As a cleaner,high-efficiency,and low-carbon fuel,natural gas has been an important fuel resource for China.To achieve a substantial increase in natural gas demand,China has sought to reform its natural gas pricing mechanism.Employing a set of unbalanced panel data for China’s 30 provinces covering 1999-2015,this study aims to estimate the evolving price and income elasticities of natural gas demand and explore the effect of natural gas price reform in China.For this purpose,a series of econometric techniques allowing for cross-sectional dependence and slope homogeneity is utilized.The results suggest that although natural gas demand in China still lacks negative price elasticity,the phenomenon is improving.Moreover,the estimates suggest that natural gas demand in China is indeed becoming increasingly sensitive to income changes.Our estimates also provide strong evidence in favor of the effect of natural gas price reform on the change in price elasticity as the price elasticity decreases in five of the seven regions.In addition,the results indicate large variations in the change in price and income elasticities of natural gas demand across China’s regions.Natural gas demand is becoming more price inelastic in Southwest China and Northwest China,while such demand in North China and East China responds less sensitively to income changes.These findings offer several policy suggestions for the reform of China’s natural gas market at the national and regional levels. 展开更多

This paper investigates the relationship between China’s fuel ethanol promotion plan and food security based on the interactions between the crude oil market, the fuel ethanol market and the grain market. Based on the US West Texas Intermediate(WTI) crude oil spot price and Chinese corn prices from January 2008 to May 2018, this paper applies Granger causality testing and a generalized impulse response function to explore the relationship between world crude oil prices and Chinese corn prices. The results show that crude oil prices are not the Granger cause of China’s corn prices, but changes in world crude oil prices will have a long-term positive impact on Chinese corn prices. Therefore, the Chinese government should pay attention to changes in crude oil prices when promoting fuel ethanol. Considering the conduction e ect between fuel ethanol and the food market, the government should also take some measures to ensure food security. 展开更多

Few studies have focused on the cost of acupuncture treatments although acupuncture has become popular in the United States(U.S.). The purpose of the current study was to examine the out-of-pocket costs incurred from acupuncture services based on an online website, Ok Copay.com. We examined descriptive statistics(range, median and 20% intervals) for the cost of acupuncture "first-time visits"and "follow-up visits" in 41 metropolitan regions in the U.S. The acupuncture prices of 723 clinics throughout 39 metropolitan regions were included, except for Birmingham, Alabama and Detroit, Michigan as there was no online data available at the time of the study for these two regions. The cost range for a first-time acupuncture visit was $15–400;the highest median was $150 in Charleston, South Carolina,while the lowest was $45 in St. Louis, Missouri. The top 10 cities for the highest median were:Baltimore, Washington, D.C., New York, San Francisco, San Jose, Boston, Atlanta, Seattle, Portland and Indianapolis, with the median $120, while the median for all 723 clinics was $112. For the follow-up visits,the cost range was $15–300;the highest median was $108 in Charleston, South Carolina, and the lowest$40 in Miami, Florida. The 10 cities with highest median follow-up acupuncture visit costs were: New York, Baltimore, New Orleans, Washington, D.C., Philadelphia, San Francisco, San Jose, Seattle, Boston and Atlanta, with the median $85, while for all 723 clinics the median price was $80. The estimation of the average gross annual income of each acupuncturist from the regions studied was $95,760, while the total annual cost of patients seeking acupuncture services in the U.S. was about $3.5 billion in 2018. 展开更多

This paper has two aims. The first one is to investigate the existence of chaotic structures in the oil prices, expectations of investors and stock returns by combining the Lyapunov exponent and Kolmogorov entropy, and the second one is to analyze the dependence behavior of oil prices, expectations of investors and stock returns from January 02, 1990, to June 06, 2017. Lyapunov exponents and Kolmogorov entropy determined that the oil price and the stock return series exhibited chaotic behavior. TAR-TR-GARCH and TAR-TR-TGARCH copula methods were applied to study the co-movement among the selected variables. The results showed significant evidence of nonlinear tail dependence between the volatility of the oil prices, the expectations of investors and the stock returns. Further, upper and lower tail dependence and comovement between the analyzed series could not be rejected. Moreover, the TAR-TR-GARCH and TAR-TR-TGARCH copula methods revealed that the volatility of oil price had crucial effects on the stock returns and on the expectations of investors in the long run. 展开更多

What Determines China's Grain Imports and Self-sufficiency? The Role of Rising Domestic Costs and Varying World Market Prices

China s grain sectors have faced unprecedented challenges in recent years as the ever-increasing and historically high level of grain output has failed to reduce grain imports. On the contrary, high grain imports and high domestic stock have accompanied historically high domestic output, a situation dubbed the "triple high" phenomenon in current policy discussion. This paper explores the role of widening domestic-world market price gaps in determining the triple high phenomenon.Unlike earlier studies that relied on production capacities, this paper argues that domestic production and demand (hence imports) are functions of domestic and world market prices and proposes an analytical framework to explicitly capture such price gaps under restricted trade linkages in general equilibrium. Following this approach, a set of price scenarios for the 2011-2020 period are constructed and simulated in a computable general equilibrium model. Results from the core scenarios, in which recent domestic and world market price trends are assumed to continue, suggest that further widening price gaps would substantially increase grain imports and reduce domestic output (by 60 million tons) and self-sufficiency ratios from base levels. In the alternative scenarios with larger (smaller) price gaps, we find higher (lower) imports and larger (smaller) decreases in domestic output and self-sufficiency ratios. Such results provide important policy implications as China's agricultural policy undergoes significant adjustment. 展开更多

In this study, a comparison was made between the Capital Asset Pricing Model (CAPM), the most widely used methodology, and an actuarial method with the use of credit default swaps (CDSs) and the method based on the inverse of the multiple P/E. These three models are used to estimate the cost of equity. The comparison was made on a sample of 24 banks selected among the largest for assets in the world (too big to fail banks) belonging to 11 different countries. The results show that the CAPM estimates a premium for the higher risk than the one obtained with the actuarial method and the method based on the inverse of the P/E (except for 2013). 展开更多
