Effects of credit limit on efficiency and welfare in a simple general equilibrium model

We consider a simple general equilibrium model with two agents under the presence of financial market imperfections: agents can borrow to realize their productive project up to the level of debt whose repayment reaches a fraction of the project's value (so-called credit limit). After characterizing the whole set of equilibria, we investigate the connection between credit limit, (individual and social) welfare, and efficiency. We also compute the optimal credit limit which maximizes the social welfare function

Dividend taxation in an infinite-horizon general equilibrium model

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

Assets with possibly negative dividends

The paper introduces assets whose dividends can take any value (positive, negative or zero) in a dynamic general equilibrium model with financial market imperfections. We investigate the interplay between the asset markets and the production sector. The behavior of asset price and value is also studied

Credit limits and heterogeneity in general equilibrium models with a finite number of agents

We introduce two-period general equilibrium models with heterogeneous producers and financial frictions. Any agent can borrow to realize their productive project but the debt repayment does not exceed a fraction (so-called credit limit) of the project's value. Our framework allows us to investigate the aggregate and distributional effects of credit limits and heterogeneity of agents. The connection between credit limits, welfare, and efficiency is also explored

Intertemporal equilibrium with physical capital and financial asset: role of dividend taxation

The paper introduces dividend taxation and productive government spending in an infinite-horizon general equilibrium model with heterogeneous agents and financial market imperfections. We point out that imposing a dividend tax and using the revenue from this tax to finance productive government spending may prevent economic recession and promote economic growth. We also investigate the issue of optimal dividend taxation and the role of dividend taxation on the asset price bubble

Effects of foreign aid on the recipient country's economic growth

We introduce an infinite-horizon endogenous growth framework for studying the effects of foreign aid on the economic growth in a recipient country. Aid is used to partially finance the recipient's public investment. We point out that the same rule of aid may have very different outcomes, depending on the recipient's circumstances in terms of development level, domestic investment, efficiency in the use of aid and in public investment, etc. Foreign aid may promote growth in the recipient country, but the global dynamics of equilibrium are complex (because of the non-monotonicity and steady state multiplicity). The economy may converge to a steady state or grow without bounds. Moreover, there are rooms for the divergence and a two-period cycle. We characterize conditions under which each scenario takes place. Our analysis contributes to the debate on the nexus between aid and economic growth and in particular on the conditionality of aid effects

Sperner Lemma, Fixed Point Theorems, and the Existence of Equilibrium

In characterizing the existence of general equilibrium, existing studies mainly draw on Brouwer and Kakutani fixed point theorems and, to some extent, Gale-Nikaido-Debreu lemma. In this paper, we show that Sperner lemma can play a role as an alternative powerful tool for the same purpose. Specifically, Sperner lemma can be used to prove those theorems as well as the lemma. Additionally, Kakutani theorem is shown as a corollary of Gale-Nikaido-Debreu lemma. For a demonstration of the use of Sperner lemma to prove general equilibrium existence, we consider two competitive economies marked either by production goods or financial assets. In each case, we successfully provide another proof on the existence of a general equilibrium using only Sperner lemma and without a need to call on the fixed point theorems or the lemma
