American economists Robert E. Hall and Michael Woodford were awarded the Nobel Memorial Prize in economics for research that has helped governments and central banks manage economic shocks, including inflation and energy crises. Announcing the winners in Stockholm, the Royal Swedish Academy of Sciences highlighted their contribution to understanding saving and spending decisions. Hall is affiliated with Stanford University, while Woodford is based at Columbia University.
Their separate contributions refined the Keynesian approach to economic management by examining the decisions of households and businesses. Earlier policies emphasised lower interest rates and taxes, alongside increased government spending, to stimulate activity. However, the simultaneous surge in inflation and unemployment during the 1970s exposed weaknesses in assumptions about straightforward economic trade-offs. Hall demonstrated that consumption depends on expectations of future income: optimism encourages spending, but unexpected information can alter expectations, making future consumption virtually impossible to forecast. Woodford established that businesses' pricing decisions depend partly on their expectations of future interest rates, as well as anticipated costs and competitors' prices.
Woodford's research consequently supported clear, credible communication from central banks about their reasoning and intentions. The US Federal Reserve, which sets short-term interest rates, has adopted this practice, known as forward guidance. Its new chair, Kevin Warsh, nevertheless argues that the approach has gone too far and is seeking to curtail such communication. Woodford's models also recommend measures such as higher interest rates following energy price shocks, to prevent inflation from becoming uncontrolled.
