We analyze both theoretically and empirically, the effect of aid volatility and its interaction effect with institutional quality on per capita economic growth. Our theoretical model, in which an aid-recipient government, operating in an institutional environment of some given quality (making choices over the distribution of aid), predicts that a negative effect of aid volatility on growth is mitigated by stronger institutional quality. We use panel data covering the period 1984–2004 for 78 countries to test this theoretical prediction. Using Generalised Methods of Moments (GMM) we find the relationship between growth and aid volatility is significantly negative and depends on institutional quality. Our baseline results are robust to various computations of aid volatility and foreign aid, time periods, sub-samples and additional covariates.  相似文献

The implications of the generational diversity inherent in the fabric of the current workforce have been a topic of much discussion, exploration, and debate among organizational scholars and researchers. What are the leadership implications of this generational diversity, and what forms of leadership can be used constructively to achieve performance outcomes that foster a positive and constructive relationship between generations? We turn to the theoretical developments associated with the Authentic Leadership model to synthesize learning lessons from the theory, research, and practice of authentic leadership. We illustrate how the components of authentic leadership can help in overcoming some of the leadership challenges that result due to the differences between Gen Xers and Gen Yers.  相似文献

Abstract

Recent advances in automotive technology have made fully automated self-driving cars technologically feasible. Despite offering many benefits such as increased safety, improved fuel efficiency, and greater disability access, public support for self-driving cars remains low. While previous studies find that demographic factors such as age and sex influence self-driving car support, limited research has examined variables that are well known to predict public attitudes toward emerging technology. Using self-report data from a quota sample of American adults (N?=?1008), we find that age and sex are not significantly associated with support for self-driving car policies when controlling for these other variables. Instead, significant predictors of support included trust in automotive institutions and regulatory bodies, recognition of self-driving car benefits, positive affect toward self-driving cars, and a greater perception that human-driven cars are riskier than self-driving cars. Importantly, we also find that individualism is negatively associated with support. That is, people who value personal autonomy and limited government regulation may perceive policies encouraging self-driving car use as threatening to their worldviews. Altogether, our results suggest strategies for encouraging greater public support of self-driving vehicles while also forecasting potential barriers as this technology emerges as a fixture in transportation policy.  相似文献

ABSTRACT

It is human nature that personal interactions are often charged with emotions and laden with conflicts. Workplace encounters are not immune from this reality. Despite this, few studies have examined ways to reduce interpersonal conflict in the workplace. This study examines the interpersonal impact of emotion regulation on salesperson relationships with stakeholders. Using structural equation modeling, results of the analysis showed that salesperson's regulation of emotions was negatively related to interpersonal conflict with co-workers as well as with customers; and positively impacted customer-oriented sales behaviors. The results also support the moderating role of selling experience in the relationship between emotion regulation and interpersonal conflict with customers. That is, the negative relationship between regulation and conflict with customers is stronger for salespeople with lower sales experience. These findings put forward important managerial implications with regard to the recruitment and training of sales professionals.  相似文献

ABSTRACT

Addressing urban vulnerability requires an understanding of the underlying determinants of resilience for individuals, households, communities and institutions – to withstand shocks, to adapt and to change. Analysing urban resilience utilises the results of five rounds of the Indicator Development for Surveillance of Urban Emergencies surveys conducted in three informal settlements of Nairobi. Results show a significant deterioration in food security and household hunger in marginalised urban populations, with other deprivations including insecurity, negative coping behaviour and inadequate access to water and sanitation. Within slum populations, there was a significant variation in income and expenditure (p?<?0.05) with lowest income quintiles spending over 100% of their income on food. Significant gender disparities have been shown in lowest income quintiles, with female breadwinners earning 62% compared with male breadwinners (p?<?0.05). Recommendations from this analysis include establishing thresholds for vulnerability and concrete dimensions for measuring resilience that can initiate and guide related interventions.  相似文献

Aims: Examine healthcare costs across chronic kidney disease (CKD) stages for US patients with type 2 diabetes (T2D).

Materials and methods: IQVIA Real World Data Adjudicated Claims linked electronic medical records and insurance claims from January 1, 2012 through March 31, 2017 were used for this retrospective study. Adults diagnosed with T2D and comorbid CKD were included. General linear models incorporating splines were constructed, and information from these regressions were used to inform the relationship between medical costs and CKD. Multivariable analyses controlled for patient characteristics, vital signs, general health, prior medication use, prior visit to specialists, index A1c, and year of index date.

Results: There were 6,645 individuals who met the study criteria. Results generally indicate sharp increases in annual total medical costs and non-drug medical costs in the 1?year post-period for patients with Stage 4 or 5 CKD (estimated glomerular filtration rate [eGFR]?≤?30?mL/min/1.73 m2) with each 1 point reduction in eGFR from 30 associated with an increase of $1,870 in all-cause total medical costs (p?<?0.0001) and $1,805 of all-cause non-drug medical costs (p?<?0.0001). Similarly, each point decline below 30?mL/min was associated annual cost increases of $1,701 for CKD-related total medical costs, $1,695 for CKD-related non-drug medical costs, $173 for diabetes-related medical costs, and $187 for diabetes-related non-drug medical costs (all p?<?0.0001).

Limitations: The investigation included only patients with medical insurance and laboratory test results, and results may not be generalizable to all T2D patients with CKD. The methodology allowed us to determine associations, not causation, and potential confounders, such as duration of diabetes, diet, exercise, or social support, could not be assessed.

Conclusions: Results indicate there are sharp and significant increases in medical costs among T2D patients with Stage 4 and 5 CKD compared to those with earlier stages of CKD.  相似文献

An important issue in global corporate risk management is whether the multinationality of a firm matters in terms of its effect on exchange risk exposure. In this paper, we examine the exchange risk exposure of US firms during 1983–2006, comparing multinational and non-multinational firms and focusing on the role of operational hedging. Since MNCs and non-multinationals differ in size and other characteristics, we construct matched samples of MNCs and non-multinationals based on the propensity score method. We find that the multinationality in fact matters for a firm’s exchange exposure but not in the way usually presumed – the exchange risk exposures are actually smaller and less significant for MNCs than non-multinationals. The results are robust with respect to different samples and model specifications. There is evidence that operational hedging decreases a firm’s exchange risk exposure and increases its stock returns. The effective deployment of operational risk management strategies provides one reason why MNCs may have insignificant exchange risk exposure estimates.  相似文献

A number of studies have reported value discounts for listed companies in countries that provide weak legal protection to minority shareholders. Such studies typically attribute these discounts to the ability, and the well‐documented tendency, of controlling shareholders to extract a disproportionate share of corporate resources for “private benefits.” This tendency and the resulting discounts create a dilemma for those controlling shareholders intent on maximizing value for not just themselves, but all shareholders: How can such controlling shareholders assure their minority shareholders that they will not exploit their power to expropriate resources and so eliminate the discount from their companies' shares? This article investigates the possibility that such discounts can be reduced by appointing boards of directors made up of individuals who are independent of the controlling shareholders. Based on the systematic analysis of some 800 companies representing 22 countries, the authors' recent study reports that corporate values are consistently higher when boards are more independent of controlling shareholders—and that this relationship is especially strong in those countries that afford fewer rights to minority shareholders. What is likely to cause controlling shareholders to appoint more independent directors—a change that, after all, effectively limits the controlling shareholders' power and “degrees of freedom”? The answer provided by the authors is that board independence is most likely to be pursued by companies with controlling shareholders that also have major growth opportunities that must be funded mainly with outside equity.  相似文献
