A GUIDE TO THE PITFALLS OF IDENTIFYING PRICE DISCRIMINATION

This paper demonstrates that plausible cost-based explanations exist for what are commonly perceived to be cases of price discrimination. We explain such commonly discussed problems as the price spreads of retail gasoline products, the "high" price of dinners at restaurants, the "high" price of popcorn at movie theaters, and the fact that airline ticket prices vary with how long the ticket is purchased before the flight's departure. Our explanations benefit from not relying on consumer ignorance or implicit collusion among numerous sellers.     

THE INCENTIVES FOR RESALE PRICE MAINTENANCE UNDER IMPERFECT INFORMATION

This paper considers both the incentives for and the welfare effects of resale price maintenance (RPM) in retail markets characterized by imperfect consumer information. In markets where point-of-sale information on the product is essential for sales and information on prices is costly, RPM permits manufacturers with some monopoly power to resolve two incentive conflicts with retailers. First, because retailers with price-setting powers do not appropriate the gains in profit to an upstream manufacturer from actions taken to increase demand, their incentives to inform consumers of the product and to set low prices are inadequate. This purely vertical externality results in the classic "double mark-up" of final prices. Second, when consumers' costs of price search vary, stores offering low prices and no information can exist in the market equilibrium. These discount houses free-ride on the informational services of high-price informing retail outlets — a horizontal externality. In the imperfect information setting of this paper, (1) administered pricing improves monopolists' profits by resolving the incentive conflict; (2) the profitable use of a price floor reduces the maximum retail price charged and may reduce the average retail price; (3) price floors or administered prices can be Pareto-improving and more likely welfare (surplus)-improving; (4) price floors are welfare-improving.     

HEDONIC PRICE FUNCTIONS

Three feasible interpretations of cross-sectional hedonic price regression equations are derived from consumer choice, profit maximization by competitive firms, and market clearing, each conceptual experiment deploying a Lancastrian "new approach" to micro theory. Lancaster's theory is compared with those consumer theories of Houthakker heritage, and some limitations of each are indicated. The assertion that Adelman and Griliches' quality-adjusted hedonic price index is a constant satisfaction index is shown to necessitate interpersonal comparisons of utility, and the possibility of identifying demand and supply functions for commodities by exclusion restrictions on characteristics is rejected.     

THE EFFECTS OF STATE AUTOMOBILE DEALER ENTRY REGULATION ON NEW CAR PRICES

This paper examines the impact of state regulations restricting entry into new car retailing. The central hypothesis is that these regulations create artificial scarcity rents for existing dealers, which are collected through higher car prices. A reduced form multiple regression model is specified with retail price as the dependent variable. The model is estimated using transactions price data for a sample of over 5,000 Chevrolet dealers and seven car lines in 1978. The results confirm the hypothesis that entry restrictions cause higher car prices.     

ASYMMETRIC ADJUSTMENTS OF PRICE AND OUTPUT

Classical theories predict rapid price adjustments, which are observed in inflationary episodes; Keynesian theories of sticky prices predict sluggish price responses, which are observed in contractions. We attempt to reconcile these observations in a model with asymmetries in producer price and output adjustments. Analysis of SIC two-digit industry data indicates production frequently exhibits negative asymmetry-shortfalls from trend are larger than positive deviations-whereas price often displays positive avmmetry. Evidence supporting two rational motives for asymmetric pricing is presented, but causal interactions between output and price asymmetries are not resolved. (JEL E3)     

SPATIAL COMPETITION AND THE PRICE OF COLLEGE

This article provides the first evidence that universities compete directly on price, and that the market for students depends on the proximity of competitors. Exploiting detailed data from private U.S. universities, price competition is tested by introducing geographic proximity into a spatial-autoregressive tuition model. Standard spatial models show that list and net tuition are inversely related to distance between institutions, consistent with price competition in higher education. An extension to the spatial-econometrics literature relaxes a constraint that estimated spatial relationships are common across all observations, implying that spatial effects differ across qualitative classes of institutions .

