Testing for a Structural Change in U.S. Wage Determination

Previous tests for structural changes (slope changes) and shifts (intercept changes) in the Phillips curve and union wage determination specify the date of structural change a priori. This article tests for structural changes and shifts without specifying the change point ex ante . The results support the belief that structural changes occurred in the early 1980s. Contrary to some previous research, however, the results do not support a structural shift in the Phillips curve.     

New Trends in U.S. Industrial Concentration

Using weighted concentration ratios for the entire economy, I argue that industrial concentration decreased in the U.S. from 1960 to the early1980s and then began to increase. This rise in the last two decades of the 20th century offsets any counteracting affectsstemming from the growth of use of information technology in production or from imports and appears due primarily to the impact of the merger wave starting in the mid 1980s. I also considerbriefly the relationship between increasing market concentrationand a change in market competition,taking into account the expansion of e-commerce.     

Union Wage Gap in the U.S. Construction Sector: 1983–2007

Wage gap decomposition shows that declining union power was the principal force behind the shrinking union wage premium in the U.S. construction industry between the 1980s and the 2000s. This decline was largely offset by changes in returns to workforce attributes and workforce compositions. Without these moderating effects, the decline in the wage gap would have been twice as large (in log points). The patterns were similar in the basic and mechanical trades, but magnitudes of change were larger in the latter.     

On the Absence of Directional Price Discrimination in the U.S. Airline Industry*

Certain forms of price discrimination in oligopoly markets can lead to more aggressive competition and lower profits, yet few empirical studies examine how extensively such strategies are used. I consider one such strategy, testing whether airlines charge different prices on the same flights to passengers that originate from different endpoints. Using fare quote data I formulate a new approach to measure discrimination while controlling for cost heterogeneity and find that carriers within the U.S. domestic market do not engage in directional price discrimination despite frequently using other similar pricing strategies that are unlikely to enhance competition.     

Wage Discrimination Against Workers with Sensory Disabilities

We link information on occupation‐specific job demands to data from the Survey of Income and Program Participation to provide first‐ever estimates of wage discrimination against workers with sensory disabilities. Estimates are derived from wage models that control for job demands related to sensory abilities, and interactions between job demands and workers' sensory limitations. Results indicate approximately one third (one tenth) of the male (female) disability‐related wage differential is potentially attributed to discrimination. The results differ from estimates of discrimination against workers with physical disabilities obtained with similar methods, underscoring the importance of accounting for heterogeneity of the disabled population in discrimination studies.     

The Sexual Orientation Wage Gap for Racial Minorities

We explore the sexual orientation wage gap across four race and ethnic groups in the 2000 U.S. Census: Asian, black, Hispanic, and white. Using decomposition analysis, we explore if racial minority groups experience the same pattern of sexual orientation wage differences as their white counterparts, and how racial and sexual orientation wage differences interact over the distribution of wages. For men, we show a combined unexplained penalty greater than the sum of their individual unexplained race and sexual‐orientation differentials. Racial minority lesbians, however, earn higher wages than what the sum of their racial and sexual‐orientation analyses would suggest.     

FHA, Racial Discrimination and Urban Mortgages

The empirical validity of two propositions regarding FHA unsubsidized single-family activity are explored at the neighborhood level in this paper. The propositions are first that FHA serves moderate-to-middle-income families, not low-income families who live in the inner city nor high-income families who live in the outer suburbs; and second that all other things being equal, black owner-occupants are more likely to have an FHA-insured mortgage than are whites
Two methods of analysis are performed: mapping and regression. First, 1974 FHA activity in the Philadelphia metropolitan area is mapped by race—black and white—and program—203(b), 221(d)(2), and 223(e)—at the census tract level. Then, the FHA activity by race and by program is regressed on 1970 neighborhood housing and population characteristics, again, using the census tract as the unit of observation. The results of the analysis provide support for both propositions. In Philadelphia in 1974, FHA is to a degree a border program differentially serving blacks.     

Comparing technology education in the U.S. and U.K.

British and American discourses and experiences with respect to technology education are compared. Out of this comparison important issues are identified that have implications for the larger ongoing conversation on technology beyond these countries. They include the role of the state in establishing and validating the subject, the dual claims of technology literacy and technological capability, and dual curricular approaches — content and process.     

Winning in the U.S.Activewear Market

A revolution in the U.S. activewear marker is being driven by the convergence of several consumer and retail trends.According to Cotton ncorporated＇s 2014 Sports Apparel Survey,more than nine in ten consumers say they wear athletic wear for activities other than exercise.ncreased consumer demand has prompted U.S athletic apparel sales o grow at double the rate of non-active apparel sales for several years.Strong sales growth has convinced mass merchants,fast-fashion etailers,and luxury brands to enter or increase offerings in this S33billion dollar morket previously dominated by o smaller cadre ofoutdoor and sports apparel retailers and brands     

Capital Investment and Amortization Policies in the U.S.S.R.

This article deals with the two major problems in depreciation: how to determine actual wear and tear and, thus, life of equipment; and how to treat depreciation and its associated expenses in the accounting records. With regard to the first, the author recognizes that a certain amount of arbitrary action is probably inevitable. Industry in the USSR is evidently bound by its own equivalent of “Bulletin F”, which sets “amortization norms” or depreciation allowances for each class of machinery; and it is found that these often do not correspond to actual operating experience. The machine may be scrapped either before its allocated life span, or survive fully depreciated. This fact is, of course, quite familiar, and the author has no suggestions to offer beyond pointing out the problem. He also questions, for technical reasons, the straight line method which is now generally used. Yet it is almost impossible to justify, on functional grounds, any regulated alternative method, such as declining balance or sum-of-the-years-digits.     

Europe's lessons for the U.S

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

美国纸箱业实施"精益生产"

美国纸箱业认为“精益生产”能实现真正的零库存和快速的市场反应机制.“我不会购买,除非所有的经理主管人员都认为成本在持续上涨,他们不会为新科技而支付钞票,除非该技术能够在增加产量的同时把支出分流出他们的系统.”美国包装公司（PCA）的Martin认为,自从上世纪70年代瓦楞纸板制造机的持续研发以来,机械已经有了很大突破.
