Unilateral, second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. The increase in oil demand and acceleration of global warming resulting from a future carbon tax are large if the price elasticities of oil demand are...

Railway networks are characterised by variations in demand on different links. Optimal strategies therefore call for a differentiated treatment of fares, frequencies and vehicle sizes in various links. However, for several reasons, railway operators may apply uniform levels for these decision...
