Management in a complex scenario: World Cup,alternative stadiums and demand for tickets

This paper analyses a particular managerial problem that sports clubs face from time to time. The aim is to identify the effects that alternative stadiums and stadiums' features have in ticket prices and demand. Simultaneous equations models by three-stage least square estimator using instrumental variables is the method employed. The findings evidence that alternative stadiums negatively impact attendances, but clubs can offset this effect playing at high-quality alternative stadiums. Results also evidence that fans care about security levels. Some policies for football leagues are discussed as limits in the use of alternative stadiums, league fixtures and hard requirements concerning security.     

Levered and inverse VIX ETP option contract adjustments: No harm,no foul?

The terms of exchange-traded stock option contracts are usually adjusted when corporate actions take place. These adjustments are made to safeguard the value of the outstanding option contracts. Recently, a new type of corporate event has appeared − levered and inverse exchange-traded product issuers are reducing leverage ratios with increased frequency. While such changes directly affect option values, no contract adjustments are made, resulting in windfall transfers of wealth from outstanding long to outstanding short option holders. In one instance alone, the transfer was more than $US100 million. To remedy the problem, we offer a simple contract adjustment procedure.     

Models for individual adoption of eCommerce,eBanking and eGovernment in Spain

This paper analyzes the adoption patterns of selected internet services such as eCommerce, eBanking and eGovernment in Spain. High quality official data from the Survey on Equipment and Use of Information and Communication Technologies in Households (ICT-H) of the National Institute of Statistics are used. The dataset is a cross section of 16,209 individuals for 2016. Theoretical demand models, grounded in a standard neoclassical utility maximization framework, are adapted to these services. Logistic regression techniques allow quantifying the impact of the socioeconomic characteristics of the individual on the adoption of each service. The resulting models are statistically significant and with a high predictive power. Age, education and levels of internet and computer skills are all significant in explaining the adoption of any of the three services; as are gender and income, but just for eCommerce and eBanking. Interestingly, the level of trust in internet is only significant to explain participation in eCommerce. Finally, policy recommendations are suggested, highlighting the desirability of using specific measures for the different socio-demographic groups and income strata.     

Risk aversion,innovation and performance in family firms

An analysis of the effect of family governance on the relationships among risk aversion, innovation and performance is the purpose of this study. Beyond the level of risk and innovation, we are interested in analysing the relationship between them and their influence on performance in family firms. Traditionally, risk-seeking has been associated with innovation and performance. Our results confirm both components to be independent and, furthermore, show relationships with opposite signs as expected in the literature. In a sample of 500 firms, the results confirm an idiosyncratic behaviour in family firms; innovation contributes to performance to a higher extent in family firms, and at the same time, risk aversion is positively associated with performance only in non-family firms.     

Fairness in Financial Markets: The Case of High Frequency Trading

Recent concern over “high frequency trading” (HFT) has called into question the fairness of the practice. What does it mean for a financial market to be “fair”? We first examine how high frequency trading is actually used. High frequency traders often implement traditional beneficial strategies such as market making and arbitrage, although computers can also be used for manipulative strategies as well. We then examine different notions of fairness. Procedural fairness can be viewed from the perspective of equal opportunity, in which all market participants are treated alike. The same rules apply to HFT as to other traders. Another approach to fairness is in the equality of outcomes. Many HFT strategies are beneficial to other market participants, so one cannot categorically denounce the practice as unfair. Other strategies, for both high and low frequency trading, are not. It is thus important to distinguish between the technology and the use of the technology to make judgments on fairness.     

Estimating the size of the shadow economy in Spain: a structural model with latent variables

There has recently been a revival of international interest in measuring the size of the shadow economy. The current study adopts an approach to the Spanish case that is based on the theory of unobservable variables. This methodology involves the estimation of structural models (MIMIC) which analyses a set of causes of the shadow economy while simultaneously taking into account its influence upon a series of indicators. The proposed model permits the determination of a relative evolution over time of the size of the shadow economy, which requires the calibration of the model with an exogenous estimation in order to obtain real values. The exogenous estimation employed is that obtained by a monetary method based on a money demand function. The results show a considerable shadow economy, measuring between 8 and 18.8% of GDP in the period 1976–2002, and demonstrate that the shadow economy is significantly influenced by the tax burden, the degree of regulation and unit labour costs. A positive correlation is obtained between GDP, money demand and the level of the shadow economy.     

Segmenting the Business Traveler Based on Emotions,Satisfaction, and Behavioral Intention

As travel is part of their work, business travelers are assumed to be focused on carrying out a work‐related task, rather than feeling emotionally stimulated during their trip. Due to this belief, there is limited research on consumer emotions within this segment of the travel market. However, not only is business travel an experience and therefore it involves emotions, but many business trips have a strong leisure component and business travel decision making is often emotionally charged. This paper segments the business travel market based on emotions, satisfaction, and behavioral intention. Using a sample of 400 managers in small‐ and medium‐sized companies, the study demonstrates that the relationship between emotions and satisfaction is not unidirectional as far as business tourism is concerned. For two of the four segments, the valence of emotions translated into an opposite level of satisfaction/intention. The segments were found to differ in personal and trip‐related variables.
