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.

The Motivation and Effectiveness of Gas Industry Economic Regulation in New South Wales, 1912–39

The oldest industry in Australia subjected to economic regulation is the gas supply industry in the state of New South Wales. In this paper the aims and motivation of the New South Wales Government in establishing the regulatory regime in 1912 and the subsequent effectiveness in achieving them are determined. Initially the regulatory regime was based on ad hoc arrangements, but eventually a more permanent structure was devised that effectively defused political controversy over gas market pricing and stabilised prices rather than substantially lowered them.

Trip Planning and Decision Making of Self-Drive Tourists—

Abstract

Touring holidays are greenhouse gas intensive, and ways are being sought to reduce these emissions in New Zealand. This research seeks to influence rental vehicle tourists' planning and decision making towards shorter travel. Semi-structured interviews (n = 96) were conducted as part of a quasi-experimental approach, in which tourists were “treated” by receiving a purpose-designed tourist map. Three levels of planning and decision making could be distinguished, whereby both cognitive and affective processes were important. The tourist map did not influence tourists' itineraries, but tourists in New Zealand consistently followed a “travel budget” of about 3-5 hours driving per day.
