The paper fully characterizes the Bertrand equilibria of oligopolistic markets where consumers may ignore the last (i.e. the right-most) digits of prices. Consumers, in this model, do not do this reflexively or out of irrationality, but only when they expect the time cost of acquiring full...

Previous papers on time-inconsistent procrastination assume projects are completed once begun. We develop a model in which a person chooses whether and when to complete each stage of a long-term project. In addition to procrastination in starting a project, a naive person might undertake costly...

Search is embedded in an overlapping-generations model. The young participate in a centralized market, and then are matched in pairs in a decentralized market. The old only participate in the centralized market. If the buyer's bargaining power is sufficiently close to unity in pairwise trade and...

This paper presents a flexible-price small open economy model with a "peso problem" in productivity states. Agents rationally adjust their beliefs about future productivity growth after the arrival of news. A downward revision of expectations triggers a Sudden Stop, together with large declines...

The links between foreign aid and policies in developing countries have been at the forefront of the policy debate for decades. An emerging consensus touts aid selectivity as the solution to the failures of conditionality. In recent years, many recipients have implemented political reforms...

This paper addresses the problem of data errors in discrete variables. When data errors occur, the observed variable is a misclassified version of the variable of interest, whose distribution is not identified. Inferential problems caused by data errors have been conceptualized through...

Some studies on child labor have shown that greater land wealth leads to higher child labor, thereby casting doubt on the hypothesis that child labor is caused by poverty. This paper argues that the missing ingredient is an explicit modeling of the labor market. We develop a simple model which...

Traditional models of bank runs do not allow for herding effects, because in these models withdrawal decisions are assumed to be made simultaneously. I extend the banking model to allow a depositor to choose his withdrawal time. When he withdraws depends on his liquidity type (patient or...

We analyze an economy with banks and markets and uncover implications of the presence of asset markets for the run-prone banking sector. Consumers can split their endowment between a market investment and a deposit contract which admits bank runs. Banks specialize in providing ex ante liquidity...

Firms often give away free goods with the product that they sell. Firms often give stock options to their top management and other employees. Mixing these two practices--giving stock options to consumers who buy the firm's product--, creates a deadly brew. Large numbers of consumers can be lured...
