We investigate the existence conditions of involuntary unemployment in an overlapping generations model with an imperfect output market. At the temporary equilibrium, unemployment is involuntary if it exists whatever the nominal wage. The study of the price-elasticity components gives us two...

We consider a simple general equilibrium model with imperfect competition on the labor market. We show that on this market a rise in the number of trade unions may reduce the employment level. This result depends on the properties of the nominal wage-elasticity of the labor demand. It is...

This paper examines underemployment fluctuations in an OG model with cournotian competition on the market for a good. In the case of constant returns, it demonstrates the existence conditions of a stable two-period cycle (in prices and employment amounts) in the backward perfect foresight...
