We use a demand/supply framework to analyze 1) the decline in union membership since 1977 in the United States and 2) the difference in unionization rates between the United States and Canada. We extend earlier work on these problems by analyzing new data for 1991 from the General Social Survey and for 1992 from our own household survey on worker preferences for union representation. When combined with earlier data for 1977 from the Quality of Employment Survey and for 1984 from a survey conducted for the AFL-CIO, we are able to decompose changes in unionization into changes in demand and changes in supply. We also analyze data for 1990 from a survey conducted for the Canadian Federation of Labor on the preferences of Canadian workers for union representation. We find that virtually all of the decline in union membership in the United States between 1977 and 1991 is due to a decline in worker demand for union representation. There was almost no change over this period in the relative supply of union jobs. Additionally, very little of the decline in unionization in the U.S. can be accounted for by structural shifts in the composition of the labor force. Next, we find that all of the higher unionization rate in the U.S. public sector in 1984 can be accounted for by higher demand for unionization and that there is actually more frustrated demand for union representation in the public sector. Finally. we tentatively conclude that the difference in unionization rates between the U.S. and Canada is accounted for roughly in equal measure by differences in demand and in supply.

Some workers bargain with prospective employers before accepting a job. Others could bargain, but find it undesirable, because their right to bargain has induced a sufficiently favorable offer, which they accept. Yet others perceive that they cannot bargain over pay; they regard the posted wage as a take-it-or-leave-it opportunity. Theories of wage formation point to substantial differences in labor-market equilibrium between bargained and posted wages. The fraction of workers hired away from existing jobs is another key determinant of equilibrium, because a worker with an existing job has a better outside option in bargaining than does an unemployed worker. Our survey measures the incidences of wage posting, bargaining, and on-the-job search. We find that about a third of workers had precise information about pay when they first met with their employers, a sign of wage posting. We find that another third bargained over pay before accepting their current jobs. And about 40 percent of workers could have remained on their earlier jobs at the time they accepted their current jobs.

About 3% of GNP is spent on government labor market programs in Sweden, compared to 2 % in Germany and less than 0.5% in the U.S. In Sweden these programs include extensive job training, mobility bonuses and unemployment benefits. Reviews of previous literature suggest that job training programs have small effects on wages and re-employment in Sweden, but precise inferences are difficult because of small sample sizes. The authors also investigate alternative reasons for the stability of the Beveridge Curve in Sweden, and compare regional evolutions of employment and unemployment in Sweden and the U.S. Lastly a cross-country analysis is presented showing that the extent of a country''s active labor market program is positively associated with the national unemployment rate.

This paper reports the results of surveys of specialists in labor economics and public economics at 40 leading research universities in the United States. Respondents provided opinions of policy proposals; quantitative best estimates and 95% confidence intervals for economic parameters; answers to values questions regarding income redistribution, efficiency versus equity, and individual versus social responsibility; and their political party identification. We find considerable disagreement among economists about policy proposals. Their positions on policy are more closely related to their values than to their estimates of relevant economic parameters or to their political party identification. Average best estimates of the economic parameters agree well with the ranges summarized in surveys of relevant literature, but the individual best estimates are usually widely dispersed. Moreover, economists, like experts in many fields, appear more confident of their estimates than the substantial cross-respondent variation in estimates would warrant. Finally although the confidence intervals in general appear to be too narrow, respondents whose best estimates are farther from the median tend to give wider confidence intervals for those estimates.

This paper reinvestigates the evidence on the impact of the minimum wage on employment in Puerto Rico. The strongest evidence that the minimum wage had a negative effect on employment comes from an aggregate time series analysis. The weakest evidence comes from cross-industry analyses. The main finding of the paper, however, is that the statistical evidence of a negative employment effect of the minimum wage in Puerto Rico is surprisingly fragile.

In 1988, the wage distribution in East Germany was much more compressed than in West Germany or the U.S. Since the collapse of Communism and unification with West Germany, however, the wage structure in eastern Germany has changed considerably. In particular, wage variation has increased, the payoff to education has decreased somewhat, industry differentials have expanded, and the white collar premium has increased. Although average wage growth has been remarkably high in eastern Germany, individual variation in wage growth is similar to typical western levels. The wage structure of former East Germans who work in western Germany resembles the wage structure of native West Germans in some respects, but their experience-earnings profile is flat.

