Abstract Wineries in the “old world” export almost 40% of their production. This study analyzes influence vertical and horizontal networks on performance. We draw a sample 183 Spanish wineries examine main independent variables using two-step Heckman model. find positive effects and—at somewhat lower level—downstream (JEL Classifications: L66, M16, Q13)

In the paper we propose nonparametric approaches for elearning data. In particular we want to supply a measure of the relative exercises importance, to estimate the acquired Knowledge for each student and finally to personalize the e-learning platform. The methodology employed is based on a comparison between nonparametric statistics for kernel density classification and parametric models such ...

We apply different matched-pair methods to evaluate the policy of sustaining the adoption of advanced manufacturing technologies by Swiss firms and we compare it in decomposing the selection bias. In this aim we present the evaluation problem, the decomposition of the selection bias and the estimation techniques used. We base our study on the J. Heckman and al. (1998)’s paper.
