The use of visual warnings in social marketing: The case of tobacco

Despite strong interest on the part of tobacco health practitioners, the effect of graphic warnings inserted on cigarette packs is unclear on several levels. First, the most effective themes for such messages have not been clearly identified by researchers. Second, no research has identified the ideal combination of self-efficacy and fear appeal warnings that should be inserted on cigarette packs, according to Protection Motivation Model principles. The exploratory study we conducted with French consumers to test the effectiveness of new graphic warnings proposed by the European Union in 2004 clearly demonstrates that visual messages, as opposed to text warnings, are more effective. This study also enabled us to identify the most effective themes of the European set: health warnings and social messages. Regarding future public health applications, if fear appeals are used, they need to be combined with self-efficacy and cessation support messages since they provoke avoidance reactions.     

Relative Effects of IFRS Adoption and IFRS Convergence on Financial Statement Comparability

One of the primary objectives of both adoption of IFRS and convergence between IFRS and U.S. GAAP is to increase financial statement comparability. Using a unique setting in Germany, we compare the effectiveness of these two approaches in achieving this desired outcome. Our empirical tests show that both adoption and convergence lead to an increase in comparability after the new enforcement regulation in 2005. However, difference‐in‐differences tests show that adoption does not lead to a significant incremental increase in comparability beyond convergence. The findings of this study should be of interest to regulators and standard setters as they assess alternative methods of aligning domestic standards with IFRS.     

Exchange rate undervaluation and manufactured exports: A deliberate strategy?

Recent literature suggests that a proactive exchange rate policy in accordance with price incentives (i.e. undervaluation) can foster manufactured exports and growth. This paper is built on these recent developments and investigates, using a sample of 52 developing countries, whether such a proactive exchange rate policy is adopted. The results show that during the period 1991–2005 a number of countries has used undervaluation to foster the price competitiveness of manufactured exports.     

Can contracts solve the hold-up problem? Experimental evidence

In the contract-theoretic literature, there is a vital debate about whether contracts can mitigate the hold-up problem, in particular when renegotiation cannot be prevented. Ultimately, this question has to be answered empirically. As a first step, we have conducted a laboratory experiment with 960 participants. We consider investments that directly benefit the non-investing party. While according to standard theory, contracting would be useless if renegotiation cannot be ruled out, we find that option contracts significantly improve investment incentives compared to a no-contract treatment. This finding might be attributed to Hart and Moore?s (2008) recent idea that contracts can serve as reference points.     

A NOTE ON SEMIPARAMETRIC ESTIMATION OF FINITE MIXTURES OF DISCRETE CHOICE MODELS WITH APPLICATION TO GAME THEORETIC MODELS*

We view a game abstractly as a semiparametric mixture distribution and study the semiparametric efficiency bound of this model. Our results suggest that a key issue for inference is the number of equilibria compared to the number of outcomes. If the number of equilibria is sufficiently large compared to the number of outcomes, root‐n consistent estimation of the model will not be possible. We also provide a simple estimator in the case when the efficiency bound is strictly above zero.     

Strategic Debt in Vertical Relations: Evidence from Franchising

In this paper, we examine the strategic use of debt in franchise organizations. We focus on both the franchisee's and the franchisor's capital structures. The primary goal of this study is to examine whether franchisors impose limits on franchisees’ debt levels to be able to increase their own leverage. We find that the franchisor's leverage is significantly related to the maximum leverage allowed for the franchisee. As the franchisor sets an upper limit on the franchisee's debt ratio, the franchisor can raise more debt and therefore seizes tax benefits, since interest payments are tax deductible. We find that this effect is stronger in chains with larger fractions of franchised outlets.     

Corporate Codes of Conduct: The Effects of Code Content and Quality on Ethical Performance

Corporate codes of conduct are a practical corporate social responsibility (CSR) instrument commonly used to govern employee behavior and establish a socially responsible organizational culture. The effectiveness of these codes has been widely discussed on theoretical grounds and empirically tested in numerous previous reports that directly compare companies with and without codes of conduct. Empirical research has yielded inconsistent results that may be explained by multiple ancillary factors, including the quality of code content and implementation, which are excluded from analyses based solely on the presence or absence of codes. This study investigated the importance of code content in determining code effectiveness by examining the relationship between code of conduct quality and ethical performance. Companies maintaining high quality codes of conduct were significantly more represented among top CSR ranking systems for corporate citizenship, sustainability, ethical behavior, and public perception. Further, a significant relationship was observed between code quality and CSR performance, across a full range of ethical rankings. These findings suggest code quality may play a crucial role in the effectiveness of codes of conduct and their ability to transform organizational cultures. Future research efforts should transcend traditional comparisons based on the presence or absence of ethical codes and begin to examine the essential factors leading to the effective establishment of CSR policies and sustainable business practices in corporate culture.     

Candidate gene studies and the quest for the entrepreneurial gene

Candidate gene studies of human behavior are gaining interest in economics and entrepreneurship research. Performing and interpreting these studies is not straightforward because the selection of candidates influences the interpretation of the results. As an example, Nicolaou et al. (Small Bus Econ 36:151?C155, 2011) report a significant association between a common genetic variant in the DRD3 gene and the tendency to be an entrepreneur. We fail to replicate this finding using a much larger, independent dataset. In addition, we discuss the candidate gene approach and give suggestions to avoid the publication of false positives.
