Let the evidence speak again! Financial incentives are more effective than we thought

In this essay, the authors rejoin the debate about financial incentive effectiveness. They (a) briefly review the state of the literature in 1998, (b) highlight new meta‐analytic findings and update conclusions regarding the financial incentives–performance relationship, (c) address the myth that financial incentives erode intrinsic motivation, (d) provide explanations for the presumed failure of financial incentives and (e) offer some concluding thoughts and suggestions for future research.     

WTO争端解决机制下药品专利保护案对我国的启示

美诉印度药品和农业化学产品专利保护等案涉及的问题：未公布的行政做法与透明度原则的关系、DSH推理中司法经济原则之运用、不同成员基于同一事由再次申诉、专家组报告作为先例的约束力等，这些对我国有一定启示。结合我国目前药品专利实施情况，应运用公共利益原则，适当延长药品专利保护期；专利保护期将尽时对仿制药品予以保护。     

International trade and child labor: Cross-country evidence

We explore the relationship between exposure to trade (as measured by openness) and child labor in a cross-country setting. Our methodology accounts for the fact that trade flows are endogenous to child labor (and labor standards more generally) by examining the relationship between child labor and variation in trade based on geography. We find that countries that trade more have less child labor. At the cross-country means, the data suggest an openness elasticity of child labor of − 0.7. For low-income countries, the elasticity of child labor with respect to trade with high-income countries is − 0.9. However, these relationships appear to be largely attributable to the positive association between trade and income. We consistently find a small and statistically insignificant association between openness and child labor when we control for cross-country income differences in the full sample, when we split the sample into different country groups, consider only trade between high- and low-income countries, or focus on exports of unskilled-labor intensive products from low-income countries. Thus, the cross-country data do not substantiate assertions that trade per se plays a significant role in perpetuating the high levels of child labor that pervade low-income countries.     

Motivating innovation in newly public firms

Prior research suggests that executive option grants that do not quickly vest provide managers with better incentives to pursue long-term, instead of short-term, objectives. Previous research also suggests that the pursuit of long-term objectives could be undermined by the risk of early termination. We conjecture that these arguments jointly suggest that managers are better motivated to pursue innovation when they are given more incentive compensation with longer vesting periods for unexercised options and yet some protection from disruptive takeover threats. Our evidence for a sample of newly public firms is consistent with more innovative firms jointly choosing such a combination.     

Is Marriage Poisonous? Are Relationships Taxing? An Analysis of the Male Marital Wage Differential in Denmark

Differences in the pattern of marriage, cohabitation, childbirth, and intrahousehold specialization between the United States and Denmark, as well as a rich, register-based panel sample of about 35,000 young Danish men, are exploited to shed light on the nature of the male marital wage differential. The results indicate that failing to control for cohabitation can seriously bias estimates of the marital wage differential, that marriage is a more selective state than cohabitation, and that specialization may explain some of the marital wage differential in the United States but not in Denmark. In Denmark, by contrast, there is evidence that fatherhood has a significant impact on earnings.     

Factors Influencing Successful Brand Extensions

Organisations frequently follow brand extension strategies. This paper investigates the impact of category similarity, brand reputation, perceived risk and consumer innovativeness on the success of brand extensions in FMCG, durable goods and services sectors. A set of hypotheses were developed and tested in a study amongst 701 consumers. The findings show that extensions into categories more similar to the original brand tend to be more readily accepted. Likewise, the reputation of the original brand is an important factor influencing the success of the extension. These findings are consistent across FMCG, durable goods and services brands. However, perceived risk about the extension category was only found to enhance acceptability of extensions for durable goods and services brands. Innovative consumers are more positively disposed towards service brand extensions than FMCG and durable goods brand extensions.
