The aim of this paper is to study the role of progressive tax rules on the allocations of steady state and the stability properties in a Ramsey economy with heterogeneous households and borrowing constraints. Since labor supply in elastic, considering different tax rates on capital and labor...

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...

Un grand nombre de travaux ont cherché à exhiber les conditions sous lesquelles des fluctuations dues à la volatilité des anticipations des agents et des cycles endogènes apparaissent, mais peu d'entre eux sesont intéressés au rôle de l'hétérogénéité des consommateurs. Dans cet...

We analyze the stabilizing role of imperfect competition on fluctuations due to indeterminacy and endogenous cycles. In this paper, imperfect competition is a source of monopoly profits, because of producer market power. Considering anoverlapping generations model with capital accumulation and...

We consider an overlapping generations model with environment and an elastic labor supply. In this framework, consumers have to choose between consumption, environmental quality, and leisure. We show the existence of both deterministic cycles and indeterminacy. In contrast to previous results,...

In macroeconomics, economists introduce most frequently imperfect competition on product markets using the Dixit and Stiglitz (1977) monopolistic competition model. However, by assumption, this framework ignores one important feature of imperfect competition: strategic interactions between...

We study the influence of wage differential on the emergence of endogenous fluctuations. In this way, we introduce a dual labor market, based on the Shapiro-Stiglitz efficiency wage theory in an overlapping generations model. We show that wage inequality is a source of endogenous fluctuations....

While most of the literature concerned with indeterminacy and endogenous cycles is based on the restrictive assumption of a representative consumer,some recent contributions have investigated the role of heterogeneous agents in dynamics. This paper adds to this latter strand of the literature by...

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...

In past years, imperfect competition has been introduced in several dynamic models to show how mark-up variability, increasing returns (decreasing marginal cost), and monopoly profits affect the occurrence of endogenous fluctuations. In this paper, we focus on another possible feature of...
