Cost comparison of continued anticoagulation with rivaroxaban versus placebo based on the 1-year EINSTEIN-Extension trial efficacy and safety results

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.     

EVA,not EBITDA: A New Financial Paradigm for Private Equity Firms

Private equity firms have boomed on the back of EBITDA. Most PE firms use it as their primary measure of value, and ask the managers of their portfolio companies to increase it. Many public companies have decided to emulate the PE firms by using EBITDA to review performance with investors, and even as a basis for determining incentive pay. But is the emphasis on EBITDA warranted? In this article, the co‐founder of Stern Stewart & Co. argues that EVA offers a better way. He discusses blind spots and distortions that make EBITDA highly unreliable and misleading as a measure of normalized, ongoing profitability. By comparing EBITDA with EVA, or Economic Value Added, a measure of economic profit net of a full cost‐of‐capital charge, Stewart demonstrates EVA's ability to provide managers and investors with much more clarity into the levers that are driving corporate performance and determining intrinsic market value. And in support of his demonstration, Stewart reports the finding of his analysis of Russell 3000 public companies that EVA explains almost 20% more than EBITDA of their changes in value, while at the same time providing far more insight into how to improve those values.     

Archetyping relationships with companion animals to understand disaster risk-taking propensity

Pets factor into the daily decision-making of many people. Importantly, various characteristics of these human–animal relationships are known to strongly influence pet owners’ risk behaviour and, consequently, their animals’ welfare during disasters. Yet, few studies have examined a range of such characteristics concurrently in order to describe risk propensity differences in these relationships. In this study, 437 Australian companion-animal (pet) owners reported human–animal relational, personality and attitudinal characteristics, to examine differences in stated tendency to act to secure their pet’s welfare whilst risking potential harm in a hypothetical disaster dilemma. Cluster analysis identified five archetypal profiles differing in relational, personality, attitude and risk-propensity characteristics, as well as in stated willingness to risk personal safety for the well-being of a pet. Results suggest that relational archetypes are an effective means of examining pet–owner risk propensity, to better understand owners’ risk-taking to protect their animals from harm during a disaster.     

School foodservice employees’ beliefs about local produce use at work and home

Sustainability practices are becoming an essential part of foodservice businesses. Schools often purchase local produce and use it in school meals as part of their sustainability efforts. School foodservice employees play an important role in the effectuation of these efforts and understanding their perceptions is important. A questionnaire was used to assess foodservice employees’ beliefs regarding the quality and benefits of local produce use in schools. Results indicate differences in employees’ perceptions regarding benefits and quality of local produce based on their perception of the importance of purchasing local produce for home use.     

MORGAN STANLEY ROUNDTABLE ON Capital Structure and Payout Policy

A group of distinguished finance academics and practitioners discuss a number of topical issues in corporate financial management: Is there such a thing as an optimal, or value‐maximizing, capital structure for a given company? What proportion of a firm's current earnings should be distributed to the firm's shareholders? And under what circumstances should such distributions take the form of stock repurchases rather than dividends? The consensus that emerges is that a company's financing and payout policies should be designed to support its business strategy. For growth companies, the emphasis is on preserving financial flexibility to carry out the business plan, which means heavy reliance on equity financing and limited payouts. But for companies in mature industries with few major investment opportunities, more aggressive use of debt and higher payouts can add value both by reducing taxes and controlling the corporate free cash flow problem. In such cases, both leveraged financing and cash distributions through dividends and stock buybacks signal management's commitment to its shareholders that the firm's excess cash will not be wasted on projects that produce low‐return growth that comes at the expense of profitability. As for the choice between dividends and stock repurchases, dividends provide a stronger commitment to pay out excess cash than open market repurchase programs. Stock buybacks, at least of the open market variety, preserve more flexibility for companies that want to be able to capitalize on unpredictable investment opportunities. But, as with the debt‐equity decision, there is an optimal level of financial flexibility: too little can mean lost investment opportunities, but too much can lead to overinvestment.     

Quantitative Methods for Evaluating the Unilateral Effects of Mergers

We describe the quantitative modeling techniques that are used in horizontal merger review for the evaluation of unilateral effects, and discuss how the 2010 Horizontal Merger Guidelines helped legitimize these methods and motivate scholarly research. We cover markets that feature differentiated products pricing, auctions and negotiations, and homogeneous products, in turn. We also develop connections between quantitative modeling and market concentration screens that are based on the Herfindahl-Hirschman Index (HHI).

     

Replicating the Levitt and Porter estimates of drunk driving

Estimates of the prevalence and risk of drinking-and-driving are a high-priority need for researchers and policymakers. Levitt and Porter (Journal of Political Economy, 2001, 109(6), 1198–1237) demonstrate how these can be recovered using publicly available information in the Fatality Analysis Reporting System (FARS). Although robust to systematic misreporting and sample selection and far cheaper to implement than surveys, their methodological innovations are largely ignored. We believe this arises partly from difficulty in replicating their results. This article identifies the underlying causes of replication failure and offers practical guidance for future implementation that takes advantage of the current structure of the FARS data.     

Conditional Mandates on Management Earnings Forecasts: The Impact on the Cost of Debt

Exploiting a unique conditional disclosure mandate on management earnings forecasts (MEFs) in China, we examine the differential effects of voluntary and mandatory MEFs on the cost of debt. We find that firms providing voluntary MEFs have lower cost of debt than do mandatory forecasters and nonforecasters. The results of the channel analyses reveal that voluntary forecasters have greater commitment to voluntary MEFs in future periods than do mandatory forecasters and nonforecasters, and the precision, accuracy, and timeliness of MEFs are higher for voluntary forecasters than for mandatory forecasters. Additional analyses show that the differential effects of voluntary and mandatory MEFs on cost of debt are stronger for voluntary forecasters operating in opaque information environments, issuing high-quality and confirming forecasts, controlled by private shareholders, and operating in highly competitive product markets. Overall, our results indicate that, compared with mandatory MEFs, voluntary MEFs are more informative for credit investors, particularly for firms facing greater information risk and operating uncertainty.     

Bargaining externalities in a privatization programme

In privatization programmes, the state commonly keeps a minority ownership stake in firms. We provide an explanation based on the externality that privatization of one firm has on the profitability of others. If this externality is negative, as with oligopolistic firms, the government can gain a strategic advantage in bargaining over the sale of one firm if it keeps an ownership share in another. We consider both the simultaneous and the sequential sale of firms. The results apply to the period in which privatization takes place, and are consistent with the delayed sale of minority ownership often observed in practice.
