Baumol’s Cost Disease offers a compelling hypothesis of rising unit costs in stagnant sectors, but increased productivity in progressive sectors may generate the same prediction through income effects. We examine quantity (rather than expenditure) data from the U.S. educational sector to...

Chen et al. (2010) [1] propose a unified method–coordinate-independent sparse estimation (CISE)–that is able to simultaneously achieve sparse sufficient dimension reduction and screen out irrelevant and redundant variables efficiently. However, its attractive features depend on the...

Continuum regression encompasses ordinary least squares regression, partial least squares regression and principal component regression under the same umbrella using a nonnegative parameter Gamma. However, there seems to be no literature discussing the asymptotic properties for arbitrary...

There has been much attention paid to oil security in China in recent years. Although China has begun to establish its own strategic petroleum reserve (SPR) to prevent potential losses caused by oil supply interruptions, the system aiming to ensure China׳s oil security is still incomplete. This...

We firstly combine multi-scale method (MS) and weighted-permutation entropy (WPE) to analyze chaotic, noisy, and fractal time series, and find that MSWPE can distinguish different nonlinear time series and exhibit a better robustness in the presence of higher levels of noise, a task that...

Existing studies disagree over the basic determinants of capital structure in Chinese firms. We identify profitability, industry leverage, asset growth, tangibility, firm size, state control, and the largest shareholding as reliable core factors explaining book leverage. Compared with evidence...

The paper is a continuation of our paper, Wang and Wang (2013) [13], Chen and Wang  [4], and it studies functional inequalities for non-local Dirichlet forms with finite range jumps or large jumps. Let α∈(0,2) and μV(dx)=CVe−V(x)dx be a probability measure. We present explicit and sharp...
