The paper illustrates a differential evolution (DE) algorithm to calculate the level-cuts of the fuzzy extension of a multidimensional real valued function to fuzzy numbers. The method decomposes the fuzzy extension engine into a set of "nested" min and max box-constrained op- timization...

This paper investigates the role of wages, education and innovation in shaping employment structures in manufacturing and services of five European countries (Germany, France, Spain, Italy and United Kingdom), with specific respect to skills in the long term (1999-2011). Using data on employment...

In this article we extend the model developed by Bogliacino and Pianta (2013a, 2013b) on the link between R&D, innovation and economic performance, considering the impact of innovation of export success. We develop a simultaneous three equation model in order to investigate the existence of a...

This paper examines the state of Europe’s industry and competitiveness in the current crisis and provides the rationale for a new industrial policy at the European level. Section 1 documents the decline of EU industry and the losses in outpud resulting from the crisis started in 2008. Section...

The main aim of this paper is to study the propensity of consumer cooperatives (Coops)to use incentive schemes in situations of strategic interaction with profit-maximizing …rms (PMFs). Our model provides a reason why Coops are less prone than PMFs to pay variable bonuses to their managers. We...

One of the standard predictions of the agency theory is that more incentives can be given to agents with lower risk aversion. In this paper we show that this relationship may be absent or reversed when the technology is endogenous and projects with a higher e¢ ciency are also riskier. Using a...

Start-ups increasingly find the prospect of university-industry collaborations to be a powerful driver of innovation and entrepreneurship activity. Moreover, at the geographical level, they are attracted by teaching and research institutions, either public or private. This paper focuses on the...

In this paper we prove the existence of full measure unbounded chaotic attractors which are persistent under parameter perturbation (also called robust). We show that this occurs in a discontinuous piecewise smooth one-dimensional map f, belonging to the family known as Nordmark's map. To prove...

In 2008, Eurostat updated the Statistical Classification of Economic Activities (NACE) from NACE Rev.1 to NACE Rev.2. Eurostat provided correspondence tables to facilitate conversion between the two coding system at the 4 digit level. However, due to multiple correspondences, there is a need for...

In this paper we present a simple model of university-industry collaborations with heterogeneous agents, which is the standard case of technology transfer. We study the characteristics of the matching process, that makes this exchange in technology transfer either efficient or unfeasible. We...
