Envy-free solutions, Non-linear equilibrium and Egalitarian-equivalence for the Package Assignment Problem

The first result in this paper says that given any efficient non-monetary allocation there is a balanced vector of transfers so that the resulting allocation is fair. The second result here says that given any efficient non-monetary allocation there is a pricing function defined on consumption bundles and a balanced vector of transfers so that they together form a non-linear market equilibrium. The first result is used to establish the second. Subsequently we prove the existence of egalitarian equivalent solutions for package assignment problems and shows that they satisfy the “fair share guaranteed” property

Reflections on the EU objectives in addressing aggressive tax planning and harmful tax practices Final Report. CEPS Report November 2019

This Report analyses the EU’s instruments to tackle aggressive tax planning and harmful tax practices. Based on desk research, interviews with stakeholders and expert assessments, it considers the coherence, relevance, and added value of the EU’s approach. The instruments under analysis are found to be internally coherent and consistent with other EU policies and with the international tax agenda, in particular with the OECD/G20 BEPS framework. The Report also confirms the continued relevance of most of the original needs and problems addressed by the EU’s initiatives in the field of tax avoidance. There is also EU added value in having common EU instruments in the field to bolster coordination and harmonise the implementation of tax measures. One cross-cutting issue identified is the impact of digitalisation on corporate taxation. Against this background, the Report outlines potential improvements to the EU tax strategy such as: making EU tax systems fit for the digital era; leading the international debate on tax avoidance; enabling capacity building in Member States and developing countries; strengthening tax good governance in third countries; ensuring a consistent approach at home and abroad; achieving a level playing field for all companies; and increasing tax certainty and legal certainty
