Our paper "Generalized Hukuhara Differentiability of Interval-valued Functions and Interval Differential Equations", appeared in Nonlinear Analysis 71 (2009), contains some imprecisions. In this note we correct them and give few new results on the topic.

In the present paper, using novel generalizations of the Hukuhara difference for fuzzy sets, we introduce and study new generalized differentiability concepts for fuzzy valued functions. Several properties of the new concepts are investigated and they are compared to similar fuzzy...

The patterns and mechanisms of job creation in business services are investigated in this article by considering the role of innovation, demand, wages and the composition of employment by professional groups. A model is developed and an empirical test is carried out with parallel analyses on a...

Inequality within advanced countries has returned to levels typical of a century ago. At the global level it remains extremely high despite the rapid growth of major developing countries such as China, India and Brazil. This makes inequality a major economic issue, social problem and political...

The model and the empirical test developed in this paper address the determinants of structural change for six major European economies from 1995 to 2007. The performances of sectors are explained by the unfolding of uneven technological opportunities and different conditions of demand. Building...

EU Structural Funds represent by far the main source of funding for innovation in general and for eservices in particular in the lagging regions of Europe classified into the “Convergence” objective. The paper explores the amount of resources dedicated to public e-Services and Information...

The aim of this paper is to extend Hamilton and Slutsky's (1990) endogenous timing game by including the possibility for players to cooperate. At an initial stage players are assumed to announce both their purpose to play early or late a given duopoly game as well as their intention to cooperate...

The application in Economics of methods and tools originally thought for other disciplines is not new. In this paper we show how the compartmental approach, typical of Biology, Medicine, Chemistry, etc., can be used as a tool to represent the heterogeneity of the agents and introduce it into the...

Consumer co-operatives constitute a highly successful example of democratic forms of enterprises operating in developed countries. They are usually organized as medium or large-scale firms competing with profit seeking firms in retail industries. In this paper we model such a situation as a...

Microeconomics studies group behaviour by using the representative member model. However, there is growing evidence that there can be significant differences between choices made by single individuals and those made by the same individuals when choosing collectively. This study investigates the...
