Owing to the vague fluctuation of energy prices from time to time, a new energy model, which considers both the mean-reverting behavior and the long memory property, is proposed in this paper. Since the problem of estimating parameters, in discrete time for this model, plays a central role in forecast inference, the problem of estimating the unknown parameters has been dealt with for the fractional Ornstein–Uhlenbeck process observed discretely. The asymptotic properties of these estimates are also provided. The numerical simulation results confirm the theoretical analysis and show that our method is effective. To show how to apply our approach in realistic contexts, an empirical study of energy in China, namely Daqing crude oil, is presented. The empirical results seem reasonable when compared to the real data. 相似文献

The influence of the transfer payments from the central government to the local governments on the local governments' efforts on taxation must be taken into consideration by every country for the design of the transfer payments. Based on the theoretical analysis on the influence of the transfer payments from the central government to the local governments on the local governments'payments, this paper indicates that the local governments'efforts on taxation depends on the demand elasticity of the district for public goods. It increases with the increase of the elasticityλ.Judge the degree of the local government's efforts on taxation by measureλ. After an empirical analysis on the transfer payments from the central government to the local governments from 2000 to 2004, thins paper gets the conclusion that the local governments'efforts on taxation abates with the increase of supporting payments or with the increase of the ratio of transfer payments to local willing public payments. Under specific circumstances, the higher the ratio of transfer payments to the local fiscal expenditure is, the smaller the local governments' efforts on taxation is under the central payments, whereas the higher the local income is, the higher the efforts is under the eentral payments. Based on this. this paper gives the meanmg of its corresponding policies. 相似文献

This paper presents a careful investigation of the three popular calibration weighting methods: (i) generalised regression; (ii) generalised exponential tilting and (iii) generalised pseudo empirical likelihood, with a major focus on computational aspects of the methods and some empirical evidences on calibrated weights. We also propose a simple weight trimming method for range‐restricted calibration. The finite sample behaviour of the weights obtained by the three calibration weighting methods and the effectiveness of the proposed weight trimming method are examined through limited simulation studies. 相似文献

With the establishment of labor market of China, market is playing a more and mare important role in allocation of human resources. However, with the transition of economy in China and industrial upgrading in recent years, many labor problems have occurred which do harm to the sustainable development of local economy. The paper researches on the labor market issues of China from the perspective of local labor market regulation. Firstly, it reviews the theories of local labor market regulation. And then the main components of local labor market regulation of China are identified and the evaluation index system is established. The results of analysis of the calculated output show that (1) the local labor market regulation of China has an obvious character of gradient distribution geographically and decreases gradually from east to west; (2) of all the regulations, the regulation of the development of human capital has the most significant impact on local economy currently which is followed by the regulation of labor relation and the regulation of market participation. As to the regulation of social security, it has no Significant impact on the development of local economy. 相似文献

In this paper we examine semiparametric efficiency bounds and efficient estimators for the case of a linear local instrument variable (LIV) model under the assumptions studied in Abadie et al. (2002). We apply the semiparametrically efficient estimation method to analyze the relation between bid dispersion and early bidding in an online auction dataset, which is collected from a natural experiment conducted in Nekipelov (2007). The results confirm the theoretical findings developed in Nekipelov (2007). The semiparametric efficient estimation procedure substantially improves the statistical significance of the effect of jump bidding on bid dispersion. 相似文献
