The goal of this study was to analyze the emergence of treatment standards associated with the adoption of anti-HIV drug innovations in the empirical setting of Italian clinical practice. Due to the rapid pace of technological change and the initial uncertainty concerning capabilities and...

This paper proposes a new approach to explain the long-term evolution of a supplier industry. The network of vertical relations between suppliers and buyers is identified as a determinant of the concentration of the supplier industry and of the dynamics of market shares. The vertical structure...

The paper develops the argument that the long-term structural evolution of an industry depends on the evolution of a vertically-related, downstream industry. We analyse two pairs of vertically-related industries, the jet and turboprop aircraft and engine industries, since the first introduction...

We test recent theory on the benefits of auctions and bargaining as alternative procurement mechanisms using data on the procurement of medical devices by Italian hospitals. Theory suggests that auctions perform well when cost control is the key concern, but are less effective at producing the...

The paper explores the idea that properties at the level of firms coevolve with more aggregate properties at the level of market institutions in the dynamics of industries. We propose that the structure of network of vertical relations limits the effect of increasing returns at the firm level....

A careful case study of the entire history of the turboprop engine industry (1948-1997) is offered as an example of non shakeout pattern. The persistence of high concentration is not associated to the exit of smaller manufacturers, but instead a stable coexistence of generalist and specialist...

This paper addresses the problem of the general validity of models of the industry life cycle, which have been proposed to analyse the long-term evolution of many industries, exhibiting a typical pattern of shakeout. We study a case of non shake-out in the commercial jet aero-engine industry,...

This paper provides a novel contribution for specifying the role of demand for technological competition. The focus is on the analysis of the mechanisms of technological learning and spillovers occurring in different structures of networks of vertically-related industries. The paper offers a...

The decision to adopt e-commerce technology depends on a variety of variables. This paper explores the relative importance of structural firm-specific variables, the intrinsic value of the technology, expectations concerning the evolution of the technology, and the adoption behaviour of other...
