Trade liberalisation and effects on pollutive emissions and waste : a general equilibrium assessment for Norway

Abstract:\nThis paper assesses effects of the last decade’s multinational liberalisation of foreign trade, in terms of economic gains and in terms of pollution. By means of a disaggregated intertemporal CGE model for Norway two scenarios with and without the trade reforms are compared. Despite a slight decrease in GDP, emissions of several pollutants rise significantly. This is partly attributable to a modest increase in aggregate welfare, as polluting consumption rise significantly along with reduced labour effort. Further, the trade reforms, in combination with existing policy concessions, result in a long-run structural change in favour of heavy-polluting export industries. As these are large consumers of electricity, prices of clean hydropower rise and cause an economy-wide substitution towards more pollutive energy sources. \nKeywords: Trade Reforms; Welfare; Environment; Intertemporal CGE Model
