This paper presents a simple model that displays a joint determination of income inequality and intergenerational mobility affected by redistributive taxation. The model shows that a larger redistribution improves equality and utility and enhances mobility when the poor are financially...

This paper focuses on how education costs affect the political determination of redistribution policy via individual decision making on education. For cases of high costs, there are multiple equilibria: the poor-majority equilibrium featured by the minority of highly educated individuals and a...

This paper analyzes a social security policy with public debt in an overlapping generations growth model. In particular, the paper considers a situation in which population aging causes a heavy burden of social security payments where public debt is issued by the government to finance the...

There have been opposing conclusions in the literature as to whether lender liability increases the probability of environmentally harmful accidents. This paper shows that s multiplicity of equilibria is the key to solve such contradictory conclusions.

We develop an overlapping generations model of growth and the environment in which industrial firms produce environmentally harmful emissions. A government controls the emissions by assigning emission quotas to firms, and permits could be issued and freely traded as financial instruments across...

In this paper, we analyze the effects of population aging on economic growth and the environment in a two-period overlapping generations model of growth, aging, and the environment. We show that aging may be beneficial to economic growth and the environment under perfect annuitisation, while...

This paper develops a two-period overlapping-generations model with environmental externalities and uncertain lifetimes, and studies how two sources of population aging, greater longevity and a lower rate of population growth, affect the politically determined environmental tax and the quality...

This paper focuses on how education costs affect the political determination of public policy via individual decision-making. The paper extends the model in Hassler, Storesletten, and Zilibotti (2007, Journal of Economic Theory; henceforth HSZ) by generalizing the cost function of education and...

This paper focuses on how education costs affect the political determination of redistribution policy via individual decision-making on education. For cases of high costs, there are multiple equilibria: the high-tax equilibrium featured by the minority of highly educated individuals and a large...
