Tourism is one of the more important sectors for the economy of Galicia (northwest of Spain). The aim of our study is to quantify determinants of Galician domestic tourism demand and their impacts. Additionally, confidence intervals for these impacts are calculated by bootstrapping data. The results show that income, Eastern vacations and the celebration of the Holy Year of the Apostle Saint James have had a relevant positive impact on tourism. There is also a significant positive connection between a meteorological phenomenon, the North Atlantic Oscillation (NAO), and tourism demand. On the other hand, the differential rates of inflation between Galicia and the rest of Spain and the 2008 economic crisis have had a negative effect.  相似文献

This paper investigates whether volatility futures prices per se can be forecasted by studying the fast-growing VIX futures market. To this end, alternative model specifications are employed. Point and interval out-of-sample forecasts are constructed and evaluated under various statistical metrics. Next, the economic significance of the forecasts obtained is also assessed by performing trading strategies. Only weak evidence of statistically predictable patterns in the evolution of volatility futures prices is found. No trading strategy yields economically significant profits. Hence, the hypothesis that the VIX volatility futures market is informationally efficient cannot be rejected.  相似文献

A bootstrapped DEA procedure is used to estimate technical efficiency of 18 Italian airports during the period 2000-2004. Departing from previous studies, we separate the efficiency related to ability to manage airside activities (operational) from that related to the management of all business activities (financial). In general, Italian airports operate at poor levels of efficiency, with slightly better performance in terms of their financial activities. In the current study, selected intrinsic and environmental characteristics are considered as possible drivers of Italian airport performance. In particular, we found that: (i) the airport dimension does not allows for operational efficiency advantages, (ii) on the other hand, the airport dimension allows for financial efficiency advantages for the case of hubs and disadvantages for the case of the smallest airports (iii) the type(s) of concession agreement(s) might be considered as important source of technical efficiency differentials for those airports running marginal commercial activities; (iv) the introduction of a dual-till price cap regulation might create incentives which lead to the increase of financial efficiency at the detriment of the operational performance. Lastly, the development of a second hub (Milano Malpensa), has negatively affected the performance of the country’s national hub (Roma Fiumicino).  相似文献

This paper examines the linkage of real interest rates of a group of Pacific-Basin countries with a focus on East Asia. We consider monthly real interest rates of US, Japan, Korea, Singapore, and Thailand from 1980 to 2006. The impulse response analysis and half-life estimation are conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. It is found that the degree of capital market integration has increased after the Asian financial crisis in 1997. The overall evidence suggests that the crisis has substantially changed the nature of the short run interactions among the real interest rates. Before the crisis, both the US and Japanese capital markets dominated the region. After the crisis, the dominance of the Japanese market has completely disappeared, while the US market remains as a sole dominant player and the Korean market has become more influential.  相似文献

This paper reports on an exploratory research project designed to gain a deeper understanding of the influences on ultraviolet radiation (UVR) behaviours among high‐risk young adults to determine what compromises the adoption of protection measures for this group. A dual approach using focus groups and the Zaltman Metaphor Elicitation Technique was used to provide personal narratives related to UVR behaviour for tertiary education students. Results from both ‘conversations’ were content‐analysed using an iterative ‘bootstrapping’ technique to identify key themes and issues. This exploratory research identified a number of key themes including effect on mood, influence of culture, the value of tans, unrealistic optimism, risk‐orientation, and the role of experience. This group felt that they not been targeted effectively by public health campaigns and did not fully understand the dangers of high‐risk UVR behaviours. Although a number of previous studies have investigated the relationship between knowledge and behaviour, and largely concluded that increases in knowledge do not lead to increases in adoption of protection practices, the preliminary findings of this study reveal that the knowledge and perceived self efficacy of protective practices is extremely high, what is lacking is the perceived threat and thus the motivations to adopt such behaviours. The conclusions drawn from this research indicate that there are a variety of important influencing factors that compromise UVR behaviours, in particular, the lack of perceived seriousness and severity towards long term consequences such as skin cancer. The recommendation to address the imbalance of ‘perceived threat’ and ‘outcome expectations’ is to focus on increasing knowledge of skin cancer, particularly susceptibility to skin cancer and the severity of the condition.  相似文献

UK mutual fund performance: Skill or luck?   总被引:1,自引:0,他引:1  
Using a comprehensive data set on (surviving and non-surviving) UK equity mutual funds, we use a cross-section bootstrap methodology to distinguish between ‘skill’ and ‘luck’ for individual funds. This methodology allows for non-normality in the idiosyncratic risk of the funds — a major issue when considering those funds which appear to be either very good or very bad performers, since these are the funds which investors are primarily interested in identifying. Our study points to the existence of stock picking ability among a relatively small number of top performing UK equity mutual funds (i.e. performance which is not solely due to good luck). At the negative end of the performance scale, our analysis strongly rejects the hypothesis that most poor performing funds are merely unlucky. Most of these funds demonstrate ‘bad skill’. Recursive estimation and Kalman ‘smoothed’ coefficients indicate temporal stability in the ex-post performance alpha's of winner and loser portfolios. We also find performance persistence amongst loser but not amongst winner funds.  相似文献

We estimate non-parametrical one-factor and three-factor international Capital Asset Pricing Models (CAPM) and find strong evidence for rejecting the linear CAPM specification. Furthermore, we find inconsistent linear betas for a series of stocks in the Colombian stock exchange (BVC), supporting the hypothesis of better and consistent fit of non-parametrical versions of the CAPM.  相似文献

Assessment of inequality measurement is the focus for this survey. All measures of inequality must be evaluated based on a set of desirable properties. More importantly, the usefulness of statistical inference for measures of inequality needs examination.  相似文献

Past empirical studies report ambiguous results regarding the magnitude and significance of substitution between different types of smoking tobacco. Since all types of tobacco contain nicotine this is quite surprising. Using a 20-year rotating panel data set of Norwegian households and a multinomial logit model, we find evidence that consumers switch between tobacco types: first, estimated price effects on choice probabilities have mostly expected signs, albeit their statistical significance vary across different metrics, second, household characteristics affect tobacco composition significantly. These findings suggest that consumers’ choices are ‘locked’ when the relative price variation is small, as has been the case in most of the data period, but that larger changes could induce large-scale switching between tobacco types. Our conjecture is that there is a latent potential for switching, which will become manifest if prices change sufficiently. Similar considerations are likely to have relevance for other close substitutes.  相似文献
