In this paper, we have presented a generalization of Bucci's (2003) model in which have disentangled the monopolistic mark-up in the intermediate goods sector, the intermediate goods share in the final output and the returns to specialization in order to have a better measurement of competition....

We introduce publicly funded education into R&D-based economic growth theory. Our framework allows us to i) explicitly describe a realistic process of human capital accumulation within these types of growth models, ii) reconcile semi-endogenous growth theory with the empirical evidence on the...

We revisit the issue of self-fulfilling “waves of enthusiasm” as stationary rational expectations equilibrium outcomes in endogenous-growth models that merge the quality-ladders with the expanding-variety mechanism. By considering a lab-equipment specification with vertical-innovation...

This paper develops a tournament model of horizontal and vertical R&D under a lab-equipment specification. A key feature is that the overall growth rate is endogenous, as the splitting of the growth rate between the intensive and the extensive margin is itself endogenous. This setup gives rise...

In this paper we build an endogenous growth model where human capital and ideas are complements in the long-run equilibrium and technological progress takes the form of a continuous increase in the number of horizontally differentiated varieties of intermediate inputs. One peculiarity of the...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

I model knowledge (patent) licensing and evaluate intellectual property regulation in an endogenous growth framework where the engine of growth is in-house R&D performed by high-tech firms. I show that high-tech firms innovate more and economic growth is higher when there is knowledge licensing,...

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...

We consider an endogenous growth model with two sectors: an intermediate input (or "upstream") sector and a final product (or "downstream") sector. Innovation takes place in both sectors. Following Gilbert and Shapiro (1990), we define patent breadth as the ability of the innovator to reap...
