Nearly since the first automobile traveled on U.S. soil, questions about how best to compensate people injured by their use have been raised. As early as in 1932, in fact, the tort system of imposing costs on negligent drivers was strongly criticized, and a system of compensation without regard to negligence recommended. Yet despite various efforts to identify and implement improved systems during the past more than 70 years, no clear best compensation mechanism has been found. Current discussions have focused on the “choice” system, under which insureds are allowed to select either a tort system or a no‐fault system of compensation at the time of insurance purchase. New Jersey and Pennsylvania, which implemented very similar choice programs in 1989 and 1990, respectively, offer an opportunity to observe the effects of choice on outcomes such as: use of attorneys, speed of payment, and consistency (equity) of payment. Our results indicate outcomes consistent with expectations in New Jersey (NJ), which switched from no‐fault to choice, but inconsistent with expectations in Pennsylvania (PA), which switched from tort to choice. Furthermore, analysis of tort versus no‐fault selectors postchoice in New Jersey and Pennsylvania does not offer clear evidence of no‐fault's lower administrative costs and speedier, more equitable payment in these jurisdictions.  相似文献

In this paper we consider the exact D-optimal designs for estimation of the unknown parameters in the two factors, each at only two-level, main effects model with autocorrelated errors. The vector of the n random errors in the observed responses is assumed to follow a first-order autoregressive model (AR(1)). The exact D-optimal designs seek the optimal combinations of the design levels as well as the optimal run orders, so that the determinant of the information matrix of BLUEs for the unknown parameters is maximized. Bora-Senta and Moyssiadis (1999) gave some conjectures about the exact D-optimal designs based on their experience of several exhaustive searches. In this paper their conjectures are partially proved to be true.Received: January 2003 / Accepted: October 2003Partially supported by the National Science Council of Taiwan, R.O.C. under grant NSC 91-2115-M-008-013.Supported in part by the National Science Council of Taiwan, R.O.C. under grant NSC 89-2118-M-110-003.  相似文献

This paper explores the effects of different types of bank ownership concentration on changes in bank risk during acquisition years. Using multi-country data from 2000 to 2006, during which market failures caused by various crises and government interventions are less influential to acquisition decisions, we collect 505 banking acquisition deals from 23 countries to examine which type of ownership concentration (such as financial intermediary, capital investor, non-financial, and state ownership) brings larger changes to an acquirer’s risk from pre-acquisition year to post-acquisition year (including non-performing loans, capital adequacy ratio, loan loss reserve, and credit rating). The empirical analyses show that acquirer banks with a concentration of shares owned by financial intermediaries and non-financial firms experience larger risk changes during acquisition years. In contrast, the risk changes of acquirer banks with a concentration of capital investors and state ownership are lower. Robustness checks from the random effect estimation, instrumental variables model, reverse causality, and different subsamples of (non-)U.S. or different levels of regulation enforcement confirm these results.  相似文献

Purpose: Backpacker tourism is flourishing in this century as the high development of Internet technology which enables travellers to search for resources they need easier. The research goal of this study was to exam how virtual skill and collective efficacy affect process innovation capability and subsequent team performance of collaborative design team in a virtual community. Design/methodology/approach: In this study, we formulated the virtual team model from the perspectives of open innovation paradigm and virtual competence, and we collected virtual community participation samples from the online communities. Invitation emails were delivered to numerous trip plan initiators in two well-known online travel communities for filling survey questionnaires for this study. In total, 3000 invitation messages were mailed, of which 373 were returned completed. The model and hypotheses were tested by structural equation modelling. Findings: Virtual competence, including collective efficacy and virtual media skill, is the essential key to facilitate process innovation capability and subsequent team performance success. Besides, knowledge sharing significantly moderates the relationship between process innovation capability and the team performance. Originality/value: Backpackers in the online travel communities have to have not only the willingness to collaborate, but also the abilities of using the correct tool to help with their tasks. When a self-efficacy gets into collective efficacy, it enables the collaborative team to develop with good virtual competencies. Accordingly, trip plan initiator and participants of a virtual team are as expertise contributors between conformity in online communities and online compulsive control tendencies.  相似文献

