In interim economies with asymmetric information, we show that the coarse core of Wilson (1978) does not converge to price equilibrium allocations as the economy is replicated. This failure of core convergence is a basic consequence of asymmetric information and extends to any reasonable notion of either (interim) core or price equilibrium. JEL Classification: C71, D51

In an economy with commodity-pairwise trading posts and transaction costs, commodity money is endogenously determined in general equilibrium. Absent double coincidence of wants, the lowtransaction cost commodity (with the narrowest proportional bid/ask price spread) becomes the common medium of exchange. JEL Classification: C62, E40

Aiyagari (1992) shows that equilibria are nonoptimal for an overlapping generations economy if and only if Walras’ Law fails. We demonstrate that this failure represents an earnings opportunity exploitable by unsecured debt issue. When unsecured debt is issued, Walras’ Law holds. JEL Classification: D5, D6, D9

The purpose of this paper is to give a global characterization of excess demand functions in a two period exchange economy with incomplete real asset markets. We show that continuity, homogeneity and Walras’ law characterize the aggregate excess demand functions on any compact price set which maintains the dimension of the budget set. JEL classification: D52, C62.

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 prove the existence of a private value allocation for an economy with differential information where the commodity space may be infinite dimensional, and there is a continuum of states. We also discuss the existence, non-existence, and properties of two alternative value allocation concepts. JEL classification: D8; D82; C7; C71; C72

unemployment-inflation trade-off is known as philips curve. this relationship was first defined for england economy by professor philips since 1958. much development has been submitted by different economic schools about this innovation. in this paper, apart from dealing with the new-keynesians philips curve, the curve mentioned is estimated for iranian economy. in addition, we are going to com...

This study reports a simple experiment using induced-value items to assess the accuracy of the Becker, DeGroot, Marschak (BDM) method (1964 Behavioral Science) for measuring preferences. Although the BDM mechanism is incentive compatible the data indicate that it can be empirically unreliable due to susceptibility to subject misconceptions about the game form. The resulting choices appear to re...

Stress in financial markets influences economic agents’ behavior by creating uncertainty and changing the expectations. Critical financial stress can lead to financial crisis. Financial crises are among the events always present in the world economy. Iran is not an exception. This paper aims to study the impact of financial stresses on Iran’s per capita GDP. By using ARDL (Auto Regressive Distr...
