Adverse Selection, Commitment and Exhaustible Resource Taxation

Abstract

Governments design taxation schemes to capture resource rent. However, they usually propose contracts with limited duration and possess less information on the resources than the extractive firms do. This paper investigates how information asymmetry on costs and an inability to commit to long-term contracts affect tax revenue and the extraction path. This paper assumes that governments maximize the tax revenue contingent on the quantity extracted. This study gives several unconventional results. First, when information asymmetry exists, the inability to commit does not necessarily lower tax revenues. Second, under asymmetric information without commitment, an efficient firm may produce during the first period more or less than under symmetric information. Hence, the inability to commit has an ambiguous effect on optimal contract duration. Third, an increase in the discount factor may shift the extraction towards the first period which contradicts Hotelling's rule.

Extracting information or resource? The Hotelling rule revisited under asymmetric information

“…Gaudet, Lasserre, and Van Long () analyze a two‐period model without commitment and private information on the extraction costs but the assumptions that those costs are drawn independently over time rules out the difficult issues of imperfect information revelation that would arise in our context, where private information is persistent. Ing () extends the analysis to the case of persistent types.…”
