Smoothed empirical likelihood confidence intervals for the relative distribution with left‐truncated and right‐censored data

The study of differences among groups is an interesting statistical topic in many applied fields. It is very common in this context to have data that are subject to mechanisms of loss of information, such as censoring and truncation. In the setting of a two‐sample problem with data subject to left truncation and right censoring, we develop an empirical likelihood method to do inference for the relative distribution. We obtain a nonparametric generalization of Wilks' theorem and construct nonparametric pointwise confidence intervals for the relative distribution. Finally, we analyse the coverage probability and length of these confidence intervals through a simulation study and illustrate their use with a real data set on gastric cancer.

Risk attitudes in a social context

Many experiments have demonstrated that when evaluating payoffs, people take not only their own payoffs into account, but also the payoffs of others in their social environment. Most of this evidence is found in settings where payoffs are riskless. It is plausible that if people care about the payoffs of others, they do so not only in a riskless context, but also in a risky one. This suggests that an individual’s decision making under risk depends on the risks others in his or her environment face. This paper is the first to test whether individuals’ risk attitudes are affected by the risks others face. The results show that risk attitudes appear to be less affected by others’ risks than expected, even though the same subjects do show concerns for inequality in a riskless setting. Interestingly, we find that people prefer risks to be independent across individuals in society rather than correlated.     

Staffing-Related Deficiency Citations in Nursing Homes

There is evidence that staffing characteristics influence quality of care in nursing homes. Federal and state surveyors conduct inspections of homes to assess their compliance with regulatory standards, including requirements related to staffing. Deficiency citations are issued when these standards are not met. This article examines the relationship between operational, facility, and market characteristics and organizational performance measured as staffing-related deficiency citations. Online Survey Certification of Automated Records (OSCAR) data from 2000 through 2007 were used with multinomial logistic regression analyses to identify factors associated with deficiency citations for staffing. Chain members and facilities with poor quality of care were more likely to receive deficiency citations for staffing. Greater bed count and competition between nursing homes were associated with a decreased likelihood of deficiency citations for staffing. Staffing-related deficiencies within nursing homes vary according to various operational, facility, and market characteristics.     

Social programs and household size: evidence from New York city

What determines how many adults live in a house? How do people divide themselves up among households? Average household sizes vary substantially, both over time and in the cross-section. In this paper, we describe how a variety of government policies affect living arrangements, intentionally or not. Using data from a survey of households in New York City, we find that these incentives appear to have an impact. Specifically, households receiving these housing and income subsidies are smaller on average (measured by number of adults). The impacts appear to be considerably larger than those that would occur if the programs were lump-sum transfers. Small average household size can be extremely expensive in terms of physical and environmental resources, higher rents, and possibly homelessness. Thus, we encourage policymakers to pay greater heed to the provisions built into various social policies that favor smaller households.     

Survey of manufacturing curricula from around the world

In the manufacturing organization cost or more specifically cost reduction is an everyday obsession with managers and engineers. To compete globally and win new contracts, manufacturing firms need to learn how to be responsive, lean and efficient. On the other hand, in order to retain and motivate workers, improve systems efficiency and conform to various regulations including health, safety and the environment, manufacturing firms need to continuously invest. Both opposing pressures create a challenging environment for manufacturing managers and engineers. This paper introduces research into how the manufacturing environment is changing and in particular the type of issues that manufacturing managers and engineers need to learn. The paper presents the first results of a study being conducted by a number of academic institutions and industries from around the world into manufacturing education issues. The principle aim of the research consortium is to anticipate the needs of manufacturing organization of the future and to provide a framework for curriculum development within universities that meet these needs. This paper specifically outlines the results of a study of existing manufacturing curricula from around the world and takes an in-depth look at four recently developed masters programmes.     

Ethnic Prejudice and Discrimination in Europe

This article provides an introduction to research on European prejudice and discrimination. First, we list the distinctive characteristics of a European perspective and provide a short sketch of European immigration and ethnic groups. Europe has become a multicultural community. Nevertheless, public opinion and the continent's politics often do not reflect this empirical fact. Prejudice and discrimination directed at immigrants are a widespread phenomena across Europe. Several cross-European surveys support this conclusion, although theoretically driven surveys on prejudice and discrimination in Europe remain rare. Cross-European research studies classical and modern theories of prejudice and discrimination and attempts to uncover the psychological mechanisms that explain individual readiness to exclude ethnic groups. A brief sketch of recent European research is presented. This issue offers both important cross-national perspectives as well as needed comparisons with the more studied case of racial prejudice and discrimination in the United States.     

Relative Deprivation and Intergroup Prejudice

Using three diverse European surveys, we test the relationship between relative deprivation (RD) and anti-immigrant prejudice. We find that both group relative deprivation (GRD) and individual relative deprivation (IRD) are found primarily among working-class respondents who are politically alienated. We also find that GRD, but not IRD, serves as a proximal correlate of prejudice. IRD's effects on prejudice are largely mediated through GRD. In addition, GRD partially mediates the effects of such distal predictors of prejudice as education and family income. Finally, blaming the victim mediates in part the GRD link with prejudice. These results lead to a socially situated path model of RD's effects on prejudice with public policy implications.     

CHOOSING (AND RENEGING ON) EXCHANGE RATE REGIMES

We use data on announced and actual exchange rate arrangements to ask which countries follow de facto regimes different from their de iure ones, that is, do not do what they say. Our results suggest that countries with poor institutional quality have difficulty in maintaining pegging and abandon it often. In contrast, many countries with relatively good institutions display fear of floating, that is, they manage more than announced, perhaps to signal their differences from those countries incapable of maintaining promises of monetary stability.

Unions and innovative activity in Germany

This study is the first attempt to investigate the influence of unions on innovative activities in Germany at the industry level. Econometric models estimated by a highly robust method and submitted to a number of specification tests indicate that trade unions do not have a negative impact on innovative activity which is measured by either the percentage of revenues spent on R&D or the percentage of employees working in R&D. This finding is consistent with evidence on the influence of unions on productivity in Germany and with considerations about the German system of industrial relations.
