Dear OPE comrades, I have a problem, and request for suggestions. I have attached a PDF file of a paper I am writing, entitled "A Note on Rationing, Price Control and Consumer Welfare." For those who don't want to bother with the entire paper, here is an "executive summary." Take an ordinary Cobb-Douglas utility function, and find the relation between (maximized) utility and money income (the constraint constant in the consumer's expenditure equation), in two cases: with, and without, quantity rationing of X and price control. The curves cross at a crucial value of money income, M*. Numerical analysis teases out the value of M* for various values of the elasticities (of utility with respect to X and Y, "all other goods"), and of the ratio of the uncontrolled to the controlled price. Core conclusion: *even within* the (undoubtedly inadequate) framework of orthodox utility theory, it emerges that rationing and price control *help* consumers whose income is below M*, and *hurt* those with incomes above M*. The problem: references. The attached draft has almost no references, and I haven't been able to find sources in the literature that address this. The model is my own work, based on standard micro, as found in any intermediate text. The upper-level texts (Varian, Layard/Walters, Lancaster, e.g.) seem to have nothing on this. Some intermediate texts (David Friedman, e.g.) discuss rationing and price control, but not in utility-theoretic terms, just with supply and demand curves, welfare gain and loss rectangles and triangles, and so forth. And there is a host of journalistic articles on historical instances of rationing. Any specific references, or suggestions on how to proceed, would be greatly appreciated. Thnx, David David Laibman dlaibman@scienceandsociety.com
