The purpose of the paper is to provide a discussion of the various approaches for accounting for labour supply responses in microsimulation models. The paper focus attention on two methodologies for modelling labour supply: 1) The discrete choice model. 2) The random utility – random...

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 present an exercise where we identify optimal income tax rules under the constraint of fixed tax revenue. To this end, we estimate a microeconomic model with 78 parameters that capture heterogeneity in consumption-leisure preferences for singles and couples as...

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...

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...

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...

This paper analyses the general equilibrium relationship between increases in tax financed public employment and total employment, emphasizing one income effect: Reallocating employment from the private to the public sector reduces non-labour income in the form of profits distributed to workers,...

The elasticity of taxable income (ETI) is known to represent a summary measure of tax efficiency costs, which means that further information about the behavioral components of the ETI is not required for its use in tax policy design. However, as there are response margins that may cause biases...

The standard static labor supply model ignores that it takes time for individuals to adjust to a taxbenefit reform. A labor supply decision model is developed that allows for lagged responses in terms of state dependence, stemming from preferences, labor market constraints and adjustment costs....

Encouraging effects from random assignments of intensive and high-quality early child care to disadvantaged children have spurred hopes that publicly funded universal child care can improve human development and social mobility. However, in a universal system advantaged parents can improve the...
