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 …

paper, we address this question by investigating how innovation responses to a substantial policy initiative increasing … product market competition interact with the strength of patent rights. We provide empirical evidence of innovation responding … with step-by-step innovation models predicting that product market competition enhances innovation and, more importantly …

Furthermore, there is path dependence in the type of innovation both from aggregate spillovers … and from the firm's own innovation history. Using our model we simulate the increases in carbon taxes needed to allow …
