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...

While most of the literature concerned with indeterminacy considers a representative agent, some recent works have investigated the role of heterogenous agents on dynamics. This paper adds a contribution to the debate, stressing the effects of heterogeneity in consumers’ preferences within an...

We consider a general equilibrium model with heterogeneous agents, borrowing constraints, and exogenous labor supply. First, the existence of intertemporal equilibrium is proved even if the aggregate capitals are not uniformly bounded above and the production functions are not time invariant....

In this paper, we study the effects of collaterals on business cycles and growth in monetary economies with credit market imperfections. We consider an endogenous growth model with a partial cash-in-advance constraint and inelastic labor supply. We assume that the share of consumption purchases...

This paper aims at providing a simple economic framework to address a somewhat neglected question of economic policy, namely the optimal share of investments in medical R&D in total public spending. In or- der to capture the long-run impact of tax-financed medical R&D on the growth rate, we...
