This paper investigates product-specific scale economies of banks with respect to off-balance sheet operations. The cost benefits from the non-separability of outputs available to banks that imply the role of OBS activities on bank scale economies are also examined. We further test whether the...

This study aimed to explore the combustion kinetics of organic matter in Huadian oil shale using thermogravimetric analysis. Increases in particle size or heating rate shifted the combustion process to a higher temperature, because of mass transfer resistance and thermal hysteresis. An...

In this paper, we investigate cross-correlations between interest rate and agricultural commodity markets. Based on a statistic of Podobnik et al. (2009), we find that the cross-correlations are all significant. Using the MF-DFA and MF-DXA methods, we find strong multifractality in both...

A general class of linearly extrapolated variance estimators was developed as an extension of the conventional leave-one-out jackknife variance estimator. In the context of U-statistic variance estimation, the proposed variance estimator is first-order unbiased. After showing the equivalence...

We investigate the impacts of market structure and bank risk taking on the efficiency of Chinese commercial banks, employing a two-stage semi-parametric data envelopment analysis model. Our empirical results show that the intense market competition compels Chinese commercial banks to develop...

Taking Economic Zone on the Western Coast of the Taiwan Straits as the study area, we use GIS, remote sensing, mathematical statistics and other methods, to analyze the forest pattern and its variation characteristics in Economic Zone on the Western Coast of the Taiwan Straits during the period...

We take three types of tidal marshes in Shanghai City as the study object: tidal marshes in mainland, tidal marshes in the rim of islands, and shoal in Yangtze estuary. On the basis of assessing nutrient quality and environmental quality, respectively, we use soil quality index (SQI) to assess...

In recent years, the study of power-law scaling characteristics of real-life networks has attracted much interest from scholars; it deviates from the Poisson process. In this paper, we take the whole process of aerial inbound operation in a logistics company as the empirical object. The main aim...

In this paper we propose a new methodology in improving the Diffusion Index forecasting model (Stock and Watson, 2002a, 2002b) using hard thresholding with robust KVB statistic for regression hypothesis tests (Kiefer et al., 2000). The new method yields promising results in the context of long...
