Using the maximum likelihood method, in order to estimate Half-Normal stochastic frontier production models, entails several practical di±culties that, perhaps, have not been su±ciently emphasised. In employing FRONTIER software, we analyse the case in which the estimation obtained suggests...

Grey system theory can powerfully deal with incomplete and uncertain information. In this paper, we introduced an improved grey GM(1,1) model that integrates residual modification with Markov chain model. By this model, we improved the forecast accuracy of original grey forecast model and...

The paper intends to measure the daily Value-at-Risk (VaR) for Rial-Euro exchange rate fluctuations risk. Since in this case we deal with a single risk factor, so we will not use the Monte Carlo simulation method to measure the VaR and we will only use the parametric and historical simulation...

Insurance companies have to estimate reserves and provisions to cover the payment of either unreported claims or unsettled claims. In this paper, we apply the Chain-Ladder method to obtain a point estimate of reserves, and then we use the bootstrap technique to estimate the margin of error and...

In some circumstances a decision maker, expert, in a group decision making problem cannot express his/her preferences with a unique linguistic fuzzy preference because he/she is dubious into some preferences. In this paper, we present a consensus model for group decision making problems with...

In this paper the importance of word of mouth for marketing management in the twenty-first century will be discussed. After a short introduction, there will be a focus on the demarcations and problems of traditional marketing. Then, in the third section, word of mouth (WOM) and word-of-mouth...

Doctoral dissertations provide a relevant contribution in a field. The general purpose of the dissertation research is to demonstrate research competence and to add something of value to the body of knowledge. This study provides an overview of marketing research in Spain through doctoral...

In recent years researchers have shown a growing interest in vertical interorganisational relations, above all in the Supply Chain. The absence of previous reviews of the literature on this topic, which would allow us to establish the key issues in Supply Chain Management, led us to analyse the...

The health service quality has been discussed in several organizations committed with the development of the programs and actions capable to attend the expectations of their patients. The aim of this work is to analyze the relationship among the variables quality, satisfaction, image, trust and...

This paper examines the impact of the quality of the financial website in the generation of trust that users of the Internet developed into the canal. With this purpose, we discuss the hypothesis that establishes a relationship between both constructs and that it will allow to verify if the...
