Taxation of capital income and wealth designed to redistribute from the rich may harm small open economies with a globalized capital market as investments are distorted. This study shows that raising tax revenue by taxing wealth is less costly than by taxing labor income within a simplified...

This study calculates efficient taxes on fuel and road use designed to combat driving related externalities. The study shows that the efficient road user charge on fuel is below the marginal mileage-related damage to prevent tax avoidance due to an excessive economic driving-style. The current...

A tax on fuel combined with tax exemptions or subsidies for fuel-efficient vehicles is implemented in many countries to fulfill the Paris agreement and to curb mileage-related externalities from road traffic. The present study shows that a tax on fuel should be combined with heavier taxation of...

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...

This article explores whether altruistic preferences toward households in poor high-temperature countries stimulate global warming policies within rich low-temperature countries that avoids damage from global warming. The article analyzes optimal carbon taxes on commodities within such rich...

Taxation of capital income and wealth redistributes from the rich but may harm the Norwegian economy as business investments is distorted. This study shows how to redistribute from the richest without distorting investment decisions of foreign and domestic investors within a simplified model...

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...

In this paper, we study how lower corporate tax rates impact investment by including two novel channels into a DSGE model used for fiscal policy analysis in Norway. We capture both how foreign firms relocate and invest in the country when corporate taxes are reduced and how the inflow of FDI...

Abatement can be performed by measures that have an impact on present emissions, but no lasting effect, and by long-lived infrastructure investments. We study the optimal combination of short and long-lived options for reducing greenhouse gas (GHG) emissions, by specifying abatement cost...

Several studies show cases where the Samuelson rule holds, or where the marginal cost of public funds (MCF) equals one within optimized tax systems. The conditions for the original Samuelson rule to hold in these studies are quite restrictive, and MCF measures employed are not consistent with...
