What makes a die-hard entrepreneur? Beyond the ‘employee or entrepreneur’ dichotomy

The article makes three contributions to the economics literature on entrepreneurship. We offer a new measure of entrepreneurship which accounts for variations in persistence in self-employment and as a result avoids the weakness of approaches which categorise an individual as an entrepreneur by observing their occupation at just one point in their career. We outline an econometric methodology to account for this approach and find, via a statistical test of model selection, that it is superior to probit/logit models, which have dominated the literature. While our results indicate that this existing literature is good at explaining an individual’s propensity to try self-employment, we find that entrepreneurial persistence is determined by a different model and unearth some new insights. Early self-employment encourages entrepreneurial persistence. For men, inheritance encourages persistence, and facilitates initial self-employment. Having a self-employed father as a role model makes sons persist longer. However, somewhat surprisingly, early experience of unemployment does not affect the probability of self-employment, while reducing persistence. The popular ‘unemployment push effect’ is thus rejected in our sample.

新型农村合作医疗的福利效应分析：微观数据的证据

利用2000年和2006年的中国健康与营养调查(CHNS)数据和倍差方法,以参合农民为作用组,非参合农民为对照组,对新型农村合作医疗政策的福利效应作了实证分析。新型农村合作医疗政策增加了医疗服务利用;但新型农村合作医疗政策对净医疗费用(扣除合作医疗补偿后的费用)没有影响。     

Whistle-Blowing for Profit: An Ethical Analysis of the Federal False Claims Act

This paper focuses on the 1986 Amendments to the False Claims Act of 1863, which offers whistle-blowers financial rewards for disclosing fraud committed against the U.S. government. This law provides an opportunity to examine underlying assumptions about the morality of whistle-blowing and to consider the merits of increased reliance on whistle-blowing to protect the public interest. The law seems open to a number of moral objections, most notably that it exerts a morally corrupting influence on whistle-blowers. We answer these objections and argue that the law is not objectionable on these grounds. Since there are no compelling moral objections to the law, it is appropriate and acceptable to judge the law in terms of its economic costs and benefits. We assess the most salient of these and conclude that the benefits outweigh the costs. We suggest that a mechanism similar to the Act should be considered for protecting stockholders’ interests in the private sector. We conclude by making several proposals for improving the existing legislation. The authors' names are listed in alphabetical order. An earlier version of this paper was presented to the Society for Business Ethics August 2004.     

Fitting strategic resources with product-market strategy: Performance implications

Resources, strategy, and performance inter-relationships are central to strategic marketing theory. Strategic resources are key inputs to product-market strategy that form the basis of superior firm performance. However, these inter-relationships are subject to ‘fit’ requirements. This article examines the hypothesis that greater fit between the strategic resources of marketing organizations and product-market strategy encourages superior financial and customer-market performance. This fit is most important to marketing organizations exhibiting either a Defender or Analyzer strategic orientation. No significant relationship is found for fit among Prospectors.     

Multi-attribute Auction and Negotiation for e-Procurement of Logistics

The paper addresses the topic of e-procurement of logistics services and examines how the system that companies adopt to support this task affects the process performance. The system is evaluated in terms of substantive outcomes (e.g., logistics providers’ profits) and other performances related to perceptions and behavioral issues. Specifically, the considered system is characterized by the exchange mechanism that rules the transaction (multi-attribute auction vs. negotiation) and the level of problem complexity. The analysis, conducted via a laboratory experiment, shows that both the exchange mechanism and the problem complexity affect performance. Practical implications, which could help companies design effective e-procurement systems, are discussed.     

Hedonic shopping motivations in collectivistic and individualistic consumer cultures

We reinvestigate what constitutes hedonic customer experiences in collectivistic versus individualistic cultures using four country samples (N=2,336) in Germany and the U.S. as well as Oman and India. Across country samples, intrinsically enjoyable customer experiences are associated with the same underlying hedonic shopping motivations as shown in the original U.S. context. In comparison with individualistic cultures, we find that a hedonic shopping experience in collectivistic cultures is less strongly associated with selforiented gratification shopping, yet more strongly associated with others-oriented role shopping.     

Supply Chain Integrity: A Key to Sustainable Supply Chain Management

As stakeholders continue to increasingly hold firms accountable for environmental and social performance in their supply chains, the importance of understanding how firms can be more sustainable becomes more prescient. Based on the underlying premise of stakeholder theory that business and ethics decisions are intertwined, the current research introduces the concept of supply chain integrity (SCI) to explore how the interdependence of business and ethics decisions can lead to improvements in sustainable supply chain management (SSCM) practices. Exploratory analysis employing secondary data sources in an elastic net (EN) logistic regression provides support for the proposed construct, by providing preliminary empirical evidence that SCI, measured through two subdimensions of structural and moral SCI, can be linked to firm sustainability. The research contributes to the supply chain management literature by: (1) introducing the concept of SCI; (2) performing an exploratory econometric analysis to provide initial validity of the SCI construct; and (3) providing a research agenda to guide further research on the concept of SCI and its role in SSCM.     

Analytical approximations of local‐Heston volatility model and error analysis

This paper studies the expansion of an option price (with bounded Lipschitz payoff) in a stochastic volatility model including a local volatility component. The stochastic volatility is a square root process, which is widely used for modeling the behavior of the variance process (Heston model). The local volatility part is of general form, requiring only appropriate growth and boundedness assumptions. We rigorously establish tight error estimates of our expansions, using Malliavin calculus. The error analysis, which requires a careful treatment because of the lack of weak differentiability of the model, is interesting on its own. Moreover, in the particular case of call–put options, we also provide expansions of the Black–Scholes implied volatility that allow to obtain very simple formulas that are fast to compute compared to the Monte Carlo approach and maintain a very competitive accuracy.
