The major point of criticism on A-J by T, is that (A-J) . . . involves an error of confirming the movements along the with the shift of the curve (T, p. 257). This point seems to be obvious from Figure 1 in T, p. 258, but it looks like P-C has a serious objection to this (see p. 211). Mathematically the point of T is even simpler. Consider a continuous real-valued function defined on the nonnegative orthant of R2, f(xi, x2). Suppose one of the variables (say xi) is fixed as a, and 4 is defined by
The most fundamental proposition in the price literature is that in industrial markets, especially those which are oligopolistic in structure, are unresponsive to changes in general business conditions, and that this behavior is pervasive. Our study, The Behazior of Industrial Prices, is an examination of the evidence regarding this view. Our central purpose was to ascertain whether administered prices which, as reported by the Bureau of Labor Statistics (BLS), were essentially unresponsive to declines of general business conditions, were in fact unresponsive: that is, our central task was to obtain transaction rather than quoted prices. To that end, we collected buyers' on commodities that met two conditions:
A. The Effective Price of Heroin Traditional representations of demand curves assume that the dollar price of a good is the only significant element of the cost to the consuming individual. For most goods, other aspects of consumption such as transaction costs and uncertainty about quality are assumed to play a minor role. Not so with heroin. Heroin is different because, first, users face significant transaction costs. Often they must search intently for an opportunity to score. In addition, in any attempt to score they risk being arrested or victimized by other addicts. The consequences of these transaction costs include withdrawal symptoms, beatings, and jail. Second, users face quality uncertainties which may be even more significant. The amount of pure heroin and the toxicity of adulterants vary widely among street bags. The possible consequences include fraud and death. Against these possible consequences of purchasing and using heroin, the dollar price may be relatively unimportant.Consequently, in describing the cost of consuming heroin, it is best to speak in terms of an effective price of heroin. The eff ective price is defined as an index including the following elements: dollar price, amount of pure heroin, toxicity of adulterants, access time, and threats of victimization and arrest. Many of these elements are uncertain quantities from the point of view of the consumer.
