This paper examines monetary and fiscal policy through the estimation of a New-Keynesian dynamic general equilibrium model for Iran’s economy. In this New-Keynesian dynamic general equilibrium model, the consumers encounter the liquidity constraint and the firms face sticky prices, while they are changing them. In the model presented, a role is considered for both government spending and taxati...

One interpretation of the RBC research program is that it was meant to identify and incorporate into dynamic general equilibrium models those market imperfections which are most relevant for macroeconomic theory and policy. This paper reviews the methodological basis for this interpretation. It then discusses the empirical foundations for some of the many frictions that have found their way int...

T he world economy has experienced a bulk of positive and negative shocks in crude oil prices and exchange rates over the years, and that global inflation has undergone some changes. Such shocks have affected the macroeconomic variables in the countries of the world and have challenged the economies of these countries, and have led them to take different measures to protect themselves agai...

We analyse a single sector economy with H > 1 infinitely-lived agents that operate in a continuous-time framework. Utility functions are recursive but not additive. Both efficient and perfect foresight competitive equilibrium allocations are considered. The existence and stability of such allocations are investigated locally, i.e., in a neighbourhood of steady-state allocations. The model is sh...

General discrete one-dimensional stochastic models to describe the transport of single molecules along coupled parallel lattices with period N are developed. Theoretical analysis that allows to calculate explicitly the steady-state dynamic properties of single molecules, such as mean velocity V and dispersion D, is presented for N=1 and N=2 models. For the systems with N>2 exact analytic expres...

This paper examines the two-fund separation paradigm in the context of an infinite-horizon general equilibrium model with dynamically complete markets and heterogeneous consumers with timeand state-separable utility functions. With the exception of the dynamic structure, we maintain the assumptions of the classical static models that exhibit two-fund separation with a riskless security. Agents ...

We introduce agent-based dynamics in a class of Arrow-Debreu economies with capital accumulation and technological progress. In this framework we confirm results obtained by [Gintis 2006] and [Gintis 2007] in an exchange economy: the micro-behavior of boundedly rational agents can lead to the emergence of equilibrium at the macro-level provided some form of collective optimization takes place v...

We construct a general equilibrium model with private information in which borrowers and lenders enter into long-term dynamic credit relationships. Each new generation of ex ante identical individuals is divided in equilibrium into workers and entrepreneurs. Workers save through financial intermediaries in the form of interest-bearing deposits and supply labor to entrepreneurs in a competitive ...

In this thesis, we study the problem of maximizing certain concave functionals on the space of optional random measures. Such functionals arise in microeconomic theory where their maximization corresponds to finding the optimal consumption plan of some economic agent. As an alternative to the well–known methods of Dynamic Programming, we develop a new approach which allows us to clarify the str...
