Hall and Woodford win the economics prize for explaining how policy changes behaviour
Robert E. Hall and Michael Woodford share the 2026 economics prize for models that connect household and business decisions to economic stabilization.
A central bank changes more than today’s interest rate when it announces a future policy path.
It can change what households expect to earn, what firms expect to sell and the decisions both make now. The Academy recognizes Hall’s and Woodford’s work building that behaviour into models of the wider economy. [1][3]
The distinction matters when reading the next rate announcement: separate the current setting from the path people expect to follow. A promise about future borrowing costs can influence current spending and prices; its power depends on how people respond. [3][4]
The assumptions make a large difference. In a 2016 model comparison, a promised rate cut five years ahead raised current output by 25 basis points under complete markets, but by 10.3 basis points when households faced income risk and borrowing constraints. Those are simulated responses to the same policy experiment, not measured effects of a real announcement. [4]