Two-stage-least-squares (2SLS) estimates are biased towards OLS estimates. This bias grows with the degree of over-identification and can generate highly misleading results. In this paper we propose two simple alternatives to 2SLS and limited-information-maximum-likelihood (LIML) estimators for models with more instruments than endogenous regressors. These estimators can be interpreted as instrumental variables procedures using an instrument that is independent of disturbances even in finite samples. Independence is achieved by using a `leave-one-out'' jackknife-type fitted value in place of the usual first-stage equation. The new estimators are first-order equivalent to 2SLS but with finite-sample properties superior to those of 2SLS and similar to LIML when there are many instruments. Moreover, the jackknife estimators appear to be less sensitive than LIML to deviations from the linear reduced form used in classical simultaneous equations models.

A reduction in trade barriers generally will affect the environment by expanding the scale of economic activity, by altering the composition of economic activity, and by bringing about a change in the techniques of production. We present empirical evidence to assess the relative magnitudes of these three effects as they apply to further trade liberalization in Mexico. In Section 1. we use comparable measures of three air pollutants in a cross-section of urban areas located in 42 countries to study the relationship between air quality and economic growth. We find for two pollutants (sulfur dioxide and "smoke") that concentrations increase with per capita GDP at low levels of national income, but decrease with GD? growth at higher levels of income. Section 2 studies the determinants of the industry pattern of U.S. imports from Mexico and of value added by Mexico''s maquiladora sector. We investigate whether the size of pollution abatement costs in the U.S. industry influences the pattern of international trade and investment. Finally, in Section 3, we use the results from a computable general equilibrium model to study the likely compositional effect of a NAFTA on pollution in Mexico

Germany has experienced a high and rising rate of anti-foreigner violence during the early 1990s. To analyze the determinants of crime against foreigners we assembled a new data set on the number and nature of such crimes at the county level based on newspaper reports. We find significant differences in the patterns of violence in the eastern and western parts of the country. The incidence of anti- foreigner crime is higher in the east and rises with distance from the former west German border. Economic variables like unemployment and wages matter little for the level of crime once location in the east is taken into account. The relative number of foreigners in a country has no relationship with the incidence of ethnic crimes in the west, whereas in the east it has a positive association with the number of crimes per resident and a negative association with the number of crimes per foreign resident.

The positive social benefits of low unemployment are many—it helps to reduce poverty and crime and fosters more stable families and communities. Yet conventional wisdom—born of the stagflation of the 1970s—holds that sustained low unemployment rates run the risk of triggering inflation. The last five years of the 1990s—in which unemployment plummeted and inflation remained low—called this conventional wisdom into question. The Roaring Nineties provides a thorough review of the exceptional economic performance of the late 1990s and asks whether it was due to a lucky combination of economic circumstances or whether the new economy has somehow wrought a lasting change in the inflation-safe rate of unemployment. Led by distinguished economists Alan Krueger and Robert Solow, a roster of twenty-six respected economic experts analyzes the micro- and macroeconomic factors that led to the unexpected coupling of low unemployment and low inflation. The more macroeconomically oriented chapters clearly point to a reduction in the inflation-safe rate of unemployment. Laurence Ball and Robert Moffitt see the slow adjustment of workers'' wage aspirations in the wake of rising productivity as a key factor in keeping inflation at bay. And Alan Blinder and Janet Yellen credit sound monetary policy by the Federal Reserve Board with making the best of fortunate circumstances, such as lower energy costs, a strong dollar, and a booming stock market. Other chapters in The Roaring Nineties examine how the interaction between macroeconomic and labor market conditions helped sustain high employment growth and low inflation. Giuseppe Bertola, Francine Blau, and Lawrence M. Kahn demonstrate how greater flexibility in the U.S. labor market generated more jobs in this country than in Europe, but at the expense of greater earnings inequality. David Ellwood examines the burgeoning shortage of skilled workers, and suggests policies—such as tax credits for businesses that provide on-the-job-training—to address the problem. And James Hines, Hilary Hoynes, and Alan Krueger elaborate the benefits of sustained low unemployment, including budget surpluses that can finance public infrastructure and social welfare benefits—a perspective often lost in the concern over higher inflation rates. While none of these analyses promise that the good times of the 1990s will last forever, The Roaring Nineties provides a unique analysis of recent economic history, demonstrating how the nation capitalized on a lucky confluence of economic factors, helping to create the longest peacetime boom in American history.
