The standard tax theory result that investment should not be distorted is based on the assumption that profits are locally bound. In this paper we analyze the optimal tax policy when firms are internationally mobile. We show that the optimal policy response to increasing firm mobility may be...

This paper accounts for China.s economic growth since 1980 in a unified endogenous growth model in which a sequencing of physical capital accumulation, human capital ac-cumulation and innovation drives the rise in China.s aggregate income. The first stage is characterized by physical capital...

We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria.

In this paper we compute the optimal tax and education policy transition in an economy where progressive taxes provide social insurance against idiosyncratic wage risk, but distort the education decision of households. Optimally chosen tertiary education subsidies mitigate these distortions. We...

Amid global climate change concerns, policymakers worldwide are increasingly scrutinizing environmentally harmful subsidies. This study examines the tax-deductibility of job-related commuting expenses, which has faced criticism for promoting longer commutes and congestion. Through a controlled,...

This paper considers a three-overlapping-generations model of endogenous growth wherein human capital is the engine of growth. It first contrasts the laissez-faire and the optimal solutions. Three possible accumulation regimes are distinguished. Then it discusses a standard set of tax-transfer...

We study the dynamic Ramsey problem of finding optimal public debt and linear taxes on capital and labor income within a tractable infinite horizon model with incomplete markets. With zero public expenditure and debt, it is optimal to tax the risky labor income and subsidize capital, while a...

We consider an economy where individuals face uninsurable risks to their human capital accumulation and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

We investigate the misuse of R&D subsidies and evaluate its consequences for policy effectiveness. Developing a theoretical framework and using Chinese firm-level data for 2001-2011, we identify that 42% of grantees misappropriated R&D subsidies for non-R&D purposes, accounting for 53% of total...
