This article offers a critical assessment of the “survivor bonds” (SBs) proposal recently put forward by Blake and Burrows, which calls for the government to issue bonds whose coupon payments are contingent on the proportions of retirees surviving to particular ages. It suggests that the proposal has considerable merit and discusses the circumstances in which SBs would be useful risk management tools for insurance companies. It also discusses alternatives such as reinsurance, hedging with life contracts, dynamic hedging, and other forms of survivor derivative. Finally, it evaluates and rejects the argument that SBs should be issued by the state. 相似文献

This paper examines the potential impact of the 1986 U.K. Insolvency and Company Directors' Disqualification Acts on small firm financing decisions. With the aid of a simplified Black and Scholes (1973) option model of financing decisions, the paper illustrates how the 1986 legislation reduces the incentives for owner-managers to gamble with creditor claims, particularly in situations of financial distress, by making them personally liable for unmet claims and/or by disqualifying them from holding office for a fixed period. For instance, example 3 in the paper shows the conflict that could result from the owner-manager reducing his/her opening equity position and it further argues how the legislation should act to alleviate the situation. It remains, however, an empirical question as to whether this reduction in creditors' exposure to the risk of uncompensated wealth transfers will ultimately result in a significantly greater number of company liquidations and disqualifications, particularly during a prolonged economic downturn, or an improved/less costly supply of finance to small firms. 相似文献

Several papers have been published demonstrating the positive effects a single, reputable ally has on evaluations of a focal brand. Interestingly, little research has been published examining the effects of multiple brand allies. We examine the effect of an alliance with two, one, or zero well-known brand allies on evaluations of a previously unknown focal brand. The presence of a single brand ally significantly increased perceived quality and hedonic and utilitarian attitudes. While multiple alliances improved focal brand evaluations relative to the no ally condition, the second ally did not increase evaluations relative to the single ally condition. 相似文献

This article deals with the prediction problem in linear regression where the measurements are obtained using k different devices or collected from k different independent sources. For the case of k=2, a Graybill-Deal type combined estimtor for the regression parameters is shown to dominate the individual least squares
estimators under the covariance criterion. Two predictors ŷ
c and ŷ
p are proposed. ŷ
c is based on a combined estimator of the regression coefficient vector, and ŷ
p is obtained by combining the individual predictors from different models. Prediction mean square errors of both predictors
are derived. It is shown that the predictor ŷ
p is better than the individual predictors for k≥2 and the predictor ŷ
c is better than the individual predictors for k=2. Numerical comparison between ŷ
c and ŷ
p shows that the former is superior to the latter for the case k=2. 相似文献

This article examines the impact of regulation and market-driven private actions on food safety performance in the meat and poultry industries. We find that private actions account for about 80% and regulation about 20% of the overall reduction in the share of samples of cattle and hog carcasses, ground beef, and broilers testing positive for Salmonella if all regulation and private actions were increased by identical amounts. 相似文献

Data from the AICPA (2009b) show that African–Americans comprise only 1% of CPAs and were only 4% of new hires by CPA firms in academic year 2007–2008. The current study uses social cognitive career theory to examine whether this shortage of diversity may be caused by differences between African–American and Caucasian students in factors that lead to career interest in accounting. Students were surveyed on two key personal variables: self-efficacy and outcome expectations. Results suggest that African–American students are more likely than Caucasian students to perceive accounting as providing outcomes that match their values. However, favorable perceptions may be countered by differences in self-efficacy. African–American students value outcomes provided by accounting, but they may have less confidence, compared to Caucasian students, that they can successfully complete the course of action necessary to enter the profession. 相似文献

This paper presents an empirical investigation of the productivity effects of UK management buyouts (MBOs) over the period 1986–1997. It is the first study to use an augmented production function approach in order to determine and quantify: the Hicks–neutral productivity, the marginal productivity of labour, and the marginal productivity of capital effects of MBOs. The main findings are consistent with MBOs providing incentive and control systems that lead to improved firm–level productivity in the post–buyout organisation via reduced agency costs, debt bonding, and monitoring by buyout specialists. 相似文献

The United States (US) exports more than US$6 billion in agricultural commodities to the European Union(EU) each year, but one issue carries the potential to diminish this trade: use of biotechnology in food production. The EU has adopted more stringent policies towards biotechnology than the US. Understanding differences in European and American policies towards genetically modified (GM) foods requires a greater understanding of consumers’ attitudes and preferences. This paper reports results from the first large‐scale, cross‐Atlantic study to analyse consumer demand for genetically modified food in a non‐hypothetical market environment. We strongly reject the frequent if convenient assumption in trade theory that consumer preferences are identical across countries: the median level of compensation demanded by English and French consumers to consume a GM food is found to be more than twice that in any of the US locations. Results have important implications for trade theory, which typically focuses on differences in specialization, comparative advantage and factor endowments across countries, and for on‐going trade disputes at the World Trade Organization. 相似文献
