CONCEPTUAL ISSUES IN COST/BENEFIT ANALYSIS OF WELFARE-TO-WORK PROGRAMS

During the 1980s, a number of states operated welfare-to-work programs on a demonstration basis and subjected these demonstrations to formal cost/benefit evaluations. This paper examines the evaluators' methods and summarizes and interprets their findings. Cost/benefit analysis of welfare-to-work programs can provide a rough but useful assessment of a program's efficiency in reducing welfare caseloads. But the evaluation results are more difficult to interpret than they may appear to be. For example, the results typically imply that such programs produce small net gains to society when gains and losses are measured in terms of net income. However, a sensitivity analysis measuring net gains and losses to welfare recipients in terms of changes in net utility suggests that an important modification to the evaluators' methodology might well reverse this finding in many instances.

U.S. IMMIGRATION REFORM: POLICY ISSUES AND ECONOMIC ANALYSIS

In recent years, legal U. S. immigration has approached historically high levels, and illegal immigration has been thought to be high and perhaps rising. Consequently, the Select Commission on Immigration and Refugee Policy proposed sweeping changes in the nation's immigration laws. During 1984, both the Senate and House passed the Immigration Reform and Control Act (Simpson-Mazzoli Bill). This bill subsequently died in the conference committee that was established to reconcile differences between the bill's two versions. The proposed act has three major provisions: (1) control of illegal immigration, (2) legalization of alienstatus, and (3) reform of legal immigration. Both the House and Senate versions would maintain the present orientation of U.S. immigration policy toward family reunification, but the Senate proposed significant changes in legal immigration restrictions that would shift policy slightly more toward labor considerations. These proposed changes were eliminated in the compromise made in the conference committee. Employer sanctions and legalization of illegal aliens were left as the two most prominent alterations to existing policy. During 1985, the 99th Congress is likely to reconsider the Simpson-Mazzoli Bill, perhaps in a streamlined version which emphasizes employer sanctions, legalization, and a substantial increase in border enforcement.     

THE ISSUES RAISED BY THE EXPERIENCE OF UTILITY PRIVATIZATION IN THE UK

ABSTRACT^**: The UK utilities have all had a change of ownership over the last decade and a half. Does it really change things and, if so, in what ways? In fact, very little research has been carried out on this much copied experiment and evidence on efficiency gains is not that strong. But two main things have emerged. First, regulation and competition are the key drivers of change. It may well be that privatization was needed in the UK to allow these things to happen. It does not follow, however, that in other industries, or other countries, change is dependent on privatization. Second, different groups gain and lose (in absolute and relative terms) from privatization. In the UK, shareholders and large consumers have gained far more than small consumers, ex-employees and the tax payer. In particular, the fact that low-income consumers have done less well than the generality of consumers raises important issues for social cohesion and for policy.     

EFFECTS OF IMMIGRANTS ON THE 1980–1990 U.S. WAGE EXPERIENCE

This paper questions the claim that U.S. immigration should be reduced because the economy can no longer absorb immigrants as it has in the past. Analysis of male hourly wages shows that the effect of immigration on wages did not change between 1980 and 1990. Further, immigration had no negative effects on wages in 1980 or 1990. These results suggest that the capacity of the labor market to absorb immigrants has not been reduced. Additional analysis shows that, controlling for personal characteristics, the hourly wages of the average native and immigrant worker in areas of high and medium immigration relative to areas of low immigration increased between 1980 and 1990. However, Latino immigrants are affected negatively by immigration.     

HOUSEHOLD SAVING IN THE U.S.

In this paper the authors present evidence on household saving in the U.S. based on the panel data from the 1983 and 1986 waves of the Survey of Consumer Finances. Saving is measured in these surveys as the change in wealth over the three-year period. Using a variety of models, we are able to explain only about 7 percent of the variation in the level of saving. Demographic factors appear to be modestly useful in explaining saving. However, one fact is very clear from the patterns of correlation extracted so far: either the measurement error in the data is quite large, or idiosyncratic factors are very important in explaining saving behavior, or both.     

