Panel unit root tests under cross-sectional dependence 总被引:5,自引:0,他引:5
In this paper alternative approaches for testing the unit root hypothesis in panel data are considered. First, a robust version of the Dickey-Fuller t -statistic under contemporaneous correlated errors is suggested. Second, the GLS t -statistic is considered, which is based on the t -statistic of the transformed model. The asymptotic power of both tests is compared against a sequence of local alternatives. To adjust for short-run serial correlation of the errors, we propose a pre-whitening procedure that yields a test statistic with a standard normal limiting distribution as N and T tends to infinity. The test procedure is further generalized to accommodate individual specific intercepts or linear time trends. From our Monte Carlo simulations it turns out that the robust OLS t -statistic performs well with respect to size and power, whereas the GLS t -statistic may suffer from severe size distortions in small and moderate sample sizes. The tests are applied to test for a unit root in real exchange rates. 相似文献

地脉文化也被称为地脉和文脉,是一个地方旅游发展的基石。根据地脉文化与旅游产品关系对比可以将旅游开发分为两类四型:(1)旅游产品扎根于地脉文化发展模式 (根基稳固、主次分明);(2)旅游产品脱离地脉文化发展模式 (左顾右盼、横生枝节)。本文根据这一基本原理对辽宁沿海经济带旅游发展及旅游产品进行了系统分析,总结了辽宁沿海经济带地脉文化旅游开发利用的经验、问题与对策建议。结果显示:辽宁沿海经济带的地脉文化基础有 “海” “滩” “宜” “河” “港” “城” “工” “农” “山” “史”十大方面。 “海” “城” “山”的旅游产品是辽宁沿海经济带各地当前旅游发展主要方向; “滩” “农” “史”旅游产品是辽宁沿海经济带各地当前旅游发展主要方向; “滩”“农”“史”正在发展; “宜”(宜人气候、度假资源)表面发展丰富,实际潜力巨大; “河”(河流、湖泊、水库) “港” (港口) “工”(工业旅游)是被忽视或者发展滞后的地脉文化资源。 相似文献

The wide fluctuations of oil prices from 2003 to 2008 have attracted the interest of academics and policymakers. A popular view is that these fluctuations were caused by speculative bubbles due to the increased financialization of oil futures markets. This hypothesis, however, is difficult to examine since the fundamental price of oil is unobservable and, therefore, econometric evidence in favor of bubbles may actually be due to misspecified market fundamentals. In this paper, we extend two recently proposed methodologies for bubble detection that alleviate this problem by using market expectations of future prices. Both methodologies provide no evidence of speculative bubbles. 相似文献

This article employs methodologies based on fractional integration and cointegration to analyse the time-series properties of merger and acquisitions (M&A) activity and crude oil prices in the US from 1980 to 2012. Our results indicate that an increase in the crude oil price produces a significant increase in the M&A data between 2 and 3 months after the initial shock. 相似文献

This paper demonstrates that the framing of post-war Kowloon Walled City through photos has been dominated by the maps commonly used to represent this Chinese enclave in colonial Hong Kong as a place. Inspired by and extending Wylie’s (2009) argument that emptiness and presence are equally important, this paper uses basic GIS techniques and hitherto unpublished archival materials to help (a) argues that the colonial government’s mindset of clearly defining the spatial boundary of the city, which is a subtle admission of an officially and diplomatically denied otherness in ownership, created the city as a quasi-cadastral unit; and (b) explains how this shaped the framing of the landscape of the city by promoting investment and trade in high-rise housing development units. The government did not destroy its walls. When these were physically destroyed, it did not ignore the walls’ original alignments but treated the city as a planning unit, as if they still existed. 相似文献

By using both macro‐ and micro‐level data, this paper investigates how wages and prices evolved during Japan's lost two decades. We find that downward nominal wage rigidity was present in Japan until the late 1990s, but disappeared after 1998 as annual wages became downwardly flexible. Moreover, nominal wage flexibility may have contributed to Japan's relatively low unemployment rates. Although macro‐level movements in nominal wages and prices seemed to be synchronized, such synchronicity is not observed at the industry level. Therefore, wage deflation does not seem to be a primary factor of Japan's prolonged deflation. 相似文献

The univariate statistical properties of agricultural price series need to be examined as a first step in the analysis of price transmission mechanisms. However, in the case of weekly price series, increasingly available, the testing procedures usually applied in this step are not suitable to deal with evolving seasonal effects. In this study, a method of testing for seasonal unit roots in weekly series of agricultural prices is described. When the deterministic seasonal component does not remain constant over time, the restricted evolving spline model (RESM) is shown to be a useful parametric formulation to capture the deterministic seasonal pattern. Therefore, the RESM model should be included as a deterministic component in auxiliary regression for unit root tests at seasonal frequencies. This proposal is applied to three weekly series of Canary Islands banana prices. From the standard seasonal unit root tests, the null hypothesis is failed to be rejected at the 5% or 10% significance level at some seasonal frequencies for each one of the series. Once critical values are obtained by simulation exercises when the RESM model is included, the hypotheses of unit root are rejected at each one of the seasonal frequencies for all of the three series. 相似文献
