Consumer Ethics in the European Union: A Comparison of Northern and Southern Views

There is a growing interest in understanding consumer ethical actions in relation to their dealings with firms. This paper examines whether there are differences between Northern and Southern European Union (EU) consumers' perceptions of ethical consumer behaviour using Muncy and Vitell's (1992) Consumer Ethics Scale (CES). The study samples 962 university students across four Northern EU countries (Germany, Denmark, Scotland, The Netherlands) and four Southern EU countries (Portugal, Spain, Italy, Greece). Some differences are identified between the two samples, which might question the ability of organisations to consider the EU as one homogeneous market.     

Backward integration and collusion in a duopoly model with asymmetric costs

This paper formalizes the idea that input transactions might be used to implement side payments among colluding firms. A model is proposed to analyze the effect of backward integration on collusive outcomes in a downstream duopoly with asymmetric marginal costs. Vertical integration expands the set of collusive outcomes that are sustainable for a given realization of the discount factor. This is an additional effect of vertical integration that antitrust authorities should consider. Side payments implemented by input sales are more relevant the larger the difference in marginal costs, since they allow for the shifting of production towards the relatively more efficient firms, while maintaining firms’ incentives to collude. A price of the input above that posted by an alternative source or sales of the input below cost may be observed, depending on the realization of downstream firms’ costs.      

Equilibrium play and best response to (stated) beliefs in normal form games

We report experimental results on a series of ten one-shot two-person 3×3 normal form games with unique equilibrium in pure strategies played by non-economists. In contrast to previous experiments in which game theory predictions fail dramatically, a majority of actions taken coincided with the equilibrium prediction (70.2%) and were best-responses to subjects' stated beliefs (67.2%). In constant-sum games, 78% of actions taken were predicted by the equilibrium model, outperforming simple K-level reasoning models. We discuss how non-trivial game characteristics related to risk aversion, efficiency concerns and social preferences may affect the predictive value of different models in simple normal form games.     

The Evolution of Industrial Earnings Inequality in Mexico and Brazil

Industrial data are used to derive estimates of the pattern of change in wage inequality in Mexico and Brazil. Using the group decomposition of Theil's T -statistic, the paper presents monthly changes in the dispersion of industrial wages for Brazil (1976 through 1995) and for Mexico (1968 through 1998). Both countries show increases in wage dispersion over time, and a strong negative correlation is found with the rate of real economic growth. Other things equal, the later Brazilian heterodox stabilization plans seem to have reduced inequality in the short run.     

Raising the bar (7)

This editorial summarises the papers published in issue 13.1 so as to raise the bar in applied spatial economic research and highlight new trends. The first paper adopts a scale neutral approach to investigate the spatial mechanisms that cause regional innovation and growth. The second paper claims that population-weighting when calculating indices of regional inequality might lead to inconsistent outcomes. The third paper estimates the effect of distance between family residence and higher education institution on a student's academic performance, thereby accounting for endogenous regressors. The fourth paper shows an inverted U-shaped relationship between economic development at region of origin and the propensity to migrate using a multilevel approach. The fifth paper provides spatial econometric evidence of price competition between sellers of used books on Amazon.com. The last paper estimates a hedonic housing price equation and parameterizes the spatial weight matrix to determine how far back in time buyers, sellers and realtors are looking at the housing market.     

Reducing intentions to resist future change: Combined effects of commitment‐based HR practices and ethical leadership

Change management, and particularly the human side of change, is a central tenet of the strategy of contemporary organizations. However, there is little evidence concerning how strategic HR practices influence how individuals anticipate and react to the implementation of a major change and how direct supervisors influence that process. With a sample of 191 employees from multiple organizations, who completed two surveys with a four‐week lag, we examined the role of commitment‐based HR practices on employees’ intentions to resist future change. We found that commitment‐based HR practices contribute to a decrease in intentions to resist future change, measured four weeks later, via increased affective commitment to change. Moreover, we found that this relationship is conditional on ethical leadership, in that it is significant when ethical leadership is high but not when it is low. Building on social exchange and uncertainty reduction theories, our findings contribute to the literature by examining how and under what boundary conditions HR practices are an effective means for organizations to anticipate and manage change.

Raising the bar (11)

This editorial summarizes the papers published in issue 14(2) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper deals with past and current challenges for regional science research. The second paper investigates whether people living in deprived neighbourhoods have less chance of succeeding in a job application. The third paper finds evidence that real estate firms can avoid price competition when market shares of their allies increase in the vicinity. The fourth paper is methodological: it considers a spatial autoregressive (SAR) model with heterogeneous coefficients and extensively analyzes the impact of this extension on the direct and indirect effects estimates. The fifth paper proposes an innovative method to estimate the elements of the spatial weight matrix in a spatial econometric model. The final paper is econometric–theoretical: it proposes a new generalized method of moments (GMM) estimator of the coefficients of a SAR model if the error terms are heteroskedastic of an unknown form.
