In decentralised market economies, supply-constrained equilibria may persist as coordination failures, sustained but not caused by price rigidities. This feature may be arbitrarily severe, even at prices com- patible with competitive equilibrium. The supply-constraints may originate in rational...

This paper studies the equilibrium dynamics of an overlapping generations model with capital, money and cash-in-advance constraints. At each date the economy can experience two different regimes. In the first one the cash-inadvance constraint is binding and money is a dominated asset. In the...

In this paper, we study the welfare effects of monetary policy in a simple overlapping generation economy in which agents voluntary contribute to a public good. Inflation has two effects at equilibrium: it increases voluntary contributions and it misallocates private consumption across time. We...

We first build a fair wage model in which effort varies over the business cycle. This mechanism decreases the need for other sources of sluggishness to explain the observed high inflation persistence. Second, we confront empirically our fairwage model with a New Keynesian model based on the...

In this paper, we consider the determinacy of equilibrium prices, interest rate and income in an economy with liquidity constraints and capital accumulation. In particular, we show that, even though no extrinsic uncertainty effects fundamentals, under some conditions, rational expectations...

In this paper the existence of unemployment is partly explained as being the result of coordination failures. This is achieved by considering a standard general equilibrium model and splitting the set of commodities in two groups. The first group contains commodities like gold. The prices of...
