美国开放式基金产业发展现状及其对我国的启示

通过分析美国基金产业现状发现,美国开放式基金产业是美国普通居民首要的投资渠道。作为金融市场最重要的投资者,开放式基金对塑造现代美国金融结构和竞争环境发挥了重要作用。美国的基金产业发展得益于良好的法律法规和监管机制等基础制度建设,以及较低的准入门槛和金融市场的有序竞争。     

The U.S. Motion Pictures Industry: An Empirical Approach

We hypothesize that the U.S. motion pictures industry is structured so that star presence increases box office receipts and (less so) admissions, but places Ricardian limits on the output of blockbusters. The few dominant studios (majors) rely on a modified star system to generate supra-normal box office by stimulating admissions at exhibitors. Rising costs (from stars and their promotion) are required for rising revenues; that is, the majors gain revenue only at higher costs. Although the industry has unique features, the empirical results are surprisingly relevant to other industries.     

美国纺织工业的兼并浪潮

1998年是美国纺织工业企业兼并重组活动创纪录的一年,并且兼并的步伐似乎不会停止。面对强大的竞争压力,越来越多的公司选择合并或购并其它公司以努力改善其命运。本文透过1998年企业兼并活动,探讨推动     

The Welfare Effect of Advertising Restrictions in the U.S. Cigarette Industry

The welfare effect of advertisingrestrictions in the U.S. cigarette industry dependsupon the impact of advertising on consumer and producer surplus, the transfer to consumers for being exposed to utility-reducing advertising, and smoking externalities. We estimate a demand equation and a supply relation simultaneously and use the parameter estimates to generate predictions of the impact of advertising restrictions on social welfare. Our results show that advertising restrictions benefit producers by limiting competition and generating higher industry profits, and such restrictions lower social welfare if the external cost of cigarette smoking is sufficiently low.     

Competition and Service Quality in the U.S. Airline Industry

The U.S. government, media, and flying public have expressedgreat concern in recent years over both airline market concentration and flightdelays. This study explores potential connections between the two by examining whetherthe lack of competition on a particular route results in worse on-time performance.Analysis of data from the U.S. Bureau of Transportation Statistics in 2000 indicatesthat both the prevalence and duration of flight delays are significantly greater onroutes where only one airline provides direct service. Additional competition iscorrelated with better on-time performance. Weather, congestion, and schedulingdecisions also contribute significantly to explaining flight delays.     

Common Properties and Sectoral Specificities in the Dynamics of U.S. Manufacturing Companies

The size distribution and growth rate dynamics of U.S. companieshave been extensively studied by many authors. In this paper,using the COMPUSTAT database, we extend the analysis todisaggregated data, studying 15 sectors of the U.S.manufacturing industry. The sectoral investigation reveals thepresence of general statistical properties that can be consideredvalid across all the studied sectors. In particular, theprobability density of firms growth rates invariably displays acharacteristic tent shape and the relation between the size of afirm and the variance of its rates of growth is characterized, indifferent sectors, by very similar scaling relations. Thepresence of characteristics that are robust and sectoral invarianthints at the existence of generic statistical properties shapingthe dynamic of firms across the whole industry.     

The Gradual Response of Market Power to Mergers in the U.S. Steel Industry

Studies of the impact of horizontal mergers on market power typically impose an immediate adjustment of market power following a merger. This paper adopts an alternative procedure to estimate the effect of four mergers on market power in the U.S. steel industry. Namely, by estimating a switching regression model that incorporates profit-maximizing behavior, the results show that mergers generally increased market power in the steel industry. However, it did take some time for market power to fully adjust after each merger.     

The Finances of Major U.S. Unions

Financial resources have a significant impact on labor's current attempt to reassert itself. We examine the total assets, net worth, and income of unions in (1) a cross-sectional analysis of the distribution of financial resources across national, intermediate, and local levels of unions and (2) a longitudinal analysis of trends in a variety of financial measures. We observe considerable decentralization of financial resources across levels, substantial concentration of resources, and differences across and within union sectors. These results are discussed with regard to current merger activity.

President-elect Clinton can learn a lot from this continent about health care and how to revitalize cities. But industrial policy is another story.     

U.S. national security export controls: Implications for global competitiveness of U.S. high-tech firms

U.S. exporters of high-technology, ‘dual-use’ products are competitively disadvantaged in global markets by the complexity, range, and stringency of U.S. national security export controls. This paper demonstrates that fungibility of high technology and lax interpretation of multilateral export control agreements by other advanced countries have made the existing control regime ineffective. It further shows that persistent U.S. restrictiveness of exports in non-critical, widely available goods and technologies may needlessly and permanently erode U.S. firms' competitive position in existing as well as rapidly-opening markets worldwide. The need to revise the notion of national security to include not only military security, but also its complement, economic security, is discussed. The pivotal issue of enforceability of multilateral controls is explored, and corporate strategies for U.S. high-tech firms to achieve export control policy change are suggested.     

Industry costs and consolidation: efficiency gains and mergers in the U.S. railroad industry

Since partial deregulation in 1980, there has been a massive consolidation of firms in the U.S. railroad industry premised largely on efficiency gains. We estimate a cost function and use it to calculate cost effects for specific mergers and for all mergers at the industry level from 1983–2003. Our central results are that consolidation in the railroad industry accounts for about an 11.4 percent reduction in industry costs (more than $4 Billion in 1992 prices), and that while there are tremendous differences across mergers with respect to the direction, level, timing, and source of cost impacts, most mergers result in cost savings.     

The evolution of competition in U.S. manufacturing

Although four-digit concentration ratios remained roughly constant in the quarter century between 1958 and 1982, they declined significantly when adjusted for imports. The empirical analysis in this paper shows that changes in both types of four-digit concentration ratios were related to the initial level of industrial concentration, barriers to entry, market growth, and to a set of adjustment variables reflecting an interaction of imports and particular structural aspects of the industry. Speculations about the future of competition in the United States are based on the regression equations explaining changes in concentration.I would like to thank John Caskey, Ellen Magenheim, Lee Perlman, Zora Pryor, F.

Measuring Market Power in the U.S. Aluminum Industry: A Residual Demand Approach

This paper applies a refined market power test to examine market power in the U.S. aluminum industry. The study conducts a two-step analysis in which the inverse residual demand facing the industry is first estimated to generate the associate elasticity to infer market power, and then the inverse partial residual demand facing the industry is estimated to produce the elasticity to measure the potential effect of inter-industry coordination. The results suggest that only the primary industry attains market power, and the market power can exert even without collusion between the primary and secondary industries.