STOCK PRICE EFFECTS OF PERMANENT AND TRANSITORY SHOCKS

This paper exploits the long-run equilibrium relationship between stock prices and dividends, implied by the present value model, to structurally identify a dynamic model that governs the behavior of stock prices. The innovations to the data are dichotomized into those that leave a permanent imprint on both series and those that have only transitory effects. Unlike previous studies, however, we do not impose arbitrary identifying restrictions to decompose the joint process, restrictions that may not be consistent the data. ( JEL C12, C32, E24)     

AGGREGATION AND THE STAGGERING OF PRICE CHANGES

Temporal distribution of individual price changes is of crucial importance for business cycle theory and for the microfoundations of price adjustment. While it is routinely assumed that price changes are staggered over time, both theory and evidence are ambiguous. We use a large Belgian data set to analyze whether price changes are staggered or synchronized. We find that the more aggregated are the data, the closer is the distribution to perfect staggering. The results hold both for aggregation across products, and across locations. They are consistent with an economy in which idiosyncratic shocks are the main cause of price changes. (JEL E30, E31, D40)     

DURABILITY, MAINTENANCE AND THE PRICE OF USED ASSETS

This paper considers assets whose service flow decays at a rate determined by built-in durability and the level of maintenance. A cost minimization model determines optimal durability and maintenance and shows how these variables respond to changes in interest rates, the price of maintenance, and the cost of new assets. The price of old assets adjusts so that the cost of services from both old and new assets is the same. The model provides a framework for analyzing data on automobile scrapping rates and repair expenditures. Data for postwar United States show that scrapping rates are sensitive to the price of repairs relative to the price of new cars. The amount of repairs per car also responds to the relative repair price .     

THE OPTIMALITY OF PARTIAL PRICE ADJUSTMENT POLICIES

This paper studies the optimal price adjustment policies of a monopolistically competitive firm whose profit-maximizing price is subject to a serially correlated random disturbance. The firm chooses its price by comparing the expected cost of present and future price changes with the expected losses occurring when price deviates from its instantaneous profit-maximizing value. Partial price adjustment often is the best way to minimize the sum of these losses. Prices tend to be more flexible both in response to large shocks to the firm's profit-maximizing price and when much uncertainty exists about the future.     

FACTOR SUBSTITUTION, RATIONAL EXPECTATIONS, AND THE EFFECTS OF COMMODITY PRICE SHOCKS ON EMPLOYMENT AND INVESTMENT

Within an aggregate model with three inputs to production, the paper studies the effects of an increase in the price of one of the inputs, called commodities. No restrictions are placed on the production possibility constraint, and expectations are assumed to be formed rationally. After considering the effects on the demand for the two remaining inputs, labor and capital, the paper analyzes the effects on employment under a wage rigidity constraint. A dynamic formulation is used to analyze the effects on investment, which are found to depend weakly and sometimes perversely on partial substitution parameters.     

ON THE INFREQUENT ADJUSTMENT OF PRICE BY FIRMS

Many firms change price no more than twice a year. This phenomenon is readily explained by very small price adjustment costs, and the fact that the firm's rate of profit is often insensitive to deviations in the interval between price changes from its optimal level. As a result, firms which change price only once or twice a year may earn almost as much profit as firms that adjust price optimally. This refutes the standard objection that price adjustment costs are too small to matter. The argument does not require extreme assumptions about the flatness of the firm's profit function.     

ASYMMETRIES IN THE RESPONSES OF REGIONAL JOB FLOWS TO OIL PRICE SHOCKS

This paper studies the effect of oil price innovations on manufacturing job flows across U.S. states. First, I estimate a nonlinear structural equation model and compute impulse response functions by Monte Carlo integration. I find asymmetries in the responses of job flows to positive and negative oil price innovations. Yet, these asymmetries do not pass a test of symmetry on the impulse responses, especially after accounting for data mining. Third, I use a test for the absence of job reallocation to evaluate whether an unexpected increase in the real price of oil price triggers an important change in job reallocation. I find that oil price shocks have limited regional allocative effects. (JEL E24, E32, Q43)     

RELATIVE PRICE DISPERSION, AGGREGATE PRICE MOVEMENT, AND THE NATURAL RATE OF UNEMPLOYMENT

This paper develops a model of relative price stickiness and examines its implications for the relationship between relative prices, inflation, and the natural rate of unemployment. Estimation of the model demonstrates that causality in the relationship between relative and aggregate prices runs in both directions. However, microeconomic disturbances have been the primary source of relative price change variance over the postwar period, and these micro disturbances have exerted a strong effect on inflation in the short run. It also is shown that micro relative price change dispersion has had a significant influence on the natural rate of unemployment.     

