In a context of vertical product differentiation we analyze the effect of delegation on quality. We consider a duopoly where firms can delegate to an agent the quality determining activities. The quality level is determined by the level of a random fixed cost. The actual realization of this...

The present work analyzes the effect of competition on managerial incentives when agents have private information about the firms' productivities. Two types of firms are considered: managerial firms (delegation) and entrepreneurial firms (no delegation). Due to the asymmetry of information...

In a context of asymmetry of information between firms' owners and their managers, we investigate the use of incentive contracts as strategic variables in an oligopoly industry. Moreover, we consider that the government has the possibilityto intervene in the market by nationalizing an incumbent...

In this paper we analyse educational choices and earnings of individuals at two different levels in the Portuguese educational system. At each potential exit level we consider two decisions: the decision to continue studying and the employment decision, whereas normally only the first decision...

We study employment dynamics using an OLG model with unemployment benefits and universal old-age survival pensions, both financed by taxing employed workers. The novelty is that we explicitly introduce workers' social norms that shape both the individual participation decision of workers and...

In this paper we conduct an analysis of the effects of firing costs in models that consider simultaneously worker heterogeneity, imperfect information on their productivity and union power. We consider an OLG model where heterogeneous workers participate in the labour market both when young and...

In this paper we conduct a theoretical analysis of the implications of a union which can exploit the existence of firm labour adjustment costs. We consider a model involving a large number of identical firms facing a single, economy-wide union. We solve (i) for the Markov perfect equilibria with...

We analyse the implications of unions (efficient bargaining) for multiplicity of stationary states and welfare, local indeterminacy, bifurcations and endogenous fluctuations (deterministic and stochastic). We use an overlapping generations model with external increasing returns to scale, where...