INCOME DISTRIBUTION IN THE U.S.S.R. IN THE 1980s

In 1989 Soviet authorities released unprecedented new data on the size distribution of income in the U.S.S.R. in the 1980s, including the distributions by republics. With the goal of providing a benchmark for evaluating the effect of current and future economic reforms on income distribution in the former Soviet Union, this paper estimates inequality measures for the new data. The estimation uses a simple nonparametric technique based on the Kolmogorov-Smirnov test to fit the Soviet data to a lognormal distribution. The results suggest that, for income from official sources, (1) inequality in the Soviet Union as a whole declined throughout the 1980s-both before and after Gorbachev's accession in 1985, and (2) income inequality was greater in the poorer, southern republics of the U.S.S.R. than in the north. While the inclusion of unofficial (unreported) private income would probably reinforce the second of these two trends, its effect on the first cannot be determined on the basis of available information.     

SCALE EFFECT VERSUS INDUCED POLICY RESPONSE IN THE ENVIRONMENTAL KUZNETS CURVE: THE CASE OF U.S. WATER POLLUTION

The environmental Kuznets curve (EKC) could arise from the scale effect in abatement technology as emphasized by Andreoni and Levinson (2001) or from the induced policy response as suggested by Grossman and Krueger (1995). This paper incorporates these two contrary views into a model and quantitatively evaluates their relative importance in shaping the EKC of U.S. water pollution. Our main findings include: (a) some scale effect in abatement technology must exist, otherwise the turning point of the EKC will be unreasonably high; (b) the scale effect alone is not sufficient to explain the practical occurrence of the turning point of the EKC; and (c) the scale effect features critically in the induced policy response as well.

FOREIGN MANPOWER IN THE U.S. SCIENCES

Because of the recent public concern over the brain drain, this study attempts to measure the U.S. gain of highly skilled manpower. The paper discusses the serious short-comings of the data on gross immigration of scientists and engineers provided by the U.S. immigration authorities as a measure of true U.S. gains. In a case study of Swedish scientists and engineers it was found, for example, that whereas the U.S. data showed a gain of 106 Swedish scientists and engineers over a number of years, the net figure was only 26 after adjustment for remigration and the application of the proper OECD education criteria. The paper then reports the findings of a statistical study which uses the stock data on U.S. scientists in the National Register of Scientific and Technical Personnel to estimate the number of foreign born in this stock and analyse their characteristics with respect to age, educational attainment, and employment preferences. It was found that nearly 7 percent of all U.S. scientists are of foreign origin (foreign born and foreign secondary education), whereas 11.5 percent of all scientists with a Ph.D. are of foreign origin. The percentage among Ph.D. holders is highest in meteorology (22.3), followed by linguistics (18.7), physics (17.1) and statistics (14.6). The greatest percentage of scientists comes from Canada (10.4 per thousand), followed by Germany (8.3 per thousand) and the United Kingdom (6.7 per thousand). However, after adjustment of these data for the different sizes of the total foreign born population from each country in the U.S., it turns out that by this measure the greatest shares of scientists are supplied by the Japanese, followed by the Austrian-Swiss, Benelux and Canadians. The analysis of the age composition of all foreign born reveals that in the age groups that were 20–29, 45–54, and 65 and over in 1964 foreigners represent a smaller than average share, probably reflecting war casualties and education completed at a later age. Germans and Austrians are heavily concentrated in the group 55–64 years old in 1964, suggesting that a great share of scientists from these countries may have been victims of a brain push.

美元本位制、美元霸权与美国金融危机

美元本位制下,美元霸权表现为中心一外围框架体系.在该体系下,中心国美国与外围国家的权益和义务不对称,地位不对等,而且框架体系本身具有内在的不相容性,这些特征决定了美元本位制的内在脆弱性,由此也使美国落入美元本位制的陷阱,造成美国国内利率下降、消费信用过度扩张、制造业陷入衰退等经济失衡,最后当信用泡沫破灭时,金融危机爆发.     

