This paper is an experience report on an initiative to incorporate requirements engineering practices into the development process of two large corporations. The project was framed by a government program to foster collaboration between academia, industry, and government agencies. Its expected result—proposals for cooperative work—is in itself a major challenge, since it was not decided from th...

In a multi-industry growth model, firms require external funds to conduct productivityenhancing R&D, and face financing constraints. The cost of research differs across industries, so that financing constraints hinder productivity growth in some industries more than in others. Equilibrium industry dynamics map into a differences-indifferences regression specification where industry growth depen...

This paper contributes to the debate on the inducement of environmental innovations by analysing the extent to which endogenous inducement mechanisms spur the generation of greener technologies in contexts characterized by weak exogenous inducement pressures. In the presence of a fragile environmental regulatory framework, inducement can indeed be endogenous and environmental innovations may be...

La technologie blockchain est un réseau distribué sur des machines décentralisées qui permet d’effectuer et de valider transactions. Le terme recouvre usages divers le marché bancaire depuis quelques années. En considérant l’architecture la l’infrastructure bancaire, nous clarifions les utilisations ces technologies à partir différe...

The convergence features of an Endogenous Growth model with Physical capital, Human Capital and R&D have been studied. We add an erosion effect (supported by empirical evidence) to this model, and fully characterize its convergence properties. The dynamics is described by a fourth-order system of differential equations. We show that the model converges along a one-dimensional stable manifold an...

We apply various re nements of survival regression to assess the results of some basic speci cations based on product life cycle theory for the case of a data set of the German automobile industry. The methods applied pay attention to biases in the coe cient estimates and the standard errors, the discrete nature of the duration data and the presence of unobserved heterogeneity. Robust estimatio...

A policy debate continues about the relative merits and and negative consequences of federal policies that encourage patent protection to university research results. Given the importance of university research for innovation in many industries, the effects of such policies are of critical importance to firms. This paper examines the impact of the increase in university patenting on the effecti...

This paper contributes to the debate on the inducement of environmental innovations by analysing the extent to which endogenous inducement mechanisms spur the generation of greener technologies in contexts characterized by weak exogenous inducement pressures.

We study the combined effects of uncertainty and competition on the timing optimization of investments in complementarity inputs for non-preemption duopoly (leader-follower) markets with either a weakpatent system where spillover-knowledge is allowed or a strong-patent system where proprietaryknowledge holds. We find that, for some input-sequencing investment scenarios, ex-ante and (expected) e...

This paper investigates the effect of Internet technology on how firms access export markets directly or via intermediaries. Empirical evidence suggests that technology diffusion is geographically localised, with knowledge spillovers from neighbouring adopters decaying quickly over short distances. To address the potential endogeneity of Internet adoption, I construct an instrument that capture...
