The social costs of gun ownership: a reply to Hayo,Neumeier, and Westphal

We respond to the new article by Hayo, Neumeier, and Westphal (HNW), which is a critique of our 2006 article. The principal contribution of that article wa     

Efficiency comparison of the Wilcoxon tests in paired and independent survey samples

The efficiency concepts of Bahadur and Pitman are used to compare the Wilcoxon tests in paired and independent survey samples. A comparison through the length of corresponding confidence intervals is also done. Simple conditions characterizing the dominance of a procedure are derived. Statistical tests for checking these conditions are suggested and discussed.

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.     

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.     

Age heaping and numeracy: looking behind the curtain

Age‐heaping‐based numeracy indicators have served as valuable tools to derive basic human capital estimates, especially for periods where other indicators are unavailable. However, the accuracy of individual age statements usually remains unknown, and due to the lack of precise information it can only be assumed that excessive occurrence of multiples of five in age distributions reflects inferior numerical skills. This article addresses this lacuna by identifying 162 individuals in two independent data sources: self‐reported age statements and independently kept records which are based on family heritage books and church registers. This method makes it possible to identify individual misreporting and the degree of accuracy of each individual. Findings show that not everyone who reported a multiple of five was reporting an incorrect age, nor was it the case that everyone who reported an age that was not a multiple of five was reporting an accurate age. The empirical analysis shows that the commonly used binary numeracy indicator is correlated with the observed degree of accuracy in age statements, and that a more sophisticated occupational background reduces this inaccuracy. These results tentatively suggest that the commonly used binary indicator measuring age heaping is a valuable proxy for numerical skills and occupational background in a population.     

Bridging the cultural divide: Trust formation in university–industry research collaborations in the US,Japan, and South Korea

Academia and industry increasingly work together, but this is not always an easy endeavor. In this article we investigate how relational mechanisms facilitate trust formation in university–industry research collaborations (UICs) in three countries and contribute to the understanding of international similarities and differences in UICs by considering institutional factors, specifically, the strength and maturity of UICs in each country. Analyzing survey data of 618 recent UICs in the US, Japan, and South Korea, we identify the activities of innovation champions as a critical trust building mechanism between firms and universities that complements initial trust formation through tie strength, partner reputation, and contractual safeguards. We find that partner reputation and champion behavior are more important for trust formation in South Korea than in the US and Japan, indicating that in ‘emerging UIC countries’ where most firms and universities have little collaboration experience, reputation and the leadership by innovation champions are more important for trust formation in UICs than in ‘advanced UIC countries’ with strong and mature UIC networks. From a public policy perspective, our findings suggest that networks between firms and universities should be generally strengthened and collaboration partners should be provided with effective contractual safeguards to enhance trust formation in UICs.     

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.
