EFFICIENCY AND LABOR MARKET DYNAMICS IN A MODEL OF LABOR SELECTION

This article characterizes efficient labor market allocations in a labor selection model. The model's crucial aspect is cross‐sectional heterogeneity for new job contacts, which leads to an endogenous selection threshold for new hires. With cross‐sectional dispersion calibrated to microeconomic data, 40% of empirically relevant fluctuations in the job‐finding rate arise, which contrasts with results in an efficient search and matching economy. The efficient selection model's results hold in partial and general equilibrium, as well as with sequential search.     

FOREIGN OWNERSHIP, WAGES, AND WAGE CHANGES IN U.S. INDUSTRIES, 1987–92

The authors construct a data set by industry by state by ownership for establishments in the United States using 1987 and 1992 U.S. Census and Bureau of Economic Analysis matched data to investigate the relationship between foreign ownership and wages. They find evidence that foreign-owned establishments pay higher wages in manufacturing, retail trade, and other relatively low-skill industries, but not in other higher-skill industries. A growth in the fraction of employment in foreign establishments was not significantly associated with an increase in overall wages. There is no evidence of a wage spillover to domestic establishments. (JEL J3 , F2 )     

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.     

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)     

SKILL BIAS AND EMPLOYMENT FRICTIONS IN THE U.S. LABOR MARKET 1970–1990*

This article studies simultaneous changes in four labor market variables: the unemployment rates for college and high‐school graduates, the education wage premium, and the level of college participation. It develops an equilibrium search and matching model of the labor market where education is endogenously determined. Then the model is used to investigate quantitatively whether the change in the above labor market variables from 1970 to 1990 in the United States can be traced to changes in the environment. A skill‐biased change in technology together with an increase in employment frictions can explain much of the observed variation in these variables.     

REGULATION,IMPERFECT COMPETITION,AND THE U.S. ABORTION MARKET

The U.S. abortion market has grown increasingly concentrated recently, while many states tightened abortion laws. Using data on abortion providers, I estimate an equilibrium model of demand, price competition, entry and exit, to capture the effect of regulation on industry dynamics. Estimates show regulations played an important role in determining the abortion market structure and evolution. Counterfactual simulations reveal increases in demand‐aimed regulation were the most important observed factor in explaining recent abortion declines. Simulating Utah's regulatory regime nationally shows tightening abortion restrictions can increase abortions in equilibrium, mainly through tilting the competitive landscape toward low‐price providers.     

WAGE DIFFERENTIALS, DISCRIMINATION AND INEQUALITY: A CAUTIONARY NOTE ON THE JUHN, MURPHY AND PIERCE DECOMPOSITION METHOD

This paper shows how difficult it is to study the roles of discrimination and unobserved skills when studying changes in racial and gender wage gaps over time by examining merits and shortcomings of a popular decomposition method by Juhn, Murphy and Pierce (JMP). The JMP method shows that wage dispersion can offer a compelling explanation of the wage gap. However, JMP have to rely on a few strong assumptions in order to derive their decomposition equation, which introduces wage inequality as the price of unobserved skills (the standard deviation of the residuals) into their decomposition equation.     

双重垄断下中国垄断行业改革:逻辑次序与路径选择

我国的垄断现状是由传统的计划经济体制衍生而来的,其本质特征是寄附于自然垄断之上的过度行政性垄断。垄断行业改革涉及竞争、产权、规制与治理等多个层面,它们之间的不同组合及其协同互动关系共同决定了特定行业的产业绩效水平。中国的垄断行业改革,必须遵循优先重构规制体系、分类渐次破除行政性垄断的总思路,从产权、竞争、规制与治理等各个层面作出相应的制度安排。     

A DYNAMIC DECISION MODEL OF MARRIAGE,CHILDBEARING, AND LABOUR FORCE PARTICIPATION OF WOMEN IN JAPAN*

This paper empirically examines marriage, child bearing and labour force participation behaviour of fertile‐aged women in Japan, applying an estimable dynamic model of dis‐crete choice. Using microdata from the 1994–1999 Japanese Panel Survey of Consumers, the structural estimation result suggests that, overall, women are worse off with marriage and part‐time work without financial benefits. Women are better off having two or more children, but considerably worse off because of the burden of raising infants. In addition, probabilities of finding full‐time work after career interruption are estimated at about 18% for university educated women and 12–13% for less educated women.     

INFLUENCE, ELECTIONS, AND THE VALUE OF A VOTE IN THE U.S. HOUSE OF REPRESENTATIVES

This paper investigates the extent to which interest groups use their campaign contributions to affect election outcomes as opposed to influencing candidate policy choices directly. It also reveals how much value interest groups place on gaining one more favorable vote in the House of Representatives. The empirical estimates suggest that gaining influence dominates helping favored candidates win the election as a means to affect defense spending policies. Political action committees differ in interesting ways, however, with the more ideological peace groups placing greater emphasis on changing electoral outcomes than do investor lobbies representing the defense industry.     

