¿Han sido el IBEX35 y el IPC definiciones financieramente eficientes del portafolio de mercado?

The present paper questions the financial efficiency of the most used market portfolio proxies in Spain and Mexico (IBEX35 and IPC) in order to determine if these can be considered a proper market portfolio proxy. The paper questions if they can be used as “neutrals”, according to Black & Litterman (1992) proposals in portfolio management. For this purpose, two discrete event simulations that use the Markowtiz-Tobin-Sharpe-Linter model (Markowitz, 1987, p.5) are performed with monthly data of the stock members of these indices in a February 2001 to December 2010 time window. The results are compared by using the Sharpe ratio (Sharpe, 1966) and show that the equilibrium assumptions in the market do not hold, leading to conclude that these market portfolio proxies are inefficient.     

Antecedents to complaint behaviour in the context of restaurant goers

Abstract

This article deals with the process by which consumer complaint behaviour is formed. The general aim is to analyse the nature of this type of response to dissatisfaction, describing its development in terms of how it is influenced by a combination of several factors already researched in the literature. The most relevant contributions from the related theoretical work indicate that public and private responses (complaint behaviour) are the most common reactions of consumers when faced with a dissatisfactory experience. A group of determinants which influence these responses in different ways has also been identified. The main objective of this study is to analyse the relationship between the different determinants of complaint behaviour with the aim of identifying the variables which exert the greatest influence.     

Un análisis de la gestión por competencias en la empresa española De la teoría a la práctica

This paper is about the competency management, a technique for human resources management aimed at improving the performance of employees and organization performance. Specifically, there are concerns about the high degree of implementation of this technique and its relationship with management performance in specific industries with various economic outcomes.     

Trade Credit in Small and Medium Size Firms: An Application of the System Estimator With Panel Data

Financing through suppliers is a subject that has been little studied in the economic literature in general and in corporate finance in particular. Although several hypotheses have been put forward to explain the different reasons behind this phenomenon, trade credit is not based on a general theory. This study provides empirical evidence about factors determining the use of trade credit for a sample of small and medium size firms, which are potentially the firms that would follow this financing route, since they are more rationed in credit markets. Using a panel of Canary-Island firms from 1990 to 1996, and by means of specifications with the system estimator, results reveal that trade credit leads to a reduction in asymmetric information between firms and their financial backers, as well as in transaction costs. Furthermore, we confirm the theory that companies with easier access to institutional finance act as a credit channel for those with greater difficulties to obtain external funds.     

Entrepreneurial orientation and international commitment

This paper contributes to the development of the field of international corporate entrepreneurship (ICE) by examining the influences that the time lapse between foundation and first international market entry may have on the development of an entrepreneurial orientation (EO). Moreover, the paper highlights the existence of a positive relationship between the development of an entrepreneurial orientation and both internationalization decision and dimensions (degree, scope) in established companies. Based on a sample of 155 Spanish firms, our findings suggest that an entrepreneurial orientation positively influences a firm’s propensity to internationalize activities. The results obtained confirm the idea that fast entry into foreign markets is positively related to the development of an entrepreneurial orientation in established firms, and that firms with a marked entrepreneurial orientation have higher relative international sales and operate in a greater number of foreign countries.     

Quality of past performance: Impact on consumers’ responses to service failure

The conceptual model developed in this paper for the airline industry examines the relationship between quality of past service performance and consumers’ responses to service failures (causal attributions, emotions and satisfaction). The empirical results obtained indicate that for those consumers with higher perceptions of quality the causes underlying service failures are seen as less stable and less controllable by the firm than the causes identified by consumers with lower perceptions of quality. Attributions about the failure not only influence satisfaction directly but also moderate the effect of quality on satisfaction. We also analyse the mediating effect of negative emotions on the relationship between service failure attributions and consumer satisfaction.

One-sample tests for a generalized Fréchet variance of a fuzzy random variable

A procedure to test hypotheses about the population variance of a fuzzy random variable is analyzed. The procedure is based on the theory of UH-statistics. The variance is defined in terms of a general metric to quantify the variability of the fuzzy values about its (fuzzy) mean. An asymptotic one-sample test in a wide setting is developed and a bootstrap test, which is more suitable for small and moderate sample sizes, is also studied. Moreover, the power function of the asymptotic procedure through local alternatives is analyzed. Some simulations showing the empirical behavior and consistency of both tests are carried out. Finally, some illustrative examples of the practical application of the proposed tests are presented.     

Dynamic gravity: endogenous country size and asset accumulation

Abstract Numerous gravity applications have resorted to panel data econometric techniques over the past decade. However, with the theory of gravity being so far only static, these estimations lack solid structural dynamic foundations. As a consequence, a consensus on a unified dynamic gravity estimation approach is yet to be reached. In this paper, (i) we build the theoretical foundations for a dynamic gravity model, (ii) we provide guidance for gravity‐type estimations with panel data and we consider applications, and (iii) we calibrate and simulate our model to compare its properties with those of the standard, static gravity setup.     

Budget Forecast Deviations in Municipal Governments: Determinants and Implications

This paper analyses the determinants of municipalities’ budget forecast quality, showing opportunistic behaviour influenced by the electoral cycle. Incumbents overestimate revenue to spend more and underestimate expenditure in the quest for popularity and electoral support. Our results suggest that the budget forecast procedure should be made transparent and externally audited or monitored.     

Corruption and total factor productivity: level or growth effects?

This paper adopts a productivity-based perspective in order to study how corruption conditions the efficiency levels of the economies and their TFP growth rate. It attempts to identify the channels through which corruption can influence productivity growth, whether by conditioning improvements in relative efficiency levels or by shifting the production frontier. The results point out that corruption negatively affects both the levels of efficiency at which the economies perform and the growth rate of TFP, suggesting that the negative impact of corruption on technological progress manifest through its influence on human capital.
