We examine the effects of environmental policies such as a subsidy for reforestation and an export-income tax in a small open economy with a renewable resource. In the small economy, the harvested renewable resources are exported to acquire foreign assets and consumers can invest in the natural...

Using a simple overlapping generations model, this note shows that an improvement in the efficiency of human capital investment decreases the net income of the young household while increasing that of the old. Without compensating redistribution, it deteriorates lifetime utilities of all...

We construct an endogenous growth model with productive public capital and government debt when government debt is adjusted to the target level. We examine how reducing public debt in an economy with a large public debt affects the transition of the economy and welfare. We find that the...

We construct a small open economy model of endogenous growth with public capital accumulation and examine how a debt policy rule under which the government gradually reduces its debt-GDP ratio to a target level affects macroeconomic stability, fiscal sustainability, and welfare. We obtain the...

In this paper, we investigate how strengthening patent protection affects economic growth in an endogenous growth model where both innovation and capital accumulation are the driving forces of economic growth. In this model, stronger patent protection raises the profit flow obtained by...

We study the relationship between commodity taxation and the effect of entry with imperfect competition. We develop a simple general equilibrium model with imperfect competition in which consumers have variety preferences. As a result, we see that introducing specific taxes increases social...
