HMO plans,self-selection and utilization of health care services

This study examines the effect of health maintenance organizations (HMOs) on the use of health care services among the privately insured, nonelderly population. To consider jointly the possible self-selection bias and high frequency of zero observations in the applied utilization measures, we accommodate the endogeneity of health plan choice decisions in the censored regression model. Using data from the 2000 Medical Expenditure Panel Survey, we find strong evidence for favourable self-selection into HMO plans. Health maintenance organization enrollment is found to encourage greater use of office-based and hospital outpatient services. Overall satisfaction with the quality of care among HMO members is relatively low compared to that among nonHMO members. These findings suggest that more effort is needed to develop management strategies in HMOs in order to contain the moral hazard in utilization and assure the quality of service provided within the network of HMO providers.     

Complete and Partial Organizing for Corporate Social Responsibility

This paper investigates different modes of organizing for corporate social responsibility (CSR). Based on insights from organization theory, we theorize two ways to organize for CSR. “Complete” organization for CSR happens within businesses and depends on the availability of certain organizational elements (e.g., membership, hierarchy, rules, monitoring, and sanctioning). By contrast, “partial” organization for CSR happens when organizers do not have direct access to all these organizational elements. We discuss partial organization for CSR by analyzing how standards and cross-sector partnerships make selective use of organizational elements. We maintain that an important feature of the increasing institutionalization of CSR—not only within businesses but also among non-governmental, governmental, and professional actors—is the rise of partial forms of organization. We discuss the contributions to this Special Issue in the context of our theorization of complete/partial organization for CSR and outline avenues for further research.     

Beyond panel unit root tests: Using multiple testing to determine the nonstationarity properties of individual series in a panel

Most panel unit root tests are designed to test the joint null hypothesis of a unit root for each individual series in a panel. After a rejection, it will often be of interest to identify which series can be deemed to be stationary and which series can be deemed nonstationary. Researchers will sometimes carry out this classification on the basis of n$n$ individual (univariate) unit root tests based on some ad hoc significance level. In this paper, we suggest and demonstrate how to use the false discovery rate (FDR)$\left(FDR\right)$ in evaluating I(1)/I(0)$I\left(1\right)/I\left(0\right)$ classifications.

Trade patterns and institutional change in East Asia

We investigate how trade patterns – institutionally intensive exports (IIX) – affect institutional quality in East Asia compared to the rest of the world, and whether the effect changed due to the Asian financial crisis. To examine this, we use panel data of 117 countries for the period 1988–2007. Our fixed effect model estimation reveals that the effect of IIX on institutional quality is negative and significant for East Asia, while the effect is insignificant for the rest of the world. The negative effect in East Asia is more pronounced for the five East Asian countries that were strongly affected by the crisis – South Korea, Indonesia, Malaysia, the Philippines and Thailand – than for other East Asian countries. Furthermore, our results reveal that the negative effect for East Asia does not change significantly after the crisis, both in the short and long term, and that improvement in institutional quality after the crisis is not different from that of the rest of the world. This suggests that the crisis had no significant impact on East Asia's institutional quality or on the effects of IIX on institutional quality.     

Impact of corporate social responsibility on brand trust and brand loyalty: Case of Uber

The purpose of this research is to investigate the structural relationship between Uber corporate social responsibility (CSR), brand trust, and brand loyalty. Stakeholder theory is the theoretical foundation of the study. The CSR subdimensions of eco-friendliness, quarantine, user privacy, user safety, and driver well-being are used. Amazon Mechanical Turk was employed for data collection. The number of observations is 405. A structural equation model was implemented to test the research hypotheses. This study demonstrated the accountability of stakeholder theory for Uber brand management by showing a significant link between quarantine, user privacy, user safety, driver well-being, brand trust, and brand loyalty. This study contributes to the literature by validating the explanatory power of stakeholder theory in the case of Uber brand management.
