This paper examines the empirical dynamics of countries' technological specialization in six technology fields using distribution dynamics, a methodology involving non-parametric estimation of probability distributions and Markov stochastic kernels for each field. Innovation in all the fields is...

This paper is a first attempt towards the full inclusion of a group of variables greatly studied in the current literature on innovation and industrial economics -such as knowledge links and the structure of competition and collaboration in a sector -into the determinants of the international...

This paper studies imports of quality products. The issue is more and more relevant because of the strong evidence of such differentiation in international trade. We first derive individual demand, then we aggregate without using the representative consumer hypothesis. We find that quality...

Widespread adoption of a new capital-embodied technology often requires a continuous flow of incremental innovations, aimed at making renting the new machine a viable alternative to buying it, or at dividing it up in modular elements, and possibly allowing for product range extension....

Intra-Industry Trade implies similar trade specialisation and is often associated with product differentiation. Differentiation depends on either quality or characteristics and two-way flows can be divided accordingly. If quality matters, we can measure relative quality of exports and imports....

This work is concerned with the determinants of innovations and competition of technologies in the case of the Local Area Network industry. It focuses in particular on two suppliers of LAN components: the access technology industry and the internetworking industry. Two elements driving the...

The paper focuses on some organizational dynamics that have characterized pharmaceutical industry in the last thirty years, when biotechnology and the development of life sciences have defined a new technological paradigm, reshaping many aspects of the industry, especially the organization of...

This paper estimates sectoral demand functions for Italian imports from European Union countries, Japan, Canada and United States. Evidence of two-way flows and product differentiation is an accepted regularity of international trade. We have tried to include considerations of differentiation in...

This paper explores the rules which regulate market shares dynamics within industries jointly with the mechanisms underpinning a process of general evolution in which n sectors grow at different rates and structural change takes place. It introduces a selection equation, which allows for...

In this paper we present a model of the long term dynamics of market structure and innovation in the pharmaceutical industry in a history friendly way. Our results show a strong increase in concentration in each therapeutic area, but a rather low level of concentration in the overall market....
