Evaluating the accuracy of value-at-risk forecasts: New multilevel tests

We propose independence and conditional coverage tests which are aimed at evaluating the accuracy of Value-at-Risk (VaR) forecasts from the same model at different confidence levels. The proposed procedures are multilevel tests, i.e., joint tests of several quantiles corresponding to different confidence levels. In a comprehensive Monte Carlo exercise, we document the superiority of the proposed tests with respect to existing multilevel tests. In an empirical application, we illustrate the implementation of the tests using several VaR models and daily data for 15 MSCI world indices.     

Wine tourism research: a systematic review of 20 vintages from 1995 to 2014

This paper provides a review of 176 papers on wine tourism published between 1995–2014, highlighting research fields, wine regions studied, theory and methodologies used, journals and authors publishing wine tourism research. This paper aims to provide a reference guide for future researchers through a systematic review of wine tourism research over 20 years. The study contributes to the existing literature reviews of wine tourism and consequently, identifies key gaps for further study. Wine production and wine tourism have very different business foci within wineries. However, the findings reveal the importance of strengthening the synergies between wine production and tourism to be successful. In addition, findings revealed different research agendas between New World and Old World wine countries, where the former has a focus on wine tourism while the later on wine production. There has been an increase in theory building which highlights the complexity of the wine tourism experience. Based on this review, the wine tourism research framework developed by Carlsen (2004) has been extended to include two themes: regional development and the experiential wine tourist. The results reveal relevant findings for academics, winemakers and tourism managers regarding the background and future trends of wine tourism.     

What are the main factors attracting visitors to wineries? A PLS multi-group comparison

This article focuses on the study of the main factors attracting visitors, not only new ones, to wineries, and also on how to keep these customers loyal. This research fills a gap in wine tourism literature, taking into account the differences between brand image and destination image as antecedents of brand equity in wine tourism destinations. The empirical analysis has been carried out with two Spanish denominations of origin, Rioja and Navarra, selected by Nielsen’s market share. Particularly, this study draws from a survey of 232 visitors who visited the wineries during the autumn of 2010. The development of a model of wine tourism destination brand equity provides empirical support in order to evaluate the influence of destination image and brand image on brand equity. Before testing the hypotheses, the measuring instrument was evaluated by means of partial least squares regression. A multi-group analysis was carried out to determine the main differences between these two denominations of origin. The paper hereby recommends the creation of alliances among wine companies and tourism industry (hotels, restaurants, active tourism companies, spa resorts, and so on) to succeed in their own businesses. Finally, limitations are outlined to encourage further research.     

Efficiency of venture capital firms: evidence from Spain

In recent years the venture capital (VC) sector has played an increasingly important role in financial systems. In general, this type of specialised financial activity is conducted by two types of operators, VC firms and VC management companies, each with its specific characteristics. The main objective of this paper is to evaluate the operating efficiency of these financial intermediaries in Spain, using data envelopment analysis, and to carry out an exploratory study of the variables that affect their level of efficiency, using a truncated regression model, and taking into consideration the nature of the operator (an approach not previously undertaken). Our analysis reveals, first, differences in the levels of efficiency achieved by VC firms and VC management companies and, second, that the most efficient organisations are those with more diversified ownership structures and which have a portfolio of companies active in the most innovative sectors.     

Consumer service and loyalty in Spanish grocery store retailing: an empirical study

The purpose of this paper is to investigate the effects of consumer service on loyalty in retail establishments. Based on a theoretical discussion regarding the relationship between waiting time, product quality, store atmosphere and loyalty, an empirical research was conducted to test the proposed relationships. Multiple‐item indicators from previous studies were used to measure the constructs. Results from the study provide empirical support, suggesting that consumer service through three dimensions influences loyalty. Research results suggest that consumer service in retail establishments can be viewed as a threshold factor in order to maintain satisfied and loyal customers. Additionally, managers should consider that loyalty depends on waiting time, product quality and store atmosphere. The present study provides useful information on the relationship between consumer service and loyalty in retailing.     

Understanding the identity of Ibiza,Spain

In order to understand a destination brand, it is essential to define what its identity actually is and the dimensions that it is made up of. Kapferer’s brand-identity prism (Kapferer, J. N. (1992). Strategic brand management: New approaches to creating and evaluating brand equity. New York, NY: The Free Press) is used to respond to these questions in the context of Ibiza, Spain. A qualitative analysis was performed using focus groups, considering tourists who had visited Ibiza in the past. The results indicate that the six dimensions of the Ibiza identity prism are embodied in ?????clubs and discotheques, an exciting personality, an atmosphere of harmony, moments of collective fusion, a clubber image, and the figure of a young, liberal tourist who loves to party. This identity is strong and stable over time, with limited possibilities for a radical repositioning.     

The role of coworker support in the relationship between moral efficacy and voice behavior: The case of hospitality students in Ecuador

ABSTRACT

This article explores the relationships among employee moral efficacy, coworker emotional support, coworker instrumental support, and employee voice behavior regarding abusive supervision in the hospitality industry in Ecuador: a high power distance culture. The results indicate that employees’ moral efficacy predicted their voice behavior with regards to abusive supervision and that coworker emotional support strengthened this relation. However, an interaction effect between moral efficacy and coworker instrumental support on voice behavior was not found. This study provides a theoretical extension of the voice literature by introducing the roles of moral efficacy and coworker support, and has practical implications for the hospitality workplace.     

Human capital in OECD countries: Technical change,efficiency and productivity

The aim of this paper is to analyse the role of human capital in the productivity gains of the OECD countries in the period 1965-90, breaking down the productivity gains into technical change and gains in efficiency. For this purpose we use both a stochastic frontier approach and a non-parametric approach (DEA) and calculate Malmquist indices of productivity. The results obtained indicate the existence of both a level effect (a higher level of human capital raises labour productivity) and a rate effect (a higher level of human capital affects positively the rate of technical change) associated with human capital. The differences among countries in endowments of human capital have worked against labour productivity convergence, since the richer countries, thanks to their greater endowment of human capital, have experienced higher rates of technical change.     

PUBLIC SERVICES IN THE AREA OF THE SOCIAL ECONOMY IN ARGENTINA

ABSTRACT*: The author describes the development of the public sector of the social economy in the last few years. The state-owned companies with significant participation in the economic activity of the country were privatized within the so-called State Reform Scheme (Law 23696), beginning in 1990. Privatizations are still being carried out, but the main activities that were formerly in the hands of the state (electricity, transport, public service) are now in the hands of the lucrative private sector (corporations, mainly of foreign origin). The policy regarding the transfer of these companies has not favoured the social economy sector.     

Dollar-denominated accounts in Latin America during the 1990s

In this paper we analyze the evolution of dollar-denominated accounts in Latin America, and how they impact the stability of the banking system and the volatility of macroeconomic aggregates. Our findings reveal that dollar deposits are strongly influenced by depreciation expectations of the local currency even in an environment of fairly low inflation. We also find that having more dollar accounts increases the probability of future crises if the economy is already in a crisis. Finally, our findings suggest that for some macroeconomic aggregates there exists a positive correlation, in the long and short run, between their volatility and the volume of dollar-denominated accounts in the banking system.
