Nobel lesson: value of stabilisation models

Economic fluctuations, in addition to being reflected in GDP numbers, inflation, and unemployment rates, impact household budgets, hiring decisions of companies, and the ability of families to save money. This year’s Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel (2026) , given to Robert E. Hall and Michael Woodford for “microeconomic foundations of macroeconomic stabilisation”, highlights an essential concept — successful economic policies require an understanding of how individual households and businesses make their economic choices.

Governments have spent many years attempting to reduce the size of both the ‘peaks’ (highs) and ‘troughs’ (lows) that occur in the business cycle. In times of low economic activity (which is characterised by weak demand), central banks use their power to cut interest rates; in times of strong economic activity (characterised by strong demand), policy changes may need to be made to restrict further growth.
