A Schumpeterian growth model is constructed where R&D firms innovate to produce better versions of the products or imitate to copy existing innovations. Because firms cannot use their innovations or imitations as collateral, they finance their investment by issuing shares. Households save by...

The paper studies the contribution of human capital on economic growth through its impact on the rate of innovation by formulating an endogenous growth model that combines elements from Romer (1990), Aghion and Howitt (1992), and van Zon and Yetkiner (2003). Using a relatively broad concept of...

We study the negative correlation between natural resource-abundance and long-term income focusing on the savings-investment channel. We first present empirical evidence on this channel and then develop an OverLapping-Generations (OLG) model to study the issue. In this model, savings adjust...

This paper offers a new explanation for the empirically observed inter-industry wage variation. We represent an industry by a small open economy with inter-firm labor mobility. Each industry is characterized by a degree of learning-by-doing, learning-by-hiring, inter-firm mobility costs and...

International trade patterns at the product level are surprisingly dynamic. The majority of trade relationships exist for just a few, often only two to four, years. In this paper, I examine empirically the duration in German import trade at the 8-digit product level from 1995 to 2005. I find...

We reconsider the effects of long run growth on relative factor prices across cones of specialization. We model economic growth as exogenous technological change. Allowing for capital biased technological change with a sector bias and for endogenous commodity prices, we find that economic growth...

We construct a Schumpeterian growth model of a common market with following properties. Households can stay as workers or become researchers at some cost. Workers are employed in production and researchers in R&D. Workers are unionized. A larger common market means a wider variety of products...

During the last twenty years the share of researchers in the workforce has been rising in OECD countries. The consistency of this pattern suggests that it is not a transitional phenomenon. This paper demonstrates that the rise of research can occur in the steady state when schooling inequality...

This paper analyses the effects of globalization, stricter intellectual property rights protection and different labor market policies in a dynamic North-South general equilibrium model with non-scale growth. To this aim, we generalize the Schumpeterian product-lifecycle model of Dinopoulos and...
