Aims: The EINSTEIN-Extension trial (EINSTEIN-EXT) found that continued treatment with rivaroxaban for an additional 6 or 12 months (vs placebo) after 6–12 months of initial anticoagulation significantly reduced the risk of recurrent venous thromboembolism (VTE) with a small non-significant increased risk of major bleeding (none fatal or in critical site). This study aimed to compare total healthcare cost between rivaroxaban and placebo, based on the EINSTEIN-EXT event rates.Methods: Total healthcare cost was calculated as the sum of treatment and clinical event costs from a US managed care perspective. Treatment duration and event rates were obtained from the EINSTEIN-EXT study. Adjustment on treatment duration was made by assuming a 10% non-adherence rate. Drug costs were based on wholesale acquisition costs. Cost estimates for clinical events (i.e. recurrent deep vein thrombosis [DVT], recurrent pulmonary embolism, major bleeding, clinically relevant non-major bleeding) were determined from the literature. Results were examined over a ±20% range of each cost component and over 95% confidence intervals (CIs) of event rate differences in deterministic (one-way) and probabilistic sensitivity analyses (PSA).Results: Total healthcare cost was $1,454 lower for rivaroxaban-treated (vs placebo-treated) patients in the base-case, with a lower clinical event cost fully offsetting drug cost. The cost savings of recurrent DVT alone (–$3,102) was greater than drug cost ($2,723). Total healthcare cost remained lower for rivaroxaban in the majority (73%) of PSA (cost difference [95% CI]?=?–$1,454 [–$2,396, $1,231]).Limitations: This study was conducted over the 1-year observation period of the EINSTEIN-EXT trial, which limited “real-world” applicability and examination of long-term economic impact. Assumptions on drug and clinical event costs were US-based and, thus, not applicable to other healthcare systems.Conclusions: Total healthcare costs were estimated to be lower for patients continuing rivaroxaban therapy compared to those receiving placebo in VTE patients who had completed 6–12 months of VTE treatment. 相似文献

The deregulation of foreign banks in Japan, although corresponding in broad outline to world-wide trends, has diverged substantially in many particulars from patterns seen elsewhere. It has tended to be excruciatingly slow and piecemeal and to have been of minimal benefit to foreign banks. A review of this process leads to the conclusion that these characteristics result from organisational and political-bureaucratic factors inherent to the Japanese style of government which is, in turn, partially a reflection of Japanese culture. Although these non-economic factors have influenced the specific pattern of change, its overall direction appears to have been consistent with the broader national interest.The authors wish to acknowledge financial support from the Social Science and Humanities Research Council of Canada, the Florsheimer Center for Policy Studies, and the Krueger Center for Financial Research. 相似文献

Exit Options in Corporate Finance: Liquidity versus Incentives 总被引:2,自引:0,他引:2
This paper provides a first study of the optimal design of active monitors'exit options in a problem involving a demand for liquidity and costly monitoring of the issuer. Optimal incentives to monitor the issuer may involve restricting the monitor's right to sell her claims on the firm's cash-flow early. But the monitor will then require a liquidity premium for holding such an illiquid claim. In general, therefore, there will be a trade off between incentives and liquidity. The paper highlights a fundamental complementarity between speculative monitoring in financial markets (which increases the informativeness of prices) and active monitoring inside the firm: in financial markets where price discovery is better and securities prices reflect the fundamentals of the issuer better, the incentive cost of greater liquidity may be smaller and active monitoring incentives may be preserved. The paper spells out the conditions under which more or less liquidity is warranted and applies the analysis to shed light on common exit provisions in venture capital financing. 相似文献

Demand fluctuations and capacity utilization under duopoly 总被引:4,自引:0,他引:4
Summary. This paper studies the impact of uncertain demand on firms’ capacity decisions when they operate in an oligopolistic environment.
We define a two-stage game where firms choose capacity in the first stage without knowing which state of Nature is going to
realize, and output levels in the second, knowing which state is realized. We prove the existence of a symmetric subgame perfect
equilibrium at which firms are in excess capacity compared with the capacity they would choose in the Cournot certainty equivalent
game.

In this paper we analyze the properties of price equilibria in a duopoly market where firms sell vertically differentiated products, consumers being uncertain about which firm sells which quality. Both existence and properties of price equilibria are characterized by the beliefs of the consumers' population about the distribution of quality between firms. 相似文献

This paper presents MAcMap–HS‐6, a database providing a consistent, ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six‐digit level of the Harmonized System (5111 products), accounting for all preferential agreements. We describe the methodology used to compute and aggregate an ad valorem equivalent of applied protection. Emphasis is placed on minimizing the endogeneity bias in the aggregation procedure, while acknowledging structural differences in export specialization. The resulting quantitative assessment is illustrated by giving an overview of applied protection across the world in 2001, in terms of average as well as distribution. 相似文献

This study investigated how partners' self-reported opportunism and shared decision making varied by culture in international joint ventures (IJVs) with the Japanese. Data were gathered by a mail survey of senior officials in IJVs located in 11 host countries. Significant differences were found between partners from Western cultures and the Japanese, but not between other Asians and the Japanese. Indirect effects suggest that shared decision making neutralizes cultural tendencies toward opportunism. Results indicated that opportunistic tendencies did not diminish as the IJV relationship aged, and that shared decision making did diminish as the relationship aged. 相似文献

This study analyzes the performance effects of proprietary, multihospital systems. It is shown that the organizational structure of these systems may affect the operating costs of member hospitals. Estimating a cost function for Florida hospitals and controlling for other factors, the average costs of HUMANA hospitals are empirically about 17 percent lower, while the costs of other leading chains are about 12 percent lower than not-for-profit institutions. These results contrast with earlier studies that found no such differences. Furthermore, the cost differential that exists between system and non-system hospitals can be largely attributed to technical efficiencies arising from chain ownership. 相似文献

E-commerce not only has tremendous potential for growth but also poses unique challenges for both incumbents and new entrants.
By examining drivers of firm performance in e-commerce from a capabilities perspective, the authors conceptualize three firm
capabilities that are critical for superior firm performance in e-commerce: information technology capability, strategic flexibility,
and trust-building capability. The extent and nature of market orientation is conceptualized as a platform for leveraging
e-commerce capabilities. The authors test the effects of e-commerce capabilities on performance (e.g., relative profits, sales,
return on investment) using data from 122 e-brokerage service providers. The results indicate that information technology
capability and strategic flexibility affect performance given the right market orientation.

Free Entry under Uncertainty 总被引:1,自引:0,他引:1
When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation and show that the impact of uncertainty will increase the number of firms in an industry. With increased uncertainty, the risk premium of the marginal buyer increases by more than the risk premium of the average buyer, so that the price increases by more than the risk premium. When turning to the free entry game, we find that the market generates too many firms. 相似文献
