Hi David, Thanks. You gave a much better summary of your paper than I did! Picking up on a few points: > The real wage rate, w, is pushed below a customary or standard > level, w*, the workers' social condition deteriorates and they have no > choice but to offer more labor at every wage: the supply curve of labor > shifts outward. The 'dual' of this is when the demand curve for labour (-power) increases, then the real wage rate is pushed above w*. But the corollary hasn't followed historically: i.e. as w has risen, there hasn't in general been a reduction in the quantity of jobs/family or overtime. (I should add, parenthetically, that if wages are 'sticky' in the short-run, then so are the mandatory hours of work/job which are also contractually set.) > The *story* takes off from > there; the Dobb Effect is the effect of the fall in w (below w*) on the > real supply of labor. That is not a tautology. In fact, it may not > even be true! If it is true, it may take effect in too long a time frame > for it to serve as the basis for a policy impact in the short run. And > empirical evidence is not too clear on it (of course, empirical evidence > is not clear on the New Classical story either). One might suggest that the 'propensity to work overtime' and the 'propensity to work more than 1 job' is crucially dependent, given your assumption of fixed wage rates, on the *rate* of inflation. Thus, there might be a 'threshold' rate of inflation beyond which there is a radical shift in these propensities. [What isn't part of this 'story', but was a significant part of the historical experience in many capitalist social formations, was that the more than 1 income earner per family trend was to -- at least some degree -- affected by the feminist movement and the breaking-down of barriers to the entry of women in different segments of the labour market.] > All economic models use some > combination of behavioral assumptions, definitions (tautologies), and > (where appropriate) equilibrium conditions. Not all definitions, though, lead to tautologies. As for equilibrium conditions, I agree that any non-equilibrium model must stipulate equilibrium conditions since there is no other way of knowing whether there is disequilibrium. However, to stipulate equilibrium conditions does not necessarily mean that: a) the model -- or the economy -- is in equilibrium; b) the model -- or the economy -- is headed towards equilibrium; c) if the model -- or the economy -- is in equilibrium that it will stay in equilibrium. > Second, OPE folks need to be clear: this is an attempt at *immanent > critique* of mainstream macroeconomics -- to get under their skin, in > their own terms, and upset the dogma of policy ineffectiveness -- the main > conclusion of the free-market hegemony.

I don't agree. A methodological critique (which is usually what diagram-intensive immanent critiques boil down to) is not a "mooshy evasion". There were no graphs of formulas in Joan Robinson's "The Need for a Reconsideration of the Theory of International Trade" or in the section of the text by Ian Steedman on "The Heckscher-Ohlin-Samuelson Theory of Trade" but they constituted, in my view, a *devastating* critique of H-O-S trade theory. Similarly, does one need graphs and formulas to refute the pernicious doctrine of consumer sovereignty? I think not. To reveal, and thereby hold up for ridicule, the assumptions on which this doctrine is based is sufficient enough ... especially from the standpoint of classroom instruction. The marginalist _economists_ (as distinct from economics students) are the ones for whom no theoretical claim not embellished with formulas (and possibly graphs) is deemed to be "mooshy". But, as the Cambridge Controversy showed, even when they are logically cornered they just blow the critique off. > I simply assume, in this paper, the usual downward sloping AD > curve. *Of course* all of this needs to be questioned in the full light > of Marxist categories.

I don't think that Marxians should necessarily accept the mainstream definitions of 'short-run', long-run', etc. But, if you are asking whether Marxians need to grasp developments over a period of real time normally associated with the 'short-term', then I would say that we need to have such an analysis. Indeed, I would go so far as to say that concrete *class analysis* requires that we analyze both 'short-term' developments and 'micro' topics. How this class analysis is connected to value theory is a trickier topic. > In other words, > should we even bother to try to construct a theory of capitalist behavior > in a period in which productivity, population, and physical capital stocks > in place are all constant? That is using the mainstream definition of 'short-run'. If we think of the 'short-run' in _real_ time then there is no reason to hold all of these variables constant. Tell workers on an assembly line that the productivity of labor (if it is measured conventionally as output/worker/period of time) can't increase in the short-run! They know better. They know that the intensity of labor can, and often does, vary over the short-term. And they have the sweat to prove it! Tell accountants who work for capitalists that the capital stock and its value is constant in the short-run. They know better. They know from experience about the meaning of accelerated depreciated and a rate of technological obsolescence which is not anticipated. > This behavior would then be the basis for a theory > of how the capitalist economy responds in the short run to (capitalist) > government policy moves. More significantly, it could be used as a basis for analyzing short-term labor strategies. > Is this a useful inquiry, or should we simply > assume that it is submerged in the dynamics of accumulation, crisis, etc.? > I am not sure, but I do think the immanent critical strategy is important > to develop in the meantime. The above should indicate that I think it is useful and important. Workers want to know not only about 'long-term' tendencies. They want to understand their _current_ situation as well and what are the likely consequences of different short-run strategies that they might pursue. Surely we should talk about L-R macrodynamics. But, to _only_ talk about macro and the long-run is talking past workers, imo. [NB: that's not what I'm saying David does.] In solidarity, Jerry
