The texts of the COP 21 Decision and its Annex are scrutinized from the particular point of view of the extent to which economic theoretic concepts can be considered to inspire them. While this is shown to be partially the case in some of the intentions, the texts themselves contain more...

This paper demonstrates, within a simple two-country model of commodity taxation and cross-border shopping, that the tax revenue (welfare) effects of a minimum tax requirement depend crucially on the character of the initial noncooperative tax equilibrium, i.e. whether it is Nash or Stackelberg.

Gino Gancia, Giacomo Ponzetto and Jaume Ventura have written an extremely interesting paper on a topic that is very timely for the global economy. In this article, I will first argue that GPV have succeeded in formalizing their hypothesis, and that while providing very suggestive analytical...

Internationalization offers enhanced opportunities for individuals to place savings abroad and evade domestic saving taxation. This paper asks whether the concomi- tant loss of saving taxation necessarily is harmful. To this end we construct a model of many symmetric countries in which public...

Europe has seen several proposals for tax coordination only in the area of capital income taxation, leaving countries free to adjust their labor taxes. The expectation is that higher capital income tax revenues would cause countries to reduce their labor taxes. This paper shows that such changes...

The ownership nationality of large US multinational companies plays an implicit but important role in the current debate over how such companies should be taxed. This paper identifies that role and investigates what is actually known about where these companies’ shareholders reside

We analyze stability of self-enforcing climate agreements based on a data set generated by the CLIMNEG world simulation model (CWSM), version 1.2. We consider two new aspects which appear important in actual treaty-making. First, we consider a sequential coalition formation process where players...

That climate policies are costly is evident and therefore often creates major fears. But the alternative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are; moreover, they are substitutes. This brings climate policies naturally in the realm...

Several studies found ancillary benefits of environmental policy to be of considerable size. These additional private benefits imply not only higher cooperative but also noncooperative abatement targets. However, beyond these largely undisputed important quantitative effects, there are...

Analyses of public goods regularly address the case of pure public goods. However, a large number of (international) public goods exhibit characteristics of different degrees of publicness, i.e. they are impure public goods. In our analysis of transfers helping to overcome the inefficient...
