in this research, the attempt was made to test the existence of the natural rate hypothesis in iran, by using a johansson cointegration test. the results do not reveal any long run relationship between inflation and unemployment in iran for 1340-1386 periods. because of the time varying nature of nairu, the hp filter was applied to estimate the time series of nairu. comparing the nairu time ser...

This paper analyses the role of political connections in the post-entry performance of private start-up companies in China. It documents robust evidence that political affiliation enhances firms’ survival and growth prospects, even if politically neutral start-ups enjoy faster productivity improvements. In addition, the benefits of political connections are largely confined to firms associated ...

We add inside and outside money to the standard GEI model. If there enough gains to trade via money, then monetary equilibrium (ME) exists and money has positive value, even when GEI fails to exist. The nonexistence of GEI shows up as a liquidity trap in terms of the ME. In sharp contrast to GEI, the ME are generically determinate not only in terms of real, but also financial, variables. © 2003...

Aid, Growth, and Jobs Various development objectives are worthy, but to my mind, one objective dominates all others: reducing the scourge of absolute economic misery in the world. In this paper, I focus on an important but relatively underemphasized approach to poverty reduction: helping the poor earn more in the labour market for the work they do, so that they can buy the goods and services th...

This paper examines how robust economic, political, and demographic variables are related to water and air pollution. Employing Bayesian Averaging of Classical Estimates (BACE) for a cross section of up to 74 countries, 33 variables and 3 proxies for air and water pollution over a period from 1980 to 1995 we confirm the Environmental Kuznets Curve hypothesis, highlight the relevance of efficien...

This paper investigates currency and financial crises in an optimizing general equilibrium model. It is shown that a rise in current and expected future budget deficits generates a real exchange rate appreciation and a decumulation of external assets, leading up to a currency crisis when foreign reserves approximate a critical level. Strong empirical support for our model is obtained by a probi...

This paper models interaction between groups of agents by means of a graph where each node represents a group of agents and an arc represents bilateral interaction. It departs from the standard KatzShapiro framework by assuming that network benefits are restricted only amongst groups of linked agents. It shows that even if rival firms engage in Bertrand competition, this form of network externa...

The aim of this paper is to analyse whether legal rules, set up during the first years of the economic transition, could stimulate behaviour of economic subjects so that it would lead to desired results in macroeconomic benchmarks. This problem is solved using a case of joint-stock companies management (i.e. both ways and possibilities of their administration) in the Czech Republic during the 1...
