Mean-variance cointegration and the expectations hypothesis

The present paper sheds further light on a well-known (alleged) violation of the expectations hypothesis of the term structure (EHT): the frequent finding of unit roots in interest rate spreads. We show that the EHT implies (i) that the nonstationarity stems from the holding premium, which is hence (ii) cointegrated with the spread. In a stochastic discount factor framework, we model the premium as being driven by the integrated variance of excess returns. Introducing the concept of mean-variance cointegration, we actually find cointegration relations between the conditional first and second moment of US bond data.     

Collective versus Random Fining: An Experimental Study on Controlling Ambient Pollution

This paper presents an experimental study oftwo different pollution compliance games:collective vis-à-vis random fining as ameans to regulate non-pointpollution. Using samples from both Costa Ricancoffee mill managers and Costa Rican students,we find that the two games perform equivalentlybut, although they lead to efficient outcomesthrough Nash play in the majority of cases, theobserved frequency of Nash play is lower thantheoretically predicted. Moreover, we rejectthe hypothesis that managers and studentsbehave equally. Off the equilibrium, managerstend to over-abate, whereas students tend tounder-abate. This result suggests theimportance of considering subject pooldifferences in the evaluation of environmentalpolicies by means of experiments, particularlyif those policies involve certain forms ofmanagement decisions.     

Conflicting Claims and Equilibrium Adjustment Processes in a Stock-flow Consistent Macroeconomic Model

We revisit the old but still vibrant Post-Keynesian debate over ‘fully-adjusted positions’, defined by the long-run equality of actual and standard utilisation rates. The central proposition of this paper is that in a world where different groups inside and outside firms have different objectives, the equality of actual and standard utilisation should not be treated as the only possible long-run equilibrium condition. The argument is illustrated in a model of target return pricing with conflict inflation, building on the work of Marc Lavoie. A ‘common language’ for the conflicting claims by shareholders, managers and workers is developed in terms of target profit rates, and it is shown that these contradictory claims can be partly reconciled through variations in the utilisation rate. The analysis unifies history and equilibrium in the sense that the nature of final equilibrium position and the adjustment to it depend on the objectives of the dominant social groups. We distinguish a ‘Fordist regime’ and a ‘financialisation regime’ and produce simulation results within a simple stock-flow consistent model that are broadly consistent with the stylised facts of these distinct historical phases of capitalism.     

The role of contingency awareness,involvement, and need for cognition in attitude formation

This research investigates the role of involvement and need for cognition in influencing contingency awareness in attitude formation. Two experiments examine the nature of favorable attitudes formulated through established classical conditioning procedures. The results of Experiment 1 indicate that awareness influences attitudes toward a conditioned stimulus, particularly under conditions of high involvement and high need for cognition. Experiment 2 suggests that contingency awareness mediates the relationship between inferential belief formation and attitudes and that this effect is stronger under high involvement and high need for cognition. Implications for understanding the role of classical conditioning procedures in advertising are discussed.

Brand alliance and customer‐based brand‐equity effects

This research examines brand alliances, a specific marketing strategy designed to transfer the positive brand equity of two or more partner brands to the newly created joint brand. The study explores how customer‐based brand equity (that is, brand equity as seen from the customer's perspective) of partner brands affects consumer evaluations of an alliance brand; how the brand equity of one partner brand affects the other; how customer‐based brand equity of the partner brands affects consumers' evaluations of the search, experience, and credence attribute performance of the alliance brand; and how product trial influences such evaluations. Results suggest that merely the act of pairing with another brand elevates consumers' evaluations of the partner brands' customer‐based brand equity, and high‐equity partners enhance pretrial evaluation of experience and credence attributes that are relevant to the high‐equity partner. As hypothesized, product trial moderates the equity value of the alliance partner for experience attributes, and brand equity of the partner brands influences consumer perceptions of the alliance brand's equity. © 2004 Wiley Periodicals, Inc.     

Inference by linearization for Zenga’s new inequality index: a comparison with the Gini index

Zenga’s new inequality curve and index are two recent tools for measuring inequality. Proposed in 2007, they should thus not be mistaken for anterior measures suggested by the same author. This paper focuses on the new measures only, which are hereafter referred to simply as the Zenga curve and Zenga index. The Zenga curve Z(α) involves the ratio of the mean income of the 100α % poorest to that of the 100(1?α)% richest. The Zenga index can also be expressed by means of the Lorenz Curve and some of its properties make it an interesting alternative to the Gini index. Like most other inequality measures, inference on the Zenga index is not straightforward. Some research on its properties and on estimation has already been conducted but inference in the sampling framework is still needed. In this paper, we propose an estimator and variance estimator for the Zenga index when estimated from a complex sampling design. The proposed variance estimator is based on linearization techniques and more specifically on the direct approach presented by Demnati and Rao. The quality of the resulting estimators are evaluated in Monte Carlo simulation studies on real sets of income data. Finally, the advantages of the Zenga index relative to the Gini index are discussed.
