Absenteeism in higher education has motivated the investigation of its effect on academic performance. This paper examines the effect of implementing an incentive scheme on seminar PPA (prior preparation and attendance) and performance focusing on a cohort of international postgraduate students over two academic years in two conversion economics (quantitative and non-quantitative) modules at a Scottish business school. The results show that the scheme leads to an increase in the class PPA in both modules and in the probability of passing the quantitative module, however academic performance is affected at a lesser extent. 相似文献

This is a first focused examination of age misreporting in military recruitment. We take advantage of an original dataset comprised of New Zealand military personnel records in the Second Boer War matched with birth historical records. First, we find that age misrepresentation is common: about one third of soldiers on our dataset misreport their ages. Second, we find that soldiers the estimated age-specific mean heights do not change significantly when we change from using reported ages to using true ages. Researchers can prioritise the investigation of true ages on those reporting to be 21 or younger. 相似文献

Heightened geopolitical risk has become the new normal. We study the effects of geopolitical risks on cross-border acquisition activity. Using military alliance to proxy for the degree of geopolitical risks, we find that the formation of military alliance between two countries is associated with greater cross-border acquisition flows. Using the recent North Atlantic Treaty Organization enlargements as identification strategy, we find stronger effects of military alliance, especially with defense pacts. One important channel is that military alliance can substitute for target countries’ institutional quality and minimize extreme geopolitical threats faced by acquirers. We find that countries with poor governance and weaker legal enforcement benefit more from military alliance, especially by receiving inbound acquisitions from major military powers. These findings highlight the role of military alliance in the global market for corporate control by reducing geopolitical risks. 相似文献

Our research examines the effect of combat deployments to Iraq and Afghanistan on casualties and combat exposure compensation policy. We use restricted data from the Defense Manpower Data Center (DMDC) and Social Security Administration (SSA) to construct a panel of all US Active Duty service members having served at some point during the years 2001–2012. Casualties disproportionately occur at higher rates among (i) young, white, males, (ii) enlisted personnel, (iii) less educated personnel, and (iv) those in combat job types. Our estimates indicate that overall US military personnel who deployed in an individual year to Iraq or Afghanistan had a 45 per 100,000 higher probability of death than non-deployed military personnel who remained stateside. The increased fatal injury risk of deployed US military personnel is 15 times higher than the national average civilian workplace fatality rate, but roughly equal to the fatal injury risk faced in some of the most dangerous civilian occupations. Our estimates suggest a compensating wage differential equal to $861 per month would be appropriate in comparison to the current average of $1238 per month in danger pay provided to US military personnel deployed into combat zones. We recommend a revenue-neutral approach in adjusting the pay structure for military members. For example, the military should consider increasing bonuses or base pay while simultaneously decreasing danger pay by an equivalent amount. Furthermore, it may be beneficial to adjust danger pay by service or job type to reflect fatality risk more accurately. 相似文献
