The role of tourism is of vital economic importance, particularly for small countries with a privileged geographical location and favourable weather conditions. This paper examines the importance of tourism as a conditioning factor for higher regional growth in Portugal by employing the conditional convergence hypothesis of Barro and Sala-i-Martin, associated with the endogenous growth theory. The panel data estimation approach provides evidence of the positive impact of tourism (through the accommodation capacity) on the growth in per-capita income among the Portuguese regions, increasing the rate of convergence. Therefore, tourism can be considered as an alternative source for stimulating higher regional growth in Portugal, if the supply characteristics of this sector are improved. 相似文献

We extend the concept of piecewise linear histogram introduced recently by Beirlant, Berlinet and Györfi. The disadvantage of that histogram is that in many models it takes on negative values with probability close to 1. We show that for a wide set of models, the extended class of estimates contains a bona fide density with probability tending to 1 as the sample size n increases to infinity. The mean integrated absolute error in the extended class of estimators decreases with the same rate n–2/5 as in the original narrower class. 相似文献

We consider the normalized least squares estimator of the parameter in a nearly integrated first-order autoregressive model with dependent errors. In a first step we consider its asymptotic distribution as well as asymptotic expansion up to order Op(T−1). We derive a limiting moment generating function which enables us to calculate various distributional quantities by numerical integration. A simulation study is performed to assess the adequacy of the asymptotic distribution when the errors are correlated. We focus our attention on two leading cases: MA(1) errors and AR(1) errors. The asymptotic approximations are shown to be inadequate as the MA root gets close to −1 and as the AR root approaches either −1 or 1. Our theoretical analysis helps to explain and understand the simulation results of Schwert (1989) and DeJong, Nankervis, Savin, and Whiteman (1992) concerning the size and power of Phillips and Perron's (1988) unit root test. A companion paper, Nabeya and Perron (1994), presents alternative asymptotic frameworks in the cases where the usual asymptotic distribution fails to provide an adequate approximation to the finite-sample distribution. 相似文献

We exhibit an empirical Bayes test δ* n for a decision problem using a linear error loss in a class of positive exponential families. This empirical Bayes test δ* n possesses the asymptotic optimality, and its associated regret converges to zero with rate n −1 (ln n )6 This rate of convergence improves the previous results in the literature in the sense that a faster rate of convergence is achieved under much weaker conditions. Examples are presented to illustrate the performance of the empirical Bayes test δ* n 相似文献

We investigate whether or not the imposition of a common EC energy-tax will penalize more the poorer Southern European economies and if this will harm convergence at the EC level. We start by surveying briefly the existing studies and empirical evidence. Then we exploit the results obtained when using the macroeconometric HERMES models to simulate the introduction of an energy-tax. Unfortunately, as we only have HERMES results for one Southern European economy, Portugal, our conclusions are limited. Finally, we investigate convergence in Europe and the effects of energy taxation on convergence. We conclude that energy taxation will harm growth all over the EC, penalizing more one of the less developed countries, Portugal, and having most probably adverse effects on convergence.This paper was prepared for presentation at the Conference Energy Tax in Europe organized jointly by the SEO-University of Amsterdam and the DG XII of the CEC and held in Amsterdam on 13th December 1991. I would like to thank the participants in the Conference and two anonymous referees for helpful comments. Of course, the usual disclaimer applies. 相似文献

Summary. This paper provides conditions for the almost sure convergence of the least squares learning rule in a stochastic temporary
equilibrium model, where regressions are performed on the past values of the endogenous state variable. In contrast to earlier
studies, (Evans and Honkapohja, 1998; Marcent and Sargent, 1989), which were local analyses, the dynamics are studied from
a global viewpoint, which allows one to obtain an almost sure convergence result without employing projection facilities.

改革开放40年来,我国地区经济增长收敛现象较为明显。地区人均GDP增长不仅持续上升,而且水平差距也在不断缩小,存在条件收敛现象,并且东部和沿海地区经济增长的"俱乐部收敛"现象显著。进入20世纪90年代后,增长收敛趋势愈发突出,2008年国际金融危机也未影响增长收敛的发展态势。未来要继续坚持改革开放,补上各地制度和要素的短板,积极培育和发展有利于地区人均GDP增长收敛现象产生的一系列基础性因素,以实现区域更加协调发展。 相似文献

Distribution Dynamics of CO<Subscript>2</Subscript> Emissions 总被引:1,自引:0,他引:1
This paper uses nonparametric methods to examine the convergence in CO2 emissions per capita on a sample of 100 countries for the period 1966–1996. Industrial countries show a convergence pattern.
However, there is little evidence of convergence for the whole sample. 相似文献
