Using the US states plus the District of Columbia, output-oriented innovative efficiency scores are computed using data envelope analysis (DEA) where total patent counts serve as the measure of innovative output and industry and academic research and development expenditures, and numbers of...

The objective of this paper is to suggest a visual method for identifying departures from normality of the innovations in times series models. The method is based on replacing the variance by the Gini as the measure of variability. The Gini methodology is a rank-based methodology, which takes...

This paper deals with the relationship between knowledge, innovation and regional growth. The study is carried out through the application of nonparametric estimation methods to European data at NUTS2 level. We provide evidence that the share of innovative ...firms plays a more relevant role in...

In this paper, one studies the asymptotic behavior of empirical processes based on consecutive residuals of univariate conditional mean and variance models. These processes are then used to develop tests of serial independence of the innovations. Even if the limiting distributions of the...

We investigate whether the impact of direct support for business investment in R&D and innovation varies over the business cycle. We study whether firms that obtain public support in a recession differ from firms that obtain it during expansions; whether the impact of support is smaller in...

We analyze the dynamic strategic interactions between a manufacturer and a retailer in a decentralized distribution channel used to launch an innovative durable product (IDP). The underlying retail demand for the IDP is influenced by word-of-mouth from past adopters and follows a Bass-type...
