iranian banks can not freely determine their interest rates in the financial market. this characteristic causes banking industry unable to perform their duties of financial intermediaries in the transmission mechanism of monetary. in these circumstances, monetary shocks will have a significant and high effect on the alternative markets (like stocks and housing). in this study, we used dynamic s...

Tax rates have fluctuated considerably since federal income taxes were introduced in the U.S. in 1913. This paper analyzes the effects of stochastic taxation on asset prices in a dynamic general equilibrium model. Stochastic taxation affects the after-tax returns of both risky and safe assets. Whenever taxes change, bond and equity prices adjust to clear the asset markets. These price adjustmen...

Together with a sense of entering a New Economy, the US experienced in the second half of the 1990s an economic expansion, a stock market boom, a financing boom for new firms and productivity gains. In this paper, we propose an interpretation of these events within a general equilibrium model with financial frictions and decreasing returns to scale in production. We show that the mere prospect ...

I develop a quantitative, dynamic general equilibrium model of life cycle behavior to study the effects of several policy reforms on assets composition over the life cycle, wealth distribution and aggregate saving. Privatizing social security increases aggregate saving, decreases overall wealth inequality, and generates large welfare gain, especially for agents with high initial productivity. L...

This paper derives the dynamic programming equation (DPE) to a differentiable Markov Perfect equilibrium in a problem with non-constant discounting and general functional forms. Beginning with a discrete stage model and taking the limit as the length of the stage goes to 0 leads to the DPE corresponding to the continuous time problem. The note discusses the multiplicity of equilibria under non-...

The welfare cost of imperfect competition in the product and labor markets in the United States is quantified in a dynamic general equilibrium model. We find that the welfare cost of imperfect competition in the product market is 3.62 percent while it is 0.58 percent in the labor market, taking the transition path from the distorted to the optimal steady state into account. If we also take into...

We study asset-pricing implications of innovation in a general-equilibrium overlappinggenerations economy. Innovation increases the competitive pressure on existing firms and workers, reducing the profits of existing firms and eroding the human capital of older workers. Due to the lack of inter-generational risk sharing, innovation creates a systematic risk factor, which we call “displacement r...

The framework of a general equilibrium heterogeneous agent model is used to study the optimal design of an unemployment insurance (UI) scheme and preferences for unemployment policy reforms. In a first step, the optimal defined benefit and defined replacement ratio UI systems are obtained in simulations. Then, the question whether switching to such an optimal system from the status quo would be...

Micro data over the life cycle shows different patterns of consumption for housing and non-housing goods: the consumption profile of non-housing goods is hump-shaped while the consumption profile for housing first increases monotonically and then flattens out. These patterns hold true at each consumption quartile. This paper develops a quantitative, dynamic general equilibrium model of life-cyc...

A general equilibrium model of a small open economy is developed to analyze the optimal rate of inflation under discretion. Once agents’ welfare is the sole policy objective it is possible to show that openness and inflation no longer have a simple inverse relationship. A greater degree of openness may lead the policy maker to want to exploit the short-run Phillips curve more aggressively, even...
