Financial resource availability and corporate social responsibility expenditures in a sub‐Saharan economy: The institutional difference hypothesis

Studies done in developed economies have demonstrated a positive relationship between financial resource availability and CSR. Arguments that we term the Institutional Difference Hypothesis (IDH) drawn from the institutional literature, however, suggest that institutional differences between developed and developing economies are likely to result in different CSR implications. Integrating the logic of IDH with insights from slack resources theory, we argue that there exists a negative relationship between financial resource availability and CSR expenditures for firms in Ghana, a sub‐Saharan African emerging economy. We use lagged data from the Ghana Investment Promotion Centre and find that Return on Sales, Return on Equity, and Net Profitability were consistently associated with lower CSR expenditures. We highlight the implications of our findings for research and managers. Copyright © 2013 John Wiley & Sons, Ltd.     

Patterns of care and burden of chronic idiopathic thrombocytopenic purpura in Brazil

Aims: Although several therapeutic options are available for chronic immune thrombocytopenic purpura (cITP), little is known about the treatment of cITP in Brazil.

Materials and methods: A multi-center, retrospective chart review, observational study was designed to describe the treatment patterns, clinical burden, resources use, and associated costs for adult patients diagnosed with cITP and treated in public and private institutions in Brazil. Patient charts were screened in reverse chronological order based on their last visit post January 1, 2012. (All costs were calculated using 1.00 USD?=?3.9571 BRL, from February 2016.)

Results: Of 340 patient charts screened, 50 patients were eligible for inclusion in the study. Single-drug therapy (prednisone, dexamethasone, or dapsone) was the most commonly used treatment, followed by combination therapies (azathioprine?+?prednisone, azathioprine?+?prednisone?+?danazol, and prednisone?+?dapsone). Splenectomy was performed in 22% of patients after at least first-line treatment. Platelet count and number of bleeding episodes at diagnosis were 31,561.1/mm³ (SD?=?±26,396.1) and 40 episodes, respectively; in first-line, 92,631.1/mm³ (SD?=?±79,955.3) and 19 episodes, respectively; in second-line, 96,950.0/mm³ (SD?=?±76,476.4) and 17 episodes, respectively. Private system patients had a higher median cost compared to public system patients (USD 17.49/month, range?=?0–2,020.77 vs USD 9.51/month, range?=?0–192.64, respectively).

Limitations: This study does not allow conclusions for causal explanations due to the cohort study design, and treatment patterns represent only the practices of physicians who have agreed to participate in the study.

Conclusions: The data indicate that available therapeutic strategies for second- and third-line therapies appear to be limited.     

Interconnection in Network Industries

Recent deregulation of telecommunications in the U.S. and elsewhere has highlighted the importance of interconnection in network industries. In this paper, we analyse interconnection in a deregulated network where the participants compete in the final retail market. We consider both the case of a mature industry as well as one where a new entrant challenges the incumbent. In the later case, network externalities allow the incumbent to use the terms of interconnection to maintain its dominant position. Moreover, in either case, competition in the retail market can be undermined by collusion over access prices. We discuss the implications for some of the provisions of the new U.S. Telecommunications Act, specifically mandatory interconnection and reciprocity of tariffs, comparing these to the simple bill and keep rule.     

The use of the comparable firm approach in valuing Australian IPOs

Despite the difficulty of finding comparable firms in a less populated market, we provide evidence on the usefulness of the comparable firm approach using 275 Australian industrial IPOs from 1993 to 2000. We show that, without adjustments, IPO price-earnings (P/E) and market-to-book (P/B) multiples based on management forecasts of earnings and book values of equities provided in prospectuses are strongly associated with the average P/E and P/B multiples of two comparable firms (matched on industry, growth and size). Additional tests show that the value estimated using the comparable firm approach (in the form of a P/V ratio, where P is the offer price and V is the estimated firm value) is associated with IPO underpricing.     

Research returns redux: a meta-analysis of the returns to agricultural R&D

A total of 289 studies of returns to agricultural R&D were compiled and these provide 1821 estimates of rates of return. After removing statistical outliers and incomplete observations, across the remaining 1128 observations the estimated annual rates of return averaged 65 per cent overall — 80 per cent for research only, 80 per cent for extension only, and 47 per cent for research and extension combined. These averages reveal little meaningful information from a large body of literature, which provides rate-of-return estimates that are often not directly comparable. This study was aimed at trying to account for the differences. Several features of the methods used by research evaluators matter, in particular assumptions about lag lengths and the nature of the research-induced supply shift.
