This paper examines moral hazard in teams over time. Agents are collectively engaged in an uncertain project, and their individual efforts are unobserved. Free-riding leads not only to a reduction in effort, but also to procrastination. The collaboration dwindles over time, but never ceases as...

Discussion of Islamic private equity (PE) financing modes rarely provides detailed analytical insights into their properties: there is no rigorous analysis of their features. The current paper analyzes how and when Profit Loss Sharing (PLS) financing methods can solve asymmetric information...

We discuss the difficult question of measuring the effects of asymmetric information problems on resource allocation. Three problems are examined: moral hazard, adverse selection, and asymmetric learning. One theoretical conclusion, drawn by many authors, is that information problems may...

This paper studies the optimal unemployment insurance for older workers in a repeated principal-agent model, where the search intensity of risk-averse workers (the agents) is not observed by the risk-neutral insurance agency (the principal). When unemployment benefits are the only available...

An altruistic agent who may aid a person with a low income may induce that person to exert little effort to increase his income. Such behavior generates a Good Samaritan Dilemma, in which welfare is lower than when no one is altruistic. Governmental transfers, which restrict reallocation from a...

This paper is a first attempt to connect the heterogeneity in bank efficiency with lending fluctuations and allocation efficiency: there is a trade-off between the two in the presence of heterogeneity in bank monitoring efficiency. The mechanism at hand is twofold. (a) First the rent extracted...

Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. With perfect risk classification, premiums fully reflect the expected cost associated...

In this paper we compare the welfare effects of unemployment insurance (UI) with an universal basic income (UBI) system in an economy with idiosyncratic shocks to employment. Both policies provide a safety net in the face of idiosyncratic shocks. While the unemployment insurance program should...

This paper studies the optimal unemployment insurance for older workers in a repeated principal-agent model, where the search intensity of risk-averse workers (the agents) is not observed by the risk-neutral insurance agency (the principal). When unemployment benefits are the only available...

We study a discrete-time model of repeated moral hazard without commitment. In every period, a principal finances a project, choosing the scale of the project and a contingent payment plan for an agent, who has the opportunity to appropriate the returns of a successful project unbeknownst the...
