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...

This paper examines the welfare-maximizing degree of patent protection in a growth model where the engines of economic growth are R&D and public services. The result shows that if public services are small, the welfare-maximizing level of patent protection is weaker.

We construct an endogenous growth model with productive public capital and government debt, in which government debt is gradually adjusted to the target level. We examine how the governmentfs debt reductions affect the transitional dynamics and welfare of the economy. We show that fiscal...

We construct an endogenous growth model with productive public capital and government debts where government debts are gradually adjusted to target level. We examine how debt-reductions of the government affect the transitional dynamics and welfare of the economy. Fiscal consolidation has...

This paper investigates the transitional dynamics of a basic Schumpeterian growth model under constant relative risk aversion. In this model, there are three patterns of the evolution of wage inequality: (a) skill-biased technological change, i.e., technological progress leads to a widening of...

This study constructs a variety expansion growth model with public research spending, in which public researchers raise the productivity of private R&D. We show that the rela- tionship between public research spending and the growth rate follows an inverted U-shape. This is because public...

This paper constructs a two-region endogenous growth model with productive government expenditure to analyze the relationship between regional redistribution of public input and the welfare of residents in each region. This paper shows that the redistribution policy may be Pareto improving if...

This note reexamines the growth effects of commodity taxation and a manufacturing subsidy. By incorporating endogenous labor supply into a variety expansion model following Grossman and Helpman (1991), we derive new results. First, if households consider leisure to be important, an increase in...

The accumulation of pollution negatively impacts human health. Extreme increases in pollution, in particular, may have lethal implications for human beings|and, indeed, all living organisms. This paper thus devises a new model of economic growth that takes into account these lethal effects of...
