SEBI index: Measuring the commitment to the principles of social banking

As a result of the financial crisis, ethical banking has become a visible phenomenon that has aroused the interest of those clients that are disappointed with conventional banking, as well as that of the scientific community. However, research on ethical banking has just started, with several subjects pending consensus, such as the proper definition or identification of banks considered to be ethical. In view of the above, the objective of this study is, first and foremost, to define the common characteristics of all banks affiliated to the movement; empirically, we shall quantify the level of commitment with the same and, thus, as a result of this quantification, obtain a ranking that classifies the selected banks according to the scores obtained. Regarding the methodology used, the quantification of the level of commitment with ethical banking is done through a new index called SEBI (Social and Ethical Banking Index), designed from the characteristics defined in the study and applied to the banks identified as ethical due to being a part of the main network of this type of banking: The Global Alliance for Banking on Values (GABV).     

Reducing the mean supply delay of spare parts using lateral transshipments policies

Lateral transshipment has been studied lately as a promising policy for increasing the performances of multi-echelon spare parts inventory system. By lateral transshipment spare parts can be moved from one location with excess inventory to another location, at the same echelon, in shortage, with the aim of reducing supply delays of spare parts. This paper will examine the relative effectiveness of two lateral shipments approaches in reducing the mean supply delay (MSD) of a non-repairable item, with respect to a classical policy of no lateral shipments. A simulation model of a two echelon supply network has been implemented and an experiment has been performed by varying different parameters of the supply network, such as the number of warehouses (locations at the lower echelon), the supply lead time from the central depot, the spare parts demand uncertainty, and the size variability of the warehouses. Results show appreciable reductions of MSD when lateral shipments are allowed with respect to the classical policy, in almost every network configuration.     

Valuation in Emerging Markets: A Simulation Approach

Most of the foundations of valuation theory have been designed for use in developed markets. Because of the greater, and in some cases different, risks associated with emerging markets (although recent experience might suggest otherwise), investors and corporate managers are often uncomfortable using traditional methods. The typical way of capturing emerging-market risks is to increase the discount rate in the standard valuation model. But, as the authors argue, such adjustments have the effect of undermining some of the basic assumptions of the CAPM-based discounted cash flow model. The standard theory of capital budgeting suggests that estimates of unconditional expected cash flows should be discounted at CAPM discount rates (or betas) that reflect only “systematic,” or “nondiversifiable,” market-wide risks. In practice, however, analysts tend to take what are really estimates of “conditional” expected cash flows—that is, conditional on the firm or its country avoiding a crisis—and discount them at higher rates that reflect not only systematic risks, but diversifiable risks that typically involve a higher probability of crisis-driven costs of default. But there is almost no basis in theory for the size of the increases in discount rates. In this article, the authors propose that analysts in emerging markets avoid this discount rate problem by using simulation techniques to capture emerging-market risks in their estimates of unconditional expected cash flows—in other words, estimates that directly incorporate the possibility of an emerging-market crisis and its consequences. Having produced such estimates, analysts can then discount them using the standard Global CAPM.     

The Spanish Labour Market: Reforms and consequences

The institutional design of the Spanish labour market has been subjected, during the last three decades, to permanent pressure fuelled by two beliefs. On the one hand, by the assumption that a higher degree of flexibility would help to reduce unemployment; on the other, by the assumption that such increased flexibility would also help to reduce inflation rates and, consequently, the inflation gap between Spain and the rest of the European countries. The recent history of the Spanish labour market is, therefore, the history of the reforms implemented to increase the flexibility in such a market. The aim of this paper is, firstly, to describe the main features of these reforms, showing the measures implemented in order to increase the flexibility in the labour market and, secondly, to show the degree of flexibility reached in the labour market. Finally, we will briefly analyse the macroeconomic consequences of these reforms.     

Should HR managers allow employees to use social media at work? Behavioral and motivational outcomes of employee blogging

Abstract

There is a dilemma for HR executives concerning social media policies: Should HR managers allow employees to use social media while at work? The question has no easy answer because there are conflicting views on the matter. However, the conflicting views can be resolved if we focus on the individuals with whom an employee interacts through social media. Building on data on the blogging activity of 269 employees working for a Canadian health-care provider, the paper reveals a new problem: The extent to which employees engage in personal blogging with outsiders – individuals who do not work for the organization – is negatively related to intrinsic work motivation and to proactive behavior. After having introduced the problem, the paper shows a solution. If employees engage in blogging with coworkers, the negative effects turn positive: Blogging with coworkers positively affects intrinsic work motivation and proactive behavior. Finally, the paper offers a recommendation for HR managers to leverage the solution. Through social job design and increasing formal interaction requirements, HR executives can reinforce the association between social media use and blogging with coworkers. Overall, the paper helps HR executives to clarify the outcomes of social media, find a problem, suggest a solution, and recommend how to achieve it.     

