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.     

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.
