The fundamental split between the Austrian school (and some neo-classical allies) with the remainder of economic thought seems to be the assertion that government intervention in the economy is everywhere and in all cases undesirable. This is curious, so long as the method is taken to be primal over the conclusion, as it is a tenant of praxeology to be value neutral - i.e., analysis identifies consequences of a policy but does not form value judgements about them. In this case, Austrian methods cannot self-consistently conclude that government intervention is undesirable, only that intervention produces particular results, to which is added the separate judgement that these results are undesirable.
To examine these results, consider the microeconomic perspective of individual rational actors (which as I understand is a prefered approach in the Austrian school.) On the one hand, there is an individual whose investments yield interest that exceeds a subsistence income. His desire is to maximize the ratio of his interest gains to the prices of the goods he wishes to buy. Whether one subscribes to the Austrian view that the price of the good determines the price of the factors of production, or the contrary mainstream view, his desire to minimize price necessarily entails a desire to minimize wages paid during production. This brings us to the second individual, who does not have significant investments or savings. His desire is to maximize the ratio of his wage to the prices of the goods he wishes to buy- that is, to minimize non-wage factors of production, including interest.
On the face of it, these two desires are very much at odds. Austrian and (neo)classical views include the axioms that, first, the economy tends towards an equilibrium (or what Mises might have termed a strange attractor had he been familiar with later work in chaos theory), and second, that the equilibrium is optimal. However, in light of the two competing actors, it must be asked “optimal for whom?” There can be but one current state of the economy, so if there are alternative optima, government intervention to select the optimum is in principle legitimized.
Various arguments may be proposed that the two actors’ concerns are actually in alignment, such that there is no alternative optimum. The Austrian position on intervention is that it would worsen the situation for all actors, so let us proceed with that and consider how our two actors’ interests might be aligned. The two definitions of benefit were the ratio of interest to price and the ratio of wages to price, so equivalence between them requires that movements in equilibrated interest rates and wages are precisely proportional. Because wage is a factor of price (or price is a factor of wage), mere positive correlation between wages and interest is not enough to eliminate alternative optima. The consequences of this proportionality are negative feedback loops when attempting to manipulate variables, which is consistent with the axiom of a single optimum, but problematic for the Austrian explanation of growth as a natural consequence of free exchange.
As the Austrian model tends to resist disequilibration, what then are the independent variables driving growth? (As growth is a form of disequilibrium.)
