The consumptionbased emissions of China are 14% lower than their productionbased emissions. We see quite a regional EastWest split in net exporters and importers: most of Western Europe, the Americas, and many African countries are net importers of emissions whilst most of Eastern Europe and Asia are net exporters. You can find these figures in absolute (tonnes of CO 2) and per capita terms ...
· Cement is a nonstorable input in the medium and long term. The evidence in Chile shows that cement supply and demand are in relative equilibrium, so the demand or supply of this input can measure the activity in the structural construction or work. The aim of this paper is to backcast the series of cement production since January 2009, using as an instrument the connection of the series of ...
