Corporate brand image in retail banking: development and validation of a scale

Recent changes in deregulation and technology have made banking one of the most competitive sectors in the global economy. Within this background, corporate image management has gained importance as a way of differentiating companies. This paper aims to develop a scale to analyse the corporate image in banking. Derived from a review of the literature, a scale with the most cited dimensions of analysis is developed. This scale is then tested by means of an empirical study of 450 individuals, where dimensionality, reliability and validity requirements are confirmed. Both theoretical and managerial implications are presented.     

The impact of process innovations on firm's productivity growth: the case of Spain

The main aim of this paper is to investigate about the effect that a measure of the process innovation performance of a firm has on its labour productivity growth. This analysis is mainly a consequence of two considerations. The first one results from a clear differentiation of the role that product and process innovations have on a firm's performance. The second one is to assume that the knowledge capital of a firm is mainly composed by its successful research. The study demonstrates that process innovation has a positive and significant effect on firm's productivity growth. Moreover, this result is robust under a wide range of alternative specifications and, in any case, the variable behaves much better than R&D intensity. Following previous research, the detected quadratic relationship between vertical product differentiation and process innovation performance leads to the existence of some firms for which there exist a trade–off between quality and productivity.     

GARCH inadequacy for modelling exchange rates: empirical evidence from Latin America

This article checks for the adequacy of using GARCH models in exchange rate series. Using the Hinich portmanteau bicorrelation test, we find that a GARCH formulation or any of its variants fails to capture the data generating process of the main Latin American exchange rates. Our results highlight the potential of having misleading public policy when estimates are based in GARCH types of models. This article also complements recent similar findings encountered in European and Asian economies.     

The law and economics of self-dealing

We present a new measure of legal protection of minority shareholders against expropriation by corporate insiders: the anti-self-dealing index. Assembled with the help of Lex Mundi law firms, the index is calculated for 72 countries based on legal rules prevailing in 2003, and focuses on private enforcement mechanisms, such as disclosure, approval, and litigation, that govern a specific self-dealing transaction. This theoretically grounded index predicts a variety of stock market outcomes, and generally works better than the previously introduced index of anti-director rights.     

Why Have Workers Stopped Joining Unions? The Rise in Never‐Membership in Britain

This paper tracks the rise in the percentage of employees who have never become union members (‘never‐member’) since the early 1980s and shows that it is the reduced likelihood of ever becoming a member, rather than the haemorrhaging of existing members, that is behind the decline in overall union membership in Britain. We estimate the determinants of ‘never‐membership’ and consider how much of the rise can be explained by structural change in the labour market and how much by change in preferences among employees.     

Reputation and turnover

We consider a repeated duopoly game where each firm privately chooses its investment in quality, and realized quality is a noisy indicator of the firm's investment. We focus on turnover equilibria in which a low‐quality realization is penalized by lowering future demand of the firm that delivered this quality. We determine when a turnover equilibrium that gives higher welfare than the static equilibrium exists and how this relates to market fundamentals. We also derive comparative statics properties, and we characterize a set of investment levels and, hence, payoffs that turnover equilibria sustain.     

MULTIVARIATE SUBORDINATION OF MARKOV PROCESSES WITH FINANCIAL APPLICATIONS

This paper develops the procedure of multivariate subordination for a collection of independent Markov processes with killing. Starting from d independent Markov processes with killing and an independent d‐dimensional time change , we construct a new process by time, changing each of the Markov processes with a coordinate . When is a d‐dimensional Lévy subordinator, the time changed process is a time‐homogeneous Markov process with state‐dependent jumps and killing in the product of the state spaces of . The dependence among jumps of its components is governed by the d‐dimensional Lévy measure of the subordinator. When is a d‐dimensional additive subordinator, Y is a time‐inhomogeneous Markov process. When with forming a multivariate Markov process, is a Markov process, where each plays a role of stochastic volatility of . This construction provides a rich modeling architecture for building multivariate models in finance with time‐ and state‐dependent jumps, stochastic volatility, and killing (default). The semigroup theory provides powerful analytical and computational tools for securities pricing in this framework. To illustrate, the paper considers applications to multiname unified credit‐equity models and correlated commodity models.
