The Swedish model is dying The 2017 OECD Economic Survey of Sweden — presented today in Stockholm by OECD Secretary-General Angel Gurría and Sweden’s Minister of Finance Magdalena Andersson — points out that income inequality in Sweden has been rising since the 1990s. I would say that what we see happen in Sweden is deeply disturbing. The rising inequality is outrageous – not the least since it has to a large extent to do with income and wealth...

Why not make macroeconomics a science? The trouble is, too many theorists — especially in the mainstream of the discipline — have drifted far from the real world. Their ambition has been to build mathematically elegant and internally consistent models of the economy, even if that requires wholly unrealistic assumptions. Granted, just as maps have to simplify complex terrain, theoretical models must ignore aspects of reality to be any use. But there’s a line...

Why reading newspapers makes you stupid Lydon: You say newspapers make us stupid, and I’m not quite clear why. Taleb: Because they always give you an explanation to events so that you have the feeling that you know what’s going on. They tell you the stock market went down, because of fear of a recession, and that’s false causation with uncertainty there. They check their facts, but you can’t check their causes. So, you have the feeling of over-causation...

Uncertainty and the pretty, polite techniques of economics All these pretty, polite techniques, made for a well-panelled Board Room and a nicely regulated market, are liable to collapse. At all times the vague panic fears and equally vague and unreasoned hopes are not really lulled, and lie but a little way below the surface. Perhaps the reader feels that this general, philosophical disquisition on the behavior of mankind is somewhat remote from the...

A Swedish giant has left us Sad, sad, sad, news reached us today. One of Sweden’s greatest actors ever — Björn Granath — passed away today, aged 70. He made many great performances, but the one that has stayed with me more than any other is the portrait of the rebel Erik in Pelle the Conqueror (1987).

Why economists don’t know what every baby knows about scientific methods Limiting model assumptions in economic science always have to be closely examined since if we are going to be able to show that the mechanisms or causes that we isolate and handle in our models are stable in the sense that they do not change when we “export” them to our “target systems”, we have to be able to show that they do not only hold under ceteris paribus conditions and a...

Die Mauer ist weg  [embedded content] Anything you can say about the Berlin Wall is — to paraphrase one of my intellectual heroes — at the same time both too much and not enough.
