This article uses matched employer-employee data for the State of Georgia to examine workers' earnings experience through the information technology (IT) sector's employment boom of the mid-1990s and bust in the early 2000s. The results show that even after controlling for pre-boom individual characteristics, transitioning out of the IT sector to a non-IT industry generally resulted in a large wage penalty. However, IT service workers who transitioned to a non-IT industry still fared better than workers who took a non-IT employment path. For IT manufacturing workers, there is no benefit to having been touched by technology, likely because of the nontransferability of manufacturing experience to other industries. 相似文献

Conventional housing price index models assume interperiodparameter stability and typically employ either repeat sales or hedonic methodologies. This paper introduces a method of index construction that combines multiple sales observations with single sale transactions while permitting characteristics prices from hedonic regressions to vary over time. A test for interperiod parameter stability is provided. Each period's data are arranged by location and repeat sales are matched by rows. This construction allows greater use of sample information and acknowledges the unique contribution of repeat sales to the estimation process. It also produces intertemporal error correlations that can be beneficially exploited by the seemingly unrelated regressions (SUH) technique. The paper also demonstrates a significance test for error correlation and discusses the treatment of unequal numbers of observations among index periods. 相似文献

This paper offers an empirical analysis of the relationship between income sharing rules and physician heterogeneity in medical group practices.The economies to group formation associated with risk–sharing, mutual monitoring,and internal referral are served by sharing at least a portion of group income equally. Sharing group income equally is problematic, however, when group members differ in their contribution to group income. Member contributions to group income may differ because of differences in ability, effort, or the price of services across specialty fields. The analysis below is addressed to the question of how income sharing rules in physician groups are affected by variation in member contributions. The analysis finds evidence that heterogeneity in member contributions to group income limits the use of equal income sharing rules in multispecialty groups relative to single specialty groups, and large groups relative to small groups. Nevertheless, 65% of all groups in the survey share at least a pn of group income equally, which broadly suggests that the joint surplus enhancement from risk sharing, mutual monitoring, and internal referral are sufficient to overcome the incentive problems of such rules 相似文献

The relationship between the effective utilization of human resources and successful socioeconomic development in Nigeria is examined. The author argues that Nigeria's current socioeconomic difficulties cannot be blamed on population growth alone, and maintains that "underutilization of human resources; lopsided production and distribution mechanisms; economic depression; and under-developed science and technology system; erratic climatic and agronomic conditions; the illegal exportation of food; [and] corruption and mismanagement of revenue, all constitute forces that simultaneously limit the national capacity to produce more resources for the growing population." 相似文献

"We argue that the postwar baby boom [in the United States] caused substantial fluctuations in both the economic rewards to education and educational attainment over the last 3 decades. If substitutability between young and old workers diminishes with education, the present value of lifetime earnings for a boom cohort is depressed more for highly educated workers, reducing incentives for educational attainment. The opposite is true for pre- and postboom cohorts. The diminishing substitutability hypothesis explains the declines in both the returns to college and college completion rates in the 1970s and predicts a substantial increase in educational attainment for postboomers." 相似文献

"This study surveys the policy issues associated with urbanization following the abolition of the pass laws [in South Africa]. The demographic background is briefly sketched. Using neo-classical analysis as a starting point, particular attention is paid to the present inefficiencies of city form associated with segregation. It is argued that current planning procedures are in danger of perpetuating or even worsening the situation. Obstacles to employment generation are considered and transport, local government and housing issues are discussed. On every front, urbanization policy is unstable and, even in the short term, there will be pressures to change it." 相似文献

In an effort to govern their increasingly complex organizations, chief executives in some of today's largest corporations are turning to one of the world's oldest political philosophies-federalism. Given that organizations are seen more and more as minisocieties, the prospect of applying political principles to management makes a great deal of sense. Federalism is particularly appropriate because it offers a well-recognized system for dealing with paradoxes of power and control: the need to make things big by keeping them small; to encourage autonomy but within bounds; and to combine variety and shared purpose, individuality and partnership, local and global. As London Business School professor Charles Handy explains it, federalism responds to these paradoxes by balancing power among those in the center of the organization, those in the centers of expertise, and those in the center of the action--the operating businesses. The centers of federal organizations meet regularly, but they do not need to live together. Doing so would concentrate too much power in one place, whereas federalism gets its strength and energy from spreading responsibility across many decision points. Guided by five principles, federalism avoids the risks of autocracy and the overcontrol of a central bureaucracy. It ensures a measure of democracy and creates a "dispersed center" that is more a network than a place. That's why Asea Brown Boveri CEO Percy Barnevik calls his sprawling "multi-domestic" enterprise of 1,100 separate companies and 210,000 employees a federation. It succeeds because the independent bits, be they individuals, clusters, or business units, know they are part of the greater whole. 相似文献
