摘要：We introduce a racing model with multiple product generations, product innovation, spin-outs, and licensing. Industry conditions and innovation characteristics affect who wins the race and who markets the resulting product. Small firms market their innovations when they pioneer a new generation or improve quality in a young generation and license their innovations in mature generations. If old generation leaders ever market improvements in young generation goods, they do so early on. Leadershi...

摘要：European economic growth has been weak, compared to the US, since the 1980s. In previous work (Krueger and Kumar, 2003, NBER Working Paper No. 9410), we argued that the European focus on specialized, vocational education might have been effective during the 1960s and 1970s, but resulted in a growth gap relative to the US during the subsequent information age, when new technologies emerged more rapidly. In this paper, we extend our framework to assess the quantitative importance of education po...

摘要：We look at disaggregated imports of various types of equipment to make inferences on cross-country differences in the composition of equipment investment. We make three contributions. First, we document strikingly large differences in investment composition. Second, we explain the differences as being based on each equipment type's degree of complementarity with other factors whose abundance differs across countries. Third, we show that the composition of capital has the potential to account f...

摘要：We develop a new general equilibrium growth accounting framework that features increasing returns to scale, imperfect competition and incorporates technological revolutions into the description of technical progress. We propose a way to tell apart revolutionary changes in technology and incremental innovations using stock market data. We use our framework to jointly estimate the overall embodied TFP change during 1953-1995 and the aggregate output elasticity. We find that the IT revolution rai...

摘要：Innovations and their adoption are the keys to growth and development. Innovations are less socially useful, but more profitable for the innovator, when they are adopted slowly and the innovator remains a monopolist. For this reason, rent-seeking, both public and private, plays an important role in determining the social usefulness of innovations. This paper examines the political economy of intellectual property, analyzing the trade-off between private and public rent-seeking. While it is tru...

摘要：We examine the diffusion of more than 20 technologies across 23 of the world's leading industrial economies. Our evidence covers major technology classes such as textile production, steel manufacture, communications, information technology, transportation, and electricity for the period 1788-2001. We document the common patterns observed in the diffusion of this broad range of technologies. Our results suggest a pattern of trickle-down diffusion that is remarkably robust across technologies. M...
