Most economic models are based on the self-interest hypothesis that assumes that all people are exclusively motivated by their material self-interest. In recent years experimental economists have gathered overwhelming evidence that systematically refutes the self-interest hypothesis and suggests...

We show that concerns for fairness may have dramatic consequences for the optimal provision of incentives in a moral hazard context. Incentive contracts that are optimal when there are only selfish actors become inferior when some agents are concerned about fairness. Conversely, contracts that...

We incorporate trade in tasks à la Grossman and Rossi-Hansberg (2008) into a small open economy version of the theory of firm organization of Marin and Verdier (2012) to examine how offshoring affects the way firms organize. We show that the offshoring of production tasks leads firms to...

This paper develops a novel approach to modeling references in monopolistic competition models with a continuum of goods. In contrast to the commonly used CES preferences, which do not capture the effects of consumer income and the intensity of competition on equilibrium prices, the present...

There is strong evidence that different income groups consume different bundles of goods. This evidence suggests that trade liberalization can affect welfare inequality within a country via changes in the relative prices of goods consumed by different income groups (the price effect). In this...

There is strong empirical evidence that countries with lower per capita income tend to have smaller trade volumes even after controlling for aggregate income. Furthermore, poorer countries do not just trade less, but have a lower number of trading partners. In this paper, I construct and...

This paper quantitatively explores the role of the demand structure in explaining the relationship between an importer's per capita income and the extensive margin of bilateral trade. The underlying mechanism is based on the fact that agents expand the set of goods they consume with income. This...
