Fixed price equilibria in a multifirm model
Abstract In a simple temperary equilibrium model with three commodities (labour, goods and money) and two sectors, there are different firms, each having its own production function. There now exist four types of fixed price equilibria (Keynesian, classical, repressed inflation, undercounsumption). In the last type, consumers are not rationed, some producers are rationed on the goods market, and other producers on the labour market. There exist three different aggregate production functions, that have to be applied in Keynesian, classical, and repressed inflation situations respectively. For the fourth case no aggregate production function exists.
