DEA APPLIED TO A GAUTENG SAMPLE OF PUBLIC HOSPITALS1

The research presented in this paper provides an analysis of the delivery of a few health care services by the public sector in Gauteng, South Africa. The data for the study was especially difficult to collect, suggesting the need for hospital level data information systems, as well as staff who are trained to analyze the information collected. The empirical results from the analysis suggest that services provided by small‐scale medical facilities waste fewer resources, while medical centres offering more technical services, such as surgeries, also appear to deliver medical services more efficiently.     

Groupware adoption in a distributed organization: transporting and transforming technology through social worlds

In this paper, we draw on theory from social worlds to analyze how different organizational contexts affect groupware adoption. We report on a study of the adoption of data conferencing in a large distributed organization. Our data show that the diffusion process, which was driven by the users, was a result of communication and transformation of the technology across different social worlds. We also discovered that membership in multiple social worlds in an organization creates a tension for the potential adopter who is in a distributed team. To function effectively, team members must uniformly adopt the technology, yet some may face resistance from other social worlds to which they belong. Our study showed that adoption was affected by organizational sites having conflicting views of the value of collaboration, different amounts and needs for resources, and different acceptance of technology standards. Potential technology adopters on distributed teams are faced with conflicting loyalties, constraints, and requirements between their distributed collaborations and organizational homes.     

Do former athletes make better managers? Evidence from a partially adaptive grouped-data regression model

The goal of this paper is to introduce a partially adaptive estimator for the grouped-data regression model based on an error structure described by a mixture of two normal distributions. The model we introduce is easily estimated by maximum likelihood using the EM algorithm adapted from the work of Bartolucci and Scaccia (Comput Stat Data Anal 48:821–834, 2005). The partially adaptive estimator is applied to data used by Long and Caudill (Rev Econ Stat 73:525–531, 1991) to examine the impact of intercollegiate athletics on income. We estimate a variation of the original regression model and find that there is a considerable financial advantage for those male athletes now working in business management. This finding is consistent with the idea that athletes acquire team-building and organizational skills that are helpful in business.     

Does the Confucius Institute Network Impact Cultural Distance? A Panel Data Analysis of Cross‐Border Flows in and out of China

This paper examines the impact of cultural distance in general and the Confucius Institute Network in particular on cross‐border flows of tourists, goods and investment in and out of China. We estimate a panel gravity model of inbound and outbound flows between 2004 and 2012. We find that the presence of Confucius Institute(s) in the source country increases inbound tourism and equity flows and outbound export and FDI flows for China, while other measures of cultural distance have less of an impact.     

The Higher Earning in America: Are 529 Plans a Good Way to Save for College?

This article studies whether 529 plans are an effective way for most people to save for college. The 529 plans were created in 1996 to help low- and middle-income American families save for college. Since this time they have adopted more tax advantages and grown substantially as a result. While total balances in 529 plans now exceed $250 billion, less than 3.0 percent of households have a 529 plan. And the majority of 529 plan accounts are held by the wealthiest households. Low- and middle-income households receive little tax savings from investing in 529 plans, and some states count these plans against financial aid. Also, 529 plans are complicated, rules vary by state, and fund management fees tend to be high. Thus, 529 plans are not the panacea to college affordability.     

Common Institutional Ownership and Earnings Management*

This study examines the relation between earnings management and block ownership of same‐industry peer firms by a common set of institutional investors (common institutional ownership). This relation is important given the tremendous growth of common institutional ownership and the significant influence of blockholders on financial reporting. We hypothesize that common institutional ownership mitigates earnings management by enhancing institutions' monitoring efficiency and by encouraging institutions to internalize the negative externality of a firm's earnings management on peer firms' investments. Consistent with our hypothesis, we find that higher common institutional ownership is related to less earnings management. Analyses of a quasi‐natural experiment based on financial institution mergers show that this negative relation is unlikely to be driven by the endogeneity of common institutional ownership. Cross‐sectional tests provide evidence that the negative relation is stronger among firms for which common institutional ownership is likely to generate a greater reduction in institutions' information acquisition and processing costs, and among firms whose severe financial misstatements are more likely to distort co‐owned peer firms' investments, supporting both mechanisms underlying our hypothesis. Our findings inform the ongoing debate on the costs and benefits of common institutional ownership by highlighting an important benefit: the enhanced monitoring of financial reporting.

Personal and nonpersonal incentives in mail surveys: Immediate versus delayed inducements

A mail survey was conducted to empirically investigate contributions to charity as a method of stimulating responses to a mail survey. The research design included a control group and four experimental groups with the following treatments: a prepayment of $1.00 enclosed with the questionnaire (immediate personal reward), $1.00 promised upon return of the questionnaire with the respondent identified (delayed personal reward, no anonymity), $1.00 promised upon return of the questionnaire with no identification of the respondent (delayed personal reward, anonymity), and the promise of $1.00 contribution to a respondent-selected charity (delayed non-personal reward). The $1.00 prepayment yielded a statistically significant higher response rate than the $1.00 promised to charity or $1.00 promised upon return of the questionnaire. This study generally supports existing empirical foudnations of equity theory. An immediate personal reward yields a higher response rate than a delayed personal or non-personal reward.     

Ex ante analysis of the benefits of transgenic drought tolerance research on cereal crops in low-income countries

This article develops a framework to examine the ex ante benefits of transgenic research on drought in eight low-income countries, including the benefits to producers and consumers from farm income stabilization and the potential magnitude of private sector profits from intellectual property rights (IPRs). The framework employs country-specific agroecological–drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research. Benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits, representing 40% of total benefits across the eight countries. Further, estimated annual benefits of US$178 million to the private sector suggest that significant incentives exist for participation in transgenic drought tolerance research.
