The Irresistible Fetish of Utility Theory: From “Pleasure and Pain” to Rationalising Torture

This note briefly examines the path that the economics discipline has taken since adopting the assumption that human behaviour is exclusively driven by utility maximisation. This view has prevented the full comprehension of most economic phenomena and has spread to other social disciplines, occasionally leading to results either ridiculous or tragic, such as using utility theory to rationalise torture. Such academic absurdity must be ended.     

The Ethics of the Living Wage: A Review and Research Agenda

To date, business ethicists, corporate social responsibility scholars as well as management theorists have been slow to provide a comprehensive and critical scrutiny of the Living Wage concept. The aim of this article, therefore, is to conceptualize the living wage (LW) in its philosophical as well as practical dimensions in order to open up the ethical implications of its introduction and implementation by companies. We set out the legal, socio-institutional and economic contexts for the debates around the LW and review arguments for, and against, it. Key philosophical arguments from the perspectives of sustainability, capability and externality are invoked and discussed in order to demonstrate the issues and challenges involved for companies, state and civil society actors. Relevant examples from the private sector are examined to demonstrate some of the practical issues involved when the LW is introduced by employers. The article also recommends avenues for a research agenda into the LW for business ethicists, CSR and management researchers in contexts such as the UK, where a voluntary, rather than mandatory, approach to the implementation of the LW is adopted.     

Corporate Networks and Business Groups in Argentina in the Early 1970s

This article examines the interlocking directorates' structure of prominent Argentine business groups at the end of the import substitution period (1970–72), identifying corporate relations among and between business groups and the largest companies, during a period characterised by high institutional and macroeconomic instability. Applying social network analysis, it seeks to clarify how business groups can contribute to the cohesion of a corporate network structure, through their ability to create links among firms not only within their boundaries but also external to them. The article contributes to both corporate network and business groups' literature, highlighting a role of business groups that extant literature has failed to identify as relevant.     

An Empirical and Theoretical Exploration of Disconnections Between Leadership and Ethics

A comparison of two groups of college students, at a public state university and a private religious school, yields the same results: undergraduates’ interpretations of recent business scandals make distinctions between public and private behavior. Students admire “family men” even when they are caught at fraud. The students’ interpretations illustrate a significant gap in ethical theories: the benefits of a group perspective for corporate citizenship versus individual family values. Most leadership theories, including stakeholder theories, do not address this disjunction. This article describes the phenomenon and maps the ethics literature to locate the dynamic forces underlying the empirical and theoretical disconnections between leadership and ethics.     

THE TERM PREMIA RELATIONSHIP IMPLICIT IN THE TERM STRUCTURE OF TREASURY BILLS

This paper considers a single coefficient representation of the term premia relationship that appears in treasury bill yield curves. Term premia are defined as positive or negative maturity-dependent differentials versus the instantaneous nominal spot rate. The term premia function is developed in the context of the Cox, Ingersoll, and Ross [ 3 ] Risk-Averse Preferred Habitat Model and proxies for the degree of risk aversion exhibited by the universe of treasury bill investors at a point in time. Empirical results indicate that term premia are influenced by a set of macroeconomic variables in the expected manner.     

Default Recovery Rates in Credit Risk Modelling: A Review of the Literature and Empirical Evidence

Evidence from many countries in recent years suggests that collateral values and recovery rates (RRs) on corporate defaults can be volatile and, moreover, that they tend to go down just when the number of defaults goes up in economic downturns. This link between RRs and default rates has traditionally been neglected by credit risk models, as most of them focused on default risk and adopted static loss assumptions, treating the RR either as a constant parameter or as a stochastic variable independent from the probability of default (PD). This traditional focus on default analysis has been partly reversed by the recent significant increase in the number of studies dedicated to the subject of recovery‐rate estimation and the relationship between default and RRs. This paper presents a detailed review of the way credit risk models, developed during the last 30 years, treat the RR and, more specifically, its relationship with the PD of an obligor. Recent empirical evidence concerning this issue is also presented and discussed.

IN SEARCH OF A STYLISED FACT: DO REAL WAGES EXHIBIT A CONSISTENT PATTERN OF CYCLICAL VARIABILITY?

Abstract. The paper surveys the studies on the cyclical behaviour of real wages published from the twenties onwards. Both traditional simple neoclassical and keynesian models of the labour market suggest that real wages tend to move countercyclically. However, from a theoretical viewpoint, there are few reasons to expect this behaviour, once the simple model is extended to account for imperfect competition, uncertainty, lagged responses, or contracting between firms and workers. Empirical studies give different answers to the problem. The contributions reviewed in the paper are arranged roughly in chronological order: the interwar period, the postwar pre-econometric studies, the econometric work using aggregate data, the evidence produced on the basis of longitudinal data, the analyses of the shock-responsiveness of real wages, and, finally, the most recent papers attempting a reconciliation of the somewhat conflicting evidence derived from aggregate and panel data.
