The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2011 was awarded jointly to Thomas J. Sargent and Christopher A. Sims “for their empirical research on cause and effect in the macroeconomy”.
Macroeconomics is often about trying to understand how events (random or expected, private or public-sector generated) impact key aspects of our everyday life – the prices we are charged in shops, the chances we have getting, or losing, a job. For example, what happens to GDP and exchange rates if… central banks announce a rise in interest rates, an earthquake devastates supply lines, governments draw up generous budget expansions? None of this would be possible without carefully thought out models and robust empirical testing. The Nobel prizes awarded to Thomas Sargent and Christopher Sims recognise the huge contribution they have made to tackling such important questions about our economic journeys.