NON-CORPORATE SECTOR FINANCE AND FINANCING OF SMALL INDUSTRIES IN DEVELOPING COUNTRIES: THE NIGERIAN EXPERIENCE

This paper attempts to report the author's findings regarding the role of the non-corporate sector in providing investment finance for small-scale industries in Nigeria, through co-operative efforts. It specially underlines the role of indigenous social organizations and group relations in solving the economic problems of a developing economy which places emphasis on industrial development. Though these sources provide short-term consumption finance, they certainly constitute an inadequate source of long-term finance for industry in a situation where the importance of small-scale industry development is officially greatly emphasized, and existing financial institutions are designed to serve only the financial needs of large industrial enterprises. The role of government in the context of the dilemma of the small-scale entrepreneur is examined and suggestions made for improvements. The paper reflects what is probably the experience of many developing countries trying to industrialize.     

WAGES AND EMPLOYMENT IN THE U.S. APPAREL INDUSTRY

This article uses individual-level data from the U.S. Census, Public Use Microdata Sample (PUMS), to examine wages and employment in the U.S. apparel industry. Total employment in this sector has been falling since 1970, and its overall average wage is the lowest of 25 industry aggregates. But disaggregation by gender, education, and nativity reveals that groups of highly educated male native workers earn higher average wages in apparel than in other industries. Moreover, after adjusting for observed individual differences in human capital (in addition to the three characteristics used to form worker subsets), highly educated male natives earn positive wage premiums in this sector. In contrast, most categories of immigrants and female natives earn relatively low average wages and experience negative wage premiums in apparel. This variation in the adjusted industry wage premiums across worker groups may be related to apparel's relative exposure to imports and immigrant workers.     

WEALTH HOLDINGS AND POVERTY STATUS IN THE U.S.

Families below the poverty line are better off in terms of wealth than income. In 1962, the ratio of mean income between families below and above the poverty line is 0.19 and the ratio of mean wealth is 0.29. The corresponding ratios for 1983 are 0.16 and 0.19. On average, the elderly poor are better off in terms of wealth than the younger poor, particularly relative to their own income. However, the poor have become worse off in terms of wealth between 1962 and 1983, when their real income grew by 6 percent and their real wealth declined by 11 percent. The inclusion of pension and social security wealth in the household portfolio narrows the wealth gap between the poor and non-poor, particularly for families under 65 years of age. Alternative poverty rates are also calculated based on the inclusion of annuity flows from wealth in household income. The reduction in the poverty rate between 1962 and 1983, from 21 to 15 percent on the basis of the official rate, is considerably lower with these alternative definitions.     

PRIMARY VERSUS SECONDARY PRODUCTION TECHNIQUES IN U.S. MANUFACTURING

In this paper we analyze the determinants of material inputs into individual production activities as a function of their outputs. We use observations on a large cross-section of U.S. manufacturing plants from the Census of Manufactures, including those that make goods primary to other industries, to study differences in production techniques. We find that in most cases material requirements do not depend on whether goods are made as primary products or as secondary products. We thus elucidate support for the commodity technology model as a useful working hypothesis.     

U.S. INCOME MOBILITY IN THE SEVENTIES AND EIGHTIES

This paper focuses on three questions: (1) Was mobility within the income distribution in the 1980s different from the 1970s? (2) Is there as much mobility when some measure of permanent income is used? and (3) Does movement within the income distribution imply real income changes'? Income mobility between 1969 and 1976, and between 1979 and 1986 is examined using real family income from the Panel Study of Income Dynamics. The results show that there is considerable movement within the income distribution when both annual and permanent income is used. This movement, however is generally not very great in either direction.     

THE EFFECTS OF U.S.-CHINA TRADE ON EMPLOYMENT AND WAGES IN THE U.S.-MEXICO BORDER REGION

This article investigates the impact of foreign competition from China on employment and wages in four U.S.-Mexico Border counties: Santa Cruz, Arizona; San Diego, California; El Paso, Texas; and Webb, Texas. Using disaggregated industry-level data between 1992 and 2006, we find that increased trade with China is associated with significantly lower county-industry employment and wages. In contrast, and as expected, increased imports from Mexico are positively related to increased employment and wages in U.S.-Mexico border counties. The results indicate that the U.S.-Mexico supply-chain relationship related to the maquiladora industry is significantly affected by Chinese competition. Implications for policy include an increased focus on federal programs that are intended to diversify the border economy . ( JEL F13, F43, F23)
