Uncertainty — the crucial question

Uncertainty — the crucial question It may be argued … that the betting quotient and credibility are substitutable in the same sense in which two commodities are: less bread but more meat may leave the consumer as well off as before. If this were, then clearly expectation could be reduced to a unidimensional concept … However, the substitutability of consumers’ goods rests upon the tacit assumption that all commodities contain something — called utility — in a greater or less degree;...

Kom gärna och lyssna och diskutera. Behovet av ökad pluralism inom nationalekonomin diskuteras numera intensivt bland ekonomer och studenter världen över. Så ta chansen att lära känna ett av de viktigare heterodoxa alternativen till den förhärskande neoklassiska teoribildningen inom den moderna...

Aggregate production functions — neoclassical fairytales

Aggregate production functions — neoclassical fairytales When one works – as one must at an aggregate level – with quantities measured in value terms, the appearance of a well-behaved aggregate production function tells one nothing at all about whether there really is one. Such an appearance stems from the accounting identity that relates the value of outputs to the value of inputs – nothing more. All these facts should be well known. They are not, or, if they are, their implications are...

On minimum wage and value-free economics

On minimum wage and value-free economics I’ve subsequently stayed away from the minimum wage literature for a number of reasons. First, it cost me a lot of friends. People that I had known for many years, for instance, some of the ones I met at my first job at the University of Chicago, became very angry or disappointed. They thought that in publishing our work we were being traitors to the cause of economics as a whole. David Card Back in 1992, New Jersey raised the minimum wage by 18...

In the long run — economics as ideology

In the long run — economics as ideology Although I never believed it when I was young and held scholars in great respect, it does seem to be the case that ideology plays a large role in economics. How else to explain Chicago’s acceptance of not only general equilibrium but a particularly simplified version of it as ‘true’ or as a good enough approximation to the truth? Or how to explain the belief that the only correct models are linear and that the von Neuman prices are those to which...

When science becomes dogmatism

When science becomes dogmatism Abstraction is the most valuable ladder of any science. In the social sciences, as Marx forcefully argued, it is all the more indispensable since there ‘the force of abstraction’ must compensate for the impossibility of using microscopes or chemical reactions. However, the task of science is not to climb up the easiest ladder and remain there forever distilling and redistilling the same pure stuff. Standard economics, by opposing any suggestions that the...

‘New Keynesianism’ — an uncomfortable trade-off

‘New Keynesianism’ — an uncomfortable trade-off The crucial point however is: market conditions, which are presupposed in the model of intertemporal choice, are not given in reality. Distributing consumption optimally over time depends on the possibility of individuals to lend money on their permanent income, if temporary periods of low market income are to be bridged. Because this perfect financial market does not exist, consumption behaviour necessarily depends strongly on current...
