Tomasz Zawisza is an applied economist, with a special interest in the optimal design of taxation and social welfare programs, as well as their intersection with the labour market.
He conducted his doctoral research at the University of Cambridge, England, under the supervision of Professor Hamish Low. During his studies, his main research focus was optimal taxation under multiple tax bases, where there is some opportunity to shift income from one tax base to another. His particular focus was on optimal taxation when there is, in principle, potential to tax employment and self-employment differently.
In other doctoral work, he has examined the evolution of the risk of adverse health shocks over the life-cycle, and the welfare implications of waiting times for the award of disability insurance.
During his PhD, Tomasz was a visiting student at the University of California, Berkeley, and as of 2017, he has an affiliation with the Institute of Fiscal Studies in London. As a Max Weber Fellow, while continuing to develop further his previous research, he aims to undertake a new project which analyses employment contracts between firms and workers where both sides rely on implicit agreements to maintain cooperation.
Throughout his studies, Tomasz has been actively involved in teaching. He has been a teaching fellow at Fitzwilliam College, Cambridge, where he has taught macroeconomics at the undergraduate level, while also acting as teaching assistant for graduate-level computational methods course at the University of Cambridge. He has also taught public economics and statistics at the University of Cambridge to undergraduates.
