One of the plausible explanations for macroeconomic fluctuations relies on the occurrence of endogenous deterministic cycles. In the last three decades, most of the relevant literature has rested on the assumption of a representative agent but, recently, a few papers have investigated the role...

Macroeconomic dynamic models are often criticized because the households’ behavior is summarized by a representative agent and, then, they do not take into account consumers’ heterogeneity. Reconsidering the Woodford (1986) infinite-horizon model and the Reichlin (1986) OLG model, we show...

We consider an infinite horizon economy with representative agent, aggregate externalities on capital/labor ratio and liquidity constraint on income taxes. We show that the stationary rate of growth can be indeterminate for a wide range of elasticities of intertemporal substitution in...

In this paper, we consider a discrete time version of the endogenous growth model developed by Barro [1], but augmented in order to consider public production. Policy solutions are characterized to maximize the social welfare and stabilize the economy. More intervention is required under a...

Bubbles and money holding can reabsorb capital overaccumulation and restore the MGR in exogenous growth OLG economies. In contrast, under productive externalities and endogenous growth, bubbles and monetary saving can worsen an already inefficient underaccumulation. Under a simple credit market...

We study the implications of constant money growth rules on the stability properties of the equilibrium, in economies where agents are subject to a partial cash-in-advance constraint applying simultaneously to consumption and investment purchases. By reference to similar models in which the...

The model of endogenous fertility by Barro and Becker (1989) is augmented by taking into account the heterogeneity of households in terms of capital endowments, mortality, and costs per surviving child. There exists a unique balanced growth path where the population growth rates of all dynasties...

The international asset pricing models are mostly developed in the case of parity failure (investors of di?erent countries do not agree on the expected returns on securities). In this case, an equilibrium in the international asset markets may exist, but not in the international good markets. In...

A large literature has tried to find conditions such that expectations-driven fluctuations and endogenous cycles appear, but only few articles have focused on the role of consumers? heterogeneity. In our paper, we address this issue by considering an overlapping generations economy with...

In this model, we characterize optimal immigration and fiscal policies in presence of a rival public good and heterogeneous discounting. Surprisingly, even if the government is benevolent towards natives only, it is optimal to keep borders open. Indeed, in the long run, patient natives hold the...
