Although consumer-driven health plans (CDHPs) have grown dramatically, the question of whether CDHPs have reduced health care costs has not been answered definitively. This article presents what the authors believe to be the first study to analyze a large sample of claims data and to look in detail at different types of utilization among enrollees in a CDHP and those in a traditional comprehensive major medical (CMM) plan. After adjusting for the finding that CDHP enrollees are both younger and healthier than those in CMM plans, the authors found that CDHP enrollees show no consistent or significant utilization differences for measures over which consumers have little control (e.g., inpatient stays); lower utilization for measures over which consumers have greater control (e.g., emergency room visits); and higher utilization of preventive services. 相似文献

The Rosse–Panzar revenue test for competitive conditions in banking is based on observation of the impact on bank revenue of variation in factor input prices. We identify the implications for the H-statistic of misspecification bias in the revenue equation, arising when adjustment towards market equilibrium is partial and not instantaneous. In simulations, fixed effects estimation produces a measured H-statistic that is severely biased towards zero. Empirical results for the banking sectors of the Group of Seven (G7) countries corroborate our principal finding, that a dynamic formulation of the revenue equation is required for accurate identification of the H-statistic. 相似文献

Recent years have witnessed a wave of consolidation amongst US credit unions. Through hazard function estimations, this paper identifies the determinants of acquisition for credit unions during the period 2001-06. The hazard of acquisition is inversely related to both asset size and profitability, and positively related to liquidity. Growth-constrained credit unions are less attractive acquisition targets. Institutions with low capitalization and those with small loans portfolios relative to total assets are susceptible to acquisition. The investigation presents unique empirical evidence of a link between technological capability and the hazard of acquisition. During the period 2001-06, when there was sustained growth in the use of internet technology, credit unions with no website were at the highest risk of acquisition. 相似文献

We examine the role of public and private interests in the passage of major legislative bills that have governed the rail industry since 1887. Our model of voting patterns in the House and Senate introduces novel measures of industry concentration, competition, and network characteristics. We find that both the level and concentration of rail infrastructure in a state, the presence of water competition, and the level of agricultural production each have a major influence over voting patterns not only for the inception of regulation but also in the major bills that deregulated the industry in the 1970s and in 1980. 相似文献

This paper posits that the efficacy of different retrenchment strategies depends upon the firm's core rent creation mechanism. We focus on two distinct mechanisms of rent creation: Ricardian rent creation based on the exploitation of resources and Schumpeterian rent creation based on explorative capabilities. We argue that cost retrenchment may have detrimental effects on firms with a relatively high Schumpeterian rent focus. On the other hand, asset retrenchment may erode the basis for future rent creation for firms with a higher Ricardian rent focus. Our findings based on a sample of large nondiversified Japanese firms highlight the differing degrees of fragility and recoverability of the two rent creation mechanisms in the context of different retrenchment strategies.

In 2015, the Federal Communications Commission (FCC) imposed common carriage regulation—so-called Title II requirements—on previously unregulated broadband Internet service providers. The regime shift was premised on the FCC’s findings that such rules had demonstrably yielded economic gains. This paper evaluates the FCC’s empirical arguments and finds them uncompelling. Adjustments for inflation or general economic trends eliminate the effects cited by the FCC. Moreover, contrary to the Commission’s assessment, mobile services and broadband markets have shown notable growth in response to deregulatory events that reduce Title II requirements. 相似文献

Abstract Country indices as represented by iShares exhibit non-normal return distributions with both skewness and kurtosis. Earlier studies provide procedures for determining the statistical significance of stochastic dominance measures and the Sharpe Ratio. This present study uses these refinements to compare the performance of 18 country market indices. The iShares are indistinguishable when using the Sharpe Ratio as no significant differences are found. In contrast, stochastic dominance procedures identify dominant iShares. Although the results vary over time, stochastic dominance appears to be both more robust and discriminating than the CAPM in the ranking of the iShares. 相似文献

This paper tests whether poorly capitalized banks with troubled loan books are more likely to miss their bailout dividends. Privately held banks with weaker core capital ratios, more charged off loans, more allowances for loan losses, and more non-performing loans are more likely to miss their Troubled Asset Relief Program (TARP) dividends. Banks that issue non-cumulative preferred stock are also more likely to be TARP deadbeats. In addition, banks that missed a bailout dividend in the prior quarter are significantly more likely to miss the next bailout dividend. 相似文献
