In this paper we develop a simple endogenous growth model with two competing production technologies and learning spillover effects between firms that use the same technology. Investments are directed to the technology with highest current and expected returns. Since current investments increase...

The usual models of endogenous growth treat knowledge codification as a byproduct of R&D and as costless. In contrast to this, one can observe great efforts of private firms for the purposeful codification of knowledge. We incorporate costly knowledge codification in an overlapping generations...

We develop an endogenous growth model to study the long run consequences of offshoring with firm heterogeneity and incomplete contracts. In so doing, we model offshoring as the geographical fragmentation of a firm's production chain between a home upstream division and a foreign downstream one....

Evidence shows that firms build their market position by consistently investing in R&D over time and accumulating knowledge protected by secrecy, patents and other appropriability devices. To explore the macroeconomic implications of this fact, I construct an economy where oligopolistic firms...

As a factor influencing productivity, a country's own research and development to generate new technology is more important than that of the average foreign country. It is generally difficult to separate the effect of importing intermediate goods with embodied technology from the effect of other...

The economic prosperity of a region is largely dependent on the accumulation and diffusion of knowledge. In this paper, the scale effects as well as the resource reallocation effects of intra- and interregional knowledge transmission are analysed. Within a model, the optimal levels of knowledge...
