Estimates of the elasticity of taxable income (ETI) is conventionally obtained by "stacking" three-year overlapping differences in the estimation. In effect, this means that the ETI estimate is an average of first-, second-, and third-year effects. The present paper draws attention to this...

The European competition rules restrict governments' opportunity to differentiate terms of energy accessibility among firms and industries. This easily runs counter with regional and industrial goals of national energy policies. Norway levies a tax on use of electricity, but exempts main...

Given that structural labor supply models continue to play a key role in the process of policy design, it is important to validate their capacity to provide reasonable predictions of alternative hypothetical policy options. Comparing outcomes before and after a realized policy change (such as a...

We present a scheme for analysing income tax perturbations, applied to a real Norwegian tax reform during 2016 - 2018. The framework decomposes the reform into a structural reform part and a tax level effect. The former consists of a distributional impact and a social effi ciency effect measured...

The purpose of this paper is to introduce and adopt a generalised version of Roemer's (1998) Equality of Opportunity (EOp) framework for analysing optimal income taxation. EOp optimal tax rules seek to equalise income differentials arising from factors beyond the control of the individual....

The purpose of this paper is to introduce and adopt a generalised version of Roemer's (1998) Equality of Opportunity (EOp) framework, which we call extended EOp, for analysing second-best optimal income taxation. Unlike the pure EOp criterion of Roemer (1998) the extended EOp criterion allows...

Information about individual choices of heterogeneous agents. Results can for example be used to describe the distributional effects of tax policy change, such as the effects on changes in money metric utility - distributions of equivalent and compensating variation (EV or CV). This type of...

Over the past decade, the question of whether and how to tax household wealth has risen to the forefront of policy debates across the world. Norway belongs to only a handful of countries that (still) levy an annual net wealth tax. We exploit rich Norwegian administrative data to perform...

Are we better or worse off after the Norwegian tax reform of 1992 and how has the reform influenced the income sizes and the distribution of total income? This question denotes our twofold analysis in this paper. We first examine the trends in average income and income distribution in the period...
