We look for a theoretical justification of nominal wage contracts in household diversification of risk. We assume it is more costly for households than for firms to use financial markets for this purpose. In a calibrated general equilibrium model we find from stochastic simulation that if both...

A dynamic stochastic model of a small open monetary economy with infinitely-lived optimizing households is constructed. There are temporary nominal rigidities in the labour market, while in goods and asset markets prices are flexible. Optimizing behaviour in the foreign country is also modelled....

A dynamic, stochastic optimizing macromodel with predetermined money wages and labour market monopoly power is used to examine the effect on current macroeconomic variables of a temporary increase in variability of the future money supply. As a benchmark, we show that under perfect wage-price...

The evidence from many experiments suggests that people are heterogeneous with regard to their abilities to make rational, forward looking, decisions. This raises the question when the rational types are decisive for aggregate outcomes and when the boundedly rational types shape aggregate...
