UNIVERSAL BANKING: The view from Brazil

This note begins with a brief summary of the economic and regulatory history surrounding the Universal Banking debate. Following this introduction, it focuses on the Brazilian regulatory and supervision experience. The Central Bank of Brazil has persistently enhanced prudential regulation and supervision practices in order to cope with the complexity of large financial institutions and financial holding companies. Some features of the Brazilian regulatory framework have contributed to the Brazilian economic and financial performance in recent years, such as: consolidated financial statements, including all financial and non financial subsidiaries; internal structures for risk management; responsibilities for controlling shareholders; unrestricted access to all information by supervisors; and, one of the most important issues, the requirement to foreign firms to constitute stand-alone subsidiaries. Finally, there is a short overview of the G20 financial sector reform agenda (including Basel III accord), specially, regarding the issue of Systemically Important Financial Institutions – SIFIs.     

Estimating Armington elasticities for sawnwood and application to the French Forest Sector Model

Domestic and foreign forest products consumptions are considered imperfectly substitutable in the French Forest Sector Model (FFSM). This assumption is justified by product heterogeneities that depend on production places, by the consumers habits or by the market structure. It leads us to implement the international trade in the FFSM via the Armington's theory of the demand for products distinguished by place of production. In this paper we propose a calibration of Armington's elasticities of substitution between French and foreign forest products. System-GMM estimators are applied to identify robust parameters using a panel data from France customs service.     

The Monetary Analysis of Hyperinflation and the Appropriate Specification of the Demand for Money

Abstract. This paper emerges from the failure of the traditional models of hyperinflation with perfect foresight. Insights from two standard optimizing monetary settings and economic reasoning from case studies of extreme hyperinflation episodes provide relevant requirements for the specification of the demand for money during hyperinflation. The paper demonstrates that the possibility of perfect foresight monetary hyperinflation paths depends robustly on the essentiality of money. The essentiality of money provides some depth of explanation of the reasons why the popular semi‐log schedule of the demand for money is not appropriate for analysing monetary hyperinflation with perfect foresight. The paper proposes a simple test of money essentiality for the appropriate specification of the demand‐for‐money equation in empirical studies of hyperinflation.     

Ethical Cultures in Large Business Organizations in Brazil, Russia, India, and China

This study focuses on comparison of perceptions of ethical business cultures in large business organizations from four largest emerging economies, commonly referred to as the BRICs (Brazil, Russia, India, and China), and from the US. The data were collected from more than 13,000 managers and employees of business organizations in five countries. The study found significant differences among BRIC countries, with respondents from India and Brazil providing more favorable assessments of ethical cultures of their organizations than respondents from China and Russia. Overall, highest mean scores were provided by respondents from India, the US, and Brazil. There were significant similarities in ratings between the US and Brazil.     

On the Use of the Log CAR Measure in Event Studies

Cross-sectional averages of log returns have been used to measure shareholder wealth effects in several event studies. No adequate explanation of the implied portfolio strategy has ever been provided in the literature. We argue that the method is biased or does not portray a realistic portfolio strategy. It should therefore be used with caution in the event-study' literature.

Budesonide with multi-matrix technology as second-line treatment for ulcerative colitis: evaluation of long-term cost-effectiveness in the Netherlands

Aims: Budesonide with multi-matrix technology (MMX) is an oral corticosteroid, shown to have high topical activity against ulcerative colitis (UC) while maintaining low systemic bioavailability with few adverse events. The aim of this study was to evaluate the cost-effectiveness of budesonide MMX versus commonly used corticosteroids, in the second-line treatment of active mild-to-moderate UC in the Netherlands.

Materials and methods: An eight-state Markov model with an 8 week cycle length captured remission, four distinct therapy stages, hospitalization, possible colectomy and mortality. Remission probability for budesonide MMX was based on the CORE-II study. Population characteristics were derived from the Dutch Inflammatory Bowel Disease South Limburg cohort (n?=?598) and included patients with proctitis (39%), left-sided (42%) and extensive disease (19%). Comparators (topical budesonide foam and enema, oral budesonide and prednisolone) were selected based on current Dutch clinical practice. Treatment effects were evaluated by network meta-analysis using a Bayesian framework. Cost-effectiveness analysis was performed over a 5 year time horizon from a societal perspective, with costs, health-state and adverse event utilities derived from published sources. Outcomes were weighted by disease extent distribution and corresponding comparators.

Results: Budesonide MMX was associated with comparable quality-adjusted life year (QALY) gain versus foam and oral formulations (+0.01 QALYs) in the total UC population, whilst being cost-saving (EUR 366 per patient). Probabilistic sensitivity analysis evaluated an 86.6% probability of budesonide MMX being dominant (cost-saving with QALY gain) versus these comparators. Exploratory analysis showed similar findings versus prednisolone.

Limitations: Differing definitions of trial end-points and remission across trials meant indirect comparison was not ideal. However, in the absence of head-to-head clinical data, these comparisons are reasonable alternatives and currently offer the only comparison of second-line UC treatments.

Conclusions: In the present analysis, budesonide MMX was shown to be cost-effective versus comparators in the total UC population, for the second-line treatment of active mild-to-moderate UC in the Netherlands.     

Liquid retail: cultural perspectives on marketplace transformation

ABSTRACT

Inspired by Bauman’s notion of “liquidity,” we problematize the socio-cultural dynamics taking place in contemporary retail. The notion of liquid retail enables researchers to untangle marketplace transformation and to highlight developments centred around markets and market-actors that jointly transform each other. This introduction underlines, as a point of departure, recent developments in retailing that have been marked by the corrosion of fixity and boundaries. We provide a short synopsis of marketplace transformation and liquid retail, from a socio-cultural perspective, and summarize the papers included in this special issue.     

Replacing executive stock options with share units: A Canadian study

Are share units a better compensation tool than stock options? This paper studies the impact of a transition within the compensation structures of CEOs of companies listed on the TSX Composite Index. Specifically, we ask whether replacing options with units-based compensation reduces the volatility of these companies' stock prices while promoting better returns. Our findings show that a shift to share units reduces large-cap Canadian companies' total risk through its idiosyncratic component. This transition is also accompanied by an increase in their risk-adjusted accounting and market performance. This suggests that share units are better for compensation contracts.
