. So when ‘modern’ mainstream economists use their models — standardly assuming rational expectations, Walrasian market clearing, unique equilibria, time invariance, linear separability and homogeneity of both inputs/outputs and technology, infinitely lived intertemporally optimizing representative agents with homothetic and identical preferences, etc. — and standardly ignoring complexity, diversity, uncertainty, coordination problems, non-market clearing prices, real […]

Ekonomijournalistgruppen har en hel del tydliga devota och inställsamma inslag, där många, kanske de flesta, med tiden har valt att gå ”all in” och blivit PR-konsulter eller pressansvariga på något företag. Andreas Cervenka är ett lysande undantag och hans ”Girig-Sverige” är ekonomijournalistik när den är som bäst, kritisk, upplysande och underhållande … Sverige har numera […]

American economist Hyman Minsky described capitalism as a “two price” system. On one side are asset prices—both financial, like government or corporate bonds, and physical like residential or commercial property. On the other, there are consumer prices—goods and services that determine current output and consumer price inflation.   In the contemporary global economy, asset prices […]

I recall, with sadness, a comment made to me by the author of a well-known textbook. Upon being asked whether he accepted my analysis of demand theory as presented first in 1948, the reply was positive. He added that it would not be included in his advanced textbook because “it would upset too many things […]

For although the amount of his own saving is unlikely to have any significant influence on his own income, the reactions of the amount of his consumption on the incomes of others makes it impossible for all individuals simultaneously to save any given sums.

Har ni vägarna förbi Stockholm i morgon tycker jag definitivt ni ska lägga ett par timmar på att besöka ABF-huset! Yours truly har under flera års tid […]

Mainstream economists do not believe that “countries that borrow in their own currency should not worry about government deficits because they can always create money to finance their debt.” Looking at the result from a survey, not a single economist agreed with that statement. If these economists had been right, we would see lots of […]

Visiting economics conferences and seminars, the sessions usually start with the presentation of mathematical-statistical models building on assumptions somewhat analogous to “let us assume that people are green and descending from Mars” — and then long technical discussions follow on how good these models are at making us better understand contemporary societies and economies. Yours […]

Of all the recent failures of the Australian mainstream media, the failure to properly report and analyse the trilateral security partnership known as AUKUS must surely qualify as the most pitiable.

A couple of years ago, Paul Krugman had a piece up on his blog arguing that the ‘discipline of modelling’ is a sine qua non for tackling politically and emotionally charged economic issues: In my experience, modeling is a helpful tool (among others) in avoiding that trap, in being self-aware when you’re starting to let your […]
