This study constructs a variety expansion growth model that integrates basic research to analytically examine its effects on household welfare. In our approach, the research sector consists of applied and basic research components. The former creates blueprints and expands the variety of goods...

There is considerable debate regarding the use of intellectual property rights (IPR) to spur innovation in the software industry. In this paper we focus on the choice of intellectual property right regimes and industry growth. We begin by developing a growth optimal mixture of open source and...

We extend the basic Schumpeterian endogenous growth model by allowing incumbents to undertake innovations to improve their products, while entrants engage in more “radical” innovations to replace incumbents. Our model provides a tractable framework for the analysis of growth driven by both...

The legal monopoly granted by the patent system has often been criticized for its inefficiency, which is exacerbated by the peculiarities of knowledge as a public good. In this paper we aim at studying more deeply the latter concern. Hence we build a model in which monopolistic exploitation does...

We study the interaction of customer capital and productivity through brand reallocation across firms. We develop a firm dynamics model with brands as transferable customer capital, heterogeneous firm productivity, and variable markups. We study the matching process between transferable brand...

This paper combines horizontal and vertical innovations to build an endogenous growth model that allows for structural change. Older technologies are continuously replaced by newer ones due to creative destruction and new technologies appear as a result of horizontal innovations and as a result...

This paper explores whether the patent law and intellectual property rights (IPR) system have resulted in innovation in China during the reform period. It appears that the patent laws have produced a stock of patents, where the success rates of patent applications are fairly uniform across the...

It is well known that research and development (R&D) is an important engine for economic growth. Also, initial wealth inequality and subsequent economic growth are well known to be related. This paper links inequality and R&D-driven growth. It shows that in a class of economies where R&D is the...
