First things first? Austerity, political parties and the composition of public budgets in the German states
研究了德国各州在财政紧缩下如何调整预算支出，发现基础设施投资被削减，而教育、安全和社会保护支出相对增加，且不同政党在紧缩下有不同优先序。
Abstract Political trade-offs are inherent to public budgeting in modern democracies. Faced with limited resources, policymakers must annually decide which projects to fund and which to delay or abandon. In the German federal system, these trade-offs are especially pronounced at the Länder level: State governments have little control over their tax revenues, while the constitutional debt brake prohibits structural deficits. Consequently, Länder cabinets are compelled to reallocate spending in response to fiscal stress. This study is the first to systematically investigate budgetary trade-offs between policy sectors in the German states. It examines how declining revenues and rising interest payments alter the composition of subnational budgets and whether political parties pursue distinct spending priorities under fiscal pressure. To explicitly model budgetary trade-offs, the analysis employs compositional dependent variables and applies seemingly unrelated regressions to a comprehensive panel dataset. The findings show that fiscal deterioration crowds out investment in infrastructure, universities and research. In turn, spending on school-based education, domestic security, and social protection gains in relative importance. Yet parties matter under austerity. Bourgeois governments seek to preserve public investment, whereas left-wing majorities prioritise social policies, including early childhood education and care. By combining a theory-driven approach with innovative methodology, the article advances our understanding of how policymakers adapt to financial constraints in a federal setting with limited fiscal autonomy. It contributes to broader debates on public finance, party politics, and policy prioritisation under austerity.
