Productivity enhancement at home via cross‐border acquisitions: The roles of learning and contemporaneous domestic investments

We examine whether ex post domestic productivity gains accrue to firms making cross‐border acquisitions. We argue that cross‐border acquisitions can enhance the acquirers' productivity at home, and we posit that these domestic productivity gains will be greater when there are learning opportunities in the target's host country and when contemporaneous domestic productivity‐enhancing investments are made by the acquirer in conjunction with the acquisition. These predictions are supported by data drawn from a sample of French acquiring and nonacquiring firms. Our results indicate that cross‐border acquisitions and investing in productivity at home are complementary: each makes the other more beneficial to firm productivity.

OECD imports: diversification of suppliers and quality search

We posit that OECD buyers are in a continuous search for best quality suppliers from developing countries. We build a simple model of adverse selection and quality screening which captures this feature. The model predicts that diversification happens by “bouts”, or temporary episodes, during which OECD buyers search for high-quality suppliers. Each diversification episode is followed by a phase of re-concentration on the best performers, until those fail (which happens stochastically), triggering new search phases. The model also shows that concentration across origin is highly volatile, especially for goods with high-quality heterogeneity. Finally, as the set of suppliers expands and buyers continue sampling, the overall trend is an increased diversification across time. We empirical explore these conjectures using OECD imports over time (1963–2006) and measuring their concentration across 250 origin countries at the product level (1,300 products). We provide strong empirical evidence corroborating the model predictions.     

Entrepreneurial intentions, motivations and barriers: Differences among American, Asian and European students

Should entrepreneurship education be the same in every country or should it be adapted to each context? In addition to answering this question, it appears to be important to identify the concerns students have regarding their entrepreneurship education programs, so as to strengthen their perceptions of feasibility and desirability of an entrepreneurial career. In this article we examine whether differences exist among American, Asian and European students in terms of entrepreneurial intentions and dispositions, as well as motivations and perceived barriers for business startup. Results indicate that entrepreneurial disposition and intentions differ by country but that students across countries are motivated and/or discouraged by similar variables. However, our results indicate that the levels of sensitivity to each motivator and barrier differ by country. Our results support the argument made by past researches that cultural differences should be taken into consideration when developing entrepreneurship education programs.     

A theory of tolerance

We propose a theory of tolerance where endogenous lifestyles and exogenous traits are invested with symbolic value by people. Value systems chosen by parents for their children affect the esteem enjoyed by individuals in society. Intolerant individuals attach all symbolic value to a small number of attributes and are irrespectful of people with different ones. Tolerant people have diversified values and respect social alterity. We study the formation of values attached to various types of attributes and identify circumstances under which tolerance spontaneously arises. Policy may affect the evolution of tolerance in distinctive ways, and there may be efficiency as well as equity reasons to promote tolerance. An empirical investigation of tolerance of homosexuality demonstrates that our theory helps to shed light on survey data of endorsed values.     

Hedging under counterparty credit uncertainty

This study investigates optimal production and hedging decisions for firms facing price risk that can be hedged with vulnerable contracts, i.e., exposed to nonhedgeable endogenous counterparty credit risk. When vulnerable forward contracts are the only hedging instruments available, the firm's optimal level of production is lower than without credit risk. Under plausible conditions on the stochastic dependence between the commodity price and the counterparty's assets, the firm does not sell its entire production on the vulnerable forward market. When options on forward contracts are also available, the optimal hedging strategy requires a long put position. This provides a new rationale for the hedging role of options in the over‐the‐counter markets exposed to counterparty credit risk. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28: 248–263, 2008     

How persuasive is ‘free’ public transport?: A survey among commuters in the Brussels Capital Region

In Belgium, several cities have been experimenting with ‘free’ public transport based on the concept of a third payer system. This study explores the modal shift potential of this measure for commuters by means of a large-scale survey. The results indicate that there is still a margin for a further modal shift, but in order to make public transport more attractive to car users, the price paid by the commuter should be lowered, the quality and capacity of the public services should be improved and the mobility policy of the companies should be adjusted in favour of public transport.     

Folksonomies: Spontaneous crowd sourcing with online early detection potential?

This article focuses on the analysis of this distributed, heterogeneous, open and continuous production of “data about data” and its possible contribution to early detection objectives. It assesses whether the related processes of open classification and free annotation could provide promising results not only for information retrieval goals, which they are meant for, but also for detecting weak signals of incoming changes.     

Nonparametric Tests for Positive Quadrant Dependence

We consider distributional free inference to test for positivequadrant dependence, that is, for the probability that two variablesare simultaneously small (or large) being at least as greatas it would be were they dependent. Tests for its generalizationto higher dimensions, namely positive orthant dependence, arealso analyzed. We propose two types of testing procedures. Thefirst procedure is based on the specification of the dependenceconcepts in terms of distribution functions, while the secondprocedure exploits the copula representation. For each specification,a distance test and an intersection-union test for inequalityconstraints are developed for time-dependent data. An empiricalillustration is given for U.S. insurance claim data, where wediscuss practical implications for the design of reinsurancetreaties. Another application concerns detection of positivequadrant dependence between the HFR and CSFB/Tremont marketneutral hedge fund indices and the S&P 500 index.
