In most firms a worker in any period is either promoted, left in the same job, or fired (demotions are typically rare), and there is no specific date by which a promotion needs to occur. In other employment situations, however, up-or-out contracts are common, i.e., if a worker is not promoted by...

In this paper we develop a two period model of a credit market to study the interaction between a monopolistic moneylender and a subsidized microfinance institution. We assume that lenders face a moral hazard problem that is diminished as agents are able to take increased equity positions in...

This paper builds a theoretical model to address evidence on labor mobility patterns in technology-intensive firms engaged in R&D. Labor turnover in these firms is characteristically different from turnover in traditional industries both in size and composition. Specifically, the pool of workers...

In this paper, we study supplier–firm interactions to explain firms' outsourcing relationships. We show that in an imperfect information setup a firm learns about the quality of its suppliers through repeated interaction. As the firm determines the suppliers' quality with greater precision, it...

We extend the model of voluntary contributions to multiple public goods by allowing for bundling of the public goods. Specifically, we study the case where agents contribute into a common pool which is then allocated towards the financing of two pure public goods. We explore the welfare...

We show that a seemingly paradoxical result is possible—an increase in one's wage can reduce one's welfare. Such outcome can occur in an economy populated by agents who value a private good bought using labor income and a public good produced by voluntary time contributions. A raise in the...

This paper investigates whether donor contributions to charities responds to the information incorporated in charity ratings. Using charity ratings data from 1999-2004, we find that ratings do have a significant effect on contributions received. We find that charities that have the lowest rating...

This paper presents a theoretical model that combines employers learning about worker productivity, human capital acquisition, job-assignment and resolution of worker uncertainty regarding disutility of work from a job, to show how widely documented findings on both wage and promotion dynamics...

In this paper we offer a theoretical examination of the phenomenon known as mission drift. In recent years there have been claims that the entry of large donors with deep pockets have led to a mission drift phenomenon, whereby microfinance institutions who were previously catering to the poorest...
