Quantile serial dependence in crude oil markets: evidence from improved quantilogram analysis with quantile wild bootstrapping

We examine the quantile serial dependence in crude oil prices based on the Linton and Whang’s quantile-based portmanteau test which we improved by means of quantile wild bootstrapping (QWB). Through Monte Carlo simulation, we find that the quantile wild bootstrap-based portmanteau test performs better than the bound testing procedure suggested by Linton and Whang. We apply the improved test to examine the efficiency of two crude oil markets – WTI and Brent. We also examine if the dependence is stable via rolling sample tests. Our results show that both WTI and Brent are serially dependent in all, except the median quantiles. These findings suggest that it may be misleading to examine the efficiency of crude oil markets in terms of mean (or median) returns only. These crude oil markets are relatively more serially dependent in non-median ranges.     

利用可调油嘴实现掺水量合理定量化的探讨

将抽油机井井口控制掺水量的闸门或档板改装设计成可调油嘴,使单井掺水量的控制更加方便灵活,减少岗位工人的劳动强度,同时对合理控制单井回油温度,提高和稳定掺水系统压力很有效。     

Allocating and taxing rights to state-owned minerals

Is Indonesia using the most effective possible strategies to derive revenue from its mineral resources? Auctions and work program bidding are the main ways of allocating mineral leases. In addition to the company taxes applied to all companies, governments can raise revenue from minerals owned by the state through auctions, royalties and rent taxes paid by private firms, and through dividends from state-owned firms. Indonesia uses work program bidding to allocate leases, and its production-sharing contracts are roughly equivalent to a rent tax at a high rate. This paper considers these options for raising revenues from mineral resources. It argues that efficiency and government revenue would both be increased if Indonesia relaxed direct controls on the operations of mining companies, and allocated leases by means of auctions, combined with a much lower rate of rent tax or, better still, a royalty.

Oil price forecasting under asymmetric loss

Based on the approach developed by Elliott et al. (2005), we found that the loss function of a sample of oil price forecasters is asymmetric in the forecast error. Our findings indicate that the loss oil price forecasters incurred when their forecasts exceeded the price of oil tended to be larger than the loss they incurred when their forecast fell short of the price of oil. Accounting for the asymmetry of the loss function does not necessarily make forecasts look rational.     

我国石油战略储备体系建设的若干思考

石油战略储备是关系到我国国家安全的重大问题。一方面，要建立和完善实物储备或现货储备，即讨论和呼声较高的石油战略储备，进一步完善相关制度设计；另一方面，还应抓紧建设战略储备体系的短板——石油期货储备。通过建立石油期货市场，加快推进石油期货交易，把金融安全与石油安全合并考虑，把石油现货储备、期货储备与外汇储备密切结合起来，建立外汇储备与石油储备的转换机制，使我国规模庞大的外汇储备服从、服务于国家的经济安全，提高国家的石油保障能力，从根本上保障我国的石油安全。
