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...

In this paper we combine a model of Ricardian comparative advantages as in Dornbusch et al. (1977) with Grossman and Helpman's (1991) quality ladder model and derive the consequences of asymmetric IPRs protection for the pattern of trade and the world rate of growth through innovation. Our...

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...

We study a dynamic general equilibrium model where innovation takes the form of the introduction of new goods whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are adapted to be produced using unskilled labor. Our...

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...

I model knowledge (patent) licensing and evaluate intellectual property regulation in an endogenous growth framework where the engine of growth is in-house R&D performed by high-tech firms. I show that high-tech firms innovate more and economic growth is higher when there is knowledge licensing,...

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...

In this paper I build a North-South model of international trade, economic growth and search-frictional unemployment in the North. Growth is driven by a process of creative destruction in the North followed by imitation in the South. I study the effects of intellectual property rights protection...

I analyze the impact of intellectual property and product market competition regulations on innovation and long-run growth in an endogenous growth model with two R&D performing sectors. I show that strengthening intellectual property rights and competition in a sector increases its R&D...
