This paper analyses governance structures used to organize partnerships in R&D networks using two approaches: transaction costs theory and social capital theory. We argue that these theories are complementary; this explains forms of governance through the degrees of administrative (structural and safeguard mechanism) and social factors (cohesion and openness) they embody. Data was obtained from European R&D networks created through Framework Programmes which include a great number of universities, non profit institutions and firms. Findings show the variables that characterize and explain the governance forms based on the applicability of R&D networks. This study not only provides a theoretical model for analysing governance structures of these networks, but is also useful for both improving the management of networks and for fostering collaboration at an international level.  相似文献

This article analyzes the Supreme Court's decision in Bragdon v. Abbott to determine whether the Court's reading of ADA necessarily leads to the conclusion that a group health plan's or insurer's exclusion or limitation of coverage with respect to infertility is prohibited by ADA. The authors conclude that it may be advisable for plans to perform at least minimal actuarial calculations with respect to the current or anticipated costs of covering infertility treatments prior to adopting any exclusions or limitations of coverage.  相似文献

Many employer-sponsored health plans and multi-employer health benefit trusts have seen an increase in medical child support orders (MCSOs), and they can anticipate receiving a greater number in the future. Once regulations are final for the national medical support notice (NMSN) required by the Child Support Performance and Incentive Act of 1998, plans should also begin receiving these. In preparation, plan administrators should ensure that they have proper procedures in place for determining whether MCSOs and NMSNs constitute QMCSOs.  相似文献

Abstract

Aims

To characterize a US population of patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) using CONTOR, a real-world longitudinal research platform that deterministically linked administrative claims data with patient-reported outcomes data among patients with these conditions.  相似文献

Self‐selection in rural–urban migration is examined using three datasets from rural and urban China in 2002. We construct a migrant sample including both migrants who converted their hukou status from rural to urban (permanent migrants) and those who did not (temporary migrants). We find a strong positive selection for permanent migrants, but the selection for temporary migrants is ambiguous. We reach these conclusions by comparing migrants' counterfactual wage densities, assuming they are paid as rural local workers, to actual wage densities of rural local workers. Our results imply that permanent migration has negative effects on rural human capital accumulation and income levels.  相似文献

A new multi-logistic methodology to analyze long range time series of evolutionary S-shaped processes is presented. It conceptually innovates over the traditional logistic approach. The ansatz includes computing the residuals to an optimized multi-logistic trend curve least squares fitted to the time-series data. The elements of the residuals series are checked for autocorrelations and once detected the residuals series is further analyzed to search for eventual presence of underlying periodic structures using a truncated Fourier sine series. The method foundations ensures both a universal applicability and a capacity to disclose the existence of active clocks that can be possibly traced to the driving motors of the evolutionary character of the time series, due to the responsiveness of corresponding process to the development of economic cycles. On associating these two views, it is found that the methodology has a strong potential to improve the quality of short-term forecasts. These findings have been put to test through applications of the methodology to studying the time evolution of two commodities of strong economic and social importance (corn and steel) and good results were consistently obtained for both the analytical and forecasting aspects.  相似文献

This paper develops a simple spatial model of fundraising, in which charities select a target population to solicit donations. First, we show that in a competitive charity market without any intervention, the number of charities in the market and/or the overall net funds raised by charities may be suboptimal. Next, we analyze whether a social planner can prevent such shortcomings and show that a regulatory mechanism can be designed to achieve socially desirable outcomes. In contrast to the previous literature, our model does not necessarily produce monopoly as the optimal market structure. We show that if fixed costs associated with establishing charities are sufficiently low, then the optimal market structure is not a monopoly. Given the importance of the trade‐off between the volume and variety of charitable services, we argue that this result may be of particular interest to policy makers.  相似文献

This article explains how economic analysis can be applied to understand environmental problems and to suggest appropriate policies to deal with these problems. Economic analysis is performed using static and dynamic models, and one‐person and several‐person game theoretical models. Policy recommendations include the control of industrial pollution in China and the regulation of world CO2 emission through the application of a resolution by the United Nations.  相似文献
