An application of padé approximation to volatility modeling

This paper studies the dynamic relationship between future volatility and implied and historical volatility using data from Alegría and Rodríguez [1997]. The methodological approach forms part of the theoretical research being carried out in numerical analysis and especially from the rational Padé approximation. This tool helps to characterize simple computational methods in order to study questions about dynamic modelization of doubly infinite series. Considering noncausal series, where the expectations provided by economic theory or empirical evidence are included in available sample data, leads to dynamic specifications suitable not only from the perspective of fitting available data, but also from their predictive performance when compared to traditionally used formulae based merely on data analysis.     

Input cost, capacity utilization and substitution in the short run

This article studies the behavior of input cost shares in an environment where labor is costly to adjust, materials can be adjusted at no cost and capital is fixed. A model relating cost shares with relative prices and adjustment costs is proposed, allowing joint estimation of the elasticity of substitution and the adjustment cost function, which is an unknown function of the capacity utilization. Based on a panel of more than 700 manufacturing firms, we find evidence of strong input share variations according to the degree of capacity utilization. The estimated shapes of adjustment costs curves of labor are in agreement with our theoretical model, and we obtain sensible elasticities of substitution estimates. Based on such estimates, we find evidence of a negative (positive) bias in downturns (recoveries) in conventional productivity growth measures.     

Bank Disclosure and Market Assessment of Financial Fragility: Evidence from Turkish Banks’ Equity Prices

In this paper we explore whether Turkish banks with worsening indicators of financial fragility were subject to market monitoring during the years leading to the 2000/2001 crisis, and how the quality and timeliness of the disclosure affect market reaction. We find that shareholders reacted negatively to indicators of financial fragility such as increases in maturity mismatches, currency mismatches, and non-performing loans, showing shareholders’ concerns about the impact of financial fragility indicators on future profits. We also find that audited statements that show larger reporting lags, are not informative, pointing to the need of improving their timeliness. Finally, our study suggests that the finding that securities prices react to financial fragility indicators should not be taken as sufficient evidence of banks’ safety and soundness.     

Ownership structure and debt maturity: new evidence from Spain

Companies can use supplier financing as a source of short-term finance. The main objective of this paper is to extend the literature on the determinants of accounts payable and to test whether the accounts payable follow a model of partial adjustment. To do this, we use a sample of 3,589 small and medium sized firms in the UK. Using a dynamic panel data model and employing GMM method of estimation we control for unobservable heterogeneity and for potential endogeneity problems. The results reveal that firms have a target level of accounts payable. In addition, we find that larger firms, with better access to alternative internal and external financing and with a lower cost, use less credit from suppliers. Moreover, firms with higher growth opportunities use more trade credit for financing sales growth.     

Including vulnerable groups in financial services: insights from consumer satisfaction

The crisis brought into relief problems within the financial sector which seriously affected consumer trust. This paper provides new evidence on the experiences of two socio-economic groups associated with potential vulnerability – the less educated and the elderly – with financial service markets across Europe. We find that the less educated and the elderly are less satisfied and experience greater difficulties than other consumers as regards complaining, comparing offers, or switching, in the mortgage, and investment product and bank account markets, respectively. This evidence is of use to policy-makers seeking ways of improving financial regulation from a consumer perspective.     

Corporate social responsibility perception in business students as future managers: a multifactorial analysis

This paper examines undergraduate business students' perception of corporate social responsibility (CSR) in cases in which they have not attended any specific course either dealing with CSR or providing training in ethics. A survey was conducted of 535 Spanish business students as future managers. The results show that the stakeholders' perspective deserves a huge attention for those students considering what the keys of business success are. Significant differences in perception were nevertheless identified when a multifactorial analysis was undertaken. Female students are more concerned about CSR issues. The maximization of value for shareholders is less valued by second‐ and third‐year students than by first‐year ones. The findings point to a number of important orientations for the future development of university curriculum.     

Does having women managers lead to increased gender equality practices in corporate social responsibility?

There is increasing interest in determining what impact having women in management positions may have on corporate social responsibility (CSR) initiatives. Various authors suggest that gender equality practices should be factored into the broader framework of CSR. This paper examines how the presence of women on corporate boards, in top and middle management and as heads of CSR departments, influences gender equality practices in the field of CSR. Using information collected from companies that have signed up to Women's Empowerment Principles in Spain, we show that the presence of women in the aforesaid posts has a positive impact on CSR activities with gender equality objectives. We thus supplement the justice, business and moral arguments with further arguments in support of the incorporation of women into not only corporate boards but all management positions. Finally, we provide a view of how gender equality can be included in the broader framework of CSR.
