this paper extends endogenous growth models through augmenting it with government budget and oil revenues as well as the effect of public investment efficiency on long run growth of private and government consumption and import for an oil producing economy. based on the extracted model, the optimal growth rate of government current expenditure (or consumption) has a positive relation with the e...

This note provides a new proof of the non–emptiness of the fuzzy core in a pure exchange economy with finitely many agents. The proof is based on the concept of (Π, β)–balanced core for games without side payments due to Bonnisseau and Iehlé (2003). JEL classification codes: D51, C71.

In the aftermath of the global financial crisis questions have been raised regarding the value and applicability of modern macroeconomics. Motivated by these developments and recent advances in dynamical systems theory, the papers in this special issue of Macroeconomic Dynamics deal with specific aspects of the economy as a complex evolving dynamic system. JEL classification: A1, B4, E1, G01.

Awareness and AIDS: A Political Economy Perspective* Across African countries, prevention policies are unrelated to the prevalence of HIV/AIDS and, even in countries in which they were successful, these policies are often unstable or reversed. To explain these two puzzles, we propose a simple political economy model that examines how prevention policies and the epidemic dynamics are jointly det...

The ‘noise trader’ model of De Long et al. provides a plausible account of the determination of the equity premium. Extension of the model to allow for privatization of publicly-owned assets yields insights into the positive political economy of privatization and into the normative question of how policies should be evaluated in the presence of mistaken beliefs.

This paper shows equilibrium existence for an infinite–horizon exchange economy with incomplete markets of real assets when default is allowed. Borrowers are required to constitute collateral in terms of durable goods and face credit constraints that depend on their past default. When credit constraints are inelastic, Ponzi schemes are ruled out and an equilibrium exists. JEL Classification: D5...

this paper presents a new index of financial stress which is constructed by macro data from different financial markets (including banking sector and also housing, foreign exchange and stock markets). the proposed approach has been applied to the iranian economy based on the available quarterly time series, covering the period 1991(1)–2008(2). the paper explains how the selected components capt...

This paper is a reply to Barry Ickes' critique of my paper “Trust versus Illusion: What is Driving Demonetization in Russia?” in which I show that the data reject Barry Ickes' Virtual Economy explanation of barter in Russia in favor of an institutional explanation based on the lack of trust.

We study the wealth distribution in Bewley economies with idiosyncratic capital income risk. We show analytically that under rather general conditions on the stochastic structure of the economy, a unique ergodic distribution of wealth displays a fat tail. © 2015 Elsevier Inc.

In the jungle, power and coercion govern the exchange of resources. We study a simple, stylized model of the jungle that mirrors an exchange economy. We define the notion of jungle equilibrium and demonstrate that a number of standard results of competitive markets hold in the jungle. JEL Classification: C7, D4, S477, B201
