We propose parametric copulas that capture serial dependence in stationary heteroskedastic time series. We suggest copulas for first‐order Markov series, and then extend them to higher orders and multivariate series. We derive the copula of a volatility proxy, based on which we propose new measures of volatility dependence, including co‐movement and spillover in multivariate series. In general, these depend upon the marginal distributions of the series. Using exchange rate returns, we show that the resulting copula models can capture their marginal distributions more accurately than univariate and multivariate generalized autoregressive conditional heteroskedasticity models, and produce more accurate value‐at‐risk forecasts. 相似文献

Amid increasing interest in firm age and its effects on firm performance, this special issue offers an exhaustive review of the literature and a novel collection of evidence on the effects of firm age on performance, including a special focus of interest on innovation performance, financial performance, exports, survival and growth. This editorial positions the theme in the extant literature, and provides key definitions and challenges ahead in the field of evolutionary economics. It introduces the collection of articles composing the special issue. The papers offer a diversity of country contexts, as well as analytical approaches and methods. They include an exhaustive review of the literature on age and firms’ performance, and present original empirical studies focusing on the effects of age on firms’ economic outcomes on the one hand, and on innovation outcomes on the other hand. While most of the papers use econometric analysis, the level of analysis ranges from firm to individual. 相似文献

For three years in Bolivia (2002–2005) the INNOVA Project finished researching several technologies for sustainable agriculture, started by earlier DFID-funded projects. Before INNOVA started critics suggested that these technologies should be discarded in favour of a demand survey. Instead, INNOVA kept the existing technologies, but judged the demand for them with several methods (CIAL, sondeo technology fair, and others). INNOVA found that there was demand for some of the technologies, but that a survey would have missed much of the demand, which is implicit. That is, people are not initially aware of all their problems or of all the possible solutions. Over the years, farmers made more specific, sophisticated demands on the technologies, which evolved as a result. Demand and supply of farm technology are like two sides of an unfolding conversation. 相似文献

Panel data is used to determine the incidence of airport fees on fares in the Spanish leisure market airlines. We also study its structure through an empirical specification of a pricing and demand equation system. The results show the existence of market power, strategic behavior and density economics. We also demonstrate that airlines pass all the airport fees onto customers by increasing fares. Furthermore, we find that the behavior of airlines in routes with the presence of low cost carriers do not differ from other routes. 相似文献

AbstractThe purpose of this study is to analyse the new processes of tourism growth and its conflicts from the perspective of social movements. First, the urban growth machine analysis model is applied by the systematisation of six projects. Second, the resistance movements against those projects and whether this resistance could be the start of local tourism degrowth policies are examined. The methodology is qualitative, based on documentary analysis, participatory observation, discussion groups and interviews. The case study is the destination of Costa del Sol-Málaga. The results enable the development of the urban growth machine model in tourist destinations. Meanwhile, social movements demystify the argument based on neoclassical economic progress. The social movements condemn the effects of large-scale top-down projects, and implement alternative bottom-up proposals. Although the social movements do not reject tourism, they call for greater control over its impact, denounce unlimited growth, overtourism and the loss of urban quality of life. These movements advocate a lifestyle linked to the everyday space, which they believe is threatened by excessive urban-tourism growth. They are a symptom of the need to devise a proposal using the principles of degrowth. 相似文献

Spain is a home-owner economy, and housing is a key good for determining the cost of living. However, its treatment in indices such as the Spanish Consumer Price Index (CPI) makes it impossible to measure the real impact of housing on the cost of living. This issue is especially relevant at the regional level, where the differences in the housing markets are very substantial. This paper demonstrates the importance of taking account of owner occupied housing in a measure of the cost of living for Spain. 相似文献

Tourism has a leading role in heritage cities and this implies a major challenge. The overall objective of this paper is to evaluate the performance of tourism planning and management with the view of achieving sustainable tourism in the historic center of Santiago de Compostela, Spain. The study addresses topics collected during a long research process of more than 10 years, such as strategic tourism plans, the implementation of quality management systems for tourism, the tourist supply and the regulation of flows. The results show a destination that has introduced alternatives to improve the tourism experience and diversify its offer beyond the Camino de Santiago. There is also growing concern in promoting the sustainability of the historic center. From our point of view, the strengthening of synergies between the different agents involved in the tourism sector of the city has been a key factor in dealing with this situation. However, in this sense, the main problem which is decongesting the tourist flows to the cathedral and its surroundings is still unresolved. 相似文献

In certain institutional contexts, where there are business groups, banks affiliated to these business networks are faced by incentives that might condition their profitability. The objective of this article is to test whether there is a difference between the performance of affiliated banks and that of banks not affiliated to groups, in the context of an emerging market. In particular, a study is made of the case of Mexico in the period 2007–11. Findings suggest that banks affiliated to business groups show less profitability than non-affiliated banks, which may be a consequence of the provision of loans in an internal capital market. 相似文献
