Daniel Weishaar is a PhD student at the Center for Economic Studies (CES) at the University of Munich (LMU). His research interests span from public economics and welfare economics to political economy and normative economics. With his research, he wants to contribute to the understanding of i) the measurement of different types of inequality, ii) the perceptions of these inequalities by citizens of different societies, iii) the optimal design of public policies that take the complex nature of inequalities into account, and iv) the broader consequences of such inequalities for societies. For this purpose, he combines theoretical insights from optimal tax models with empirical analyses that are based on existing (administrative) data and specially developed survey experiments. In fall 2022, Daniel Weishaar was a visiting scholar at Columbia University and he visited University of California, Berkeley in spring 2023.
