exploit this rule to estimate the effects on maths achievement of being in a class with older peers for students in fifth grade of primary school. Because grade repetition is widespread in...

This paper examines the optimal entry policy towards oligopoly in an globalized world. In an open economy free entry is socially suboptimal, but corrective tax policy to curb entry proves insufficient unless internationally harmonized. Thus, while conferring the gains from trade, globalization...

Empirical work on Akerlof’s theory of gift exchange in labor markets has concentrated on the fair wage-effort hypothesis. In fact, however, the theory also contains a social component that stipulates that homogenous agents that are employed for the same wage level will exert more effort,...

The compensation of executive board members in Germany has become a highly controversial topic since Vodafone's hostile takeover of Mannesmann in 2000 and it is again in the spotlight since the outbreak of the financial crisis of 2009.

We propose a theory of ex post inefficient renegotiation that is based on loss aversion. When two parties write a long-term contract that has to be renegotiated after the realization of the state of the world, they take the initial contract as a reference point to which they compare gains and...

This paper models the decision to quit smoking like an investment decision where the quitter incurs a sunk withdrawal cost today and forgoes their consumer surplus from cigarettes (invests) and hopes to reap an uncertain reward of better health and therefore higher utility in the future...

This paper makes the following point: “detracking” schools, that is preventing them from allocating students to classes according to their ability, may lead to an increase in income residential segregation. It does so in a simple model where households care about the school peer group of...

The paper reviews the theoretical and the empirical case for public investment in education in India. Though the theoretical literature provides a backing for such a policy, the empirical literature fails to find a robust relation between education expenditure and growth. Expenditure on...

The paper tests the effectiveness of marginal reserve requirements employed by the Japanese authorities in the 1970s to influence short-term capital flows, thereby contributing to the ongoing debate on the use of capital controls\market- or price-based ones in particular. While the case for...
