This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...

Does Manager Turnover Improve Firm Performance? New Evidence Using Information from Dutch Soccer, 1986-2004 This research examines the impact of manager turnover on firm performance using information from the Dutch soccer league in the period 1986-2004. The advantage of using sports data is that both manager characteristics and decisions and firm outcomes are directly observable. Both differenc...

we describe a simple model that fits well with iranian economy, and extends a methodology which chary at el. (2007) demonstrated. in addition to four traditional wedges, we introduce additional trade wedge. we then evaluate the contribution of these wedges to the fluctuations in iran during last three years. because of international sanction, trading cost increases, and firms have difficulty to...

Rational expectations solutions are usually derived by assuming that all state variables relevant to forward-looking behaviour are directly observable, or that they are "...an invertible function of observables" (Mehra and Prescott, 1980). Using a framework that nests linearised DSGE models, we give a number of results useful for the analysis of linear rational expectations models with restrict...

We explore the connection between shock observability and equilibrium. When aggregate shocks are unobserved the rational expectations solutions remain unchanged if contemporaneous aggregate outcomes are observable, but their stability under adaptive learning must be reconsidered. We obtain learning stability conditions and show that, provided there is not large positive expectational feedback, ...

this study is an attempt to develop a model of the simultaneous structure of the aggregate dynamic supply and demand to be used for estimation of parameters from data related to iran’s economy. the method for developing the model is an application of the dynamic and simultaneous process of aggregate supply and demand. obtained differential equations are used for solve the model. to estimate the...

In this paper, I find that real U.S. GDP is better characterized as a trend stationary Markov-switching process than as having a (regime-dependent) unit root. I examine the effects of both assumptions on the analysis of business cycle features and their implications for the persistence of the dynamic response of output to a random disturbance.

We estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on United Kingdom data. Our estimates suggest that price stickiness is a more important source of nominal rigidity in the U.K. than wage stickiness. Our estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects govern...

This paper provides a dynamic optimization model of durable good inventories to study the interactions between investment demand and production of capital goods. There are three major findings: First, capital suppliers’ inventory behavior makes investment demand more volatile in equilibrium; Second, equilibrium price of capital is characterized by downward stickiness; Third, the responses of th...
