Models on private provision of public goods typically involve a single private good and linear production technology for the public good. We study a model with several private goods and non-linear (strictly concave) production technology. We revisit the question of “neutrality” of government...

In this paper the existence of unemployment is partly explained as being the result of coordination failures. It is shown that as a result of self-fulfilling pessimistic expectations, even at Walrasian prices, a continuum of equilibria results, among which an equilibrium with approximately no...

The purpose of the paper is to argue that exogenous changes lowering wages may imply an increase of unemployment. To support that viewpoint, we use a general equilibrium approach. In that framework, we substitute the labour market clearing equation, which by very definition insures full...
