General equilibrium, wariness and efficient bubbles
2011-05Wary consumers overlook gains but not losses in remote sets of dates or states. As preferences are upper but not lower Mackey semi-continuous, Bewley's (1972) [4] result on existence of equilibrium whose prices are not ... -
The general existence of extended price equilibria with infinitely many commodities
1994-08This paper deals with the existence of equilibria with infinitely many goods. Its main goal is to show that when restricted to the set of feasible allocations there exists an economically meaningful price (in the sense ... -
Health Care Reform or More Affordable Health Care?
2016-06-17This article investigates the impact on the U.S. economy of making health care more affordable. We compare health care cost reductions with the Patient Protection and Affordable Care Act (PPACA) using a rich life cycle ... -

2020-10-21A energia hidráulica sempre teve um papel importante na matriz elétrica brasileira e seus custos de geração representam uma parcela significativa do valor pago pelo consumidor final. Fatores tecnológicos, ambientais, ... -

Inadimplência de dívida soberana em modelo de equilíbrio geral com credores heterogêneos
2012-09-19This paper provides a general equilibrium model of sovereign default with agents' heterogeneity, but without banking or foreign sectors. The heterogeneity is due to different kinds of consumers in the economy with distinct ... -
Incomplete markets, continuum of states and default
1998-01We show that when bankruptcy, subject to penalties, is allowed, it is possible to prove the existence of equilibrium in a model with a continuum of states without imposing any assumptions on ex-post endowments. -
Inconsequential arbitrage
2000-12We introduce the concept of inconsequential arbitrage and, in the context of a model allowing short-sales and half-lines in indifference surfaces, prove that inconsequential arbitrage is sufficient for existence of ... -
Increasing cones, recession cones and global cones
2000In this paper, we discuss and compare various cones used in the economics literature to analyze arbitrage in general equilibrium models with short selling. Our main result is that under certain conditions on an economic ... -
Information asymmetry and debt sustainability
2019-04-24Bulow and Rogoff (1989) proved that, in a competitive financial market, the threat of credit exclusion alone cannot sustain repayment of sovereign debt, as the defaulting government can still enter cash-in-advance insurance ... -
Investment-specific technological change and the Brazilian macroeconomy
2015-03-03This study discusses the importance of investment-specific technological change for the brazilian macroeconomy. We document evidence that a model that takes this specific type of technical progress into account is better ... -
Large economies with differential information and without free disposal
2009-02We consider exchange economies with a continuum of agents and differential information about finitely many states of nature. It was proved in Einy et al. (Econ Theory 18, 321-332, 2001) that if we allow for free disposal ... -
The Limits of political compromise: debt ceilings and political competition
2015We study the desirability of limits on the public debt and of political competition in an economy where political parties alternate in office. Due to rent-seeking motives, incumbents have an incentive to set public ... -
Local concavifiability of preferences and determinacy of equilibrium
1991-05In this paper we consider strictly convex monotone continuous complete preorderings on R+n that are locally representable by a concave utility function. By Alexandroff 's (1939) theorem, this function is twice dífferentiable ... -
Long-lived collateralized assets and bubbles
2011-05When infinite-lived agents trade long-lived assets secured by durable goods, equilibrium exists without any additional debt constraints or uniform impatience conditions on agents' characteristics. Also, price bubbles are ... -
Modelos de equilíbrio geral dinâmico com custo de default
2013-06-20This work consists on a survey of some papers from the literature of general equilibrium with default costs. We focus on the study of Kehoe and Levine (1993) and Alvarez and Jermann (2000) models. We also describe some ...
