"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

We consider a country with two factors and two industries, each of which faces technical and price uncertainty. Entrepreneurs choose outputs in order to maximize the expected utility of profits. They also draw factor payments and purchase consumption goods after the uncertainty isresolved. They enter and exit from an industry according to whether participation there increases their expected utility. Within this model, the validity of the propositions of neoclassical trade theory depends on how the entrepreneurs' entry decisions are affected by parameter changes via their roles as risk bearers, consumers and factor owners.  相似文献

The phrase mixed economy of welfare refers to the observation that the provision of public services in western countries frequently involves the participation of other sectors in addition to government. For example, a service may be privately financed and produced but regulated by government, financed by government subsidies or vouchers but produced privately, or produced by a commercial or voluntary organization under contract to government. But such different ways in which government can arrange public service supply by no means exhaust the varieties of arrangements in a mixed economic system. Other examples include alternative institutional arrangements for articulating consumer wants for public services, evaluating consumer satisfaction, and holding the producers of services accountable for their performance.This paper examines the role of official public advisory bodies and private, voluntary associations whose purposes are to improve services to users of U.S. public transportation. At variance with some of the theory of political economy, it is found that the public and private consumer organizations generally enjoy a symbiotic rather than substitute or competitive relationship with one another, and that both kinds of organizations arise and complement each other in addressing the problems of consumers of a government service produced under monopoly conditions.
Die Beteiligung mehrerer Wirtschaftssektoren bei der Versorgung mit öffentlichen Diensten — der Fall der amerikanischen Verbraucher-Agenturen für öffentlichen Nahverkehr
Zusammenfassung Der Ausdruck mixed economy of welfare bezieht sich auf die Beobachtung, daß die Versorgung mit öffentlichen Gütern in westlichen Ländern häufig nicht allein durch den Staat erfolgt. So kann zum Beispiel ein öffentliches Gut privat finanziert und hergestellt werden, aber unter öffentlicher Aufsicht stehen, oder es kann von der öffentlichen Hand bezahlt aber privat produziert werden, oder es kann durch eine kommerzielle oder gemeinnützige Organisation in Absprache mit staatlichen Stellen produziert werden. Ebenso gibt es Fälle, wo öffentlicher und privater Hersteller eines vergleichbaren Gutes verschiedene Marktseggmente versorgen. Beispielsweise stehen in den USA den Bürgern, die mit öffentlichen Schulen unzufrieden sind, private Schulen zur Verfügung.Diese Beispiele zeigen, auf welchen unterschiedlichen Wegen die Versorgung mit öffentlichen Gütern rangiert werden kann. Solche angebotsorientierten Beispiele zeigen aber nur einen Teil der möglichen Sektorverbindungen in einer Mischwirtschaft. Andere Beispiele treffen eher die Nachfrageseite bei öffentlichen Gütern, insbesondere die institutionellen Möglichkeiten für die Artikulation von Verbraucherwünschen hinsichtlich öffentlicher Güter für die Erfassung der Zufriedenheit und dafür, daß die Anbieter öffentlicher Güter für ihr Leistungsniveau einstehen müssen. Solche Beispiele zeigen, daß Einrichtungen wie Kommissionen für öffentliche Dienste, Departements für Konsumentenfragen, Ombudsmänner und eine Vielzahl privater und freiwilliger Organisationen in unterschiedlichster Weise tätig werden, um die Interessen von Bürgern zu schützen, die öffentliche Leistungen in Anspruch nehmen.Der vorliegende Beitrag betrachtet solche Einrichtungen für öffentlichen Nah- und Fernverkehr in den USA. Ebenso wie in England gibt es hier sowohl offizielle öffentliche Beratungsgremien wie auch private freiwillige Einrichtungen, deren Zielsetzung ganz ähnlich sind, nämlich die Leistungen der öffentlichen Verkehrsunternehmungen zu verbessern. Der Beitrag berichtet über die Ergebnisse einer empirischen Studie beider Arten von Gremien und versucht die Rolle beider Arten in einer Mischwirtschaft zu beschreiben. Insbesondere versucht der Beitrag, zu erklären, warum beide Arten von Gremien entstehen, welches Verhältnis sie zu einander und zu den Transportunternehmen haben. Im Gegensatz zu manchen theoretischen Annahmen erwies sich, daß öffentliche und private Verbraucherorganisationen weniger in einem substitutiven oder wettbewerblichen Verhältnis zueinander stehen, sondern eher eine Symbiose miteinander bilden, und daß sich beide Arten von Organisationen häufig bei der Behandlung von Problemen ergänzen.The author is indebted to his former student and research assistant Chester Phillips for carrying out the survey for this paper. He would also like to thank his colleague Richard Silkman for insightful comments and suggestions on the first draft and Beverly Dolinsky of the Permanent Citizens Advisory Committee to the MTA in New York City for the time and information she provided. Finally, the author wants to thank Ken Judge for providing the stimulus to write this paper through the invitation to participate in the 1983 Social Administration Association Conference in Canterbury, England, where this paper was first presented, and Harry Weiner for arranging support to allow attendance at that conference.

