A modern economy is a very complicated system. Since we cannot conduct controlled experiments on its smaller parts, or even observe them in isolation, the classical hard-science devices for discriminating between competing hypotheses are closed to us. The main alternative device is the statistical analysis of historical time-series. But then another difficulty arises. The competing […]

Varje höst håller your truly sedan fler år tillbaka en introduktionskurs i nationalekonomi för blivande gymnasielärare i samhällskunskap. Förutom några av mina egna böcker, står även Klas Eklunds Vår ekonomi på litteraturlistan. Vår ekonomi kom år 2020 ut i sin senaste (15:e) upplaga.

Speaking at an event entitled “How to Trust Economics” at the World Economic Forum in Davos, the ECB chief also suggested […]

Most mainstream economists want to explain social phenomena, structures and patterns, based on the assumption that the agents are acting in an optimizing — rational — way to satisfy given, stable and well-defined goals.

Inflation peaked back in June 2022, only three months after the Fed started hiking interest rates. At that time, the Fed’s policy rate had risen just 75 basis points, and no one knew how much higher it might go. In fact, we have no evidence that monetary policy had any significant effect on the course taken by prices – […]
After being tasked with editing David Ricardo’s Collected Works in 1930, Piero Sraffa, with the assistance of Maurice Dobb, published them between 1951 and 1973. This work earned him the 1961 Söderström Gold Medal from The Royal Swedish Academy of Sciences. For the edition, Sraffa wrote an interesting and thought-provoking introduction. Its purpose was to demonstrate […]
