Classroom Economics
Varoufakis gives a basic definition of instrumental rationality: “A person is instrumentally rational if she applies her resources efficiently in order to satisfy her preferences” (44). Later, he summarizes the equi-marginal principle: “Stop acting when the marginal utility (i.e. the contribution to utility from the last unit of activity) comes as close to (without being less than) the marginal dis-utility (i.e. the losses of utility following that last unit of utility)” and suggests that, “According to instrumental rationality, the rational person chooses the quantity which best satisfies her preferences all things considered (e.g. cost, fatigue, etc.). If preferences are translated into utility, to be instrumentally rational is to maximise utility subject to various constraints (e.g. fatigue, cost, etc.). And since utility is maximised when the Equi-marginal Principle is satisfied, the instrumentally rational person must always respect this principle” (50). Furthermore, Varoufakis notes the neoclassical economic contention that the equi-marginal principle “applies generally to any situation in which you have to choose between different quantities of a single ‘experience'”(51).
My interests are in trying to figure out how these principles might play out in the wired writing classroom: after all, if I’m writing about class, and if one consistent factor across all the definitions of class I’ve seen is that they carry either an explicit or implicit economic component in their definitions of position and mobility, then it would serve me well to attempt to apply the principles of that economic component of the definition of class to what happens in the writing classroom.
Let me offer one more quotation from Varoufakis on neoclassical economic models before I ask a few questions trying to figure out some of the economic workings of the wired writing classroom.
