Reparameterized inverse gamma regression models with varying precision

In this article, we propose a mean linear regression model where the response variable is inverse gamma distributed using a new parameterization of this distribution that is indexed by mean and precision parameters. The main advantage of our new parametrization is the straightforward interpretation of the regression coefficients in terms of the expectation of the positive response variable, as usual in the context of generalized linear models. The variance function of the proposed model has a quadratic form. The inverse gamma distribution is a member of the exponential family of distributions and has some distributions commonly used for parametric models in survival analysis as special cases. We compare the proposed model to several alternatives and illustrate its advantages and usefulness. With a generalized linear model approach that takes advantage of exponential family properties, we discuss model estimation (by maximum likelihood), black further inferential quantities and diagnostic tools. A Monte Carlo experiment is conducted to evaluate the performances of these estimators in finite samples with a discussion of the obtained results. A real application using minerals data set collected by Department of Mines of the University of Atacama, Chile, is considered to demonstrate the practical potential of the proposed model.     

The impact of oil price changes on Spanish and euro area consumer price inflation

This paper assesses the impact of oil price changes on Spanish and euro area consumer price inflation. We find that the inflationary effect of oil price changes in both economies is limited, even though crude oil price fluctuations are a major driver of inflation variability. The impact on Spanish inflation is found to be somewhat higher than in the euro area. In both economies, direct effects have increased in the last decade, reflecting the higher expenditure share of households on refined oil products, whereas indirect and second-round effects seem to be losing importance.     

Bank presence in firm equity: A diversification based approach

This study analyses the possible reasons for banks deciding to invest in firm equity, based on the fundamentals of the strategic diversification literature. Those fundamentals suggest that it may be in response to the negative evolution of other aspects of banking business, namely, credit business, fixed interest business and services, as well as the bank's level of efficiency. The results confirm the hypotheses that the decision to hold equity in other firms is related to the evolution of the bank's other businesses. However, the results for savings banks differed from those for banks.     

Sustainable Development and the Financial System: Society's Perceptions About Socially Responsible Investing

The debate surrounding the financial needs of investors and the impact on society of investment is considered to be an important research topic due to the growth of socially responsible financial markets. The main objective of this research is to study society's perception about socially responsible investing (SRI) and to identify investor's preferences regarding environmental, social and governance criteria, their real‐life investment needs and the most relevant sustainable financial products. To examine society's perception of SRI, we conducted a field survey among Spanish investors. The results show that SRI is at an early stage and Spanish investors need more exact information regarding social, environmental, and governance criteria in order to invest in socially responsible companies and products. This paper offers some guidelines that could be used by Spanish institutions, managers and investors and by foreign managers when approaching the Spanish market, in order to promote the growth of socially responsible financial products.

NYSE Euronext-Deutsche Börse merger: Let the dance go on!

While it has often been said that trading is like dancing, exchanges have certainly been dancing with one another for some time, following the need to diversify and cope with the results of a challenging liberalisation process. The proposed merger between NYSE Euronext and Deutsche Börse would create the world’s biggest exchange by revenues and total value. This needs the approval of 47 regulators across the globe, including the US Department of Justice and the European Commission. These institutions would be well advised not to try to stop the dance.     

Factors enhancing the choice of higher resource commitment entry modes in international new ventures

The choice of entry mode in foreign markets is an important strategic decision with major consequences for the success of international new ventures (INVs). It is generally accepted that these firms choose relatively low-resource commitment entry modes to operate in foreign markets. Nevertheless, some researchers have suggested that higher resource commitment entry modes in foreign markets also seem to be competitive strategies for INVs. In this study, from a marketing/international entrepreneurship interface perspective and focusing on organizational issues, we center our attention on international market orientation as a neglected yet important factor in INVs’ choice of higher resource commitment entry modes in foreign markets. We suggest that an entrepreneurial orientation and the timing of international entry are important correlates to an international market orientation. We also suggest that the international learning effort of INVs through their international market orientation has a direct, positive impact on the resources these companies commit to their foreign markets through the use of higher resource commitment entry modes. Accordingly, the model proposes a positive effect of entrepreneurial orientation and early international entry on international market orientation which, in turn, is positively related to higher resource commitment entry modes. The hypotheses were tested on country-level data from Spain, using a structural equation model to analyze relationships between the latent variables.This study extends previous international entrepreneurship research, including insights on antecedents of international new ventures’ choice of resource commitment entry modes in foreign markets. The paper also goes further than previous international entrepreneurship research, by addressing the strategic consequences of rapid entry into foreign markets. Additionally, the results of this work encourage international entrepreneurs to look beyond the explicit value of experiential market knowledge to realize the potential value of international market orientation as an antecedent to higher resource commitment entry modes.     

Response to ‘Duplications’ by Drelichman and Voth

In this response, we demonstrate that Mauricio Drelichman and Hans‐Joachim Voth, in their 2015 Economic History Review note ‘Duplication without constraints: Álvarez‐Nogal and Chamley's analysis of debt policy under Philip II’, provide a misconceived and inaccurate account of our argument about the finances of Philip II in ‘Debt policy under constraints: Philip II, the Cortes, and Genoese bankers’ (Economic History Review, 2014). Here, we summarize our position in the context of the current literature and provide a few comments on data gathering.
