Universal versus Quantitative
Economic Laws are universal. As Mises explained, contra Caplan, because supply and demand laws - marginal utility, preferring more at a lower price - are universal, it isn't a quantitative matter but a qualitative matter that maximizing output is better achieved with a free market solution. For the given ends (maximizing output), the best means are to allow the free market to work rather than intervene.
However, while this means that markets are better than socialism, does this mean all interventions are bad? Clearly the qualitative result - the end is better achieved with markets than socialism - is true. But how much better? That is the quantitative question. The answer is clear at the system level: a lot better. But, at the intervention level, one must weigh the objectives.
If the objective of a given intervention is only to maximize output, one need not ask the quantitative question: the market will better serve. But, if one has multiple ends: (1) raise the wages of the poorest worker (2) without reducing total output by very much, then the quantitative question surfaces. For, even if the only end is to increase the wages of the poorest worker, there is a time component, and total output will ultimately lead to lower wages in the long run for the poorest worker (if higher output over time leads to higher real wages of the poorest worker, over time).
This is where the Krugmans and Card & Kreugers (and Galbraiths, who dispute the condition) like to fight. Maybe the quantitative aspect isn't large enough to offset the first round effect of the command benefit. When they argue this line, some turn to "natural rights" arguments: it isn't right to command benefits. But an economist must look at the quantitative aspect of the universal truth, and weigh the losses against the benefits. How does total output respond? How does the universal rule of competitive wage setting and profit maximization induce the employer to respond to command wage hikes? How will the benefit accrue - will it at all? To whom will it go?
And hence economics becomes difficult, and dynamic, quantitative and empirical analysis is required. Hat tips to Mises, Caplan and the struggling economists on both sides.
