We offer a qualitative evaluation of the transmission mechanisms of two real shocks, a productivity shock and a government expenditure shock in Walrasian business cycle models. The analysis is developed in a monetary small open economy business cycle model, a set-up general enough to study the...

We are interested in the occurrence of expectation-driven fluctuations of a rational bubble and the (de-)stabilizing role of monetary policy. Our explanation of fluctuations is based on credit market imperfections. For this purpose, we consider an overlapping generations exchange economy where...

We explore the existence of endogenous fluctuations with a rational bubble and the stabilizing role of fiscal and monetary policies. Consumers' credit constraints, the role of collateral and a portfolio choice are the key ingredients of our analysis. We consider an overlapping generations model...

In this paper, we study the equilibrium dynamics of an overlapping generations model with capital, money and cash-in-advance constraints. At each period, the economy can experience two different regimes: either the cash-inadvance constraint is binding and money is a dominated asset, or the...

Motivated by the substantial increase of nominal money supply in the U.S. economy since late 2008, this paper examines the equilibrium growth effect of money/inflation within a standard one-sector AK model of endogenous growth with wealth-enhanced preferences for social status and the most...

This paper examines the consequences of introducing a cash-in-advance constraint in a small open economy business cycle model for the Spanish economy. A business cycle model is built extending Correia, Neves and Rebelo (1995) small open economy framework and Cooley and Hansen (1995) monetary...

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...

This paper is a study of money in overlapping generations models with cash-in-advance constraints. We first offer a brief review of different features of the cash-in-advance constraint. Then we propose a general formulation and study the neutrality of money. We show that both neutrality and...

In his seminal contribution, Tirole (1985) shows that an overlapping generations economy may monotonically converges to a steady state with a positive rational bubble, characterized by the dynamically efficient golden rule. The issue we address is whether this monotonic convergence to an...

This paper examines the long-run impact of inflation tax in the context of a generalized Ak growth model in which the production technology uses two types of capital stocks under a constant-returns-to-scale technology. We find hat unless investment expenditure for each type of capital is subject...
