Carbon pricing decisions by governments are prone to time-inconsistency, which causes the private sector to underinvest in emission-reducing technologies. We show that incentives for decarbonization can be improved if complementing carbon pricing with carbon contracts for differences, where the government commits to pay a fixed carbon price level to the investors. We derive conditions under which the ...
This article analyzes the spatio-temporal effect of the 2013 floods on freight traffic in Germany by using automatic traffic counter data. The methodology uses a proven time-series outlier detection and identification technique to endogenously determine if a counter was affected during the flood and estimate the magnitude and duration of the change in the number of vehicles passing through it. This ...
