Free entry equilibria are usually determined by resorting to the zero profit condition. We plead instead for a strict application of the Nash equilibrium concept to a symmetric one-stage game played by actual and potential producers, who have a decreasing average cost function without sunk costs. Equilibrium then appears as typically indeterminate, with a number of active firms varying between ...

The relation between macroeconomic fundamentals and the cross section of asset returns is studied through the lens of dynamic stochastic general equilibrium (DSGE) models. We provide a full-information Bayesian estimation of the model using seven macroeconomic variables and extract the time series of three fundamental shocks to the economy for the period of 1966Q1-2010Q3: neutral technology (NT...

Should a central bank accommodate energy price shocks? Should the central bank use core inflation or headline inflation with the volatile energy component in its Taylor rule? To answer these questions, we build a dynamic stochastic general equilibrium model with energy use, durable goods, and nominal rigidities to study the effects of an energy price shock and its impact on the macroeconomy whe...

Oil price shocks are the main source of macroeconomic fluctuations in oil exporting countries. It is believed that appropriate monetary policy can help to stabilize these unwanted variations toward optimal allocations. A stochastic dynamic general equilibrium model featuring the properties of both cost push and wealth effect transmission channels is developed for the Iranian economy. In thi...

We introduce the concept of a Misspecification Equilibrium to dynamic macroeconomics. A Misspecification Equilibrium occurs in a stochastic process when agents forecast optimally given that they must choose from a list of misspecified econometric models. With appropriate restrictions on the asymptotic properties of the exogeneous process and on the feedback of expectations, the Misspecification...
