In 2007 and 2008 Polish governments introduced a series of reforms which led to a substantial reduction in the tax "wedge" (in Polish: "klin") on labour. The mean ATR on total labour cost was reduced from 41.6% to 34.0%. We show that when considered together the package of introduced reforms...

We investigate bunching at personal tax thresholds over a 40-year period. At kinks, where the marginal tax rate rises, we find bunching among company owner-managers and the self-employed, but not those with only employment income. Notches, where the average rate rises, provide compelling...

In this paper we provide an overview of the literature relating labour supply to taxes and welfare benefits with a focus on presenting the empirical consensus. We begin with a basic continuous hours model, where individuals have completely free choice over their hours of work. We then consider...

Personal taxes and benefits affect the incentive to work over the lifecycle by altering income-age profiles, insuring against adverse shocks, and changing the returns to human capital. Previous work investigating the impact of taxes and benefits on work incentives has tended to ignore these...

This paper provides an empirical account of the dynamic return to work, and how this is affected by taxes and benefits. In doing so we bring the insights from the literature on dynamic labour supply to the issue of estimating the financial return to work and how it is taxed, where the past...

The distributional impact of proposed reforms plays a central role in public debates around tax and transfer policy. We show that accounting for realistic patterns of mobility in employment, earnings and household circumstances over the life-cycle greatly affects our assessment of the...

This paper examines the distributional impact of increases to out-of-work transfers, increases to work-contingent transfers, and increases in higher rates of income tax over the whole of life. We find that, in contrast to what is implied by standard snapshot analyses, increases to...

Identifying the effect of differential taxation on portfolio allocation requires exogenous variation in marginal tax rates. Marginal tax rates vary with income, but income surely affects portfolio choice directly. In systems of individual taxation - like Canada's - couples with the same...

Owner-managed businesses are a fast growing group; how they respond to tax is central to the challenge of how to tax labour relative to capital incomes. We use newly linked UK tax records to estimate how personal taxes affect the real economic activity and tax avoidance of company...

In 1995, the UK government legislated to increase the earliest age at which women could claim a state pension from 60 to 65 between April 2010 and March 2020. This paper uses data from the first two years of this change coming into effect to estimate the impact of increasing the state pension...
