Paul Samuelson left us today. He was a unique figure in the field because his work touched so many of the subfields: His mark can be found on microeconomic and macroeconomic theory, international trade, monetary economics, public finance, welfare economics, and economic pedagogy. He literally wrote the book on Economic His theorem with Wolfgang Stolper, the Stolper-Samuelson Theorem, explains which interest are likely to lose out in the opening to trade, even though there are net welfare gains at the national level.
He was sharp and witty to the end, evidenced here in an interview for the Atlantic Monthly where he makes keen insights into the financial crisis, recession, and fiscal response to it. He was an intellectual giant who will be sorely missed.
