We introduce into a Schumpeterian growth model an inventive step, which is a minimum innovation size required for patents, and thus a patentability requirement. We show that in order to satisfy an inventive step requirement, each R&D firm targets only industries in which the incumbentfs...

This paper provides a theoretical explanation for why the presence of asset bubbles can lead to higher economic growth in concurrence with high consumption by using a simple endogenous growth model. In the model economy, long-lived valuemaximizing firms continuously improve the quality of their...

Tax changes are often announced before the implementations and are not permanent but only temporary. R&D firms will optimally adjust their investment decision to a tax schedule accordingly. This paper analyzes how anticipated and temporary tax changes dynamically affect the innovation...

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...

In this paper, we introduce into a Schumpeterian growth model an inventive step: a minimum innovation size required for patents, which is a patentability requirement. We show that each R&D firm targets only the industries that the incumbentfs technology is sufficiently obsolete in order to...

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 studies sustainability of economic growth considering the risk of natural disasters caused by pollution in an endogenous growth model with physical and human capital accumulation. We consider an environmental tax policy, and show that economic growth is sustainable only if the tax...

This paper examines the economic growth effects of limited availability of higher education in a simple endogenous growth model with overlapping generations. With limited availability, the scarcity of human capital keeps its price high and distributes a larger share of the aggregate output to...

This paper investigates a two-country model of capital accumulation with country-specific production externalities. The main concern of our discussion is to explore the presence of equilibrium indeterminacy in an open-economy setting. In contrast to the existing studies on equilibrium...

This paper explores a two-country model of capital accumulation with country-specific production externalities. The main concern of our discussion is to investigate equilibrium determinacy (aggregate stability) conditions in a financially integrated world economy. We show that the...
