We address the long-standing challenge of adding optimal exploration to the classic Hotelling model of a non-renewable resource. We prove that a frontier of critical levels of proven reserves exists, above which exploration ceases, and below which it proceeds at infinite speed.
This article demonstrates that the green bond cannot constitute an incentive to carry out a green project.
Understanding the mechanisms of deforestation is necessary in order to slow or arrest its progress. To accomplish this requires rigorously estimating the demand for deforestation. We contribute to this endeavor by estimating the effect of crop prices on the demand for conversion of land from forest to agriculture in the tropics during the 21st...
