The diagnostic tools examined in this article are applicable to regressions estimated with panel data or cross-sectional data drawn from a population with grouped structure. The diagnostic tools considered include (a) tests for the existence of group effects under both fixed and random effects models, (b) checks for outlying groups, and (c) specification tests for comparing the fixed and random effects models. A group-specific counterpart to the studentized residual is introduced. The methods are illustrated using a hedonic housing price regression. 相似文献

This study analyzed the time–frequency relationship between oil price and exchange rate for Pakistan by using measures of continuous wavelet such as wavelet power, cross-wavelet power, and cross-wavelet coherency (WTC). The results of cross-wavelet analysis indicated that covariance between oil price and exchange rate is unable to give clear-cut results, but both variables have been in phase and out phase (i.e. they are anti-cyclical and cyclical in nature) in some or other durations. However, results of squared wavelet coherence disclose that both variables are out of phase and real exchange rate was leading during the entire period studied, corresponding to the 10–15 months’ scale. These results are the unique contribution of the present study, which would have not been drawn if one would have utilized any other time series or frequency domain-based approach. This finding provides evidence of anti-cyclical relationship between oil price and real effective exchange rate; however, in most of the period studied, real exchange rate was leading and passing anti-cycle effects on oil price shocks which is the major contribution of the study. 相似文献

This article is about the strategic use of adat arguments in the politics of large-scale land acquisition. While customary (adat) communities are commonly depicted as small local minorities living in the forests and being guardians of the environment, in many situations such communities occupy a majority position within the district. Majority adat communities are internally differentiated into categories of actors with varying and conflicting interests. This article focuses on Sumba in eastern Indonesia, where state and adat powers are not opposed but historically aligned. We analyse how five common ways of framing adat in Sumba are currently being deployed in land-acquisition politics, in situations supporting plantation land acquisition or protesting against farmers’ land dispossession. We draw attention to what we call ‘strategic adat framing’ as a political activity. The article calls for analysing the historical and social context of local deployments of adat for understanding the impact of current government pro-adat policies. 相似文献

上世纪70年代末80年代初,农村轰轰烈烈实行的农业生产责任制是包产到户,不是土地承包,土地是作为生产资料按人口平均分配的。土地具有稀缺性、气候性、位置性,是一种不动产,其经营方式应是租赁经营。土地承包实际上就是平均分配土地,不是经营方式,其使用价值终结,没有延续性。农村土地应实行租赁经营,农村土地承包法修改为农村土地租赁法,培养具有专业技术的新型农民和从事农业的企业家,广泛应用科学技术发展农村专业化分工。 相似文献

采用面板协整技术,利用1999—2009年中国省级面板数据分析了住宅非市场化供给、住房价格波动与经济波动之间的关系。实证研究表明:住宅非市场化供给和住房价格波动之间存在较强的负相关关系,住宅非市场化供给的增加,能够平抑商品房价格的上涨幅度;住房价格波动与经济波动之间存在显著的正相关关系,住宅非市场化供给的变化能够通过住宅价格的变化,最终会作用于经济增长,进而影响经济波动;地区经济发展水平与房地产市场发育程度的差异,对住宅非市场化供给、住房价格波动与经济波动三者之间的区域关系造成显著影响。 相似文献
