A Polarization Index for Overlapping Groups

The well‐known index of income bipolarization proposed by Wolfson (1994) requires two groups to be split according to the median income and, therefore, to be non‐overlapping. The aim of this paper is to propose a new polarization index in the spirit of the Wolfson index. It allows for any possible partition of the population in two or more (also overlapping) groups. The new index maintains the simplicity and immediate comprehension of the Wolfson index, though being much more flexible. An application is then provided for German and Italian income data.

Risk of poverty in Southern Europe

We analyze whether the risk of poverty deteriorates with the crisis in France, Greece, Italy and Spain, for different categories of households, individual features and policy instruments, such as the regional European Structural Funds. We find that the impact of the economic recession was heterogeneous, deteriorating the status of temporary workers, self-employed, single and female-headed households, while the risk of poverty decreased relatively for larger households with dependent children and elderly members. We also find that targeted funds toward human capital investment are associated to decreasing the risk of poverty, but the crisis slowed down their effects.     

Taking Actively Advantage of MNCs’ Presence

In this paper, not only do we posit that the presence of a multinational corporation may entail significant benefits for the host economy and local firms’ performance, but also that these benefits can be actively sought and dynamically reinforced by local firms through the development of intense, embedded customer–supplier relationships. Building on the relational view, we argue that this may happen through the commitment of resources to relation-specific investments. Our hypotheses find support in a sample of SMEs suppliers of ST Microelectronics, the fourth largest producer of microelectronic components in the world. We show that by making relation-specific investments, local firms can grow quantitatively and qualitatively, improve their innovativeness, and acquire new clients.     

Financing obstacles and growth: an analysis for euro area non-financial firms

This paper investigates the determinants of financing obstacles (FOs) and their impact on firm growth. For this purpose, we rely on both balance sheet data and survey data for a sample of non-financial firms in the euro area. The latter allows us to devise a direct measure of the firms’ probability of facing FOs. First, our results indicate that FOs are linked to characteristics such as the age of the firm, its size, its sales level or the sector in which it operates. Second, we find that, though based on few variables, our measure of FOs appears to be relevant in explaining firm growth in four out of the five countries considered; likewise, growth is found to be positively linked to cash flow.     

Straight to the Core — Explaining Union Responses to the Casualization of Work: The IG Metall Campaign for Agency Workers

The existing literature provides different accounts on the strategies of unions regarding marginal workers. It has been argued that under increasing labour market segmentation, unions have either to prioritize their core constituencies and to seek compromises with management, or to adopt inclusive strategies towards peripheral workers to counterbalance eroding bargaining power. This article shows that both strategies represent equally viable options to protect the interests of unions' core members. The strategic choice depends on the (perceived) competition between core and peripheral employees related to employers' personnel strategies; this affects the possible alignment of interests between unions' core members, on the one hand, and either management or peripheral employees, on the other. Our historical analysis of union strategies towards agency workers in the German metal sector illustrates this mechanism, and identifies institutional change towards liberalization as the trigger for aggressive segmentation strategies by employers and for inclusive union strategies.     

Exploring the Critical Potential of the Borderscapes Concept

The conceptual evolution of borders has been characterised by important changes in the last twenty years. After the processual shift of the 1990s (from border to bordering), in recent years there has been increasing concern about the need to critically question the current state of the debate on the concept of borders. Within this framework, this article explores the critical potential of the borderscapes concept for the development of alternative approaches to borders along three main axes of reflection that, though interrelated, can be analytically distinguished as: epistemological, ontological and methodological. Such approaches show the significant potential of borderscapes for future advances of critical border studies in the era of globalisation and transnational flows, thereby contributing to the liberation of (geo)political imagination from the burden of the ‘territorialist imperative’ and to the understanding of new forms of belonging and becoming that are worth being investigated.     

THE GINI CONCENTRATION INDEX: A REVIEW OF THE INFERENCE LITERATURE

More than a century ago, Corrado Gini proposed his well-known concentration index for measuring the degree of inequality in the distribution of income and wealth. His index is still extremely relevant and widely used in several fields of research and application. In this paper, we focus on the inferential properties of the Gini index, and discuss the main directions of analysis proposed in the literature. The aim of the paper is to provide a comprehensive review of the main developments on the inferential aspects of the Gini concentration ratio. We feel that this work can provide a valuable contribution to those scholars who are approaching the large amount of literature on the inferential properties of the Gini index.     

Institutions and Firms' Productivity: Evidence from Electricity Distribution in the EU

Firms' productivity is influenced by internal and external institutions. Ownership is the core internal institutional feature of the firm, while the most important external institutional feature is the quality of government, which shapes the environment in which firms operate. We explore the relative role of these factors and their interaction in determining total factor productivity of electricity distribution firms in 16 EU countries. Using data from the Amadeus database of balance‐sheet information and from the Quality of Governance database, we find that when the quality of government is poor, public ownership is associated with lower productivity levels; however, public ownership is associated with higher productivity in countries characterized by higher quality of the institutional environment.
