Cultural and institutional differences among nations may result in differences in the ratios of marginal costs of goods in autarchy and thus be the basis of specialization and comparative advantage, as long as these differences are not eliminated by trade. We provide an evolutionary model of...

Laws and policies designed to harness self-regarding preferences to public ends may fail when they compromise the beneficial effects of pro-social preferences. Experimental evidence indicates that incentives that appeal to self interest may reduce the salience of intrinsic motivation,...

Under conditions of informational asymmetry, redistributing the property rights may improve work incentives but lead to an inefficient choice of entrepreneurial risk. We present a model in which reassignment of property rights does not affect factor prices and we show that there exist...

We explore the dynamics of group inequality when segregation of social networks places the initially less affluent group at a disadvantage in acquiring human capital. Extending Loury (1977), we demonstrate that (i) group differences in economic success can persist across generations in the...

Two basic tenets of theWalrasian model, behavior based on self-interested exogenous preferences and complete and costless contracting have recently come under critical scrutiny. First, social norms and psychological dispositions extending beyond the selfish motives of Homo economicus may have an...

Social preferences such as altruism, reciprocity, intrinsic motivation and a desire to uphold ethical norms are essential to good government, often facilitating socially desirable allocations that would be unattainable by incentives that appeal solely to self-interest. But experimental and other...

Policies and explicit incentives designed for self-regarding individuals sometimes are less effective or even counterproductive when they diminish altruism, ethical norms and other social preferences. Evidence from 51 experimental studies indicates that this crowding out effect is pervasive, and...

A number of outstanding puzzles in economics may be resolved by recognizing that where members of a group benefit from mutual adherence to a social norm, agents may obey the norm and punish its violators, even when this behavior cannot be motivated by self-regarding, outcome-oriented...

We investigate Veblen effects on work hours, namely the way that a desire to emulate the consumption standards of the rich induces longer work hours among the rest. Consistent with our model of these asymmetric social comparisons, greater inequality predicts longer work hours in ten OECD...
