We study the tension between competitive screening and contract enforcement where a principal trades repeatedly with one among several agents, moral hazard and adverse selection coexist, and non-contractible dimensions are governed by relational contracting. We simultaneously characterize...

The missing wage rigidity in general equilibrium models of efficiency wages is an artifact of the external wage reference perspective conventionally adopted by the literature. Efficiency wage models based on an internal wage reference perspective are capable of generating strong wage rigidity....

We develop a reciprocity-based model of wage determination and incorporate it into a modern dynamic general equilibrium framework. We estimate the model and find that, among potential determinants of wage policy, rent-sharing (between workers and firms) and a measure of wage entitlement are...

We build a New Keynesian model of the business cycle with sticky prices and real wage rigidities motivated by efficiency wages of the gift exchange variety. Compared to a standard sticky price model, our Fair Wage model provides an explanation for structural employment and generates more...

This paper analyses the impact of labour demand and labour market regulations on the corporate structure of fims. It finds that higher wages are associated with lower monitoring, irrespective of whether these high wages are caused by labour market regulations, unions or higher labour demand....

We develop and analyse a structural model of efficiency wages founded on reciprocity. Workers are assumed to face an explicit trade-off between the disutility of providing effort and the psychological benefit of reciprocating the gift of a wage offer above some reference level. The model...

We develop a regional model where, in the city, unemployment prevails because of too high (efficiency) wages, while, in the rural area, workers are paid at their marginal productivity. We characterize the steady-state equilibrium and show that it is unique. We then consider two policies:...

In this Paper survey some recent developments in urban labour economic theory. We first present a benchmark model in which firms set efficiency wages to prevent shirking and to compensate workers for commuting. We show that both wages and unemployment depend on commuting costs, and that housing...

Recent empirical work has shown that there exists a negative relation between wages and unemployment estimated across regions. Our model recognizes the spatial dimension of the so-called wage-curve by using a Hotelling/Salop framework in which a finite number of firms compete for heterogeneous...
