This paper investigates the speed of adjustment of cost efficiency to equilibrium level in the European banking industry. Our analysis provides for the first time insights into the process of convergence across European banking markets as measured by the speed of adjustment of cost efficiency. In particular, we employ a quadratic loss function specification based on forward-looking rational expectations to model the underlying dynamics of efficiency scores in the banking industry of the EU-15 region over the period 1998–2005. Results show that there is considerable variation in the speed of adjustment across banking systems, while over time it appears that continuing efforts to advance financial integration have led to some improvement in the speed of adjustment to the long-run equilibrium. 相似文献

This research explores the distributional and directional predictabilities among Fintech, Bitcoin, and artificial intelligence stocks from March 2018 to January 2021 using nonparametric causality-in-quantile and crossquantilogram approaches. We also examine connectedness across the assets using a quantile VAR approach. The results indicate the existence of bidirectional causality-in-variance between the variables in a normal market. We also find that directional predictability among the assets is oscillatory over time lags. Finally, we observe a strong price connectedness for highly positive and negative changes. These results further document the diversification potential and safe-haven properties of technology-related assets for portfolio investors. 相似文献

We derive recursive formulas for the moments of compound trend renewal sums with discounted claims. An integral expression for the moment generating function of this risk process is then obtained, from which particular distribution functions are found. We extend the compound (deterministic) trend renewal process by assuming a stochastic trend, a stochastic force of net interest and a stochastic dependence between the inter-occurrence times and the severities of the claims. Finally, stochastic dominance ordering is also observed between the compound trend renewal process and an associated non-homogeneous Poisson process. 相似文献

This article analyzes the impact of mobile telephony on economic growth in Africa. It uses panel data on 36 African countries over the period 1995 to 2010, and estimates an econometric model made up of two equations–one expressing output as a function of mobile telephony, and the other, a demand function, reflecting the possibility of a reverse causation from the former to the latter. Given the importance of telecommunication in the development process and the dire state of fixed‐line telephones in Africa, the explosive growth in mobile telephony on the continent could potentially contribute to addressing some of the important challenges it faces today, including the lack of robust economic growth and of poverty alleviation. Employing panel data estimation procedures, this study finds evidence that supports the view that increased mobile penetration contributes to the growth rate of real gross domestic product (GDP). However, the increase in mobile telephone use was not found to have been significantly influenced by GDP growth. © 2014 Wiley Periodicals, Inc. 相似文献

This research is an exploratory study that examines collaboration at the institutional level in the tourism sector of the Central Region, Ghana. The research begins with a review of the key issues related to collaboration in tourism planning and development followed by an extensive exploration of three main issues related to institutional collaboration in tourism in the Central Region. The three main issues are the vision of tourism development shared among stakeholders, collaboration and coordination within the public sector and between the public and private sectors and the factors that constrain and facilitate collaboration and coordination. Using extensive interviews with key stakeholders and reviewing policy documents, the research indicates low levels of collaboration between tourism institutions both within the public sector and across the public–private sectors. This is notwithstanding a shared awareness of the benefits of collaboration among all actors. The research thus contributes interesting insights into the politics of collaboration in tourism destinations. Given tourism's contribution to the Ghanaian economy, it is imperative that efforts are made towards improving the levels of collaboration and coordination between tourism agencies and institutions. 相似文献

This paper investigates the effect of governance on remittances with specific focus on accounting for heterogeneity in the relationship. Using nonparametric kernel methods that are robust to arbitrary forms of non-linearity, heterogeneity and model specification, and six governance measures from the World Governance Indicators (WGI), the relationship is analysed for 109 countries for the period 1996–2014. The findings show that all six measures: voice and accountability, political stability, government effectiveness, regulatory quality, rule of law and control of corruption are significantly related with remittances. Moreover, the relationship is highly nonlinear and heterogeneous across countries or regions, and time. In addition, specific aspects of governance quality matter differently for remittances across each regional groupings. Hence, there is the need for country-specific rather than a one-size fits all governance reform agenda. 相似文献

We establish a set of stylised facts for trade and trading firms in five market services sectors using comparable firm- and activity-level data from four EU countries. Our analysis shows that exports account for much lower shares of overall sales in the services sectors than in manufacturing. This is because fewer firms are engaged in trade in the services sectors and also because within particular sectors firms trade a lower share of their sales on average. Services producers trade mostly goods, but in terms of value, trade in services is much more important to them than to manufacturers. Larger and more productive firms are more likely to be two-way traders and to engage in both goods and services trade. Trade by services firms is somewhat less dominated by firms that both export and import than trade by manufacturing firms. Few firms export many services or to many countries. The value of services exports is increasing in the number of markets served but not necessarily in the number of services traded. 相似文献

Many economists criticize the concept of the composite commodity'of housing that forms the basis of modern urban economics. As a result, much empirical work has been produced that attempts to estimate the household demand for housing and locational characteristics. The purpose of this paper is to take stock of the literature. The theoretical foundations of the literature and the econometric procedures employed are analyzed and critiqued. In addition, the empirical results are examined in order to identify any patterns that exist. The principal conclusion of this survey is that the theoretical basis is sound, but the econometric applications leave much to be desired. One consequence is that the literature has produced few empirical regularities. Another is that more studies using better estimation procedures and better data are needed before it can be safely argued that the composite commodity concept is replaced by the characteristics approach. 相似文献
