Knowledge that Transforms

In the model of this paper a monopoly seller of a durable good holds periodic sales as a means of price discrimination. A new cohort of consumers enters the market in each period, interested in purchasing the good either immediately or after a delay. Within each cohort, consumers vary in their tastes for the good. Under broad conditions, the seller will vary the price over time. In most periods, he will charge a price just low enough to sell immediately to consumers with a high willingness to pay. Periodically, however, he will drop the price far enough to sell to an accumulated group of consumers with a low willingness to pay.

Time-separability of utility means that past work and consumption do not influence current and future tastes. This form of preferences does not restrict the size of intertemporal-substitution effects, but does place constraints on the relative responses of leisure and consumption to changes in relative prices and in permanent income. These constraints are important for evaluating the impact of shifts in expectations about the future, which play a key role in equilibrium models of the business cycle. Further, if consumption and effort are to be positively correlated over the cycle, then equilibrium theories with time-separable preferences predict a procyclical behavior for the real wage rate.

The appeal of using markets as a means of allocating scarce resources stems in large part from the assumption that a market will approximate the competitive ideal. When competition is not a foregone conclusion, the question naturally arises as to how a firm might manipulate the market to its own advantage. This paper analyzes the issue of market power in the context of markets for transferable property rights. First, a model is developed that explains how a single firm with market power might exercise its influence. This is followed by an examination of the model in the context of a particular policy problem--the control of particulate sulfates in the Los Angeles region.

Aside from possible income effects, measures of the maximum amounts people will pay to avoid a loss and the minimum compensation necessary for them to accept it are generally assumed to be equivalent. Unexpectedly wide variations between these sums, however, have been noted in survey responses to hypothetical options. This paper reports the results of a series of experiments that confronted people with actual money payments and cash compensations. The results indicate that the compensation measure of value seems to exceed significantly the willingness to pay measure, which would appear to call into some question various rules of entitlement, damage assessments, and interpretations of indifference curves.

Inflation reduces the effective cost of homeownership and raises the tax subsidy to owner occupation. This paper presents an asset-market model of the housing market and estimates how changes in the expected inflation rate affect the real price of houses and the equilibrium size of the housing capital stock. Simulation results suggest that the accelerating inflation of the 1970s, which substantially reduced homeowners' user costs, could have accounted for as much as a 30 percent increase in real house prices. Persistent high inflation rates could lead ultimately to a sizable increase in the stock of owner-occupied housing.
