Νόμπελ Οικονομίας: Τι είναι μακροοικονομική σταθεροποίηση και ποια η συμβολή των Χολ και Γούντφορντ

Robert E. Hall’s and Michael Woodford’s research has generated a paradigm shift in stabilisation policy. New Keynesian models, a result of their research, allow us to explain and quantify how stabilisation policy affects business cycles and are now used by central banks and finance ministries around the world. Since the laureates’ works were published, the models have been developed and refined; this process can be expected to continue as our economies keep changing. The models can easily be adapted to the varying circumstances encountered by households and businesses. The laureates’ research has made it possible to manage major macroeconomic crises far more effectively than before. It has been hugely beneficial during the pandemic and the energy crises of recent years, which have not had such long-term consequences for growth and inflation as in the critical periods of the 1970s. We have not become mired in a catastrophic economic depression like that of the 1930s. Recessions and episodes of high inflation have not disappeared, but they are less long-lasting.

2026 economic sciences laureate Robert E. Hall’s hypothesis was that changes in consumption could not be predicted because they depend on new – and thus unpredictable – information. Hall presented his results in an article in 1978, which was something of a eureka moment for research. His work became key to the development of modern research on consumption. #NobelPrize

2026 economic sciences laureate Michael Woodford’s economic model has made it possible to respond to supply shocks more effectively. Various types of shocks can disrupt the balance between supply and demand. A negative supply shock could be a commodity shortage, while a positive supply shock could be a technological breakthrough that makes the production of large volumes cheaper and easier. A positive demand shock could be good news about the future that increases households’ consumption, and a negative one the opposite news. If the balance is disrupted, it can be reset using a stabilisation policy that reduces demand (to the left) or increases it (to the right). #NobelPrize

2026 economic sciences laureates Robert E. Hall’s and Michael Woodford’s research has made us better equipped to manage economic downturns. They laid the foundation of the New Keynesian paradigm, in which models are built upon microfoundations, which means from the bottom up. Economic outcomes are the result of millions of decisions made at the microlevel by households and businesses. Using models based upon this approach, rather than simply studying the economy from a macro perspective, like a bird’s eye view, Hall’s and Woodford’s research has generated a paradigm shift in the theory of stabilisation policy. #NobelPrize
