Data from the United States Census confirm a substantial increase in the racial earnings gap between 1980 and 1990. This paper examines data on whites and non-white wage and salary incomes in Houston TX for 1980 and 1990. Data on time travelled to work is used to simulate what would be the impact of shorter commute times on earnings inequality. The central finding is that a reduction in travel time from residence to work would cause a very small reduction in racial earnings and income inequality. This suggests that advances in urban transportation policy alone are not sufficient to solve the problem of racial earnings inequality.  相似文献

This study provides an empirical analysis of the market for some male prostitution services in the UK. Flexible working hours, part-time working, and multiple job holding are considered as important labour market characteristics in this service sector. Statistical models helping explain the provision of a deviant and a more mainstream sexual service is reported, utilizing cross-section data drawn from individual prostitute advertisements. The significance of various declared intrinsic endowments of the prostitutes are examined in relation to the offer of these services, including age, ethnicity, physique, and masculine demeanour.  相似文献

An econometric analysis of attendances at Rugby Footbal League matches, in England, over the period 1966–1990 is presented. The major finding is that the move from one to two leagues, in 1973, had a substantial impact on attendances. Teams in the upper league experienced greater attendances ceteris paribuswhilst those in the lower league had reduced attendances.  相似文献

Zusammenfassung Eine Datensammlung über den internationalen Waffenhandel der bedeutenden westlichen Industrie- und Entwicklungsl?nder im Jahre 1980: Quellen und methodische Fragen. — Dieser Aufsatz liefert eine Sammlung von Daten über den internationalen Waffenhandel nach Herkunfts- und Bestimmungsl?ndern (-regionen) für die bedeutenden westlichen Industrie- und Entwicklungsl?nder im Jahre 1980. Die Sammlung enth?lt Sch?tzungen über die Aufteilung des internationalen Waffenhandels nach den vier Sektoren: Kriegsschiffe, Milit?rflugzeuge, milit?rische Nachrichtenausrüstungen und milit?rische Güter. Sie ist st?rker disaggregiert als die Quellen, die zur Zeit verfügbar sind, und enth?lt, wo immer m?glich, Sch?tzungen des Umfanges und der Richtung von Waffenlieferungen.
Résumé Quelques données sur le commerce international d’armes des principaux pays industriels de l’ouest et des pays en voie de développement en 1980: sources et méthodes. — L’intention de l’étude est de représenter des données sur le commerce international d’armes par pays/région d’origine et de destination parmi les principaux pays industriels de l’ouest et les pays en voie de développement en 1980. Les données contiennent des estimations de la répartition du commerce militaire en quatre secteurs: les navires de guerre, les avions de combat, l’équipement de communication militaire et les biens militaires. Les données sont plus désagrégées que celles qui sont disponibles jusqu’à présent et contiennent, s’il est possible, des estimations du volume et de la direction du commerce international d’armes.

Continued decline for ethnic minorities in the transition?   总被引:1,自引:0,他引:1  
Using three Bulgarian cross‐sectional household surveys from 1986, 1993 and 1997, this essay shows that the mean log wage differential between ethnic Bulgarians and Turks increased from 0.1615 in 1986 to 0.2874 in 1993 and again to 0.4075 by 1997. Bulgarian gains over ethnic Turks in the early transition are related to both changes in the relative returns to skill and changes in the composition of demand for goods and services as the country moved toward a market economy. The Turks began the transition with fewer years of education than the Bulgarians, and began to close the education gap over this time. The Bulgarians, however, were more likely to have obtained more general secondary and university degrees than the ethnic Turks – degrees that, in contrast to technical or vocational degrees, are experiencing increased remuneration in the transition. With more of an asset that has become more valuable, the ethnic Bulgarians improved their relative position.  相似文献

Sports broadcasting has been thrown into turmoil in recent years by technical change. This is likely to continue in the future with the emergence of digital broadcasts. There has been widespread concern over the regulation of broadcasts of sporting events. This paper reviews the grounds for regulation and concludes that there is little case for stronger government intervention.  相似文献

Utilizing a job search framework and survey data on both completed and uncompleted spells of unemployment we present in this paper maximum likelihood estimates of the determinants of re-employment probabilities of young workers in Britain. The model used allows us to examine the importance of state dependency in youth unemployment as well as ethnicity, educational qualifications, and unemployment income. Results suggest that there is strong evidence of negative duration dependence in the transition from unemployment to employment for young workers in Britain.  相似文献

The production technology available to the Canadian beef industry comprises a much broader range than is generally recognized. It includes forest and pasture improvement, new grading standards, cross breeding, performance testing, use of bull and dairy beef, artificial insemination, introduction of new breeds, use of new physiological and nutritional knowledge, environmental control, and others. This article appraises the prospect for Canadian beef production moving onto a new technology base, and combining this technology with competent management and promotion in order to meet the demands for beef in the 1980“s. PERSPECTIVES ET POSSIBILITÉS DE PRODUCTION DU BOEUF AU CANADALa technologie de production à la disposition de l'industrie canadienne du boeuf comprend une gamme beaucoup plus et éndue qu'on le pense en général. Elle comprend ‘amélioration des forêts et des pâturages, les nouvelles normes de classification, le métissage, les assais de rendement, l'usage de la viande de taureaux et de vaches laitières, l'insémination artificieile, l'introduction de nouvelles races, l'utilisation de nouvelles connaissances physiologiques et nutritives, le contrôle écologique et autres. Cet article évalue les perspectives du déplacement de la production canadienne de boeuf à une nouvelle base technologique, et la combinaison de cette technologie à une gestion et promotion compétentes pour répondre à la demande en boeuf au cour des années 1980.  相似文献

Roles, role performance, and radical innovation competences   总被引:1,自引:0,他引:1  
Despite the importance of radical innovations (RI), few firms have the capability to develop such innovations internally; success is increasingly linked with relationships and networks. However, the way(s) in which relationships and networks support RI is less clear. Successfully launching RIs requires the development of four distinctive competences; discovery, incubation, acceleration and commercialization. This paper examines how networks support the development of RIs, focusing on when and how network partners become involved and how their role performances support the development of the four competences. The study context is the automotive industry, which is heavily dependent upon RI and complex interrelationships. Data were collected through in-depth interviews with network participants involved in developing several RIs. Five task-oriented and three network-oriented roles are uncovered and the performance of these roles supports the development of different competences, with some roles being exclusively connected with particular competences and others supporting several competences. Focusing on role performance offers a useful means for distinguishing between acontextual actors, and the activities and resources they bring. In doing so, the paper enhances understanding of the links between network participants, role performances and the development of RI competences, and identifies a number of important implications for theory and practice.  相似文献
