A Geometrical Interpretation of Collinearity: A Natural Way to Justify Ridge Regression and Its Anomalies

Justifying ridge regression from a geometrical perspective is one of the main contributions of this paper. To the best of our knowledge, this question has not been treated previously. This paper shows that ridge regression is a particular case of raising procedures that provide greater flexibility by transforming the matrix X associated with the model. Thus, raising procedures, based on a geometrical idea of the vectorial space associated with the columns of matrix X , lead naturally to ridge regression and justify the presence of the well-known constant k on the main diagonal of matrix X ^′ X . This paper also analyses and compares different alternatives to raising with respect to collinearity mitigation. The results are illustrated with an empirical application.     

Trading activities,productivity and markups: Evidence for Spanish manufacturing

This work analyses the firms' internationalisation strategies of importing intermediates and exporting output, and the potential rewards of these activities in terms of total factor productivity (TFP), as a proxy for marginal costs, and markups. It further deepens into the study of the relationship between internationalisation strategies and markups by disentangling whether it operates through affecting firms' marginal costs and/or firms' prices. The panel database employed in this paper is the Spanish Survey on Business Strategies (ESEE) for the period 2006–14. Results in the paper distinguish between SMEs and large firms and indicate that there is high persistence in the performance of these activities and in firms' TFP and markups. For SMEs, we obtain rewards from importing inputs as well as exporting output in terms of TFP and markups. For large firms, we obtain rewards in TFP from the importing activity and rewards in markups from the exporting activity. Finally, we find evidence that the effects of internationalisation strategies on markups are due to both a price channel and a marginal cost channel.     

Marketing capabilities and innovation. How do they affect the financial results of hotels?

From the point of view of firms’ managers, the knowledge of the factors which explain their firms’ financial results is considered of great usefulness to propose the most appropriate and profitable marketing strategies and actions. This research sets out from this central idea and proposes a model of relationships that considers the marketing results, the marketing capabilities, and the innovation capability as key factors for achieving good financial results. This model is verified via an empirical investigation carried out among 200 directors of hotel establishments in Andalusia, a region in the south of Spain which is one of the country's main tourist destinations. The results indicate that innovation capability is strongly conditioned by marketing capabilities and resources and that this innovation capability affects the financial results of the firms analyzed. Likewise, it is deduced that a market-oriented management philosophy contributes to the development of these marketing capabilities. The implications for management are considered very relevant as they must lead these firms to invest in the development of marketing resources and capabilities, and apply a market-oriented management philosophy if they wish to improve their financial results.     

Upgrading peripheral wind sectors

The implementation of traditional policies does not consider institutional singularities in peripheral sectors. The main aim of this paper is to analyse the interaction among local capabilities and multinational agents to upgrade a peripheral wind sector. The case study conducted in the peripheral region of Galicia (Spain) emphasises the challenges concerning policy design and implementation in this kind of regions. The theoretical foundations are based on the systemic and evolutionary approach of the innovation system and the global value chain perspective. This combination enables to analyse how local contexts could shape governance patterns within value chains in peripheral regions. Likewise, the target approach is also applied concerning the design and implementation of a policy programme and its timing. Empirical evidences underline the complementarity of market size and foreign direct investment policies, as well as the diversification towards green transitions through enhancing local capabilities.     

Exploring the customer's intention to switch firms: The role of customer‐related antecedents

This study examined the customer‐related antecedents of the customer's intention to switch firms. Customer citizenship behavior was a key element in this study. Scholars have extensively studied the antecedents of customer citizenship behavior. However, the way that customer citizenship behavior relates to other attitudinal variables and the intention to switch has scarcely been analyzed. The proposed hypotheses were verified using partial least squares variance‐based structural equation modeling applied to 947 users of beauty care service firms in five countries. The results suggest that customer citizenship behavior is an antecedent of satisfaction, trust, and attitudinal loyalty. Two of these variables influence customers’ intentions to abandon relationships with the service provider. The implications of these findings enhance managers’ and scholars’ understanding of the determinants of customers’ intentions to switch firms.     

Determinants of corporate social responsibility and business ethics education in Spanish universities

The current economic crisis, unsustainable growth, and financial scandals invite reflection on the role of universities in professional training, particularly those who have to manage businesses. This study analyzes the main factors that might determine the extent to which Spanish organizational management educators use corporate social responsibility (CSR) or business ethics stand‐alone subjects to equip students with alternative views on business. A web content analysis and non‐parametric mean comparison statistics of the curricula of undergraduate degrees in all universities in Spain were conducted. The main conclusion of this paper is related to the Bologna effect in Spanish universities. Comparing our results with prior research in this matter, it is demonstrated that the main reason that explains the increase of CSR and ethical education in Spain is the Bologna process and its adaptation to the European Higher Education Area. Also, private universities in Spain are more likely to require an ethics course than public universities. Other factors, such as size, political orientation, or related to CSR chairs are not statistically explanatory of CSR and ethical education.     

El desempeño económico financiero y responsabilidad social corporativa Petrobrás versus Repsol

Alterations in the institutional environment, as a result of the markets integration process and the consequent alterations in stakeholders’ conduct are one of the important vectors of changes in companies’ behavior. In that context, in addition to their yields those companies happen to worry about their attitudes in relation to social and environmental factors. Thus, the corporate social responsibility (CSR) is seen as one more strategy to maintain or increase their income and to harness the enterprise development. The main purpose of this study is the verification of the existing relation between Social Responsibility and the economic and financial performance of two companies in the business of Petroleum, Gas and Bio-combustibles. The investigation was based on a comparison of social-environmental practices developed by Petrobras S/A (Brazil) and Repsol S/A (Spain). For the purpose of verification of the relation between social-environmental performance and the economic-financial one, a linear regression analysis was carried out.     

Do online discounts and free gifts damage brand image of service? The moderating role of promotion-proneness

The present paper outlines a study based on an experimental design that investigated the effect of online price discounts and free gifts on consumers’ evaluation of the brand, in the context of an airline. The study also analyzed whether promotion-proneness exercises a moderating effect on this relationship. It was found that discounts generate a more positive brand image than free gifts among promotion-prone users, while for less promotion-prone individuals, the opposite is true. The results will help managers to select the most appropriate online sales promotion type for reaching different consumer groups, depending on their promotion-proneness, in line with the needs and objectives of the service firm.     

ACQUISITION OF INFORMATION TO DIVERSIFY CONTRACTUAL RISK*

Are hedging transactions that diversify a manager’s compensation risk detrimental to incentives, or can they improve contracting efficiency? If hedging provides efficiency benefits, should the manager or the firm undertake it? In our model, both the firm and the manager can trade financial portfolios to diversify the manager’s compensation risk. Prior to the portfolio selection, the parties need to acquire information on how different financial portfolios fit their diversification purposes. We illustrate that financial portfolios correlated with firm‐specific risk improve contracting efficiency. For equal information costs, it is optimal for the firm to undertake the hedging on the manager’s behalf.
