We endogenize separation in a search model of the labor market and allow for bargaining over the continuation of employment relationships following productivity shocks to take place under asymmetric information. In such a setting separation may occur even if continuation of the employment...

We analyse a search model of the labour market in which firms and workers meet bilaterally and negotiate over wages in the presence of private information. We show that a fall in labour market frictions induces more aggressive wage bargaining behaviour, which in turn leads to a costly increase...

We analyse a monopolistically competitive model of international trade where goods must be consumed in indivisible amounts. The number of varieties that enter a consumer''s optimal consumption bundle is increasing in the consumer''s per capita income. We first show that, for a given level of...

We analyse the optimal delegation of decision rights by a uninformed principal to an informed but biased agent. When the principal cannot use message-contingent transfers, she offers the agent a set of decisions from which he can choose his preferred one. We fully characterize the optimal...

We examine the relationship between the organization of a multi-divisional firm and its ability to adapt production decisions to changes in the environment. We show that even if lower-level managers have superior information about local conditions, and incentive conflicts are negligible, a...

We analyse the design of decision rules by a principal who faces an informed but biased agent and who is unable to commit to contingent transfers. The contracting problem reduces to a delegation problem in which the principal commits to a set of decisions from which the agent chooses his...
