This article investigates theoretically and empirically theeffects of competition for donors on the behavior of nonprofitorganizations. Theoretically, we consider a situation in whichnonprofit organizations use donations to produce some commodity,but the use of donations is only partially contractible. Themain results of the model indicate that an increase in competition(i) decreases the fraction of donations allocated to perquisiteconsumption and (ii) increases the fraction of donations allocatedto promotional expenditures. Moreover, the effects of competitionare magnified by the ability to contract on the use of donations.These hypotheses are tested with data on the expenditures ofnonprofit organizations in a number of subsectors where competitionis primarily local. We use across–metropolitan statisticalareas' variation to measure differences in competition and proxycontractibility by the importance of tangible assets, whichare more easily observed by donors. The estimated effects ofcompetition and contractibility are consistent with our model. 相似文献

We examine potential information transfers from companies that announce dividend omissions to their industry rivals. Specifically, we examine the abnormal stock returns and abnormal earnings forecast revisions of rivals after a company makes a dividend‐omission announcement. Our results show negative and significant abnormal stock returns and negative and significant abnormal forecast revisions for rival companies in response to the announcement, and a significant and positive relation between the two. We conclude that a dividend‐omission announcement transmits unfavorable information across the announcing company's industry that affects cash flow expectations and ultimately stock prices. 相似文献

Private charities often publicise generous individual contributions or contributors, possibly to encourage others to give. In contrast, public good experiments used to study voluntary giving commonly tell participants only of total contributions. This paper reports an experimental test of the effect on contributions of supplying additional selective information. A control treatment is run that reveals only total contributions over ten one‐shot decision rounds. This is compared to a second treatment that also informs subjects of the maximum contribution made in their group after each round. In a third treatment, subjects are further given the opportunity to make costly rewards to the maximum contributor. Revealing generous contributions appears to raise average contributions slightly. Surprisingly, adding the ability to reward large contributors does little to generate further increases, though it significantly raises the variance of contributions.

The paper explores the specific challenges facing the pharmaceutical industry regarding the exploitation of information and communication technologies (ICTs) in the context of developing new frameworks supporting knowledge activity and the wider innovation process. The paper seeks to provide a framework to view these changes but also highlights gaps in our current conceptualization of the role of ICTs in facilitating and effecting change within the pharmaceutical industry. 相似文献

Tacit knowledge 总被引:1,自引:0,他引:1
Jeremy Howells 《Technology Analysis & Strategic Management》1996,8(2):91-106
Until recently, the concept of tacit knowledge has been neglected by academics and managers alike, but this has now changed as lacit know-how has become recognized as palying a key role in firm growth and economic competitivenss. Tacit knowledge forms an important element in a firm's knowledge base and has a central role in organizational learning. This analysis stresses the need to view tacit knowledge in a dynamic setting, and that tacit knowledge can be acquired and transferred on a variety of levels: individual, group, firm and inter-firm basis. The paper then explores the policy implications of technology transfer initiatives which seek of shift tacit know-how between firms and analyzes the ways that this can be achieved. 相似文献

This paper describes the frameworks and cognitive tools that have been developed to enhance practising teachers' pedagogical
content knowledge in primary school technology education. The frameworks evolved from our research that firstly examined existing
teaching practices, secondly enhanced formative interactions and thirdly enhanced summative assessment strategies. The evidence
gained over the three years demonstrated how the effective use of frameworks could be utilised to enhance teacher pedagogical
content knowledge (PCK). How we see learning is of prime importance in examining the development of teacher pedagogical content
knowledge. A sociocultural view of learning is taken where human mental processes are situated within their historical, cultural
and institutional setting. In the research project we strongly emphasised the need for teachers to build a knowledge base
for teaching technology. Critical aspects identified as enhancing PCK included: negotiated intervention, planning frameworks,
reflection on case studies, workshops and support in classrooms, appropriate resources, teacher agreement meetings, portfolios
of student work and summative profiles. The increased PCK resulted in: enhanced teacher knowledge about technology including
the nature of technology, areas of technology and specific technological knowledge, changed pedagogical approaches, enhanced
teacher student interaction, refinement of appropriate learning outcomes, critical decision making, improved teacher confidence,
and enhanced student learning. Seven characteristics or features of pedagogical content knowledge that we believe are important
for effective teaching and learning in technology are presented.

Most studies on climate change response have examined reductions in greenhouse gas (GHG) emissions. Yet these studies do not
take into account ecosystem services constraints and biophysical disruptions wrought by climate change that may require broader
types of response. By studying a firm in the wine industry and using a research approach not constrained by structured methodologies
or biased toward GHG emissions, the findings suggest that both “inside out” and “outside in” actions are taken in response
to climate change. While attempts are made by the firm to curtail and reverse climate change through management of carbon
emissions, evidence suggests a clear pattern of actions designed to adjust to the adverse consequences of climate change as
well. The results both confirm and extend previous findings and suggest that the level and breadth of response to climate
change is shaped by situated attention, structural controls, and industry type. 相似文献

Specialization,diversification, and productivity: a panel data analysis of rice farms in Korea 总被引:1,自引:0,他引:1

This article examines the microeconomics of productivity associated with specialization/diversification in production activities, with an application to Korean rice farms. Korean rice farms tend to be very small and highly specialized. Our analysis examines the productivity effects associated with both farm size and farm specialization/diversification in Korean agriculture. Relying on farm‐level panel data, the analysis studies farm productivity in a multi‐input multi‐output context, accounting not only for changes in inputs and technical change in rice production, but also for the role of diversification in the production of other crops in current and previous periods. We find positive but small productivity gains from farm diversification. These gains come mostly from complementarity effects across farm outputs, with minimal effect of scale economies. The positive complementarity effects work against nonconvexity effects, which provide strong productivity incentives for rice farms to specialize. 相似文献

Past field validity tests of contingent valuation have relied on voluntary contribution mechanisms to elicit actual willingness to pay, and may overestimate hypothetical bias because of free riding in the actual contributions. This paper argues that provision point mechanisms are a preferred alternative for field validity tests of contingent valuation because they increase the proportion of demand revealed in cases in which public goods can be provided in a step function. The results of a contingent valuation validity study of participation in a green electricity pricing program that uses a provision point mechanism are reported, and hypothetical open-ended and dichotomous choice responses are compared to actual participation. Calibration of hypothetical responses is also explored. 相似文献
