Identifiability of Dynamic Stochastic General Equilibrium Models with Covariance Restrictions
نویسندگان
چکیده مقاله:
This article is concerned with identification problem of parameters of Dynamic Stochastic General Equilibrium Models with emphasis on structural constraints, so that the number of observable variables is equal to the number of exogenous variables. We derived a set of identifiability conditions and suggested a procedure for a thorough analysis of identification at each point in the parameters space. The procedure can be applied, before DSGE models are estimated, to determine where identification fails, and where it likely to be weak. We also used a Monte Carlo simulation and studied the effect of restrictions on the estimate. The results show that the use of restrictions for estimation, when identification is reduced, leads us to inaccurate estimates and unreliable inference even when the number of observations is large

Dynamic Stochastic General-equilibrium Models of Fluctuations
Our analysis of macroeconomic fluctuations in the previous two chapters has developed two very incomplete pieces. In Chapter 5, we considered a full intertemporal macroeconomic model built from microeconomic foundations with explicit assumptions about the behavior of the underlying shocks. The model generated quantitative predictions about fluctuations, and is therefore an example of a quantita...
متن کاملSolving Dynamic Stochastic Competitive General Equilibrium Models
The Scarf algorithm was the Þrst practical, almost surely convergent method for computing general equilibria of competitive models. The current focus of much computational research is computing equilibrium of dynamic stochastic models. While many of these models are examples of Arrow-Debreu equilibria, Scarfs algorithm and subsequent homotopy methods cannot be applied directly since they have ...
متن کاملDynamic Labor Market in a Dynamic Stochastic General Equilibrium Model: Case Study of Iranian Economy
The labor market, as one of the four markets, plays an important role in economic growth and development. So review developments in the labor market because of its close relationship with developments in other sectors is of great importance. This study tries to examine the dynamics of the labor market by adjusting for a New Keynesian dynamic stochastic general equilibrium model for the Iranian ...
متن کاملEconometric analysis of linearized singular dynamic stochastic general equilibrium models
In this paper I propose an alternative to calibration of linearized singular dynamic stochastic general equilibrium models. Given an a-theoretical econometric model as a representative of the data generating process, I will construct an information measure which compares the conditional distribution of the econometric model variables with the corresponding singular conditional distribution of t...
متن کاملImplementation of VAT on Iran banking services in the context of dynamic stochastic general equilibrium model
In the Value Added Tax (VAT) system some goods and services, such as banking services, are exempted from taxes. Based on theoretical foundations, exempt treatment leads to several distortions and inefficiencies in the economy. In order to understand the importance of exemption on macroeconomic fluctuations as well as the fundamental role of financial intermediaries in economy shocks, this study...
متن کاملThe Impact of Monetary and Exchange Policies on the Country’s Trade balance Fluctuation with the Approach of Dynamic Stochastic General Equilibrium (DSGE) models
This paper uses the framework of new Keynesian school and the literature of the Dynamic Stochastic General Equilibrium (DSGE) model to build a general model that can be estimated for Iran economy. By simulating this model, the effects of the implementation of monetary and foreign exchange policies through policy instruments including bank interest rate, central bank international reserves and t...
