This paper studies the macroeconomic implications of firm-branding activities. We show empirically that firms build market share by creating new brands, developing their existing brands, and buying established brands from other firms. Sales and prices of the underlying branded products tend to...

We study an endogenous growth model where a profit-motivated R and D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones which are produced by a monopoly owned by the inventor. We show that...

We analyse how spatial disparities in innovation activities, coupled with migration costs, affect economic geography, growth and regional inequality. We provide conditions for existence and uniqueness of a spatial equilibrium, and for the endogenous emergence of industry clusters. Spatial...

This paper aims at analyzing the e ects of lobbying over economic growth and primarily welfare. We model explicitly the interaction between policy-makers and firms in a setup where the latter undertakes political contributions to the former in exchange for more restrictive market regulations...

I study the joint determination of market structure and growth in an oligopolistic economy. Firms run in-house R&D programs to produce over time a continuous flow of cost-reducing (incremental) innovations. In symmetric equilibrium, the dispersion of resources across firms prevents the...

This paper studies the effect of competition on firm innovation by developing a discrete-time endogenous growth model where multi-product firms do two types of innovation subject to friction in technology spillovers. Firms improve their existing products through internal innovation while...

The patents power is threefold: first, they are important to state the property right's appropriability of an invention; second, they are necessary in order to secure financing for starting a new venture; third, they are fundamental in order to recoup the positive R&D cost investment. The main...

Africa: A continent is waking up. Not through aid or wealth from the exploitation of natural resources, but through a technological revolution. The access to affordable mobile telecommunication. Inspired by deregulation and pioneered by local champions who have taken a lead in what is today's...
