This paper describes a novel approach to both learning and computing Nash equilibrium in continuous games that is especially useful for analyzing structural game theoretic models of imperfect competition and oligopoly. We depart from the methods and assumptions of the traditional “Calculus” approach to computing equilibrium. Instead, we use a new and natural interpretation of games as condition...

B efore the incidence of the financial crisis in 2008, the financial sector was ignored in the most of business cycles analyses. It was assumed that the financial sector played no independent role in describing business cycle fluctuations and followed the real part of the economy. In recent years, modeling financial frictions have been much considered in business cycles literature. T...

I ran’s economy is suffering from sharp and persistent economic shocks and agriculture plays an undeniable role in its economic growth and development. The aim of this paper is to study the relative contributions of various macroeconomic shocks to generating fluctuations in Iran’s agriculture sector. To do so, a Dynamic Stochastic General Equilibrium (DSGE) model, emphasizing on the ...

In this paper we examine non-parametric restrictions on counterfactual analysis in a simple dynamic stochastic general equilibrium model. Under the assumption of timeseparable expected utility and complete markets all equilibria in this model are stationary, the Arrow-Debreu prices uniquely reveal the probabilities and discount factor and the equilibrium correspondence defined as the map from e...

We prove existence of time consistent equilibria in a class dynamic models with recursive payoffs and generalized discounting involving both behavioral normative applications. Our Bellman equation method identifies separates both: strategic aspects the equilibrium problem allows to determine sufficient assumptions on preferences stochastic transition establish existence. In particular we show m...

We use mixed-frequency (quarterly-monthly) data to estimate a dynamic stochastic general equilibrium model embedded with the financial accelerator mechanism à la Bernanke et al. (1999). find that can work very differently at monthly frequency compared quarterly frequency; is, we document its inversion. That is because aggregating into leads large biases in estimated parameters and, as consequen...

The authors consider the fundamental problem of nding good policies in uncertain models. It is demonstrated that although the general problem of nding the best policy with respect to the worst model is NP-hard, in the special case of a convex uncertainty set the problem is tractable. A stochastic dynamic game is proposed, and the security equilibrium solution of the game is shown to correspond ...
