This study presents an improvement of the King-Fullerton framework for calculating the marginal effective tax rate (METR) for active owners of closely held corporations in a dual income tax system with income splitting rules. The original King and Fullerton model was not modeled to incorporate...

The UK Government enacted simplification of its tax credit system in 2003. An inter- esting consequence of the reform is that tax credit payments were split between partners in couples, causing a rare wallet to purse transfer. This paper presents evidence on the effects of the reform on family...

The traditional avoidance literature undeservedly neglects tax base distribution as a factor affecting the avoidance price, and generally assumed to be equal to the avoidance cost. In reality, avoidance providers are usually either high-skilled specialists or insiders. The strong collusion thus,...

Heterogeneity is likely to be an important determinant of the shape of optimal tax schemes. This article addresses the issue in a model à la Mirrlees with a continuum of agents. The agents differ in their productivities and opportunity costs of work, but their labor supplies depend only on a...

This paper examines the optimal schedule of marginal tax rates and the design of earned income tax credits. The analysis is based on a structural labour supply model which incorporates unobserved heterogeneity, fixed costs of work and the detailed non-convexities of the tax and welfare system....

Using administrative tax records for UK businesses, we document both bunching in annual turnover below the VAT registration threshold and persistent voluntary registration by almost half of the firms below the threshold. We develop a conceptual framework that can simultaneously explain these two...

For the first time, we exploit quasi-experimental variation to investigate the impact of inheritance taxation on wealth accumulation. Using bunching and difference-in-differences methods, we directly estimate several behavioral responses during lifetime, rather than relying solely on...
