The legal monopoly granted by the patent system has often been criticized for its inefficiency, which is exacerbated by the peculiarities of knowledge as a public good. In this paper we aim at studying more deeply the latter concern. Hence we build a model in which monopolistic exploitation does...

Following Gilbert and Shapiro (1990), we define … in the downstream sector increases the incentives of agents to do R&D in that sector but discourages innovation in the … downstream sector slows it down. We show that regardless of parameter values, welfare maximizing, rate of innovation maximizing …

Using a vertical differentiation model of endogenous growth with stochastic R&D activity, we characterise the optimal patent lifetime a government would set in order to maximise economic growth. We show that a finite patent lifetime does exist and is unique provided that the expected rate of...

An endogenous growth model is developed where each period firms invest in researching and developing new ideas. An idea increases a firm's productivity. By how much depends on how central the idea is to a firm's activity. Ideas can be bought and sold on a market for patents. A firm can sell an...

We show a causal impact of immigration on innovation and dynamism in US counties. To identify the causal impact of … recent decades. We show four main results. First, immigration has a positive impact on innovation, measured by the patenting … impact of immigration on innovation percolates over space, but spatial spillovers quickly die out with distance. Fourth, the …

Based on a standard idea-based model of endogenous growth we test the hypothesis that regional innovative activity is path-dependent, and investigate the geographical scope of knowledge spillovers. Using data for West-German regions, two alternative indicators of the stock of knowledge are...