国际贸易的麦敕勒悖论及其验证:来自美国及OECD成员国的经验证据

本研究采用大数据样本(样本容量为173430)研究了外商直接投资(国外直接投资和港澳台直接投资)外溢效应在空间上的分布规律以及对我国企业生产率的影响,实证结果发现无论港澳台直接投资还是国外直接投资对内资企业均存在外溢的比邻效应;考虑地区进入因素后,外商直接投资对制造业的整体效应估计值降低了;外商直接投资的进入拉大了我国不同区域企业生产率之间的差距。此外,研究结论支持了Arrow(1971)与Findlay(1978)的理论推断。     

VEHICLE CHOICE BEHAVIOR AND THE DECLINING MARKET SHARE OF U.S. AUTOMAKERS*

We develop a consumer‐level model of vehicle choice to shed light on the erosion of the U.S. automobile manufacturers' market share during the past decade. We examine the influence of vehicle attributes, brand loyalty, product line characteristics, and dealerships. We find that nearly all of the loss in market share for U.S. manufacturers can be explained by changes in basic vehicle attributes, namely: price, size, power, operating cost, transmission type, reliability, and body type. U.S. manufacturers have improved their vehicles' attributes but not as much as Japanese and European manufacturers have improved the attributes of their vehicles.     

MAINTAINING MARKET POSITION: TEAM PERFORMANCE,REVENUE AND WAGE EXPENDITURE IN THE ENGLISH PREMIER LEAGUE

This paper investigates the relationship between playing success and commercial success in team sports. Utilizing a data set relating to the English Premier League that combines both financial measures and indicators of playing skills and performances, our empirical analysis is based on three behavioural equations. Our analysis indicates that on‐field success can be directly related to players’ skills and abilities and that revenue is positively related to on‐field success. Wage expenditure is also shown to systematically reflect player skills and performances. One interpretation of this evidence is that investment in players’ skills and ability buys on‐field success, with richer teams becoming ever richer and able to maintain or even build upon success by spending more on players than less successful clubs. To the extent that richer clubs are successful in their objective there is a causal link between revenue earned and competitive imbalance via investments in players. The implications of this tendency within a league are discussed in our conclusion, which also considers the potentially wider implications of our study as they relate to the evolution of firm size and issues of market share.     

ACTIVE LABOR MARKET PROGRAMS AND REGIONAL MOBILITY OF LABOR: EVIDENCE FROM THE SWEDISH RECESSION, 1994–1995

This paper addresses the impact of active labor market programs on interregional migration in Sweden. The purpose of the study is to determine the extent to which the programs, which provide training and labor market assistance to jobless individuals, induce participants to migrate. Analysis is based on data registers compiled in 1994 and 1995 by Statistics Sweden and the Labor Market Board of Sweden. The paper specifies and estimates a two‐equation model of participation and subsequent migration. The model, which is estimated by the method of maximum simulated likelihood, accounts for the role of program participation as an endogenous choice variable in the decision to migrate. In an attempt to capture the effect of migrant self‐selection, the estimation approach also controls for unobserved heterogeneity in the participation and migration equations. Results of the study indicate a significant positive impact of participation on subsequent mobility for males. This result is robust with respect to alternative specifications of the migration equation and alternative formulations of the model for program participation. For females, the evidence of program impacts is mixed and it appears to be sensitive to the statistical formulation of the model. (JEL J38, J61)     

PORTFOLIO SELECTION BETWEEN A MATURE MARKET AND SELECTED EMERGING MARKETS INDICES IN THE PRESENCE OF STRUCTURAL BREAKS

The paper examines the influence of the structural breaks on the optimal weights, hedge ratios and hedge effectiveness index (HEI) of risk‐minimizing portfolios composed of S&P500 and selected emerging markets’ indices from East Europe, Asia and South America. We employ a bivariate DCC‐EGARCH models without and with structural breaks and we find better estimation features when structural breaks are included in the model. However, we do not find evidence that insertion of structural breaks increases portfolio hedging performances. The differences that exist between optimal weights, hedge ratios and HEI values are so small that tangible economic benefit for international investors do not exist.     

ECONOMIC FREEDOM AND GROWTH IN U.S. STATE‐LEVEL MARKET INCOMES AT THE TOP AND BOTTOM

This paper investigates the relationship between economic freedom and income growth and inequality across U.S. states over the period 1979–2011. The focus is on market income at the top and bottom of the income distribution. Results show that increases in overall freedom are associated with average income growth. When viewed separately, an increase in overall freedom is associated with larger income growth rates for income earners in the bottom 90% relative to the top 10%. Interestingly, results show that increases in overall economic freedom are related to larger relative growth rates for the top 10% incomes within high‐income states and larger relative growth rates for the bottom 90% incomes within low‐income states. Top‐to‐bottom income ratio regressions suggest a negative and statistically significant relationship between economic freedom and income inequality. (JEL D63, P16, R11)     

AGRICULTURAL CO-OPERATION IN THE EASTERN STATES OF THE U.S.A

The Year-Book of Agricultural Cooperation, 1940, which has just been published by the Horace Plunkett Foundation (1) contains a detailed and extremely competent study on agricultural cooperation in the eastern part of the United States by Miss Margaret Digby, Secretary of the Foundation. The study is based on personal experience collected by the author during a tour in the spring of 1939.
We reproduce below the last chapter of this study in which Miss Digby summarises some of her observations.
