This study investigates the effect of introducing index futures trading on spot price volatility in Chinese stock market. We employ a recently developed panel data policy evaluation approach (Hsiao, Ching, and Wan, 2011) to construct counterfactuals market volatility, based mainly cross‐sectional correlations between international markets. new method does not need specify particular regression or time‐series model for process around introduction date trading, thus avoids potential omitted...
Abstract Using a difference‐in‐difference approach, we find that restrictions placed on the CSI 300 and 500 index futures trading during recent Chinese stock market crisis deteriorated spot quality, particularly September trade restrictions. Our results can be explained by sudden risk exposure faced alpha‐strategy traders who stop spots after are introduced, thus worsening quality. © 2016 Wiley Periodicals, Inc.

Therapeutic modalities targeting vascular endothelial growth factor (VEGF) have been used to treat neovascularization and macular edema. However, anti-VEGF treatment alone may cause up-regulation of connective tissue (CTGF) in the retina, increasing risk fibrosis tractional retinal detachment. Therefore, this study, we employ a novel dual-target intervention that involves intravitreal injection VEGF inhibitor ranibizumab transfection reagent-treated non-viral vector carrying anti-CTGF short...
Blood-retinal barrier (BRB) breakdown and vascular leakage is the leading cause of blindness diabetic retinopathy (DR). Hyperglycemia-induced oxidative stress inflammation are primary pathogenic factors this severe DR complication. An effective interventional modality against during early needed to curb BRB leakage. This study sought examine protective effects α-Melanocyte-stimulating hormone (α-MSH) on retina hyperpermeability, electrophysiological dysfunction, morphological deterioration...
In the present study, an oligosaccharide SPO-1 from Spirulina platensis was prepared by glycosidase a marine bacterium. The prebiotic activity of on growth Lactobacillus paracasei and Bifidobacterium animalis, its effect human gut microbiota were examined in vitro. molecular weight tetrasaccharide 650.2 Da, it mainly composed glucose with α-type glycosidic linkages. score highest for probiotic strains L. B. animalis. Furthermore, as fermentation proceeded, gradually degraded utilized...
Plateau pikas (Ochotona curzoniae) are high-altitude model animals and famous "ecosystem engineers" on the Qinghai-Tibet Plateau. Pika activities may accelerate degradation of alpine meadows. Nevertheless, little is known about responses bacterial, fungal, archaeal communities, ecosystem multifunctionality to pika perturbations. To address this question, we studied impacts only disturbance combined (pika grazing) ecological networks soil microbial communities multifunctionality. Our results...
A number of studies on the S & P 500 index options market claim that no‐arbitrage assumption cannot be rejected for this because either martingale restriction defined in L ongstaff (1995) by data, or, even when it is rejected, a large proportion violation can explained friction factors. The present study singles out effect inefficiency from testing KOSPI 200 market, which most liquid and active world. Not only using parametric methods adopted previous but also nonparametric enable us to...
We develop the Nelson–Siegel model in context of option‐implied volatility term structure and study time series components. Three components, corresponding to level, slope, curvature structure, can be interpreted as long‐, medium‐, short‐term volatilities. The long‐term component is persistent driven by macroeconomic variables, medium‐term market default risk, financial conditions. three‐factor has superior performance forecasting with better out‐of‐sample forecasts than popular...
