This paper considers leisure externalities in a Lucas (1988) type model in which physical and human capital are necessary inputs in both sectors. In spite of a non-concave utility, the balanced growth path is always unique in our model which guarantees global stability for comparative-static...

In this paper we explore the effects of monetary policy on the number of firms, firm market size, ination and growth in a Schumpeterian growth model with endogenous market structure and cash-in-advance (CIA) constraints on two distinct types of R&D investment - in-house R&D and entry investment....

By setting up a simple Romer-type (1989) endogenous growth model embodying a political trade union (rather than the traditional economic labor union), this paper explores the effects of unionization on unemployment, growth and welfare by highlighting the essence of internal conflict within the...

This paper studies a class of AK-type growth models with public capital stock and elastic labor supply. The government taxes both factor incomes and conduct expenditure. To rationalize the taxation, government expenditure affects the productivity of private sectors. It shows the existence of a...

This study analyzes the effects of inflation on R&D and innovation-driven growth. In the theoretical section, we incorporate money demand into a quality-ladder model with elastic labor supply and derive the following results. If the elasticity of substitution between consumption and the real...

This study develops an R&D-based growth model that features both vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. Specifically, we analyze the growth and welfare effects of patent protection in the form of...

This paper uses a one-sector, endogenous growth model to study optimal composition between public investment and consumption in government expenditure and its relationships with economic growth. Assuming a benevolent government which maximizes a representative household’s lifetime utilities,...

This paper provides a survey on studies that analyze the macroeconomic effects of intellectual property rights (IPR). The first part of this paper introduces different patent policy instruments and reviews their effects on R&D and economic growth. This part also discusses the distortionary...

In the US, defense R&D share of GDP has decreased significantly since 1960. To analyze the implications on growth and welfare, we develop an R&D-based growth model that features the crowding-out and spillover effects of defense R&D on civilian R&D. The model also captures the effects of defense...

How do intellectual property rights that determine the market power of firms influence the effects of monetary policy on economic growth and social welfare? To analyze this question, we develop a monetary R&D-based growth model with elastic labor supply. We find that monetary expansion reduces...
