Alberto Francesco Alesina was an Italian economist who was the Nathaniel Ropes Professor of Political Economy at Harvard University from 2003 until his death in 2020. He was known principally as an economist of politics and culture, and was famed for his usage of economic tools to study social and political issues. He was described as having “almost single-handedly” established the modern field of political economy, and as a likely contender for the Nobel Memorial Prize in Economic Sciences.

Political economy is a branch of political science and economics studying economic systems and their governance by political systems. Widely studied phenomena within the discipline are systems such as labour markets and financial markets, as well as phenomena such as growth, distribution, inequality, and trade, and how these are shaped by institutions, laws, and government policy. Originating in the 16th century, it is the precursor to the modern discipline of economics. Political economy in its modern form is considered an interdisciplinary field, drawing on theory from both political science and modern economics.
