This paper studies how the strength of intellectual property rights (IPRs) affects investments in biological innovations when the value of an innovation is stochastically reduced to zero because of the evolution of pest resistance. We frame the problem as a research and development (R&D)...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

In this note we study the distortions in an endogenous growth model developed by Grimaud and Tournemaine (2007), where new pieces of knowledge are produced in a R&D sector and used to reduce pollution emissions. Using this model along with a realistic calibration, we conclude that the economy...

This paper assesses whether the most important R&D technologies at the roots of second-generation Schumpeterian growth theories are consistent with patenting and innovation statistics. Using US manufacturing industry data, we estimate various systems of simultaneous equations modeling the...

This paper reports research focused on the inter-temporal resource allocation requirements of a program of technological changes that would halt global warming by completing the transition to a "green" production regime (i.e., zero net CO2-emissions) within the possibly brief finite interval...

This paper presents an endogenous growth model with population growth and an inter-generational spillover of human capital: we consider the ``local home environment externality conceptualized by Galor and Tsiddon (1997a). The model will generate a negative relationship between the population...

We derive a model of endogenous growth with physical capital, human capital and technological progress through quality-ladders. We introduce welfare-decreasing pollution in the model, which can be reduced through the development of cleaner technologies. From the quantitative analysis of the...

In this paper we study the economic determinants of the inter-sectoral distribution of skilled workers and the long-run consequences of imperfect competition on growth within an R&D-based growth model with human capital accumulation. We find that steady-state growth is driven only by incentives...
