A STATISTICAL ANALYSIS OF PRODUCTIVITY IN SELECTED SERVICE INDUSTRIES IN THE UNITED STATES, 1939–1963

This paper examines differentials in output, employment and productivity across seventeen service industries in the United States from 1939 to 1963. Included are 9 retail trades and 8 services mostly from the personal service group. The industries chosen were those for which it was possible to obtain from available data reasonably comparable measures of output and input for selected years since 1939. Also, they are industries for which it is possible to calculate a measure of real output that is not based on labor input.
Sixteen of the industries show positive rates of change of real output per man. Thus there appears to be no basis for assuming that productivity cannot or does not increase in industries providing services. However, the rate of increase for the group as a whole was not as rapid as in manufacturing or in goods production as a whole.
The data for the seventeen industries give strong support to the hypothesis of a positive correlation between industry rates of growth and rates of change of productivity. The correlations are of the same order of magnitude as those found by other investigators in studies of manufacturing industries.
The coefficient of correlation between growth of output per man and growth of output is .93; between growth of output per man and growth of employment it is .54 for 1939–1963. The comparable coefficients for the 1948–1963 period are .70 and .13.
The results also parallel those reported for manufacturing in one other respect, namely, the absence of any correlation between changes in output per man and changes in compensation per man.
The paper concludes with a discussion of the problems encountered in measuring changes in real output in these industries and presents some alternative estimates based on different concepts and different sources.     

David Dubinsky,the International Ladies’ Garment Workers’ Union and the Limits of Social Democratic Trade Unionism

Unlike Parmet’s (2005) well-written and thoroughly researched biography and many other generally admiring books and articles on David Dubinsky, the former International Ladies’ Garment Workers’ Union (ILGWU) president from 1932 to 1966, this essay contends that even though Dubinsky initiated important developments within the ILGWU and fought heroically against Nazism and Fascism, his right-wing social democratic worldview was ultimately divisive to the achievement of national and international working class unity. Dubinsky’s political positions become evident through his vigorous anti-Communism which he engaged in with regards to his dealings with Communists in the ILGWU, the Congress of Industrial Organizations, and the American Labor Party. Moreover, the exporting of his anti-Communism abroad via the American Federation of Labor’s Free Trade Union Committee and the International Confederation of Free Trade Unions damaged international working class unity through the sabotaging of radical trade unionism not only in Western Europe but in nations around the globe. Understanding Dubinsky’s anti-Communism is the key for ultimately comprehending the garment union leader’s politics.     

Efficiency and Technological Change in the U.S. Brewing Industry

This study demonstrates that the measurement of technological change and economic efficiency are tightly linked. Efficiency measures may depend on carefully controlling for technological change, while tests of technological change may be sensitive to empirical model specifications. Moreover, the study underlines Solow's (1994) and Romer's (1994) admonition that econometricians should pay attention to industry and institutional evidence in building models of technological change. The empirical results presented here suggest that there has been substantial technological change in the U.S. brewing industry from 1950 to 1992. This occurred in the form of a dramatic shift in technology beginning with the introduction of super breweries in about 1972. There has also been a substantial increase in scale economies, which undoubtedly caused many inefficiently small firms to exit the industry during the 1960s and 1970s. Further results suggest that a more complete specification of technological change and the stochastic nature of the frontier production function leads to higher and more tenable estimates of efficiency.     

Field publishing performance of U.S. economics departments

Conclusion The purpose of this study is to reduce information costs in the market for graduate education in economics and the market for Ph.D. economists by providing information on research concentration in each of 19 fields for 1980–1986. Some variation in publishing performance across fields is found in highly regarded universities. Unexpected faculty strength is discovered in some middle level departments for particular fields. Among middle- and lower-ranked departments, substantial publishing diversity across fields is evident.     

Innocents Abroad: Attitude Change toward Hosts

The purpose of this study was to examine the role of social distance, prior expectations, and trip experience on post-trip attitudes in multiple destinations. This study is based on surveys conducted with two groups of students: 1) a group participating in a summer study abroad program to the South Pacific or to Europe, and 2) a control group. The results show that attitude changes were positive towards Europeans, negative towards Australians, and mixed towards Fijians. This study supports the expectation value theory, but contradicts the cultural distance theory of attitude change. Further, the results show that experience with non-tourism related services played an important role toward attitude change.     

Informational Contagion of Sudden Stops in a Global Games Framework

This paper highlights the cross-country spread of self-fulfilling financial crises through an informational channel. It sets up a two-country framework of investment with strategic complementarities and incomplete information about economic fundamentals. Each market may be subject to sudden stops, triggered by agents preemptively withdrawing their investments for fear others do so. After observing a massive capital outflow from one country, agents downgrade common fundamentals, and therefore have higher requirements regarding factors specific to the other country. This in turn may induce a crisis in the latter, which is not justified by idiosyncratic events or economic interdependence.     

Disease management programs: program intervention, behavior modification, and dosage effect

Disease management programs provide highly personalized self- management support to consumers afflicted with chronic illnesses. Program interventions include the provision of health information, ongoing motivation, and support for behavior change, adherence to pharmacotherapy, development of self-efficacy, and the distribution of self-care tools. Interactions between program and patients are structured and repetitive over time. Consumer behavior change can result in measurable improvements in quality and medical cost savings from postponement or avoidance of preventable complications. We evaluated the impact on cost and quality of a comprehensive Diabetes Disease Management Program (DDMP) across ten US urban markets. A staggered implementation allowed for ten pre–post and five pair-wise comparisons. The DDMP demonstrated significant improvements in six diabetes-related quality indicators, lower cost, and a dose-response with greater than 6 months participation. We conclude that a DDMP improves quality of care and reduce overall medical costs.
