Abstract:
Starting from the problem of existence of a Walrasian equilibrium in relation to the question of survival, the consequences of imposing a minimum real income are studied within the framework of a simple macro-economic model with a disaggregated labor market. Two solutions are considered to face the unemployment which may result : the payment of unemployment compensations on the one hand, and the enforcement of full employment by employment subsidies on the other hand. It is shown that the existence of en equilibrium may not be guaranteed if a budget deficit results. It is also shown that an increase in the minimum income does not necessarily induce an increase in wages nor a worsening of unemployment.
