We model non-drastic technological innovation in a duopoly model with differentiated products. We derive profit functions for both firms which depend on only one variable, the technological gap. As our model derives product demands directly from agent utility we are able to fully describe the...

We highlight one difference in predictions between Romer's expanding variety model and the Schumpeterian quality-ladder model, when there exists a cash-in-advance (CIA) constraint on manufacturing. In the expanding variety model, a higher nominal interest rate decreases growth, and a negative...

We establish the relation between optimal subsidy rates and spillovers from the sequential adoption of a new technology, we find that they evolve in the same direction over time. We show that spillovers, hence the subsidy rates, need not be monotonic. We show that when subsidy rates are...

In this note we investigate socio-technical transition pathways concentrating our attention on innovation niches formations. Specifically, we present a methodological conceptualization of innovation-niches and propose a preliminary protocol, based on a Social Network Analysis (SNA), aiming to...

This paper focuses on the innovation gap between countries in the Euro-Mediterranean (Euromed) area and its implications in terms of growth and convergence. Using a large set of innovation variables, we estimate a growth model à la Barro which shows that differences in innovation between...

This article models the intertemporal behaviour of a firm that sets product prices and simultaneously invests in R&D. The model shows that the dynamic pricing rule follows the evolution of the production cost and is independent of the evolution of the product quality. Thus, process innovation,...

The August 15th 2013 Shanghai Academic Rankings of World Universities (ARWU) should leave policy makers wondering about whether the impressive growth experienced by ‘latecomers in the industry' has moved hand-in-hand with contribution to knowledge by means of scientific publications. Against...

This work proposes to analyse learning opportunities in North-South trade. Without a direct measure of knowledge transmission, we use export and import sophistications in order to evaluate learning effects for Sub-Saharan African (SSA) and Developing Asian (DA) countries with regard to their...

We study innovation and R&D investments made from 2008 to 2010 by UK companies that were the targets of leveraged buyout (LBO) in previous years. We find that overall, LBO companies do not exhibit lower innovation and R&D investments than non-LBO companies during the crisis, with other things...

Technology transfer and, more broadly, knowledge spillover from universities to industry has become increasingly studied as universities have become charged with driving local economic growth. This study offers several empirical improvements over prior efforts to measure the aggregate local...
