We analyze a dynamic principal-agent problem in which the agent's effort in each period has strong persistent effects. We show that a simple contract, where the reward depends only on the final outcome, is explained as the optimal contract derived in the principal's optimization problem. The...

If potential donors for a charity project possess the warm-glow properties in their preferences, we can represent their behavior with a coordination game. Accordingly, we construct a simultaneous incomplete information game model of charitable giving based on a simple global coordination game....

There is evidence that young mothers do not have the opportunity to accumulate human capital for themselves, which can have a negative effect on theirchildren's outcomes. This study investigates the effect of young maternal ageon children's educational level. No significant direct effect of...

This paper studies how media and democracy influence government action taken before and after a natural disaster. The key elements in this relationship are the media's role as the provider of information to voters about government actions and the quality of democracy that pertains to how...

This paper investigates whether smokers exhibit greater time discounting than non-smokers, and how short-term nicotine deprivation affects time discounting. A unique feature of our experiment is that our subjects receive rewards not only of money, but also of actual tobacco. This is done in...

We study structural change in a simple, two-sector endogenous growth model and show that the presence of commodity-specific consumption externalities can be a source of structural change. When the degrees of consumption externalities are different between different goods, the two sectors grow at...

We provide a theoretical framework to discuss the relation between market size and vertical structure in the railway industry. The framework is based on a simple downstream monopoly model with two input suppliers, labor forces and the rail infrastructure firm. The operation of the downstream...

Analysis of an original, broad, internet-based survey reveals that debt holding is related to three aspects of time discounting: (i) present bias, measured by the degree of declining impatience in the generalized hyperbolic discount function; (ii) borrowing aversion, captured by a sign effect -...

In this paper, we present data on trends over time in domestic saving rates in twelve economies in developing Asia during the 1966-2007 period and analyze the determinants of these trends. We find that domestic saving rates in developing Asia have, in general, been high and rising but that there...

We provide a simple theoretical model to explain the mechanism wherebyprivatization of international airports can improve welfare. The model consists of a downstream (airline) duopoly with two inputs (landings at two airports) andtwo types of consumers. The airline companies compete...
