The business of business, not charity. Say eleemosynary its more confusing. Whatever, as long as we don't given 'em any cash. Harv Antione, ‘The Buzz Words of Entrepreneurship’ in Apocryphal Northern Tales This paper investigates the general determinants of corporate charitable donations in Canada and, in particular, the impact of imperfectly-competitive market structure. We utilize a profit-maximizing model and assume that charitable donations occur only if, by performing an advertising/public relations function, they increase revenue; or if, by acting as a fringe benefit, they result in a reduction in wage costs. In this context, because only firms in imperfect markets generate the rents from which donations can be made, we anticipate a positive relationship between donations and a measure of imperfect competition (concentration). The data is a cross-section sample of 38, 3- and 4-digit SIC manufacturing industries pooled for 1976 and 1981. The major findings are that: the results are generally compatible with the predictions of the model; concentration is a significant determinant of donations although non-linear; the cost of giving (the tax rate) is appropriately positive; and there are significant negative relationships for measures of foreign ownership and wage rates. 相似文献

This paper reports the results of estimating a single equation model of an attendance function for British Rugby League over the seasons 1982/83 to 1990/91. The data are panel data covering virtually every team which played in the two division league over the nine year time period. Diagnostic tests indicate that the appropriate model is a semilog random effects model, where the dependent variable is league attendance weighted by population. The major results are as follows: there are significant positive relationships between league attendance and various measures of team success (although the direction of causality is moot), team quality (as proxied by the two divisions) and the economic quality of team location (as proxied by the unemployment rate); but there is no discernible relationship between league attendance and either success in nonleague trophy competitions or measures of exceptional player quality. 相似文献

The interest in agricultural soils as global storage of carbon has increased in recent years, along with the prospect of farmers' participation in payment schemes under the Clean Development Mechanism of the Kyoto protocol. Thus, a better understanding of agricultural practices that can increase soil carbon and enhance the livelihoods of farmers is necessary, particularly in smallholder farming systems of West Africa. This study evaluates different crop management strategies both by their capacity to sequester carbon in agricultural soils and by their contribution to household income. A case study in Wa, Upper West Region of Ghana is used to test 48 different cropping strategies by means of a crop simulation model and a household-level multiple-criteria optimisation model. Each cropping strategy is evaluated after a 20-year simulation period by its capacity to accrue carbon in the soil, by its economic performance at the plot-level, and by its contribution to the farm income with and without carbon payments. A set of best management practices that concomitantly increase soil carbon and farm income are identified and classified by their cost of investment. 相似文献

In recent years, there has been a growing interest in the environmental impacts of trade liberalization. This paper provides further discourse in this area with a study on Indonesia and its trade agreements with Japan (IJEPA) and ASEAN (AFTA). A static global CGE model, known as the Global Trade Analysis Project, was used to project the Indonesian economy to the year 2022, with and without tariff reforms agreed under the agreements. Environmental impacts are assessed using different pollution indicators—air, water and waste. The study suggests that Indonesia would grow rapidly over the period considered with a large deterioration in its environment. Following these, however, the agreements only have a marginal positive impact on Indonesia's output but with a noticeable increase in trade flows and signs of trade diversion. Overall AFTA has a greater impact on the Indonesian economy compared to IJEPA. Similarly, the impact of trade liberalization on the environment is marginal. On the whole, tariff reform is inducing air pollution and reducing water pollution. In conclusion, the study suggests that Indonesia's participation in the AFTA and IJEPA agreements is not likely to bring drastic changes to her economic and environmental performance. 相似文献

This study uses longitudinal data and four different measures of mental health to tease out the impact of psychiatric disorder onsets and recoveries on employment outcomes. Results suggest that developing a mental health problem leads to a significant increase in the probability of transitioning to non-employment, while a recovery increases the probability of return to work among the not employed with a mental health problem. No consistent effect was found on hours worked and earnings. Research and policy attention is needed with respect to early interventions such as job retention programmes to help workers with mental health problems remain employed as well as interventions that may lead to recovery and return to work. More research is needed especially with data and models that can differentiate between the effects of mental health onsets and recoveries on employment exit and return to work transitions. 相似文献

The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares. 相似文献

Factors influencing the uptake of a mechatronics curriculum initiative in five Australian secondary schools 总被引:1,自引:0,他引:1
While the ready-made Lego™ Robotics kits are popular in schools and are used by students at both primary and secondary year
levels, using the Picaxe microcontroller (chip) to create simple electronic devices, including robotic devices is less popular.
The latter imposes an additional challenge as a result of the need to construct the universal board with the chip in it—a
challenge embraced in the cross-disciplinary mechatronics program in this study. This paper reports on how teachers from five
Australian secondary schools put into practice technological pedagogical content knowledge (TPCK) developed from expert-led
workshops and explores factors (intrinsic and extrinsic) that influenced the implementation. The results show that different
strategies were adopted by the schools in implementing the programs. While teacher attitude played an important role in influencing
the program’s success, being able to identify where the program sits within the curriculum and planning around timetable and
facility constraints were also important factors to consider. The research indicated that teachers’ TPCK was most challenged
in non-obvious areas such as diagnosing where faulty soldering joints were. 相似文献

目的:血液透析相关的血流感染是一个严重的公共健康问题,因为加拿大的血液透析病人从1996年到2005翻了一番。本研究目的在于确定加拿大医院血流感染的成本,估算在综合性医院中建立感染控制项目的成本,并进行成本-效益分析。材料与方法:用加拿大医院感染监测项目的数据来估算医院血流感染的发生率。用加拿大健康信息所数据来估算2004年加拿大平均一次血流感染住院的额外成本。建立和维护一个感染控制项目的成本用美国疾病预防与控制中心1985年的成本换算为2004年的加拿大成本来估算。假设感染控制项目能降低医院血流感染病例的20%~30%。结果:2004年的加拿大15278名血液透析病人中估计共有2524人发生血流感染。全年用于治疗血流感染的成本估计为4901万加元。医院血流感染预防和人力资源的总投资成本为815万加元。建立医院感染控制项目后能带来1452万加元的医疗成本节约。效益成本比在1.0:1到1.8:1之间。结论:本研究提供的证据表明,如果医院感染控制项目能降低20%~30%的感染,该项目的经济效益将远超过增加的成本。医院感染控制项目将带来双重效益:节约货币成本的同时改善医疗质量。 相似文献
