We study the importance of economists’ professional situation towards their life satisfaction based on a unique survey of mostly academic economists. On average, economists report to be highly happy with life. Satisfaction is positively related to spending more time on doing research. The lack of a tenured position decreases satisfaction. However, the extent to which the uncertainty created by the tenure system affects satisfaction varies with the contract terms. The effect is stronger if the contract expires in the near future or cannot be extended. Publication success has no effect if it is controlled for academic rank and the contract duration. The finding suggests that publications are rather a means to an end, for example, to acquire a tenured position. While the perceived level of external pressure also has no impact, the perceived change of pressure in recent years is positively related to economists’ life satisfaction. An explanation is that economists have accepted a high level of pressure when entering academia but are not willing to cope with the recent increase. 相似文献

This article describes the preliminary studies of the effect of advertising and promotion on purchases. The British single-source database Adlab has been the basis for this study of advertising and promotion effectiveness. The ST AS measure and logit modelling have been used to estimate the effect of advertising. The results from the two measures have been compared to determine the extent to which the two measures give occasion for the same conclusions. To indicate the accuracy of the two measures, their respective levels of significance have been studied. Two logit models have been estimated; one only includes the effect of TV exposure, while the other also includes the effect of promotions. The results from the two logit models are compared to determine which model gives the most accurate estimate of the effect of advertising. When comparing the results from the STAS measure with the parameter estimates from the second logit model, it is found that these two different measures largely lead to similar conclusions. Suggestions for further research and developments of the models are given. 相似文献

Information technology (IT)-enabled partnerships can unlock previously unattainable value propositions between organizations that have resource, capability, and other asymmetries by allowing larger organizations access to niche and local resources while providing smaller organizations access to enhanced resources and capabilities. However, recent studies have shown that many IT-enabled asymmetric partnerships often fail because the organizations do not effectively manage the involved collaboration risks. Most organizations focus on the strategic aspect of whether partners behave cooperatively or competitively, while paying scant attention to the operational aspect of bringing together partner contributions through coordination. To examine this problem, we report on a case study of two hub-spoke networks that used telemedicine to facilitate expertise sharing and decision making about stroke treatment at emergency departments in rural hospitals (spokes) based on information exchanges with remote neurologists at academic medical centers (hubs). As a result, we contribute to the inter-organizational information systems literature by explaining how organizations in IT-enabled asymmetric partnerships manage collaboration risks. We demonstrate how partners in such relationships perceive and approach strategic cooperation and operational coordination risks differently. We also explain how collaboration interactions change over time as the partners manage risks based on needs and resource endowments. Drawing on these findings, we provide guidance to organizations on how to manage sustainable IT-enabled asymmetric partnerships in general, and telestroke networks in particular. 相似文献

Since the outbreak of the financial and economic crisis, confidence in politicians as well as the economists in their advisory expert panels seems to be at an all-time low. Why do politicians reject science-based advice unless it fits into their political agenda? Are economists misunderstood by politicians and vice versa? The tension between the ideal of evidence-based policy-making and the reality of policy-based evidence-making is hardly a new phenomenon. Therefore, the expectation that Donald Trump, the Brexiteers and European populists will necessarily disappoint their voters because they simply cannot deliver what they have promised is misleading. Experts would be well advised to use the debate on the post-factual era as an impetus to reflect critically on their profession. One opinion expressed in this Zeitgespräch is that the contested societal and political impact of modern economics is due to its restricted scientific self-concept. A more open, pluralistic and transdisciplinary self-definition of economics would strengthen its societal influence. Another contributor ponders the proper incentives to persuade academic economists to provide economic policy advice. Key is the independence of advisory institutions like the German Council of Economic Experts. The selection of people with the best scientific qualifications will ensure the reputation of such institutions. 相似文献

This paper reports findings from a study of 178 farm households from two contrasting areas in the Eastern Highlands of Ethiopia. It examines risk perceptions of smallholder farmers under varying contexts. The study utilized both qualitative and quantitative methods of data collection and analysis. It was hypothesized that human capital and household characteristics and orientation, access to resources, infrastructure, information and environmental factors influence perceptions of risks in different ways. Data reduction for independent variables was done by factor analysis (principal component extraction method). Factor analyses identified factors influencing smallholder farmers' perceptions of sources of risks. Logistic regression analyses were used to study the relationships of identified principal components to perceived frequencies of occurrences and consequences of various sources of risks. Logistic regression analyses revealed that asset endowments, locational settings and livelihood diversification strategies pursued determine smallholders' perceived risks. Key findings from the informal survey point out differentiation in perceptions of causes and sources of risks by different actors. 相似文献
