Economists telling fairy tales An important point is implicit. Economics is not hard because of math. The math in even graduate level economics is no greater than in sophomore physics. Classical economics is hard because it can attack social problems in a value-free, cause-and-effect way, and upends the little morality stories that most people use to think about those problems — rents are high because landlords are greedy. John Cochrane Mainstream...

20th anniversary for the euro — no reason for celebration When the euro was created twenty years ago, it was celebrated with fireworks at the European Central Bank headquarters in Frankfurt. Today we know better. There are no reasons to celebrate the 20-year anniversary. On the contrary. Already since its start, the euro has been in crisis. And the crisis is far from over. The tough austerity measures imposed in the eurozone has made economy after economy...

General equilibrium theory — nonsense on stilts General equilibrium is fundamental to economics on a more normative level as well. A story about Adam Smith, the invisible hand, and the merits of markets pervades introductory textbooks, classroom teaching, and contemporary political discourse. The intellectual foundation of this story rests on general equilibrium, not on the latest mathematical excursions. If the foundation of everyone’s favourite economics...

Statistics is no substitute for thinking The cost of computing has dropped exponentially, but the cost of thinking is what it always was. That is why we see so many articles with so many regressions and so little thought. Zvi Griliches

Ett sista glas (personal) År 2018 var — precis som de flesta år — ett år med både glädje och sorg. För mig kommer året ändå alltid att främst förknipppas med att det var året då min bäste vän sen mer än trettio år  — Bengt Nilsson — gick ur tiden. Inga ord kan riktigt beskriva vad man känner när en människa man älskat inte längre finns där. Man minns skratten, glädjen, omtanken, den mäktiga intelligensen, den drastiska humorn, och det starka sociala...

How to re-establish​​ trust in economics as a science Students all over the world are increasingly questioning if the kind of economics they are taught — mainstream economics — really is of any value. Some have even started to question if economics is a science. Two ‘Nobel laureates’ in economics — Robert Shiller and Paul Krugman — have lately tried to respond: Critics of “economic sciences” sometimes refer to the development of a “pseudoscience” of...

Confessions of scientific​ fraud Even with my various “grey” methods for “improving” the data, I wasn’t able to get the results the way I wanted them. I couldn’t resist the temptation to go a step further. I wanted it so badly … I opened the file with the data that I had entered and changed an unexpected 2 into a 4; then, a little further along, I changed a 3 into a 5. It didn’t feel right. I looked around me nervously. The data danced in front of my eyes....

In advanced economics the question would be: ‘What besides mathematics should be in an economics lecture?’ In physics the familiar spirit is Archimedes the experimenter. But in economics, as in mathematics itself, it is theorem-proving Euclid who paces the halls … Economics … has become a mathematical game. The science has been drained out of economics, replaced by a Nintendo game of assumption-making … Most thoughtful economists think that the games on the blackboard and the...

Dags för flumpedagogers självrannsakan I dag kan vi se resultatet av nittiotalets pedagogiska ‘upplysning’. Undersökningar som PISA och TIMSS ger klara besked, den svenska skolan har försämrats på ett sätt som saknar motstycke i internationella mätningar … Det vore kanske på sin plats att vi rannsakade oss själva och den skoldebatt vi fört under de senaste tjugo åren. En sådan avbön från nittiotalets idéer om den goda läraren skulle vara ett väsentligt...
