Public Preferences Regarding Government Spending and Taxes

Martin Beznoska German Economic Institute (IW) German Economic Institute (IW)

This study examines public preferences for government spending and taxation using a fully randomised paired conjoint experiment in the 2025 IW-Population-Survey.

A total of 5,293 adults made eight choices between packages varying spending on infrastructure, social welfare, defence and education, combined with variations in the income tax and VAT. Conditional logit estimates show that an additional €20 billion in annual education spending raises a package’s choice probability by 8.3 percentage points. Higher infrastructure investment is also valued positively, while support for additional social welfare and defence spending does not increase further above €10 billion. Tax increases reduce support much more than equivalent tax cuts increase it. Raising the standard VAT rate from 19 to 21 per cent lowers choice probability by 13.5 percentage points. Willingness to finance additional spending through higher taxes is limited. For €10 billion in additional education spending, respondents accept around €11.5 billion in additional income tax or €9.3 billion in VAT. Even here, full tax financing does not yield a statistically established gain in support. Preferences differ by party affiliation and socio-economic characteristics. The findings support prioritizing spending on education in budget reallocations, but do not establish majority support for specific reforms.

A Comparison of Public Revenues Across the Federal States – What Role Do Fiscal Equalization and Other Factors Play?

A Comparison of Public Revenues Across the Federal States

To ensure equivalent living conditions, the federal government influences the revenues of the states and municipalities. Under the fiscal equalization system, financially weak states receive surpluses in the distribution of sales tax revenues, while financially strong states must accept shortfalls.

Public spending in international comparison: Where does Germany stand in comparison to its neighboring regions?

Germany faces numerous political challenges. How these tasks are prioritized is reflected in spending policy. It is not without reason that the budget is often referred to as “politics cast in numbers.”
