This paper studies the effect of an online retailer on spatial tax competition with mobile consumers. Under non-cooperative Leviathan governments, tax treatment of online purchases according to the destination principle mitigates tax competition; tax treatment of online purchases of online...

This paper studies the interaction of a minimum quality standard and exports in a vertical product differentiation model when firms sell global products. If exante quality of foreign firms is lower (higher) than the quality of exporting firms, a mild minimum quality standard in the home market...

This paper studies the effect of a minimum quality standard, a compulsory labeling scheme, and the combination of both instruments in a vertical differentiation model when not all quality dimensions of products can be observed byconsumers. Both a minimum quality standard on the non-observable...

This paper studies the effect of non-compliance with a minimum quality standard on prices, quality, and welfare in a vertical differentiation model. Non-compliance with a minimum quality standard by a low-quality firm reduces quality levels of both firms, increases the price for the high-quality...

This paper studies the effect of an emission tax on the relocation decision in a duopoly with exogenous vertical product differentiation. We establish the relationship between quality difference, relocation cost, and marginal damage of emissions in a two-country-setting for three cases: An...

This paper studies the effect of an emission tax on the relocation decision in a duopoly with exogenous vertical product differentiation. We establish the relationship between quality difference, relocation cost, and marginal damage of emissions in a two-country-setting for three cases: An...

In this paper, we study the rational for an incumbent to launch a second brand when facing potential entry in a market with quality differentiated products and a fringe producer. Depending on market size, costs for a second brand and a potential entrant’s setup cost the incumbent might use a...

This paper studies the effect of an online retailer on spatial tax competition with cross-border shopping. For low fixed cost of online shopping, the online retailer is active in both markets and tax rates are higher in the online equilibrium than in the online equilibrium. For intermediate...

We develop an asymmetric general oligopolistic equilibrium (AGOLE) model, which extends the range of possible applications in general oligopolistic equilibrium modelling. The AGOLE allows to incorporate endogenous and asymmetric marginal utilities of income across countries.As a first exemplary...

We study the welfare and distribution effects of corporate taxation and transfer pricing in an asymmetric general oligopolistic equilibrium trade model. Without profit shifting, an increasing profit tax rate shifts welfare towards the taxing country, where it also decreases real wages, whereas...
