Khat-chewing in liminal leisure spaces: British-Somali youth on the margins

Khat-chewing, a controversial leisure activity within the Somali diaspora in Britain, has received little attention within the academic field of Leisure Studies. This paper reports on ethnographic research to provide insights into the unique locations where young British-Somali men chew khat, exposing the liminal qualities of such localities. The paper begins with an overview of the contentious position khat-chewing occupies within Somali communities in Britain, highlighting reasons why young British-Somali men hide their association with the leisure practice. The discussion that follows considers how young male khat users conceptualise spatial environments, exposing how these locations temporarily produce a dual sense of privacy and sociality. The ambiences of such temporary leisure spaces remain open to the prospect of discovery, resulting in the use of discretionary tactics to maintain a sense of secrecy. In this context, we discuss how khat-chewing offers a sense of cultural identity and belongingness while also marking young British-Somali men as outsiders – even within their own communities.     

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.     

Third-party certification and post-IPO acquisitions

ABSTRACT

We explore the link between third-party certification (venture capital backing, analyst following and having a top underwriter), and post-IPO acquisition activity through the reduction in valuation uncertainty channel. In a sample of 2,424 U.S. IPOs, we find that third-party certification facilitates post-IPO acquisitions. The certified firms are both more likely and conduct acquisitions sooner after the IPO. Our results support the notion that third-party certification reduces post-IPO valuation uncertainty and thereby facilitates a more efficient acquisition strategy.     

Confronting the implications of the Cournot model with industry and firm data

This paper derives testable implications of the standard Cournot models and confronts these implications with real world data. Though we cannot expect that real world may be characterized by a simple static homogeneous model, it is surprising that little empirical work exists on testing the implications of this most popular model of oligopoly and non cooperative game theory.We make use of three data sets for manufacturing industry, two of them on the firm level, one about firms grouped according to their size. The relation of the results to the predictions of the Cournot model is discussed, as well as its relation to alternative oligopoly models. We specifically focus at the question whether the implications of the oligopoly models on the performance of large versus small firms are in line with the data.     

Revisiting an Evasive Concept: Introduction to the Special Issue on Competitiveness

The term competitiveness stems from the analysis of firms and is usually thought to be well defined at the firm level. Today, however, the notion competitiveness has become a prominent concept in the assessment of countries, regions and locations. The competitive advantage of nations and the competitiveness of locations have become important topics in economic policy. Interest in this field has been notably stimulated by the work of Michael Porter. Although the diversity of approaches presented in this issue may appear large to the reader, it is in reality dwarfed by the multiplicity of concepts, articles and books which have been written in reference to the term competitiveness. The vagueness of the general term, the lack of theoretical background, implicit preferences and prejudices, and finally the scope of policy recommendations made in reference to this term have induced outstanding researchers to warn that the term competitiveness of a nation could be dangerous, obsessive, elusive or meaningless.¹ The articles presented in this volume share some elements of this critique, but also demonstrate that research is being continued, and that it is indeed relevant to the design and evaluation of economic policy, most notably, the so-called Lisbon Strategy of the European Union.     

Der EU-Haushaltskompromiss vor dem Hintergrund der Gemeinsamen Agrarpolitik

Dem Kompromiss über die EU-Haushaltsplanung für die Jahre 2007 bis 2013 war eine kontroverse Debatte über den Umfang des „Briten-Rabatts“ und die Gemeinsame Agrarpolitik vorausgegangen. Welche Bedeutung hat die Agrarpolitik für die EU? Welche Mitgliedstaaten geh?ren im EU-Haushalt zu den Nettozahlern? Besteht ein Zusammenhang zwischen den Zahlungsstr?men aus dem EU-Haushalt und der Wohlstandsverteilung innerhalb der EU?     

Der Flexibilitätsbeitrag in der Arbeitslosenversicherung

The controversy around fixed-term contracts centres around the conflict between the employer’s need for flexibility and the employee’s need for security. The authors propose flexible contributions for employers to the public unemployment insurance system to balance both interests. The employers’ contributions for their temporary staff would increase while the contributions for their permanent staff would in turn decrease slightly. The authors calculate four versions. With regards to the total sum of contributions, the first version holds the contributions received constant while the second version leads to a reduction. They then repeat these two calculations for fixed-term contracts without substantive grounds. The flexibility premium takes into account the higher unemployment risk of employees with fixed-term contracts and establishes monetary incentives for employers to hire employees with permanent contracts.
