>>That notwithstanding, argumentum ad hominem prima facie is a bullshit 'fallacy'. The argument is inseparable from the person arguing it; if the argument is rebutted at the same time that the person arguing it is attacked for the sheer stupidity of their opinion, then what's the problem?>>
The attack is entirely extraneous to the rebuttal. If a team of monkies working on typewriters comes up with, by chance, a valid and true argument, it is still a good argument.

It is in no sense a fiction. It is an objective, amoral benchmark by which behaviour can be measured. Most people can't even make a fucking rational and informed choice when they are buying a new DVD player but the mass-failure of individuals to act rationally does not denigrate the validity of it.

How is the atomized rational actor an amoral, objective benchmark? The ends sought by even such a rational actor are socially determined, at least in part, as is the context in which such rational action occurs. The benchmark, then, has coded within it its own historical specificity.
Furthermore, if the vast majority of people fail to act rationally, what does such a rational actor tell us about empirical economies?
>>Everything else? If the models are mathematically optimised, anything that deviates from the model represents a reduction in total utility, output, or whatever.>>
But capitalism in practice cannot be mathematically optimized in a such a way. Furthermore, these types of mathematical models take as a given pre-existing power differentials between people and groups and the construction of wants via advertising. We cannot take these things as given if we want to speak of a just or even efficient economy.
>>All functions in the real world are empirically derived.>>
From what I've seen, the majority of economic functions are deductively derrived from a set of assumptions, usually those entailed by "perfect competition".
>>How do you think firms make predictions? They gather business statistics and perform econometric analysis on them, often using regression or more complex statistical methods, to derive models (functions) of various aspects of the business. There is nothing theoretical whatsoever about the notion of the simple cost, revenue, demand and supply functions. In reality, however, the models are much more complex than simple 1 variable linear functions.>>
Okay. This I will give you. However, when we begin to critique the economy from the standpoint of justice or overall efficiency, we then have to examine what these functions mean, beyond thier ability to predict what is most profitable for single firms. It is at this point that we run into our theoretical assumptions.
>>An asset or market has a given level of variability, or risk, irrespective of who measures it. A $5 billion holding of Share X is exposed to the same level of risk, measured by stdev or whatever the holder chooses, as a $5 holding. The magnitude of losses will differ greatly, but both holdings are subject to the same risk.>>
A billionaire investing millions risks little in terms of a potential loss threatening her lifestyle. Someone earning near the poverty line investing hundreds risks not being able to pay rent (she already cannot afford healthcare). Yes, mathematically, the risks are similar, but in practice, they are not.
>>but I sure as hell wouldn't be a little student socialist pimp on the basis of nothing more than 4 introductory courses and whatever biased, completely non-economic ideological drivel that a humanities lecturer taught me. But hey, whatever. Your life.>>
1. What is a socialist pimp?
2. Your idle and erroneous speculation about my academic background is of no consequence.
3. Ad hominems are frowned upon in this forum.
4. Mainstream economics, regardless of its pretensions towards being a natural science, is mired in its own assumptions and fulfills an ideological function. The very notion of non-ideological social science is a fiction to be wield in an attempt to gain power.
5. I never claimed to be an expert.
