The paper analyzes resource policies in an economy in which renewable and fossil resources are realistically assumed to be essential inputs to production. Also realistically, the two types of resources are imperfect substitutes whose degree of substitutability can, however, increase over time....

Recently Acemolgu, Aghion, Bursztyn and Hemous (AER 2012) formulated a model in which a high macroeconomic elasticity of substitution between clean and dirty production represents a crucial condition for green growth. Until now it has never been systematically estimated. Using a novel panel of...

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...
