The pace of innovation is related both to the level of investment in innovation and the pool of knowledge from which … innovators can draw. Both of these are endogenous: Investments in innovations are affected by the pool of knowledge and the … and design of IPR affects the extent to which any innovation adds to or subtracts from the pool of ideas that are …

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 …

We also find that the relative importance of knowledge sources varies systematically with the type of innovation … organization that one of the main drivers of differences in productivity is differences in knowledge. We examine a new data set of … detailed measures of knowledge outputs, knowledge investments, and sources of existing knowledge. We find that globally engaged …

knowledge accumulates as technology progresses, then successive generations of innovators may face an increasing educational … negative implications for growth. I develop a formal model of this "knowledge burden mechanism" and derive six testable … sufficiently rapid increase in the burden of knowledge. In cross-section, the model predicts that specialization and teamwork will …

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 …

This paper directs attention at the globalization of knowledge and knowledge creation as the fundamental global driver … of economic outcomes in today's information economy. It documents the globalization of knowledge and spread of scientific …; boosts labor standards; and influences incomes and inequality within and across countries. To the extent that knowledge is …

If a standard deviation in test scores in … later grades translates into a larger difference in knowledge, an intervention's effect on normalized test scores may fall … even as its effect on knowledge does not. We evaluate this hypothesis by fitting a model of education production to …
