The Risk-Return Relationship of Pension Funds With Investments in Hedge Funds

This article investigates if investing in local hedge funds improves the risk-return relationship of Brazilian pension funds. Investment in hedge funds by pension funds is growing elsewhere, with an increasing utilization of a multiplicity of hedge funds specialized in specific strategies or niches. We analyzed the performance of a typical pension fund allocation in Brazil as well as alternate allocations that included hedge funds. We used robust estimates of the covariance matrix to mitigate the errors in variables that are problematic in the inputs of the optimization. The results show that hedge funds improve the risk-return relationship of the typical pension fund allocation, contribute to a higher accumulated return at the end of a one-year period, and reduce portfolio rebalancing. Investments in hedge funds ease reaching the typical 6% annual return target with less risk exposure.     

Comprehensive indicators of traffic-related premature mortality

Motor vehicle circulation is associated with multiple social benefits; nevertheless, it is widely acknowledged that it also produces a variety of adverse health effects, of which the most relevant are associated with mortality from road accidents and exposure to atmospheric pollution. Though in Chile these impacts have been quantified and evaluated independently, no indicators have been developed so far to account for this activity’s global impact on public health, or to express the individual impact that can be attributed to each vehicle category. In order to fill this void, the present study aimed at designing and quantifying indicators that account for the global impact on health that different motor vehicle categories impose on Chilean society. Health impact was quantified as the number of expected premature deaths caused by road accidents and exposure to atmospheric pollutants. Total premature mortality was understood as the total annual deaths that occurred as a consequence of road accidents and the exposure to O₃ and PM_2.5 derived from traffic-related emissions of its precursors. All estimations were made considering Chile’s Metropolitan Region in 2005 as a basic scenario. Differentiated indicators were obtained for 15 vehicle categories as a function of different parameters: traveled kilometer, vehicle, and vehicle lifetime. According to our results, when the health impact of traffic accidents and exposure to traffic-related air pollution are considered simultaneously, major differences were observed with the indicators traditionally used by regulators involved in the traffic-related decision-making process. The implications of our results on risk management strategies are discussed.     

Measuring the antecedents of e-loyalty and the effect of switching costs on website

This paper deals with the process by which electronic customer loyalty (e-loyalty) is formed. The twofold aim is to analyse e-loyalty, describing its development in terms of how it is influenced by several determinants and to study potential barriers to switching which significantly affect the repeat purchase decision. In particular, an integrating theoretical framework is proposed to determine the e-loyalty dependency of electronic service quality and perceived value, and how this last relationship can be moderated by switching costs. Results offer evidence for the important role of customer's perceptions of e-service quality and value in e-loyalty. Proposals are made of how companies that are online can use this knowledge to build marketing strategies.     

Aligning supply chain design for boosting resilience

Many researchers have analyzed the effect of disruptive events, such as natural disasters and economic and market forces, on global supply chains. However, there is a lack of consensus on delineating a universal collection of supply chain risk management practices that will help companies operate in a global market with large-scale disruptions. In this article, we present an analysis, in conjunction with a worldwide online survey, based on successful global brands and their supply chains. We propose a framework that deploys the dynamics of building supply chain resilience, first linking the design of the supply chain portfolio (local versus global scope, as well as strategic responsiveness versus cost reduction) with supply chain vulnerabilities (external versus internal). We describe the transition between different supply chain structures as a way of coping with disruptions and thus proactively developing resilience. In this article, we introduce both a supply chain risk management approach and the reactive-by-deployment mode, as illustrated by successful global company examples.     

The effect of knowledge complexity on the performance of franchise systems in the service industries: an empirical study

The literature of knowledge transfer studies complexity as a knowledge characteristic which influences organisations’ performance since it hinders this process. However, complex knowledge is richer and more complete and its influence on performance may be positive. So, the purpose of this study is to analyse the influence of knowledge complexity on the performance of franchise systems in the service industries. With this aim, a linear regression analysis is conducted on a sample of franchisee of different franchise chains of the several service industries operating in Spain. The findings seem to indicate that complexity has a positive impact on the performance of franchise systems.     

Microfinance Beyond Group Lending

Microlending is growing in Eastern Europe, Russia and China as a flexible means of widening access to financial services, both to help alleviate poverty and to encourage private-sector activity. We describe mechanisms that allow these programmes to successfully penetrate new segments of credit markets. These features include direct monitoring, regular repayment schedules, and the use of non-refinancing threats. These mechanisms allow the programmes to generate high repayment rates from low-income borrowers without requiring collateral and without using group lending contracts that feature joint liability.     

Pair-copulas modeling in finance

This paper concerns itself with applications of pair-copulas in finance, and bridges the gap between theory and application. We provide a broad view of the problem of modeling multivariate financial log-returns using pair-copulas, gathering together for this purpose theoretical and computational results from the literature on canonical vines. From the practitioner’s viewpoint, the paper shows the advantages of modeling through pair-copulas and makes clear that it is possible to implement this methodology on a daily basis. All the necessary steps (model selection, estimation, validation, simulations, and applications) are discussed at a level easily understood by all data analysts.     

Sources of Comparative Advantages in Brazil

Based on the Heckscher-Ohlin-Vanek model, the authors investigate relative factor abundance in Brazil, as revealed by its international trade. They study two different time periods: one characterized by high trade barriers (1980–85) and the trade liberalization period (1990–95). Two alternative methodologies are used: the estimation of factor intensity regressions on net exports and the direct computation of factor content in net exports. In the factor intensity regression, the authors incorporate technological changes that might have occurred over time, and these turn out to be significant. Both methods yield the same results: the Brazilian international trade reveals relative abundance in capital, land, and unskilled labor, and scarcity in skilled labor, with qualitatively equivalent results for the two time periods studied.     

Land Cover in a Managed Forest Ecosystem: Mexican Shade Coffee

Managed forest ecosystems like shade coffee supply valuable ecological services. Yet little is known about the drivers and characteristics of clearing in such systems. We present a spatial econometric analysis of land cover in a shade coffee region in southern Mexico. We find that plots close to large cities are less likely to be cleared all other things being equal—the opposite of the pattern usually observed in natural forests. In addition, we find that membership in coffee-marketing cooperatives, farm size, and certain soil types are associated with tree cover, while proximity to small town centers is associated with clearing.
