Constitutional economics

Constitutional economics studies how constitutional and institutional rules shape economic and political choices, and how those rules can be evaluated and designed.

Constitutional political economy: An approach to political economy that analyzes how political rules and institutions shape collective decisions. It is the broader framework that places constitutional rule choice at the center of political-economic analysis.
Rules of the game: Formal and informal constraints that structure interaction and define permitted actions. Constitutional economics treats these rules as determinants of political and economic behavior.
James M. Buchanan: An American economist who developed public choice and constitutional political economy and received the 1986 Nobel Prize in Economics. His work made constitutional rule choice a central object of economic analysis.
Welfare economics: The study of how economic arrangements affect social welfare and how resources should be allocated. It evaluates outcomes, while constitutional economics also asks how the rules producing them should be chosen.
Fiscal rules: Legal or institutional constraints on government budgets, deficits, spending, or public debt. They illustrate constitutional choices intended to constrain fiscal decision-making across governments.
Public choice: The application of economic reasoning to political behavior, institutions, and collective decision-making. It supplies models of political actors whose incentives constitutional rules are meant to constrain.
Collective action problem: A situation in which individuals have incentives to avoid contributing to a shared goal, despite its collective benefits. Constitutional rules can change incentives that otherwise obstruct collective provision.
Gordon Tullock: An American economist and political scientist known for foundational work in public choice and rent-seeking. His collaboration with Buchanan shaped the field’s early analytical framework.
Positive political theory: The formal study of political behavior and institutions using models of strategic choice. It often explains behavior under existing rules rather than evaluating constitutional alternatives.
Federalism: A system of government that divides authority between a central government and regional governments. Dividing powers across levels of government is a constitutional strategy for limiting and structuring public decisions.
