We analyze optimal taxation in an economy with monopsonistic labour markets. The individuals, whose only decisions are whether to work, or not, have heterogeneous productivities and opportunity costs of work. Given its preferences for redistribution, the government, which does not observe the...

We show the existence of a twin peaks relation between trust and the size of the welfare state that stems from two opposing forces. Uncivic people support large welfare states because they expect to benefit from them without bearing their costs. But civic individuals support generous benefits...

This paper provides a simple model which explains the choice between permanent and temporary jobs. This model, which incorporates important features of actual employment protection legislations neglected by the economic literature so far, reproduces the main stylized facts about entries into...

This survey reviews the recent research on trust, institutions and economic development. It discusses the various measures of trust and documents the substantial heterogeneity of trust across space and time. The conceptual mechanisms that explain the influence of trust on economic performance...

We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading requires specialized intermediaries and where agents freely choose between working in the production or in the financial sector. Frictions in the market for deposits create...

The systematic use of experience rating is an original feature of the US unemployment benefit system. In most states, unemployment benefits are financed by taxing firms in proportion to their separations. Experience rating is a way to require employers to contribute to the payment of...

The Nash wage bargaining model is ubiquitous in modern labour economics. Yet most applications of this model ignore inter-employer competition for labour services and attribute all of the workers’ rent to their bargaining power. In this Paper, we write and estimate an equilibrium model with...

This paper analyses optimum income taxation in a model with endogenous job destruction that gives rise to unemployment. It is shown that optimal tax schemes comprise both payroll and layoff taxes when the state provides public unemployment insurance and aims at redistributing income. The optimal...

In search of a macroeconomic theory of wage determination, the agnostic reader should be puzzled by the apparent contradiction between two influential theories. On one hand, in the standard search-matching theory with wage bargaining, hiring cost and constant returns of labour, the bargaining...

This Paper provides a simple matching model in which unemployed workers and employers can be matched together through social networks and through more efficient, but also more costly, methods. In this framework, decentralized decisions to utilize social networks in the job search process can be...
