This paper provides a tractable search model with divisible money that encompasses the two frameworks currently used in the literature. Individuals belong to many villages. Inside a village, individuals know each other so financial contracts are feasible. Money is essential to facilitate trade...

This is a comment on the work of Rocheteau and Wright (2005) who have recently introduced competitive search into monetary economics. We extend their work by eliminating the restriction that the fees market makers charge to enter a submarket must be either non-negative or identical for buyers...

This paper provides a tractable search model with divisible money that encompasses the two frameworks currently used in the literature. In the model, individuals belong to many villages. Inside a village, individuals are not altruistic as in a representative household, but they share information...

After a brief recent empirical sketch of Islamic finance, the paper turns to its main theoretical and conceptual purpose. It seeks to relate the concepts of Islamic and conventional finance, and to examine certain important questions which arise from the interaction between these systems. The...

Evidence suggests that unemployed individuals can sometimes affect their job prospects by undertaking a costly action like deciding to move or retrain. Realistically, such an opportunity only arises for some individuals and the identity of those may be unobservable ex-ante. The problem of...

This paper provides a selective review of the theoretical literature on delegated portfolio management as a principal-agent relationship. The main focus of the paper is to review the analytical issues raised by the peculiar nature of the delegated portfolio management relationship within the...

Market based instruments are proving increasingly effective in biodiversity procurement and in regulatory schemes to preserve biodiversity. The design of these policy instruments brings together issues in auction design, contract theory, biology, and monitoring technology. Using a mixed adverse...

Information asymmetries are important in theory but difficult to identify in practice. We estimate the presence and importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major...

This paper looks at social insurance of short term absence from work. The chief concern is with efficiency properties of full coverage. That arrangement is reviewed and criticized here in light of received theory. A main point is that positive loading of the premium implies less than full...

This paper addresses the class of generalized agency problems: situations in which adverse selection and moral hazard are jointly present. We present a decomposition of the principal's optimization problem under the first-order approach that sheds light on the interactions between the two types...
