According to this line of defence, all models are false but to some extent ‘approximately true’ – and approximately true models are harmless from the point of view of the realist’s aims … This argument is to a large extent confused. It is correct that there are cases in which a false assumption can indeed […]

The proposition that theoretical models are necessary for understanding our economic system does not imply that having some particular theoretical model automatically means that we understand anything useful. If one is creative in choosing the ‘right’ assumptions and reasonably clever, then one can produce all kinds of results … This potentially creates a problem that […]
There is an element of hypocrisy among DSGE advocates … Long before the advent of DSGE, microeconomic theorists demonstrated that the conditions for the derivation of aggregates from individual choices are so constraining that they cannot possibly be met in a world populated by people. Yet, never to my knowledge have DSGE advocates addressed the […]
Yours truly’s latest book has made it onto Amazon’s lists of best sellers in economics and econometrics. I am — of course — truly awed, honoured and delighted.
It is not possible to determine the scientific method that it is appropriate to employ for a given task (in a particular context) without knowing the nature of the task. And to know the nature of any scientific task it is always essential to have an insight into (i.e., to seek to determine) the nature […]
When we provide such a critique, we often hear another mantra to which many economists subscribe: ‘It takes a model to beat a model.’ On the contrary, we believe that it takes facts and observations to beat a model … If a model fails to answer the problem to which it is addressed, it should […]
Some argue that economics as a science is already pluralist and that the critique of pluralists addresses a strawman. Newly emerged research areas such as behavioral economics are often presented as examples. Yet, to assess the argument that ‘economics is already pluralist’, one has to be explicit about the dimension and degree of plurality that […]
It’s not that we like EVs more. They’re just way better now.

According to Keynes, financial crises are a recurring feature of our economy and are linked to its fundamental financial instability: It is of the nature of organised investment markets, under the influence of purchasers largely ignorant of what they are buying and of speculators who are more concerned with forecasting the next shift of market […]
The recurring pattern in financial crises is more or less the same. For some reason, a shift occurs in the economic cycle (such as war, innovations, new regulations, etc.) that leads to changes in the profit opportunities for banks and companies. Demand and prices rise, pulling more and more parts of the economy into a […]
