This paper investigates the merits of increasing work incentives for low-income workers by shifting part of the tax burden from social security contributions (SSC) to consumption taxes (specifically VAT) in 13 European OECD countries.

We derive an ex post neutral comprehensive income tax on pension schemes equivalent to a Johansson-Samuelson tax that guarantees non-discriminatory treatment of lifetime-dependent and other investments. By separately taxing contributions and benefits, our concept does not require any assumptions...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....

For more than 25 years, the Social Security Trust Fund has been projected to run out of money in 2033 (give or take a few years), potentially causing benefits to be severely reduced in the absence of corrective legislative action. Today (February 2024), projections are made by the Social...
