We prove that a two-cycle equilibrium in a general equilibrium model with infinitely-lived agents also constitutes an equilibrium in an overlapping generations (OLG) model. Conversely, an equilibrium in an OLG model that satisfies additional conditions is part of an equilibrium in a general...

In a market economy, the aggregate production level depends not only on the aggregate variables but also on the distribution of individual characteristics (e.g., productivity, credit limit, .). We point out that, due to financial frictions, the equilibrium aggregate production may be...

In this paper we use only Sperner’s lemma to prove the existence of general equilibrium for a competitive economy with production or with uncertainty and financial assets. We show that the direct use of Sperner’s lemma together with Carathéodory’s convexity theorem and basic properties of...

We show that both real indeterminacy and asset price bubble may appear in an infinite-horizon exchange economy with infinitely lived agents and an imperfect financial market. We clarify how the asset structure and heterogeneity (in terms of preferences and endowments) affect the existence and...

Productivity is a key concept in economics and crucial for economic growth. By using different theoretical models, we show the role of several kinds of productivity, including total factor productivity (TFP) and labor productivity.

The paper investigates the country receiving FDI's optimal strategy in an optimal growth context. First, if the multinational enterprise has high productivity or the entry cost is high, no domestic firm enters the new industry. Still, the host economy's investment stock converges to a higher...

We consider an infinite-horizon general equilibrium model with heterogeneous agents and financial market imperfections. We investigate the role of dividend taxation on economic growth and asset price. The optimal dividend taxation is also studied.

We consider an overlapping generations economy with altruism towards parents and a long-lived asset that delivers no dividends (pure bubble asset). We explore the role of ascendant altruism on the dynamics properties of equilibrium and rational bubbles in the cases of exogenous and endogenous...

We consider an overlapping generations model à la Diamond (1965) with two additional ingredients: altruism and an asset (or land) bringing non-stationary positive dividends (or fruits). We study the global dynamics of capital stocks and asset values as well as the interplay between them. Asset...

We build a dynamic general equilibrium model with heterogeneous producers and financial frictions (collateral constraints and incompleteness). First, we provide a characterization to check whether a sequence is an equilibrium or not. Second, we study the effects of financial imperfections on...
