This paper analyzes a two-country model with an international investor considering acquisitions of already existing target firms in a high-tax country and a low-tax country. The investor is able to shift profits from one location to another for tax saving purposes. Two systems of corporate...

We analyze individuals with heterogeneous time-inconsistent preferences that consume sin goods and make a savings decision. A government may tax the sin good and provide mandatory health insurance. Due to time-inconsistency, the individual sin good and savings choices in ict internalities. Due...

This paper contributes to resolving the puzzle that in practice most countries use ad valorem (corporate income) taxation, while a large part of the tax competition literature views business taxes as unit (wealth) taxation. We point to the dual role that corporate taxation plays in attracting...

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 may imply the optimal policy to deviate from tax smoothing. Provided accumulated marginal...

This paper studies the formation of self-enforcing global environmental agreements in a world economy with international trade and two groups of countries that differ with respect to fuel demand and environmental damage. It investigates whether the signatories threat to embargo (potential) free...

In a multi-country model with interconnected markets for fossil fuel and deposits some countries fight climate damage by purchasing and preserving fossil fuel deposits, which would be exploited otherwise. We analyze the effectiveness of such a deposit policy, when that policy stands alone or is...

We focus on carbon emissions control in a group of countries to explore the distributional incidence of mixed policies consisting of a joint emissions trading scheme (ETS) and of national emissions taxes overlapping with the ETS. Such policies impact on national welfares through both the...

This paper compares the Kyoto Protocol and the Paris Agreement in the dynamic game of Battaglini and Harstad (2016). The asymmetric Nash solution of this game reflects the Paris Agreement, whereas the symmetric Nash solution reflects the Kyoto Protocol. In a large set of economies, the Kyoto...

This paper studies within a multi-country model with international trade the stability of international environmental agreements (IEAs) when countries regulate carbon emissions either by taxes or caps. Regardless of whether coalitions play Nash or are Stackelberg leaders the principal message is...

In a two-period model with two groups of countries that extract, trade and consume fossil fuel, a climate coalition fights against climate damage by purchasing or leasing deposits to prevent their extraction, and seeks to manipulate the fuel prices in its favor. The deposit-purchase policy is...