ON FRUITFUL AND FUTILE TESTS OF THE RELATIONSHIP BETWEEN SEARCH AND PRICE DISPERSION

We exploit cross‐sectional and temporal differences in search intensity in order to examine the relationship between search costs and price dispersion using a hand‐collected panel data set from Jerusalem's Shuk Mahane Yehuda outdoor market. We present empirical evidence that price dispersion increases with the cost of search using several different measures of price dispersion; however, our interpretation of this finding is sensitive to the search proxy in question. We also address several acute difficulties facing empiricists seeking to test theoretical price‐dispersion models in which consumers are heterogeneous in their search behavior. (JEL L11, L13)     

AN EMPIRICAL MODEL OF PRICE AND OUTPUT BEHAVIOR

This paper proposes a model of short-run price and output behavior and undertakes an initial empirical investigation of the model with data from the manufacturing sector of the U.S. Economy. The model provides a relatively precise specification of the various factors that influence prices and output, and joint maximum likelihood techniques are used to estimate the parameters of the model. The empirical results support the proposition that demand-oriented forces primarily influence output while cost-push forces primarily influence prices and indicate that real interest rates affect both prices and output.     

REPUTATION,PRICE, AND DEATH: AN EMPIRICAL ANALYSIS OF ART PRICE FORMATION

We analyze how an artist's death influences the market prices of her works of art. Death has two opposing effects on art prices. By irrevocably restricting the artist's oeuvre, prices, ceteris paribus, increase when the artist dies. On the other hand, an untimely death may well frustrate the collectors' hopes of owning artwork that will, as the artist's career progresses, become generally known and appreciated. By frustrating expected future name recognition, death impacts negatively on art prices. In conjunction, these two channels of influence give rise to a hump‐shaped relationship between age at death and death‐induced price changes. Using transactions from fine art auctions, we show that the empirically identified death effects indeed conform to our theoretical predictions. We derive our results from hedonic art price regressions, making use of a dataset which exceeds the sample size of traditional studies in cultural economics by an order of magnitude. (JEL Z11, J24, G12)     

OPTIMAL PRICE OF ENTRY INTO A COMPETITION

A continuum of contestants are choosing whether to enter a competition. Each contestant has a type, and of those who enter, the ones with highest types receive prizes. A profit‐maximizing firm controls entry, and charges a price for it. I show that an increase in the value of each prize leads the firm to raise the price while keeping the intensity of entry fixed. Conversely, when the mass of prizes increases, the firm initially keeps the price constant while allowing entry to increase; and later—raises the price. (JEL C72, D82, D83)     

DYNAMICS OF RETAIL ADVERTISING: EVIDENCE FROM A FIELD EXPERIMENT

We use a controlled field experiment to investigate the dynamic effects of retail advertising. The experimental design overcomes limitations hindering previous investigations of this issue. Our study uncovers dynamic advertising effects that have not been considered in previous literature. We find that current advertising does affect future sales, but surprisingly, the effect is not always positive; for the firm's best customers, the long-run outcome may be negative. This finding reflects two competing effects: brand switching and intertemporal substitution. We also find evidence of cross-channel substitution, with the firm's best customers switching demand to the ordering channel that corresponds to the advertising. ( JEL L2, L81, M3)     

STOCHASTIC INFLATION AND THE OPTIMAL POLICY OF PRICE ADJUSTMENT

This paper analyzes the optimal policy of price adjustment for a monopolistic firm in the presence of stochastic inflation. It shows that an increase in the expected rate of inflation or in the cost of price adjustment leads to an increase in the initial real price and a decrease in the terminal real price in each period with a fixed nominal price. It also shows that the effects of increased riskiness of inflation are ambiguous.