An application of padé approximation to volatility modeling

This paper studies the dynamic relationship between future volatility and implied and historical volatility using data from Alegría and Rodríguez [1997]. The methodological approach forms part of the theoretical research being carried out in numerical analysis and especially from the rational Padé approximation. This tool helps to characterize simple computational methods in order to study questions about dynamic modelization of doubly infinite series. Considering noncausal series, where the expectations provided by economic theory or empirical evidence are included in available sample data, leads to dynamic specifications suitable not only from the perspective of fitting available data, but also from their predictive performance when compared to traditionally used formulae based merely on data analysis.

Assessing Bond Market Developments Pot-Euro

As a result of global trends in the financial industry, European financial markets are in the midst of a major transformation, and Economic and Monetary Union (EMU) is acting as a primary catalyst for such change. Over time financial integration will provide European markets with sufficient liquidity and scale to turn them into effective rivals of the U.S. markets.
This paper provides a framework for assessing the likely consequences of EMU for the evolution of European bond markets. First, it discusses broad fundamental shifts in international capital flows and how EMU is expected to affect them. Second, it analyzes in some detail the two most important portfolio shifts expected to accompany Monetary Union: potential changes in currency reserves held by central banks and diversification of international investors' portfolios. Third, it considers the possibility that the asset management industry and households' increased appetite for risk will lead to a major shift on the demand side. On the supply side, it explores the likely effect of Monetary Union on government bond yield spreads and expected changes in the key pricing factors.
The paper concludes with an overview of the considerable growth prospects for the European corporate bond market. In the Euromarket, which has traditionally been the preserve of borrowers of high credit standing, there have already been signs of increased interest in corporate issues, particularly lower-rated ones. The search for higher yields by investors, greater expertise in analyzing credit risks by institutional investors, and reduced issuance in European government bond markets will combine to spur growth in the European corporate bond market. As a consequence, the traditional bank-oriented relations will clearly weaken, and more companies will find opportunities to raise capital and obtain financing at lower cost.     

The hidden problem of Facebook and social media at work: What if employees start searching for other jobs?

Companies are increasingly encouraging employees to use Facebook and other social media to interact with coworkers in order to empower collaboration and knowledge sharing. Yet, there is a hidden problem that has been neglected by managers. The more employees interact with coworkers through social media to facilitate their work in the organization, the more likely they are to learn about and become interested in other companies via social media, form new work connections outside the organization, and engage in job search behaviors. The use of social media to facilitate work and benefit organizations could paradoxically risk fostering withdrawal intentions and turnover, which damage organizations. This article provides evidence of this paradox from an empirical study. After having identified the problem, the article proposes both the solutions to avoid and the solutions to adopt, illustrating best practices from successful companies, comparing their benefits and costs, and indicating the situations in which each solution is best implemented. To conclude, I offer 10 recommendations to turn the problem into an opportunity and use social media as an innovative recruitment tool.     

A Social Contract Account for CSR as an Extended Model of Corporate Governance (II): Compliance,Reputation and Reciprocity

This essay seeks to give a contractarian foundation to the concept of Corporate Social Responsibility (CSR), meant as an extended model of corporate governance of the firm. Whereas, justificatory issues have been discussed in a related paper (Sacconi, L.: 2006b, this journal), in this essay I focus on the implementation of and compliance with this normative model. The theory of reputation games, with reference to the basic game of trust, is introduced in order to make sense of self-regulation as a way to implement the social contract on the multi-fiduciary model of corporate governance. This affords understanding of why self-regulation, meant as mere recourse to a long-run strategy in a repeated trust game, fails. Two basic problems for the functioning of the reputation mechanism are examined: the cognitive fragility problem, and the motivational problem. As regards the cognitive fragilities of reputation (which result from the impact of unforeseen contingencies and from bounded rationality), the paper develops the logic and the structure that self-regulatory norms must satisfy if they are to serve as gap-filling tools with which to remedy cognitive limitations in the reputation mechanism. The motivation problem then arises from the possibility of sophisticated abuse by the firm. Developed in this case is an entirely new application of the theory of conformism-and-reciprocity-based preferences, the result of which is that the stakeholders refuse to acquiesce to sophisticated abuse on the part of the firm. Lorenzo Sacconi is professor of economics and Unicredit Chair in economic ethics and corporate social responsibility at the Department of Economics of the University of Trento, where he leads the LaSER - Laboratory of research in Social responsibility, Ethics and Rationality, and head of the graduate program (laurea magistralis) in “economic decisions, enterprise and corporate social responsibility”. He is also director of EconomEtica, the interuniversity centre for economic ethics and corporate social responsibility joining over 20 Italian Universities placed at the Milano-Bicocca University. Past president of tthe Italian Business Ethics Network and past member of the EBEN executive committtee, currrently he is a member of the executive committee of the Italian chapter of EBEN (EBEN Italy).
