This paper shows that under imperfect competition the welfare effects of indirect tax harmonization may depend crucially on whether taxes are levied by the destination or the origin principle. In a standard model of imperfect competition, while harmonization always makes at least one country...

A fundamental issues in designing any fiscal regime for non-renewable resources is the balance between rent taxes and royalties. This paper reviews the core issues that arise, in terms of both efficient rent extraction and correcting various market failures. Issues of asymmetric information, for...

This paper addresses a key but neglected task in the theory of international taxation, lent increased urgency by growing awareness of the potential gains from tax coordination: the characterization of Pareto-efficient international tax regimes. It shows that the Diamond-Mirrlees theorem on the...

This paper explores the role of trade instruments in globally efficient climate policies, focusing on the central issue of whether border tax adjustment (BTA) is warranted when carbon prices differ internationally. It shows that tariff policy has a role in easing cross-country distributional...

If countries anticipate Bertrand competition in tax rates, they may expend effort that makes some of their tax payers less mobile or increases the mobility of tax payers elsewhere. I provide piecemeal evidence on what activities countries use. I analyse how such activities interact with Bertrand...

We characterize the equilibrium of the all-pay auction with general convex cost of effort and sequential effort choices. We consider a set of n players who are arbitrarily partitioned into a group of players who choose their efforts ’early’ and a group of players who choose ’late’. Only...

It can be advantageous for an office motivated party A to spend effort to make it public that a group of voters will lose from party A’s policy proposal. Such effort is called inverse campaigning. The inverse campaigning equilibria are described for the case where the two parties can...

This paper considers education investment and public education policy in closed and open economies with an extortionary government. The extortionary government in a closed economy chooses an education policy in order to overcome a hold-up problem of time-consistent taxation similar to benevolent...

What is the strategic role of membership in an intergovernmental group with unanimity requirements if the group negotiates with an external player in a setting with incomplete information? Being in such a group has a strategic effect compared to negotiating as a stand-alone player and reduces...

This paper assesses the role of the public sector in adaptation to climate change. We first offer a definition and categorisation of climate change adaptation. We then consider the primary economic principles that can guide the assignment of adaptation tasks to either the private or the public...
