For 4 decades I have been trying to deal with, what seems to me to be a contradiction between empirical results. Kahneman and Twersky note two things. One is diagnostic expectations – people over react to useful signals of membership in a group – diagnostic symptoms.  One example is that red hair is diagnostic of […]

I have begun a possibly long series on people’s heuristics and biases when we try to think about probability. I posted one explanation of the Allais Paradox. Click on the link for definitions as I go on assuming earlier posts have been read (this will create problems but I can’t avoid it). Briefly the Allais […]

Heads I win tails you lose. There are criticisms of alleged hypocrisy and alleged virtue signalling. I am convinced that most who criticise “virtue signalling” are, in fact, criticizing virtue. My guess is that there the selfishness and altruism of different people is different and the relatively selfish suspect (correctly) that the relatively altruistic disapprove […]

if long-term interest rate r is less than the trend growth rate of GDP g Yesterday (technically very early today) I promised a post on why long-term Treasury interest rates are very important. In particular it is very important if the long-term interest rate r is less than the trend growth rate of GDP g. […]

Why have they increased so much. The US Treasury constant maturity 10-year interest rate has increased dramatically since the FED started fighting inflation (after falling dramatically during the Covid 19 epidemic). The increase is not unusual — Monetary policy effects GDP and employment through medium and long term interest rates, especially including the interest rate […]

I think the title makes it clear that this will be a rambling confused post. I am typing on with the thought that something is better than nothing and no one has to read this. The first topic – house prices, is in fact one that interests me a lot. I have a regression which […]

“The Fed Makes a Large Rate Cut and Forecasts More to Come” Jeanna Smialak Writes “The Federal Reserve cut interest rates on Wednesday by half a percentage point, an unusually large move and a clear signal that central bankers think they are winning their war against inflation and are turning their attention to protecting the […]

I just heard an advertisement for Kamala Harris in which she said she would raise taxes on the rich and cut taxes for the middle class. I was pleased. I note the empirical fact that, in years when the income tax is constitutional yet the top marginal tax rate is below 69%, nonincumbent Democrats are […]

IN 2020 the US homicide rate increased by 29% the largest percent increase on record. There are different theories of the cause. Some are related to Covid 19 with isolation (not lockdowns there were not lockdowns in the USA) causing increased stress and domestic disputes. The George Floyd associated conflict between police and those they […]

I have thoughts on a typically interesting essay by Brad DeLong. It was sent to project syndicate and also my e-mail inbox. I think I should not quote it at length without paying. His claim is that, whether or not one likes industrial policy, we need it now. Given the 700-word limit, he doesn’t discuss […]
