Of what use are RCTs? In her interesting Pufendorf lectures Nancy Cartwright presents a theory of evidence and explains why randomized controlled trials (RCTs) are not at all the “gold standard” that it has lately often been portrayed as. As yours truly has repeatedly argued on this blog (e.g. here and here), RCTs usually do not provide evidence that their results are exportable to other target systems. The almost religious belief with which its advocates...

In recent exchanges on Marx and MMT, one question has concerned the capacity of government spending to encourage private investment and promote employment. Some Marxists appear to regard MMT as incompatible with Marx on this question. My own view is that Marx and MMT are compatible, both in general and on this particular question, and that the contributions of both, when viewed together, hold an important long-term social implication. What follows is a set of remarks outlining my position....

Economics — non-ideological and value-free? I’ll be dipped! 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...

David Card and the minimum wage myth Back in 1992, New Jersey raised the minimum wage by 18 per cent while its neighbour state, Pennsylvania, left its minimum wage unchanged. Unemployment in New Jersey should — according to mainstream economic theory’s competitive model — have increased relative to Pennsylvania. However, when ‘Nobel prize’ winning economist David Card and his colleague Alan Krueger gathered information on fast food restaurants in the two...

Does working from home work? .[embedded content] The frequency of WFH [working from home] has been rising rapidly … We report the results of the first randomized experiment on working from home, run in a 16,000- employee, NASDAQ-listed Chinese firm … We found a highly significant 13% increase in employee performance from WFH, of which about 9% was from employees working more minutes of their shift period (fewer breaks and sick days) and about 4% from...

When do regressions give us causality? The issue boils down to this. Does the conditional distribution of Y given X represent mere association, or does it represent the distribution Y would have had if we had intervened and set the values of X? There is a similar question for the distribution of Z given X and Y. These questions cannot be answered just by fitting the equations and doing data analysis on X, Y, and Z. Additional information is needed. From...

The defeat and suppression of the classical perspective — with its evolutionary, institutionalist, and developmental descendants — cleared the way for a dogmatic economics that exalted self-regulating competitive markets … As we have seen, this perspective soon ran into serious — but temporary — difficulties with the Great Depression, mass unemployment, and the rise of Keynes, whose theory is revived in Harvard University economist Stephen A. Marglin’s Raising Keynes …...

For Marx, a currency’s representation of the labor performed in commodity production is indirect, mediated through a ‘money commodity’. The reason for this is that labor performed in commodity production is not directly social but only made so, indirectly, according to the ‘law’ of value under which the concrete properties of diverse labors are abstracted from and the amount of labor socially necessary to produce each commodity is determined. Since the currency, at least from the...
