Procedures of revenue estimation of changes in the personal income tax are discussed. Using revenue estimates of the 2006 tax cuts in the personal income tax in Norway as an example, we show that estimates of costs of cuts differ substantially when different effects are brought into...

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...

This paper examines the response of husbands' and wives' earnings to a tax reform in which husbands' and wives' tax rates changed independently, allowing me to examine the effect of both spouses' incentives on each spouse's behavior. I compare the results to those of more simplified econometric...

The inequality in pre-tax income increases in Norway in the 1990s, while the distribution of taxes is about unaltered. This means that tax progressivity has decreased in the period, as measured by summary indices of tax progressivity. This paper discusses to what extent this observed decrease in...

elasticity of taxable income with respect to the net-of-tax rate, i.e., one minus the marginal tax <p> rate. We offer new evidence on this matter by making use of a large panel of Swedish tax payers over the period 1991-2002. Changes in statutory tax rates as well as discretionary changes in tax...</p>

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...

Americans work more than Europeans. Using micro data from the U.S. and 17 European countries, we study the contributions from demographic subgroups to these aggregate level dierences. We document that women are typically the largest contributors to the discrepancy in work hours. We also document...

This paper evaluates the tax reforms carried out in Sweden between 1980 and 1991. We use a recently developed nonparametric labor supply function to account for the behavorial responses of the taxed individuals. We decompose the tax reform to study how the separate components influence hours of...
