The State, Taxes, Social Security

The demographic transition, digitalisation and decarbonisation all pose major challenges for the state's welfare, spending and fiscal policies. In this Research Unit, our researchers use theoretical and empirical analyses as a basis for discussing the merits of proposed reforms and put forward their own solutions. In addition to the fiscal consequences of such measures, they also investigate the incentives they create and the distribution effects for companies and private households. The aim is to develop ways of achieving a sustainable fiscal policy while also providing affordable, effective and efficient insurance against life's major risks: old age poverty, illness and long-term disability. To meet these needs over the long term, it will be necessary to ensure a competitive business environment for the healthcare industry.

Within this research cluster, reform proposals are discussed and original solutions developed based on theoretical and empirical analyses. In addition to fiscal effects, the researchers also examine the incentive and distributional impacts on businesses and households. The goal is to develop strategies for sustainable fiscal policy as well as a viable and efficient system for protecting against the major life risks of old age, illness, and long-term care. To fulfill these objectives in a sustainable manner, competitive business conditions for the industrial healthcare sector are essential, among other factors.

A Comparison of Public Revenues Across the Federal States

Björn Kauder
