Empirical studies often find significant and positive R&D spillovers across firms. In this note, we incorporate this spillover effect into a scale-invariant quality-ladder model. We find that the modified model features multiple steady states (i) a high-R&D steady state, (ii) a low-R&D steady...

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...

This paper incorporates home production into a real business cycle (RBC) model of a small open economy to provide a parsimonious explanation of the empirical pattern of international business cycles in developed economies and emerging markets. It is well known in the literature that in order for...

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...

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...

This paper develops an R&D-growth model and calibrates the model to aggregate data of the US economy to quantify a structural relation ship between patent length, R&D and consumption. Under parameter values that match the empirical flow-profit depreciation rate of patents and other key features...

What are the effects of increasing developing countries’ intellectual property rights protection on growth, welfare and income inequality in the global economy? To analyze this question, we develop a two-country R&D-growth model with wealth heterogeneity. We find that the North experiences...

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...
