Workers earn higher wages in cities vs. rural areas. This gap could arise because cities make workers more productive, or it could be the result of a non-random selection of workers into cities based on their ability and their endogenous history of career choices. To untangle these issues, this paper estimates a dynamic programming model, which embeds the choice of residing in a city or rural area within a model of career choices over time. After controlling for all the sources of selection and endogeneity, the estimates indicate that a given worker does earn more in the city for white-collar work, but not for blue-collar work. In addition, city work experience is found to be worth more than rural work experience in the rural area for white-collar work, but not for blue-collar work. These results support the interpretation that cities make white-collar workers more productive and suggest that workers may consider moving to the city not only in terms of locational choice, but also as a form of human capital investment. 相似文献

Changes in exporter market shares in the Kuwaiti poultry import market over the period 1971–81 are analysed by three modelling procedures. Two traditional approaches, a first-order constant transition probability Markov model and a set of market share equations, are found to be of only limited use. As an alternative, a multinominal logit model of market share behaviour is estimated. The empirical results indicate that, in addition to relative price changes, domestic policy inducements for Brazilian and European Community exports are important in determining market share changes. A comparison of the explanatory abilities of the models suggests that the multinominal logit model is as least as good as traditional modelling alternatives with respect to econometric criteria. It is concluded that the multinominal logit model offers considerable promise as a tool for market share research. 相似文献

Alfred E. Kahn was an observer and practitioner of telecommunications regulation as technology changed the industry from a natural monopoly to a platform-based oligopoly among telephone, cable, satellite, and wireless carriers. Regulation and legislation were slow to recognize these changes, and large welfare losses occurred, some of which could have been avoided if regulators, legislators and economists had followed Fred’s economic advice: Prices must be informed by costs; the relevant costs are actual incremental costs; costs and prices are an outcome of a Schumpeterian competitive process, not the starting point; excluding firms from markets is fundamentally anticompetitive; a reliance on imperfect markets subject to antitrust law is preferable to necessarily imperfect regulation; and a regulatory transition to deregulation entails propensities to micromanage the process to generate preferred outcomes, visible competitors, and expedient price reductions. 相似文献

Independent director death and CEO acquisitiveness: Build an empire or pursue a quiet life? 下载免费PDF全文
Research summary : This study examines the relationship between an independent director's death and CEO acquisitiveness. Using a sample of large U.S. public firms, we find that CEOs who have experienced an independent director's death undertake fewer acquisitions in the post‐director death period, in particular fewer large acquisitions. Our findings are consistent with the prediction of posttraumatic growth theory that mortality awareness can induce CEOs to reevaluate their life priorities and reduce the importance of extrinsic goals in their decision making. This study contributes to the strategic leadership literature by highlighting the influence of the death of CEOs ' social peers on CEOs ' strategic decisions . Managerial summary : Does the death of CEOs ' social peers influence CEOs ' strategic decisions? We find that CEOs who have experienced an independent director's death engage in fewer acquisitions in the post‐director death period, in particular fewer large acquisitions. One likely explanation for our findings is that the death of an independent director may heighten CEOs ' mortality awareness, lead the CEOs to pursue a quieter life, and weaken their propensities for undertaking decisions (i.e., acquisitions) that increase their compensation and social status .

This article develops an ethnographic account of the development and history of the British Airways Heritage Centre (BAHC). Responding to several observations throughout the literature, we report on our experiences of engagement with British Airways’ archives over a 25-year period. In doing so our focus is on the much-neglected history of archives as powerful influences on how corporate histories are written. The ethnographic account is rooted in ANTi-History, an approach to historiography, that focuses on the production of history as knowledge of the past by following a number of human (e.g. archive volunteers) and non-human (e.g. airline artefacts) actors to reassemble the elements that constitute an archive at a point in time. To that end, we trace the inter-relationships between histories of British Airways and the development of the BAHC. We conclude that a focus on the various human and non-human relationships that constitute an archive can help the researcher to identify the hidden influences on the production of history that can otherwise serve to enrol him or her. 相似文献

While research has focused on why certain entrepreneurs elect to create innovative solutions to social problems, very little is known about why some social entrepreneurs choose to scale their solutions while others do not. Research on scaling has generally focused on organizational characteristics often overlooking factors at the individual level that may affect scaling decisions. Drawing on the multidimensional construct of moral intensity, we propose a theoretical model of ethical decision making to explain why a social entrepreneur’s perception of moral intensity of the social problem, coupled with their personal desire for control, can significantly influence scaling decisions. Specifically, we propose that higher levels of perceived moral intensity will positively influence the likelihood of scaling through open as opposed to closed modes in order to achieve greater speed and scope of social impact. However, we also propose this effect will be negatively moderated by a social entrepreneur’s higher levels of desire for control. Our model has implications for research and practice at the interface of ethics and social entrepreneurship. 相似文献

Before 1987, when handheld hair dryers were not required to protect against water immersion electrocutions, there were almost 16 such electrocutions annually in the USA. This article presents a retrospective evaluation of the benefits and costs of the 1987 and 1991 immersion protection requirements of the voluntary hair dryer safety standard in the USA. The benefits are based on estimates of the reduced risk of electrocution resulting from the requirements, and the valuation of the reduced risk derived from willingness to pay studies of the “value of statistical life” found in the economics literature. The costs were defined as the incremental costs associated with incorporating the immersion protection technology into handheld hair dryers. The study found that the requirements were highly effective and may have reduced the immersion-related mortality rate by almost 97%. The expected present value of the estimated benefits of the requirements amounted to about $4.56 per dryer in 2014 dollars and substantially exceeded the costs of about $2 per dryer. The primary outcome measure, the expected net benefits (i.e., benefits minus costs) of the requirements, amounted to an average of about $2.56 per hair dryer, over the hair dryer’s expected product life. Given sales of about 23 million handheld hair dryers annually, the present value of the expected net benefits associated with 1 year’s production would have amounted to about $58.9 million. A sensitivity analysis showed that the major findings were robust with respect to changes in the underlying parameters of the analysis. The study also discusses the factors leading to a high rate of effectiveness estimated for the immersion protection requirements. 相似文献