Correlation estimates for returns between individual properties are subject to large inherent uncertainties due to limits on the amount of data that is likely to be available for the foreseeable future. After allowance for correlation sampling error, it is impossible to distinguish on an ex ante basis between the risk-reduction capabilities of mean-variance portfolio selection models and naive diversification without regard to property type or geographical location. The naive portfolio diversification strategies of typical institutional real estate portfolio managers are rational responses to limitations on the informational content of statistical analyses of historical real estate data.  相似文献

This study investigates the effectiveness of the Tokyo Stock Exchange (TSE)-traded Japanese 10-year JGB futures contract to hedge portfolios of Japanese bonds of differing maturity and credit quality. The bond portfolios examined are Government, AAA-, and AA-rated Eurobonds with maturities of 2, 3, 5, 7, 10, and 20 years. Consistent with the recent literature, the study employs univariate methods for calculating hedge ratios based on levels, first differences, and percentage change of each series. Out-of-sample forecasting is used to determine the effectiveness of the calculated hedge ratios for each of the bond portfolios and to determine which approach to calculating hedge ratios is the most effective. The results show that this particular futures contract does provide a good hedge, particularly for those bond terms closest to the 10-year term of the contract. There is some evidence, although not strong, that JGBs are better hedged than AAA and AA bonds. Investors should take some caution when using this futures contract to hedge bond portfolios of different maturities and credit ratings.  相似文献

This study examined the process by which individuals become engaged with their jobs by integrating seminal engagement theory. More specifically, we suggest that an individual factor (i.e. autotelic personality) and two contextual factors (i.e. feedback environment, job autonomy) interact to predict work engagement through three critical psychological states – namely availability, meaningfulness, and safety. This moderated mediation framework was tested using a cross section of the US population (n = 284); data were collected at two points in time with 3 months in between. Availability and meaningfulness mediated the relationship between autotelic personality and work engagement. Autotelic personality’s indirect effect on work engagement through meaningfulness and safety was conditional such that the nature of feedback environment’s effect depended on job autonomy level. Theory and practice implications are discussed.  相似文献

We document that contrary to the conventional view, the costs of domestic firms in terms of selling, general and administrative expenses and cost of goods sold increase significantly following exogenous shocks that increase competition, namely material import tariff cuts affecting US manufacturing industries over the period 1974–2005. Incompatible with an agency explanation, the cost increase is more pronounced among firms with higher CEO/insider/board ownership. We further find that the cost increase is more evident among firms with smaller market share and among focused firms. Generally, our results are consistent with the notion of ‘dissipative competition’ discussed in the seminal papers by Tullock.  相似文献

We analyse more than half a million businesses from the Census Bureau’s 2007 Survey of Business Owners with less survivorship and size biases. After controlling for firm- and owner-specific characteristics, we find family businesses generate fewer receipts and less employment and payroll. Family businesses involving a second-generation owner-manager show better performance. On the other hand, those managed by founder-owners show worse performance. These results of all firms, mostly small businesses, are contrary to the previous studies of large public firms. However, for a subsample of 2064 businesses large enough to be listed on a US stock exchange, the results become consistent with the previous large-firm studies.  相似文献

The person–environment fit theory posits that the term “environment” can be defined at different levels. This study delineates two environmental dimensions (strategic and organizational) and empirically examines the potential moderating effects of two strategic factors (intra‐ and inter‐regional diversification) on the relationship between two organizational factors (subsidiary ownership and host‐country experience) and MNE subsidiary staffing composition. The results indicate that strategic and organizational dimensions have impacts on subsidiary staffing composition. This study also finds that the interaction effects between strategic and organizational factors are significant only when there is congruence between demands from different environmental dimensions.  相似文献
