We study a dynamic general equilibrium model where innovation takes the form of the introduction new goods, whose … production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are … substitution between goods and other parameters. Third, we show that the interplay between innovation and standardization may lead …

Innovation is often predicated on discovering useful new combinations of existing knowledge in highly complex knowledge …, and particle physics. We develop a combinatorial-based knowledge production function and embed it in the classic Jones …. This production function is a generalization (and reinterpretation) of the Romer/Jones knowledge production function …

In this study, we find that patent … in question, which we interpret as evidence of a significant role played by social capital in promoting knowledge … find strong evidence in support of the enduring social capital hypothesis; social ties that facilitate knowledge transfer …

We conduct the first empirical test of the knowledge burden hypothesis, one of several theories advanced to explain … increasing team sizes in science. For identification, we exploit the collapse of the USSR as an exogenous shock to the knowledge …

The development prospects of a poor country depend in part on its capacity for innovation. The productivity of its … innovators depends in turn on their access to technological knowledge. The emigration of highly skilled individuals weakens local … knowledge networks (brain drain), but may also help remaining innovators access valuable knowledge accumulated abroad (brain …

linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its … strength. Past innovation network structures are calculated using citation patterns across technology classes during 1975 … predictive power on future innovation after 1995. This pattern is consistent with the idea that when there is more past upstream …

interplay of these two localized externalities and their impact on regional innovation. We examine MSA-level patent data during … the period 1975-2000 and find that innovation output is higher where large and small labs coexist. The finding is robust …

After presenting a motivating model focusing on the … choice between incremental and radical innovation, and on how managers of different ages and human capital are sorted across … measures of creative innovations proxy for innovation quality (average number of citations per patent) and creativity (fraction …