The service industries have experienced dramatic changes in service delivery format because of fast-paced innovation in information technology. Hybrid services involve service deliveries through conventional and technology-enabled environments, each of which is complementary and non-interchangeable. However, limited research has examined consumer behavior in response to a series of relevant service episodes in different channels at different points in time. In other words, how customers perceive service quality at each service encounter and how the cumulative effect of these perceptions influences customers’ overall service value assessment and satisfaction remain unclear. This study addresses this research gap by investigating the sequential influence of e-service quality on in-person service quality in a hybrid service format in which interpersonal and computer-mediated services coexist but at different points in time. Empirical analysis shows that e-service quality directly and positively affects in-person service quality, which fully mediates the effects of e-service quality on perceived value and customer satisfaction. The sequence of service encounters matters because in-person service quality perception has a stronger effect than e-service quality on customer metrics. Cumulative quality perceptions significantly influence perceived value and overall customer satisfaction. Theoretical and managerial implications are presented in the discussion.  相似文献

The purpose of this study threefold: to determine whether a shared cultural model of the importance of a set of leisure activities to a good leisure life existed in urban Taiwan, the degree to which cultural consonance in leisure mediates the relationship between leisure constraints and leisure satisfaction, and the degree to which leisure satisfaction affects life satisfaction and self-rated health. Results indicate that a cultural model of the importance of leisure activities to a good leisure life existed among sample members. Second, higher levels of self-reported participation in leisure activities that are culturally agreed upon as more important for a good leisure life are more strongly associated with leisure satisfaction than are activities culturally agreed upon as less important. Finally, leisure satisfaction strongly predicts both life satisfaction and self-rated health.  相似文献

Finding a precise variance–covariance matrix is the building block of empirical finance. While microstructure-noise-robust methods for realized volatility are in the mainstream of financial econometrics, little if any attention has been devoted to estimating a noise-free realized covariance for overlooking the well-documented manifestation of commonality in market microstructure factors such as order flows, liquidity or herding. By documenting and recognizing this fact, we propose a microstructure-noise-free nonparametric covariance estimator to uncover the virtual integrated covariance. The estimator is easy to implement and performs admirably.  相似文献

This paper explores whether policy coordination or a single monetary policy implemented earlier would have kept the U.K. in the process of European monetary integration. On the basis of the pre-ERM crisis empirics by Douven and Plasmans (1996), a counterfactual game simulation approach is used, and five scenarios are established for comparison with the actual historical records. The final answer is negative.  相似文献

Using principal component analyses, this paper constructs two internationalization indices for the renminbi (RMB) and 32 other major currencies. We find that the RMB's currency internationalization degree index (CIDI) is still low, and far behind the 4 most important international currencies. In 2009, it was ranked 18th among all important international currencies. However, in terms of the currency internationalization prospect index (CIPI), the RMB has remained the world's fifth highest since 2006. Although it is still far behind the US dollar and the euro, surpassing the ranking of the yen and the pound is possible in the near future. The dramatic difference in the ranking between the CIDI and the CIPI is a result of China's tight capital account control, the usage continuity of international currency due to network externalities, and the narrow foreign exchange and imperfect financial markets. Hence, to a large degree, the RMB's potential as an international currency depends on China's capital account liberalization.  相似文献

We discuss a mixed methodology for analyzing pile sorting data. We created a list of 14 barriers to colon cancer screening and recruited 18, 13, and 14 participants from three American Indian (AI) communities to perform pile sorting. Quantitative data were analyzed by cluster analysis and multidimensional scaling. Differences across sites were compared using permutation bootstrapping. Qualitative data collected during sorting were compiled by AI staff members who determined names for the clusters found in quantitative analysis. Results showed five clusters of barriers in each site although barriers in the clusters varied slightly across sites. Simulation demonstrated type I error rates around the nominal 0.05 level whereas power depended on the numbers of clusters, and between and within cluster variability.  相似文献
