In this paper, we address the question of deterministic cycles in a Ramsey model with heterogeneous infinite-lived agents and borrowing constraints, augmented to take into account the case of elastic labor supply. Under usual restrictions, not only we show that the steady state is unique, but...

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...

We study the existence of equilibrium and rational bubbles in a Ramsey model with heterogeneous agents, borrowing constraints and endogenous labor. Applying a Kakutani's fixed-point theorem, we prove the existence of equilibrium in a time-truncated bounded economy. A common argument shows this...

In his seminal contribution, Tirole (1985) shows that an overlapping generations economy may monotonically converge 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...

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

In this paper, we address the stability issue, stressing the role of labor supply, in a Ramsey model with heterogeneous households subject to borrowing constraints. Making labor supply endogenous leads us to prove the existence of two kinds of steady state: the one where everybody supplies...

Cet article propose de présenter dans un cadre simple, mais unifié, un certain nombre de résultats liés à l'existence et aux fluctuations d'une bulle rationnelle. Nous développons une économie d'échange à générations imbriquées dans laquelle chaque ménage fait un choix de...

We address the fundamental issues of existence and efficiency of a Ramsey equilibrium with heterogenous discounting, elastic labor supply and borrowing constraints. In the first part, we prove the equilibrium existence in a truncated bounded economy through a fixed-point argument by Gale and...
