Additively Decomposable Segregation Indexes. The Case of Gender Segregation by Occupations and Human Capital Levels in Spain

Building upon the ideas first exposed by Theil and Finizza (1971) and Fuchs (1975), this paper presents an additively decomposable segregation index based on the entropy concept used in information theory. For any pair of classification variables in a given year, the index is decomposed into a between-group and a within-group term. To analyze intertemporal changes in gender segregation for a given partition, the index is decomposed into two terms that capture, respectively, gender composition effects, and changes in the groups' demographic importance. These decompositions are illustrated with Spanish data on occupations and human capital levels for 1977 and 1992. It is found that, in both years, the higher the educational level, the smaller is gender segregation for most age groups. Moreover, gender segregation decreases with age in all educational categories. However, most gender segregation takes place within, rather than between, age/education categories. Lastly, changes in gender composition across occupations, nearly offset by occupational mix changes, account for a decline of 2% in total gender segregation over this period.     

CAN WE INFER HOSPITAL QUALITY FROM MEDICAL GRADUATES’ RESIDENCY CHOICES?

This paper uses a novel approach to infer hospital technical quality from revealed preferences over residency programs. Specifically, we use Spanish medical graduates’ residency choices made from 1995 to 2000. We start by estimating a model of medical graduates preferences that controls for hospital, proximity, specialty, and gender effects. We interpret the coefficients on the hospital dummy variables as measures of medical graduates’ preferences over hospitals. Our results show that graduates do indeed discriminate between hospitals and that their preferences correlate with hospital‐specific covariates arguably related to hospital training quality. We then show that preferences from medical graduates are positively and statistically significantly correlated with risk‐adjusted hospital rankings based on five alternative outcome measures. Finally, we construct reputation scores for each hospital using news story counts in three media outlets and find that medical graduates’ preferences are especially valuable for inference of hospital technical quality of care as they do not simply reflect well known reputation.     

Cross‐Border Earnings of U.S. Natives Along the U.S.‐Mexico Border*

Objective. This study explores whether the earnings of U.S.‐born cross‐border workers differ from those of their U.S.‐employed counterparts. We also analyze whether the cross‐border/non‐cross‐border wage differential changed during the 1990s—a decade when U.S.‐Mexico trade intensified and the maquiladora industry expanded. Methods. Employing decennial U.S. Census data from 1990 and 2000, this article estimates earnings functions and uses wage decomposition analysis to study changes in the earnings of U.S.‐born Hispanic and non‐Hispanic cross‐border workers. Results. The number of U.S.‐native cross‐border workers, while relatively small, increased significantly between 1990 and 2000, as did their earnings. A closer examination reveals that this cross‐border earnings premium only developed among non‐Hispanics. Conclusions. These findings indicate that some U.S. natives find lucrative employment opportunities on the Mexican side of the border, which might be diminished by additional restrictions for U.S.‐born residents to easily cross back and forth into Mexico.     

Assessing the Role of Tourism in Poverty Alleviation: A Research Agenda

Understanding the tourism‐poverty link is critical if tourism is to be used as a mechanism for reducing poverty. Yet, the available empirical analysis is insufficient for this. This article proposes a research agenda for closing this gap in the literature. It argues that, while analysing the link poses peculiar challenges, models exist to do so. Second, it contends that the key question is not whether the link exists but under what conditions it is strongest. Finally, it maintains that the best way to analyse the link is to incorporate accurate diagnosis and evaluations into tourism projects, using the approaches and concepts of the literature on impact evaluation.     

Mexican Immigrant Self‐Employment Along the U.S.‐Mexico Border: An Analysis of 2000 Census Data*

Objective. This study explores the entrepreneurial tendencies of Mexican immigrants in metropolitan statistical areas (MSAs) on the U.S. side of the Mexican border vis‐à‐vis the U.S. interior. Methods. Using 2000 Census data available in the 5% Integrated Public Use Microdata Series, we empirically analyze the self‐employment rates and earnings of Mexican immigrants residing in U.S. cities near Mexico versus those in nonborder MSAs. Results. Our findings indicate that Mexican immigrants in MSAs along the U.S.‐Mexico border have significantly higher self‐employment rates (but lower earnings) than their counterparts in the rest of the United States and non‐Hispanic whites in border cities. Explanations for these findings include the existence of trade opportunities in U.S. border cities as well as intense labor market competition that crowds a greater share of immigrants into self‐employment. Conclusion. Immigration reform that curtails the immigration flow from Mexico might hinder small business formation and economic development on the U.S. side of the Mexican border.     

Corporate ownership,efficiency and performance under state capitalism: Evidence from China

This paper studied the relationship between business performance and the ownership structure of firms focusing on Chinese state owned enterprises (SOEs) using a firm level panel data set of China from 1999 to 2011. By classifying all firms into different types based on their ultimate controlling shareholders, we found that SOEs in general underperform in the marketplace than private enterprises. However, among the SOEs in our sample, the SOEs controlled by central government outperformed all types of firms because they offered the highest asset turnover ratio and lowest business administration ratio by receiving favourable government treatment. We conclude that firm ownership type and work efficiency are the main factors that influence the differences in firm performance. In particular, the performance of SOEs controlled by central government is greatly determined by the degree of government intervention, which is referred to as State Capitalism.     

The Value Relevance of Fair Value

This paper investigates the value relevance of revalued tangible assets and its variation depending on industry, size of the firm and age of revalued amounts. It examines the reaction of investors on the Romanian market, a developing market, in the period of economic growth between 2003 and 2007, before Romania’s adherence to the European Union. Also, it suggests a model which allows for the comparative analysis of the influence over share price attributed to two equity growth sources: revaluation reserves and operational profit. The findings confirm the central hypothesis of the study—revaluated amounts of tangible assets are value relevant—and verify the predictive and feedback value, timeliness, reliability, and the possibilities for fair value implementation, characteristics which have been selected for testing. However, the results are less consistent than the outcome of the variable which reflects the equity growth due to profit, which leads to a moderate value relevance of fair value in the case of revaluated tangible assets. The value relevance analysis on clusters verifies the established hypotheses regarding the superiority of value relevance for the manufacturing sector as opposed to the service sector and of revaluations older than 2 years compared to more recent revaluations. The hypothesis regarding higher value relevance of revaluated amounts disclosed by large firms compared to SMEs is not confirmed, as only the latter presented significant statistical values.     

The Marital Status of Recent Mexican Immigrants in the United States in 1980 and 19901

Using Public Use Microdata Samples, we analyze the temporal marriage patterns of recent Mexican immigrants in the United States, and relate these patterns to socioeconomic and political events, such as U.S. immigration reform, increasing returns to skill, and rising incentives for unattached Mexicans to migrate during the 1980s. Our findings indicate that recent Mexican immigrants (particularly men) were less likely to be married within five years of migrating in 1990 than their counterparts had been in 1980. An empirical extension further suggests that the relative endogamy odds among Mexican immigrants who migrated to the United States by 1980 increased during the next decade. Such demographic changes may affect policies involving issues such as education, welfare and retirement.
