The loss of international competitiveness of domestic industries remains a key obstacle to the implementation of effective carbon prices in a world without harmonized climate policies. We analyze countries’ non-cooperative choices of emissions taxes under imperfect competition and mobile...

We discuss public pension systems in a multi-period overlapping generations model with gerontologically founded human aging and a special focus on occupation-specific morbidity and mortality. We examine how distinct replacement rates for white-collar and blue-collar workers and early retirement...

This paper analyzes the optimal level of public debt when taxes are used not only for funding public expenditures but also for correcting externalities from climate change. Taking into account externalities implies that the optimal policy deviates from tax smoothing. Provided cumulative marginal...

Using a Cournot oligopoly model with an endogenous number of firms and evasion of indirect taxes, this paper shows that more intense competition may have the negative side-effect of eroding tax revenues by increasing tax evasion. This will be the case if market entry costs decrease. A similar...

This paper investigates the choice of apportionment factors under a corporate tax system of Formula Apportionment. In contrast to perceived wisdom, we show that the apportionment formula contains both mobile (capital) and immobile (labor) factors if jurisdictions are granted full fiscal autonomy...

This paper provides a new foundation of soft drink taxation. We abstract from externalities and internalities previously used to justify such taxation and, instead, emphasize that neither explicit nor implicit markets and prices for sugar content can be expected to emerge. Hence, in the absence...

Within a general equilibrium model, this paper identifies a novel animal welfare externality that occurs if the private animal friendliness in a market economy falls short of the social animal friendliness used by the social planner when determining the efficient allocation. The animal welfare...

Incumbent firms have two basic possibilities to improve their competitive position in the product market: investment in R&D and the creation of entry barriers to the disadvantage of potential rivals, e.g. through lobbying activities, campaign contributions, bribes or the adoption of incompatible...
