Abstract
We analyze the relationship between cultural values, societal values and the type of the economy with necessity-driven, opportunity-driven and improvement-driven entrepreneurship. We take into account GEM's data from 56 countries. These reports are also used to characterize the three types of entrepreneurship, the societal values and the type of economy. We approach national culture through the five dimensions of Hofstede's work on cultural values using the Values Survey Module 2013 (based on Hofstede's work). Cultural values marginally explain necessity-driven and opportunity-driven entrepreneurship. In turn, societal values only explain improvement-driven entrepreneurship. Finally, the type of economy is important in explaining necessity-driven and opportunity-driven entrepreneurship, however it is of no added value in explaining improvement-driven opportunity. One needs to be cautious when drawing general conclusions as we believe that societal values are failing to capture differences among the types of entrepreneurship analyzed.

Abstract
The internationalization of firms is a growing important phenomenon in the Economy. Thus, to face the new competitive challenges of globalized markets, industrial small and medium-sized enterprises (SMEs) need to implement new organizational approaches to take on new challenges in international markets. Based on a case study, this chapter reviews the literature on internationalization theories. Drawing on the network-based approach and on the resource-based view of the firm, we examine how collaborative new product development processes played a fundamental role in the internationalization process of a SME using a relationship-based perspective. The featured case concerns to a successful ex-small technical textile firm that leveraged its competitive strategy, climbed up the value chain, and extended its international activities following a technology-based path.

Abstract
The existing literature on internationalization and purchasing is vast; however, the inward internationalization perspective is an under-researched topic. In this chapter, the authors review the literature on internationalization of small and medium enterprises (SMEs) to understand the main reasons behind international purchasing and the role of experience on internationalization. Using a survey and descriptive statistics, the results from 56 respondents show that SMEs source from a small number of countries and hold those relationships for several years. The main reasons underlying international purchases are lower prices and better product quality, regardless of goods availability on the domestic market. This chapter has some limitations concerning its exploratory nature, pertaining to its sample size. Some future research avenues are presented such as a deeper look on how internationalization processes differ when SMEs begin their activity by inward rather than by outward activities.

Abstract
dado o interesse premente, não só da comunidade académica como do mundo empresarial, sobre a internacionalização das empresas, esta investigação faz uma revisão da literatura empírica sobre a internacionalização de Pequenas e Médias Empresas (PME) no continente americano, a partir das principais bases de dados académicas. Partindo de um conjunto de 329 artigos, este estudo analisa em pormenor 39 destes, entre 1999 e 2014, contribuindo significativamente para o desenvolvimento do conhecimento e da compreensão da investigação feita até à data nesta área. Com esta análise, foram identificadas tendências e padrões, podendo concluir-se que a investigação feita sobre a internacionalização de PME centra-se nos Estados Unidos e no Canadá, influenciada sobretudo por quatro grandes tópicos: teorias da internacionalização, estratégia, desempenho e perspetiva internacional. Conclui-se igualmente que há uma predominância quantitativa. As conclusões e interpretações sobre oportunidades para futuras investigações são de relevância tanto para a comunidade académica como para a empresarial.

Abstract
Social entrepreneurship is emerging as an innovative approach for dealing with complex social and environmental needs, and is an important lever for the development of a sustainable society. Social entrepreneurship and related concepts have had a growing attention in the academy, giving rise to dissimilar approaches in the United States of America and in Western Europe. Despite the importance of the Third Sector in Portugal, it has been difficult to set ideal definitions for social entrepreneurship, social entrepreneur and social enterprises. By means of a qualitative study involving four Portuguese social ventures, this chapter identifies contemporary socio-cultural and economic factors that foster social innovation and intervention in Portugal, and contributes to understand the role of social entrepreneur in this context. © 2025 Elsevier B.V., All rights reserved.
