We study ex-post hiring risks in low income countries with limited legal and regulatory frameworks. In our theory of employee referral, the new re- cruit internalises the rewards and punishments of the in-house referee meted out by the hiring firm. This social mechanism makes it cheaper for the...

The use of social networks in the workplace has been documented by many authors, although the reasons for their widespread prevalence are less well known. In this paper we present evidence based on a combined eld-laboratory experiment that social networks are used by employers to reduce worker...

In a simple model of currency crises caused by creditor coordination failure, we show that bailouts that reduce ex post inefficiency will sometimes create ex ante moral hazard but will sometimes enhance the incentives for governments to take preventative actions. This model helps us understand a...

We study optimal contracting in team settings, featuring stylized aspects of production environments with complex tasks. Agents have many opportunities to shirk, task-level monitoring is needed to provide useful incentives, and because it is difficult to write individual performance into formal...

This paper assesses the merits of countercyclical bank balance sheet regulation for the stabilization of financial and economic cycles and examines its interaction with monetary policy. The framework used is a dynamic stochastic general equilibrium model with banks and bank capital, in which...

The use of social networks in the workplace has been documented by many authors, although the reasons for their widespread prevalence are less well known. In this paper we present evidence based on a lab experiment that suggests quite strongly that social networks are used by employers to reduce...

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...

The identification of information problems in different markets is a challenging issue in the economic literature. In this paper, we study the identification of moral hazard from adverse selection and learning within the context of a multi-period dynamic model. We extend the model of Abbring et...
