A Survival Analysis of Timing of Entry into Prostitution: The Differential Impact of Race, Educational Level, and Childhood/Adolescent Risk Factors

Using survey data obtained from 309 women working in street-level prostitution in Phoenix, Arizona, this investigation examines the influence of minority status, educational level, and the experience of risk factors in an individual's childhood or adolescence on the hazard rate for age of entry into prostitution. Findings of this study show that women engaging in prostitution have limited educational backgrounds and often do not complete high school. Results indicate that both white and minority women engaging in prostitution experienced high rates of physical and sexual abuse in childhood, as well as parental substance abuse. When compared to minority women, white women are more likely to have experienced any one of these three risk factors thought to influence entry into prostitution, yet event-history analysis indicates that minority women consistently experience significantly higher hazard rates for entry into prostitution. Findings suggest the need for future research to better assess the impact of race—in the form of socioeconomic and social disadvantages associated with minority status—as it relates to entry into the sex trade.     

Prices,Markups, and Trade Reform

This paper examines how prices, markups, and marginal costs respond to trade liberalization. We develop a framework to estimate markups from production data with multi‐product firms. This approach does not require assumptions on the market structure or demand curves faced by firms, nor assumptions on how firms allocate their inputs across products. We exploit quantity and price information to disentangle markups from quantity‐based productivity, and then compute marginal costs by dividing observed prices by the estimated markups. We use India's trade liberalization episode to examine how firms adjust these performance measures. Not surprisingly, we find that trade liberalization lowers factory‐gate prices and that output tariff declines have the expected pro‐competitive effects. However, the price declines are small relative to the declines in marginal costs, which fall predominantly because of the input tariff liberalization. The reason for this incomplete cost pass‐through to prices is that firms offset their reductions in marginal costs by raising markups. Our results demonstrate substantial heterogeneity and variability in markups across firms and time and suggest that producers benefited relative to consumers, at least immediately after the reforms.     

Aus der Praxis: Erfolgsfaktoren der Post-Merger Integration

The article describes the internationalization process of a Facility Management company. Five key factors for success have been identified: new perspectives for employees, maintenance of independency + homogenization of structures, transparency, internationalization of management and formation of a common identity. The role of organization development in this process and future challenges for post-merger integration are depicted.     

Wirkprinzipien handlungsorientierter Beratungs- und Trainingsmethoden

The article suggests effect principles of action-oriented methods for organizational counselling and training. It is shown that action-oriented methods use “surplus reality” (a concept developed by J. L. Moreno) as a constitutive medium in which they duplicate organizational reality by means of scenic embodiment. The authors show how action-oriented methods derive their specific potential for the depiction and reflection of work-related problems in organizational counselling, training, supervision and coaching from this surplus reality.     

Quality of life after radiation therapy: A study of 309 cancer survivors

(1) Comparison of patients with a national sample reveals no difference in income (adjusted for inflation), marital status and education level but patients, who are typically older, are more often retired or disabled. (2) Overall, perceived quality of life is nearly the same for patients and national sample; apparent differences can be readily explained by factors other than cancer or its treatment. (3) While some minor differences among patients were found as a function of their site of cancer, treatment modality, or health status, no evidence was found of significant detrimental effects due to radiation therapy or perceived quality of life. (4) Contrary to expectations of deteriorated quality of life, compared to the national baselines the patients are actually more satisfied with their lives as a whole.     

Children's Economic Roles in the Maya Family Life Cycle: Cain,Caldwell, and Chayanov Revisited

This article examines the relationship between household demographic pressure and interage transfers for a group of Maya subsistence agriculturists in Yucatán, Mexico. The authors use data from a field study conducted in 1992–93 on individual time allocation, relative productivity by age and sex, and caloric costs of activities to estimate age schedules of average consumption and production. Using these, they investigate the net costs of children to their parents and find that children have a negative net asset value up to the time they leave home. The direction of net wealth flows in this group is downward, from older to younger, and in economic terms the internal rate of return to children is highly negative up to the time they leave home. Nonetheless, children play a critically important role in the family's economic life cycle. On average, girls offset 76 percent of their consumption costs before leaving home at age 19, and boys offset 82 percent before leaving home at 22. Without the contributions from children as a group, parents would have to double or triple their work effort during part of the family life cycle if they were to raise the same number of children. By the thirteenth year of the family life cycle, children as a group produce more than half of what they consume in every year, and after the twentieth year children produce more than 80 percent of what they as a group consume. The authors also find that the elderly in the sample, ages 50 to 65, produce more than they consume. Thus while children have a negative net asset value to parents, the timing of their children's economic contribution across the family life cycle plays a key role in underwriting the cost of large families.     

The Subjective Well-Being of Immigrants: Pre- and Post-migration

In recent years, migration studies have increasingly shown that subjective well-being carries considerable weight in immigrant integration. Yet little is known about the subjective well-being of immigrants in their origin country (pre-migration) or its relation to their well-being in the host country. This paper examines the relationship between subjective well-being, both pre- and post-immigration, among North Americans who arrived in Israel during the past two decades. The study combines both quantitative and qualitative research methods. According to our quantitative findings, the labor market performance of North American immigrants in Israel is lower than in their origin countries. Further, we learned from the qualitative analysis that although the immigrants’ positions in the labor market were better in their origin countries, the immigrants perceived their standard of living in Israel to be the same as in their origin country—if not better—due to the low cost of services in Israel. The importance of the immigrant’s satisfaction from the current job in Israel was apparent in the findings of both methods. We also found that the subjective well-being of North American immigrants in Israel is relatively high, and most immigrants did not consider leaving Israel. The subjective well-being of the immigrants in Israel was found to be related to their social networks in their origin country, to their religious immigration motive and to their work satisfaction in Israel. The more supportive the immigrants’ families were of their decision to immigrate, the less the immigrants tended to consider leaving Israel. Immigrants with a religious motivation for immigrating to Israel were less inclined to leave, and the same was true for immigrants who were satisfied with their work in Israel. The qualitative data added important perspective on the immigrants’ social networks, this time in Israel. Interviewees reported having more supportive social networks in Israel, and a greater sense of community, although most of their contacts were within the Anglo community.     

A Fairly Accurate Approximation to the Area Under Normal Curve

In this article, we present a new approximation to the cumulative distribution function of standard normal distribution. The approximation is fairly accurate with minimum accuracy of seven decimal digits. To the best of our knowledge, this formula outperforms other such approximations available in literature.     

Comparison of Poverty and Income Disparity of Single Mothers and Fathers Across Three Decades: 1990–2010

As the potential for more children being raised by single parents increases, so does the societal need to examine this phenomena of single parent earnings and the impact it will have on the ability to support a family above the poverty line. Research suggests a substantial pay gap between men and women, but most research is limited to individuals in traditional families. This study explores income disparity and poverty between single mothers and single fathers across three decades (1990–2010), using a US nationally representative sample. Based on human capital theory, our analysis reveals that single mothers were more likely to be in poverty at far greater rates than single fathers, after controlling for a host of demographic, human capital, and work related variables. We also found that a contributing factor to this disparity is that single mothers were penalized for having more children while single fathers were not. We find that gendered poverty and the gender pay gap narrowed between 1990 and 2000, but have stayed stable since. Overall, human capital decreases the gender income and poverty gap, but a substantial gap still remains. Implications for policy-makers are discussed.
