A comparison of treatment effects estimators using a structural model of AMI treatment choices and severity of illness information from hospital charts

We compare the performance of various matching estimators using a novel approach that is feasible in the absence of experimental data. We estimate a structural model of hospital choices and catheterization for Medicare heart attack victims using hospital chart data on patient heterogeneity. With the estimated structural parameters, we simulate data for which the treatment effect is known. We find that as measures of individual heterogeneity are added to the controls, matching estimators perform well. However, the estimators do a poor job recovering the true treatment effect when measures of individual heterogeneity are unavailable. Copyright © 2010 John Wiley & Sons, Ltd.     

The economic burden of psoriasis with high comorbidity among privately insured patients in the United States

Objective: To evaluate the impact of comorbidities on healthcare resource use (HRU), and direct and indirect work-loss-related costs in psoriasis patients.

Methods: Adults with psoriasis (≥2 diagnoses, the first designated as the index date) and non-psoriasis controls (no psoriasis diagnoses, randomly generated index date) were identified in a US healthcare claims database of privately-insured patients (data between January 2010 and March 2017 were used). Psoriasis patients were stratified based on the number of psoriasis-related comorbidities (0, 1–2, or ≥3) developed during the 12?months post-index. All outcomes were evaluated during the follow-up period, spanning the index date until the end of continuous health plan eligibility or data cut-off. HRU and costs per-patient-per-year (PPPY) were compared in psoriasis and non-psoriasis patients with ≥12?months of follow-up.

Results: A total of 9,078 psoriasis (mean age?=?44?years, 51% female) and 48,704 non-psoriasis (mean age?=?41?years, 50% female) patients were selected. During the 12?months post-index, among psoriasis vs non-psoriasis patients, 71.0% vs 83.0% developed no psoriasis-related comorbidities, 26.3% vs 16.0% developed 1–2, and 2.6% vs 1.0% developed ≥3 psoriasis-related comorbidities. Compared to non-psoriasis patients, psoriasis patients had more HRU including outpatient visits (incidence rate ratios [IRRs]?=?1.52, 2.03, and 2.66 for 0, 1–2, and ≥3 comorbidities, respectively [all p?p?p?p?Conclusions: HRU and cost burden of psoriasis are substantial, and increase with the development of psoriasis-related comorbidities.

The state as the investor of last resort: a comparative study of banking crises in Denmark and Sweden

This article addresses the role of the state in bailouts, i.e. government objectives and measures during banking crises. Our main question concerns the incentives and measures that governments pursue in a state of a systemic banking crisis, and why they are launched. What have been the objectives and operations when a government has decided to act as an investor of last resort and take control of commercial banks? The answer is limited to cover the financial history of two countries. The study unveils government interventions in the latest crises in Denmark and Sweden, and critically analyse which objectives justified the setting up of organisations for financial stability. The two country-cases differ in terms of historical experience, context, and time-period. We compare intrinsic principles and perceptions for government intervention, with a focus on bailouts and state-owned banks. We argue that the implementation of measures dates back to the early phases of capitalism in the 19th century i.e. is part of a historical institutional pattern. The similarities shown indicate that there is an international standard for a public–private arrangement ensuring financial stability. Our results relate to the discussion of launching effective and legitimate state policies during and after a systemic banking crisis.     

Building a multi-category brand: when should distant brand extensions be introduced?

When companies plan to build multi-category brands by adding new products to their product lines, two questions loom large: (1) whether and (2) when brand extensions perceived as distant (comparatively dissimilar) from the company’s existing core line of products should be introduced. Since many real-world firms have introduced distant brand extensions, this paper focuses on the second question: when the company should introduce a distant extension within a series of other closer extensions—a decision for which there is little research-based guidance for managers. Building on theories of mental categorization, the authors argue that early (vs. late) introductions of distant brand extensions can be more beneficial for the brand. Three studies support this conclusion, demonstrating that early (vs. late) introductions of distant extensions can result in more positive final brand attitudes; that is, attitudes held after all the extensions have been introduced. This effect is driven by how easily the distant extension is integrated into consumers’ brand concepts and is moderated by overall brand positioning. Importantly, this effect on final brand attitudes is shown to influence behavioral measures of product preference and brand engagement.
