This paper analyzes the impact of infrastructure investment on tax revenues and on the economy of the region. In 1991, the Kyushu high-speed rail line was constructed and was completed in 2003. In 2004, the rail line started operating from Kagoshima to Kumamoto. The entire line was opened in...

This paper analyzes the impact of infrastructure investment on tax revenues and on the regional economy by studying the effect of the Kyushu high-speed rail line (shinkansen train) in Japan. The effects of the Kyushu high-speed rail line on the economy has often been debated. We estimated its...

This paper discusses suggested ways to bring private sector finance into water supply and inland water transport. Typically, such water projects rely only on user charges as sources of revenues. For example, ships using inland waterways have to pay user charges to the government for port...

How much additional tax revenue can the government generate by increasing the level of labor income taxes? In this paper, we argue that the degree of tax progressivity is a quantitatively important determinant of the answer to this question. To make this point, we develop a large scale...

How much additional tax revenue can the government generate by increasing labor income taxes? In this paper we provide a quantitative answer to this question, and study the importance of the progressivity of the tax schedule for the ability of the government to generate tax revenues. We develop...

In this paper we argue that the degree of tax progressivity is a quantitatively important determinant of the answer to this question. To make this point we develop a large scale overlapping...

This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labour productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial...

In this paper we argue that very high marginal labor income tax rates are an effective tool for social insurance even when households have preferences with high labor supply elasticity, make dynamic savings decisions, and policies have general equilibrium effects. To make this point we construct...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...
