1919 – 2013
James M. Buchanan (1919–2013) was an American economist and Nobel laureate who founded public choice theory, applying economic methodology to political decision-making and institutional analysis. He developed constitutional economics as a framework for evaluating the rules governing collective choice, arguing that rational self-interest shapes political actors just as it shapes market participants. His work fundamentally challenged the assumption that government actors reliably pursue the public good.
