Con te partirò (personal) Living next to an Opera house sure has its benefits if you love opera. Just twenty minutes ago two lovely opera singers performed Con te partirò on the little piazza in front of my house. Awesome! This version is pretty good too … [embedded content]

For-profit schools — a total disaster To make education more like a private good, [voucher advocates] tried to change the conditions of both supply and demand. On the demand side, the central proposal was that of education ‘vouchers’, put forward most notably by Nobel Prizewinning economist at the University of Chicago, Milton Friedman. The idea was that, rather than funding schools, government should provide funding directly parents in the form of vouchers...

New study shows marginal productivity theory has only a ‘negligible’ link to reality The correlation between high executive pay and good performance is “negligible”, a new academic study has found, providing reformers with fresh evidence that a shake-up of Britain’s corporate remuneration systems is overdue. Although big company bosses enjoyed pay rises of more than 80 per cent in a decade, performance as measured by economic returns on invested capital...

Murray Rothbard on Adam Smith Adam Smith (1723-90) is a mystery in a puzzle wrapped in an enigma. The mystery is the enormous and unprecedented gap between Smith’s exalted reputation and the reality of his dubious contribution to economic thought … The problem is not simply that Smith was not the founder of economics. The problem is that he originated nothing that was true, and that whatever he originated was wrong; that, even in an age that had fewer...

Probability calculus is no excuse for forgetfulness When we cannot accept that the observations, along the time-series available to us, are independent, or cannot by some device be divided into groups that can be treated as independent, we get into much deeper water. For we have then, in strict logic, no more than one observation, all of the separate items having to be taken together. For the analysis of that the probability calculus is useless; it does not...

The search for heavy balls in economics One of the limitations with economics is the restricted possibility to perform experiments, forcing it to mainly rely on observational studies for knowledge of real-world economies. But still — the idea of performing laboratory experiments holds a firm grip of our wish to discover (causal) relationships between economic ‘variables.’ If we only could isolate and manipulate variables in controlled environments, we would...

Economic growth and the size of the ‘private sector’ Economic growth has since long interested economists. Not least, the question of which factors are behind high growth rates has been in focus. The factors usually pointed at are mainly economic, social and political variables. In an interesting study from the University of  Helsinki, Tatu Westling has expanded the potential causal variables to also include biological and sexual variables. In  the report...

Milton Friedman’s critique of econometrics Tinbergen’s results cannot be judged by ordinary tests of statistical significance. The reason is that the variables with which he winds up, the particular series measuring these variables, the leads and lags, and various other aspects of the equations besides the particular values of the parameters (which alone can be tested by the usual statistical technique) have been selected after an extensive process of trial...
