Issues in Global Natural Gas; A Primer and Analysis

Okogu, Bright Erakpoweri - International Monetary Fund (IMF) - 2002

This paper discusses the rising profile of natural gas in global energy, factors constraining its further development, the gas contracting process, and the absence of a global market, which is analyzed in the context of the economic rent in the gas price and the opaque nature of gas contracts. A...
