We develop a conceptual framework which captures the effect of the VAT system on profit by two effective taxes. This allows (i) predictions of the determinants of voluntary registration and bunching at the registration threshold; (ii) develops a formula for estimating the elasticity of...

Taxes designed to counter unsustainable behaviours that lead to environmental destruction are usually styled as surtaxes on purchase prices. It makes more sense to locate the source of the profits derived from such behaviours and tax them in order to internalize the environmental costs that are...

Analyzing a homogenous household setting with endogenous fertility and endogenous labor supply, we demonstrate that moving from joint taxation to individual taxation and adapting child benefits so as to keep fertility constant entails a Pareto improvement. The change is associated with an...

The literature on the marginal cost of public funds (MCF) and the marginal excess burden is presently a very rich one. A problem with this literature, is that several different measures are interpreted as MCF. This paper derives and compares some commonly used measures, and introduces an...

In this study, we use a simple dynamic general equilibrium model to demonstrate that the tax deductions affect the three elasticities: that of the Laffer curve (the Laffer elasticity, hereafter), taxable income, and the tax revenue. We first decompose the Laffer elasticity, which consists of the...
