An agreement about a lower bound for admissible tax rates can reduce the equilibrium tax rate (and thus welfare) in tax competition among fully symmetric countries. This is shown in an infinitely repeated game where the stage game describes the standard tax competition model with source-based...

The purpose of the paper is to narrow the gap between the widespread use of voluntary agreements and research on the rationale of such approaches. A typical example are voluntary agreements of many industries to reduce carbon dioxide emissions because of global warming. If the industry...

Recent contributions on tax competition recognize the interaction between both horizontal and vertical tax externalities in a single federation. In this paper, we extend the theoretical analysis to a framework with multiple federations (a Union). We show that the relative size of a federation in...

The paper analyzes under which conditions a partial tax cooperation will be welfare enhancing within the cooperating regions. Starting from the standard symmetric tax competition model, subgroups of regions can form tax cooperations and thereby increase their relevant market share. As the...

This paper investigates efficiency losses caused by independent tax systems and proposes ways of remedying this coordination failure Whereas the harmful effects of tariff competition have been thoroughly explored in the trade policy literature little is known about the externalities that result...

The paper considers governments' public procurement decision as a way of influencing industry structure. In a federation in which capital is mobile and capital taxation is harmonized, a home bias in public procurement can potentially be explained as an effort to increase the capital intensity of...

We extent a solvable version of the core-periphery agglomeration model to four countries located in two regions. The paper shows that there might still be a race to the bottom in capital income tax rates despite agglomeration rents earned by the mobile factor. We find that intra-regional tax...

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...

This paper analyses tax competition and tax coordination in a model where capital flows occur in the form of mergers and acquisitions, rather than greenfield investment. In this framework, we show that differences in residence based taxes do not necessarily distort international ownership...
