Anthropogenic greenhouse gas emissions are changing the energy balance of our planet. Various climatic feedbacks make the resulting warming over the next decades and centuries highly uncertain. We quantify how this uncertainty changes the optimal carbon tax in a stochastic dynamic programming...

This paper uses annual data to study the interaction of consumer and commodity prices in 15 economies over the period 1850-1913. We find that consumer price inflation in all 15 countries co-moves with a broad measure of changes in commodity prices. Consumer prices comove most strongly with...

This research sheds light on the causal link between commodity price indexes, i.e., the Agricultural Raw Materials Price Index, Industry Input Price Index, Metal Price Index, and Energy Price Index, in the global market, using wavelet coherence, Toda-Yamamoto causality, and gradual shift...
