Characterising human resources management practices in Portugal: an empirical analysis

The importance of human resources as a fundamental channel towards the competitiveness and sustainability of firms is now theoretically unchallenged. This article provides an overall characterisation of the main human resources management (HRM) practices implemented in Portugal and compares them with the benchmark models proposed in the literature.

To evaluate the degree to which HRM practices diverge from these benchmark models, this article relies on the analysis of five criteria: i) How do the main HRM practices fit the existing management models (familiar, professional or mixed); ii) How does the HRM conform to a work organisation of the matricial type; iii) To identify whether the role of HRM is essentially administrative or strategic; iv) To identify where the responsibility for HRM lies within the firms operating in Portugal; and v) To characterise the relation between HRM and work organisation in Portugal.

Drawing on a representative sample of firms operating in Portugal, we identify three clusters that allow us to characterise and analyse the stylised HRM practices implemented in Portugal (network-based, familiar-based or bureaucratised). Results show contrasting management patterns, which can be interpreted as different stages of evolution in terms of HRM practices in Portugal.     

A new approach to bad news effects on volatility: the multiple-sign-volume sensitive regime EGARCH model (MSV-EGARCH)

In this paper, using daily data for six major international stock market indexes and a modified EGARCH specification, the links between stock market returns, volatility and trading volume are investigated in a new nonlinear conditional variance framework with multiple regimes and volume effects. Volatility forecast comparisons, using the Harvey-Newbold test for multiple forecasts encompassing, seem to demonstrate that the MSV-EGARCH complex threshold structure is able to correctly fit GARCH-type dynamics of the series under study and dominates competing standard asymmetric models in several of the considered stock indexes.

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.     

Cross-cultural factors in international branding

Abstract

This is the second special issue resulting from the symposium titled ‘The Brand and Its History’. This issue aims at deepening the knowledge of the historical and cultural roots of the origin, uses, and meanings of modern branding. This editorial summarises previous contributions from economic, marketing, and historical literature; presents the main findings of the seven articles included in this issue; and reflects on possible further research.     

Government ideology and economic freedom

This paper tests the widespread belief that right-wing governments tend to promote economic freedom while left-wing ones prefer more control over the economy. Using annual data for 106 countries over the period 1975-2015 and a two-step system GMM estimator, this study shows that right-wing governments are indeed more prone to promote economic freedom and to deregulate the economy. It also finds that this effect seems to be stronger in developing/emerging economies than in more developed countries. Moreover, the analysis of the broad dimensions of economic freedom indicates that right-wing governments tend to act by improving monetary soundness and freedom to trade internationally and by easing regulations that restrict entry into markets. Mainstream left-wing governments do not seem to affect economic freedom, however populist left-wing parties, when in office, are found to have a detrimental effect.
