Most countries face important economic, social and environmental challenges and are strongly committed to invest in research and development (R&D) activities to help support the long-run economic sustainable growth. This paper aims to extend the previous research on macro-economic growth models and introduces endogenous variables to determine the amount of investments in R&D activities.

The model considers four different criteria and six economic sectors and aims at finding the optimal allocation of labor across different sectors. The model also endogenously determines the amount of investments in pollution abatement activities together with energy-related R&D efforts. The paper presents an application to the case of Kazakhstan, an emerging Asian country, that aims to become one of the top 30 most developed countries in the world by 2050.

The model shows the limits of the Kazakh agenda that identified too ambitious goals as the country has to go through a sociotechnical transition that involves a range of modifications in institutional structures, together with changes in user practices and the technological dimension. Kazakhstan should invest more in R&D activities able to develop sustainable energy sources to face the current electricity consumption demand and to reduce the greenhouse gas emission in the future.

The paper provides valuable knowledge for researchers and policy makers interested in the impact of R&D on the long-run economic sustainable growth.

Energy and environmental concerns have gained a significant role in public policy agenda as well as in energy economics literature. As policies often rely on imprecise information on data and goals, fuzzy goal programming (FGP) modeling is a relevant choice to evaluate multi-criteria sustainability. This technique is suitable for the analysis of the Europe 2020 strategy plan dealing with several possibly conflicting objectives in economy, environment, energy and employment. The paper aims to discuss these issues.

The paper presents a FGP model for sustainable implementations for all European Union (EU) countries with respect to Europe 2020 policy goals and provides insights for decision makers to better satisfy conflicting criteria by suggesting optimal allocations of workers in several economic sectors.

The analysis shows an overall great performance of European Union countries in the environmental and social criteria and outlines the needs for significant additional policy measures to reduce energy consumption while increasing the economic output. Comparing the performance of countries within the European Union between those who adopted the euro and those who maintained national currencies shows that Euro countries tend to perform worse in terms of Europe 2020 sustainability, opening opportunities for further research to better investigate on the causes and determinants of these differences.

The paper presents a conceptual model of sustainable development that improves understanding of the concept and reconciles highly competing policy objectives in a common framework. Applying this model to all European Union countries offers both comparison and policy recommendations at a large new scale.

The aim of this paper is to analyse why Italian small and medium enterprises (SMEs) pursue internationalization (current and future entry modes, motivations, advantages and difficulties) and how they go about it, with reference to four key areas: innovation and technology, networking, environmental approach and human resource (HR) competences.

A questionnaire was distributed to 792 enterprises with a response rate of 24.37 per cent. Data were collected using the computer assisted web interviewing (CAWI) method and processed with Rasch analysis, Principal Components Analysis and Cluster analysis methods.

The paper presents the results of a quantitative research on SMEs located in the Province of Monza and Brianza – one of the most productive territories in Italy. Four different clusters emerged with specific approaches. Briefly, this paper points out that: innovation is mostly linked to the product and is incremental; HR and their competences are crucial for facing complex markets; the green issue is not dominant (it is considered only for saving energy and reducing cost production); and networking is not a key issue (except informal relations, contractual agreements and strategic alliances).

The research could be extended: through a longitudinal survey on the same sample; by covering different territories on the same topics. The cluster analysis identifies potential guidelines for entrepreneurial behaviour in respect to key factors for exiting from the economic and financial crisis: innovation and technology, formal and informal networks, the “green” approach, HR training.

This paper presents a new interdisciplinary approach that may work beyond country boundaries, providing a new basis to the debate on the internationalization of SMEs.
