This paper develops a general equilibrium model to measure welfare effects of taxes for correcting environmental externalities caused by domestic trade, focusing on exter- nalities that arise through exports. Externalities from exports come from a number of sources. Domestically owned ships,...

Several empirical studies document the relevance of firm heterogeneity to assess the effect of trade and environmental policy. This paper develops a multi-country and -sector general equilibrium trade model with heterogeneous firms and analyzes the effect of domestic carbon pricing as well as...

A spatial welfare framework for the analysis of the spatial dimensions of sustainability is developed. It incorporates agglomeration effects, interregional trade, negative environmental externalities and various land use categories. The model is used to compare rankings of spatial configurations...

A quota on foreign competition will generally lead to quality-upgrading (downgrading) of the low-quality (high-quality) firm, an increase in average quality, a reduction of quality differentiation, and a reduction of domestic consumer surplus, irrespective of whether the foreign firm produces...

This paper constructs a simple model to explain how trade in vertically differentiated products affects the welfare of the trading countries when product quality can be selected by firms. We specifically devise a model showing that when trade expands a market, firms will intensively invest in...

We analyze the effects of accidents and liability obligations on the incentives of car manufacturers to monopolize the markets for their spare parts. We show that monopolized markets for spare parts lead to higher overall expenditures for consumers. Furthermore, while the manufacturers invest...
