We specify an empirical framework to detect the effects of official intervention on real exchange rate dynamics. Using data for 27 advanced and emerging market economies, we find evidence that interventions are a near-universal practice; almost all countries intervene when real exchange rates...

Location-specific norms of behavior are a widespread phenomenon. In the case of medical practice, numerous studies have found that geographic location exerts a strong influence on the choice of treatments and procedures. This paper shows how the presence of social influence on treatment...

We develop a model of contracting in which individual effort choices are subject to social pressure to conform to the average effort level of others in the same risk-sharing group. As in related models of social interactions, a change in exogenous variables or contract terms generates a social...

We investigate the effect of increasing the information endowment of customers in markets where experts provide both a diagnosis and the service under two alternative institutions: customers may either directly acquire information through personal research (PR) before consulting the expert or...

We develop a model of occupational choice and entrepreneurship in which market frictions limit the possibilities for diversifying entrepreneurial risk. A concern for relative standing arises in this model even though individuals care only about the consumption of standard commodities. In...

A standard approach in economic theory is to use a formal language to prove results about an economy or a game. In this paper, model theory is used to examine interpretations of such results. The particular focus is on constructive theorems, since results established by constructive methods are...

This paper evaluates the extent of regulation in a democracy with political corruption. Elected politicians can restrict entry of firms in exchange for bribes from entrepreneurs. Full liberalisation implies free entry and allocative efficiency and is supported by a majority of voters. Voters...

This paper develops a theory of policy myopia. Policy myopia arises when rational voters set performance standards that allow elected politicians to distort the portfolio of public investments towards short-term investments. We show that the fact that voters cannot observe immediately how much...
