In this paper we explore the proposition that in economies with imperfect competitive markets the optimal capital income tax is negative and the optimal tax on firms profits is confiscatory. We show that if the total factor productivity as well as the measure of firms or varieties are endogenous...

We examine the optimal policy response to an exogenously given demographic shock. Such a shock affects negatively the financing of retirement pensions, and we use optimal fiscal policy in order to determine the optimal strategy of the social security administration. Our approach provides...

The last decade has brought about substantial mortgage innovation and increased refinancing. The objective of the paper is to understand the determinants and implications of mortgage choice in the context of general equilibrium model with incomplete markets. The equilibrium characterization...

This paper analyzes the connection between the asymmetric tax treatment of homeowners and landlords and the progressivity of income taxation using a quantitative overlapping generations general equilibrium model with housing and rental markets. Our model emphasizes the determinants of tenure...

The objective of this paper is to understand how loan structure affects (i) the borrower's selection of a mortgage contract and (ii) the aggregate economy. We develop a quantitative equilibrium theory of mortgage choice where households can choose from a menu of long-term (nominal) mortgage...

After the collapse of housing markets during the Great Depression, the U.S. government played a large role in shaping the future of housing finance and policy. Soon thereafter, housing markets witnessed the largest boom in recent history. The objective in this paper is to quantify the...

This paper analyzes the effectiveness of three different types of education policies: tuition subsidies (broad based, merit based, and flat tuition), grant subsidies (broad based and merit based), and loan limit restrictions. We develop a quantitative theory of college within the context of...

This paper explores the role played by structural transformation and the resulting relocation of workers from rural to urban areas in the recent housing boom in China. This development process has fostered an ongoing increase in urban housing demand, which, combined with a relatively inelastic...

This paper uses a overlapping generation general equilibrium model to study a reform of the social security system, going from an unfunded to a funded system. We also analyze the effects of this reform on the incentives of young generations to acquire skills. the main objective is to evaluate...

We examine the optimal policy response to an exogenously given demographic shock. Such a shock affects negatively the financing of retirement pensions, and we use optimal fiscal policy in order to determine the optimal strategy of the social security administration. Our approach provides...
