Hedonic prices and cost/benefit analysis

Hedonic prices have been used to evaluate the willingness to pay for attributes. We reformulate the notion of hedonic price from a composite price on housing to a unit price on traded quantities, in conformity with long run competitive equilibrium theory. This formulation was suggested (but not developed) by Rosen (J. Polit. Econ.82, No. 1 (1974), 34–35). By first characterizing an efficient allocation of consumers to space, we show that hedonic unit prices can be understood as a bid-rent function which supports the efficient allocation. This is despite the fact that the lots over which consumers bid are themselves endogenous. We show that unit hedonic prices reveal preferences in a manner different from composite hedonic expenditures.     

Planning under market socialism when iteration is incomplete

If an iterative planning procedure is cut short due to time shortage, the plan must be set subject to information gaps. But the nature of these gaps depends on which iterative procedure was used. For the case of Lange's model, Weitzman's “prices versus quantities” framework is redeveloped for the particular information gaps then found. With one good, the optimal quantity signal comes from the expected supply-demand intersection, but an optimal price signal lies between this intersection and the price from the last stage of iteration. When there are many goods, however, we cannot be so specific.     

Profit Differences and Corporate Power: Some Empirical Surprises

Inflation targeting is currently the policy of choice for central banks. This policy invariably targets consumer price inflation, which is only one of many available price level indices (such as prices of new investments and house prices). As there is no stable relationship between these price levels, and as differences in developments between the different price levels might induce destabilizing behavior, there is no reason why “low and stable” consumer price inflation should guarantee monetary and financial stability. Following John Maynard Keynes, a “low and stable” increase of average nominal wages might do a better job. As price levels are designed to estimate the purchasing power of spending power and as income, and spending power are used to not just consume or invest but also to pay down many kinds of (gross) debt, it is advisable to use a joint definition of monetary and financial stability, which combines stable purchasing power of monetary income with a stable ability of households and companies to pay off debts.     

Deregulated Wholesale Electricity Prices in Italy: An Empirical Analysis

In this paper we analyze a time series of daily average prices in the Italian electricity market, which started to operate as a Pool in April 2004. Our objective is to model the high degree of autocorrelation and the multiple seasonalities in electricity prices. We use periodic time series models with GARCH disturbances and leptokurtic distributions and compare their performance with more classical ARMA-GARCH processes. The within-year seasonal variation is modelled using the low-frequency components of physical quantities, which are very regular throughout the sample. Our results reveal that much of the variability in the price series is explained by the interactions between deterministic multiple seasonalities. Periodic AR-GARCH models seem to perform quite well in mimicking the features of the stochastic part of the price process.

Repeated price competition between individuals and between teams

We conducted an experimental study of price competition in a duopolistic market. The market was operationalized as a repeated game between two “teams” with one, two, or three players in each team. We found that asking (and winning) prices were significantly higher in competition between individuals than in competition between two- or three-person teams. There were no general effects of team size, but prices increased with time when each team member was paid his or her own asking price and decreased when the team's profits were divided equally. This result is consistent with a simple model of individual learning.     

Causality between money and prices in Indonesia

The purpose of this study is to examine the relationship between money supply and prices in Indonesia, where money supply is taken to be the stock of narrow money (currency + demand deposits) and prices are proxied by the Jakarta cost of living index. The period studied is 1969–1980. Two concepts of causality namely “proper” causality in which the causal effect takes at least one quarter to manifest itself and “instantaneous” causality in which there are no lags, are employed. The hypothesis of “proper” causality is rejected by bothGranger andSims tests. However, the hypothesis that money and prices are contemporaneously correlated cannot be easily dismissed. Using the framework of [Geweke], contemporaneous causality is treated as a part of linear feedback and the lagged version of Sims test was used. We found that the hypothesis that prices cause money supply cannot be dismissed on the basis of Wald test. However, the contribution of instantaneous causality is very large to the total variance of linear feedback.     

Price Level Determinacy under a Pure Interest Rate Peg

In this article we reexamine a famous result by T. J. Sargent and N. Wallace (1975, Journal of Political Economy83, 241–254) according to which a “pure interest rate peg” leads to nominal price indeterminacy. We use P. Weil's (1991, International Economic Review32, 37–53) generalization of the Sidrauski–Brock model, where arrival of new “generations” of infinitely lived agents is allowed, and we obtain the following results: (i) Nominal indeterminacy holds in the traditional Sidrauski–Brock framework; (ii) This nominal indeterminacy disappears as soon as new generations arrive in time, via some rigorous version of Patinkin's “real balance effect”; (iii) A multiplicity of solutions may still remain, but full determinacy occurs in some cases, depending notably on fiscal policy or the distribution of endowments in time.

Toward Reasonable Capitalism: The Role of John R. Commons’s Price and Business Cycle Theories

Abstract

John R. Commons thought that prices should be stable and that the law of supply and demand should be controlled by the power of the state through patent law and by protecting bargaining equality. Commons also thought that prices should be stabilized by macro monetary policy. These means would allow the realization of a “reasonable price.” Commons called the objective and measurable value in money, which is determined by a court ruling, “reasonable value.” Analysis of Commons’s price and business cycle theories point toward the realization of both “reasonable price” and “reasonable value” and toward “reasonable capitalism” that can replace banker capitalism.     

Stylised features of consumer price setting behaviour in Portugal: 1992–2001

This paper identifies the empirical stylized features of consumer price setting behavior in Portugal using two micro-datasets underlying the consumer price index. The main conclusions are: one in every four prices change each month; there is a considerable degree of heterogeneity in price setting practices; prices of goods change more often than prices of services; price reductions are common, as they account to around 40% of total price changes; price changes are, in general, sizeable; finally, the price setting patterns seem to depend on the level of inflation as well as on the type of outlet.

Starting Small and Commitment

I study a model of a long-term partnership with two-sided incomplete information. The partners jointly determine the stakes of their relationship and individually decide whether to cooperate with or betray each other over time. I characterize the extremal—interim incentive efficient—equilibria. In these equilibria, the partners generally “start small,” and the level of interaction grows over time. The types of players separate quickly. Further, cooperation between “good” types is viable regardless of how pessimistic the players are about each other initially. The quick nature of separation in an extremal equilibrium contrasts with the outcome selected by a strong renegotiation criterion (as studied in Watson (1999, J. Econ. Theory85, 52–90).

Core allocations and the dimension of the cone of efficiency price vectors

Let (R₁,…,R_k) be an arbitrary partition of the grand coalition in an atomless exchange economy with k “large enough.” We prove that an optimal allocation x belongs to the core if and only if x cannot be improved upon by any coalition that includes at least one of the R_i's. K is “large enough” if k ? r + 1, where r is the linear dimension of the cone P of the efficiency price vectors for x. Recall that it is always true that r ? n, when n is the number of commodities in the market, and that under differentiability and interiority r = 1; thus k can be chosen to be 2 (i.e., for any coalition R, an allocation x belongs to the core of the market if and only if x is not blocked by any coalition that either contains R or contains its complement).     

Asymmetries in price and quantity adjustments by the competitive firm

Focusing on the crucial role of inventory carry-overs in the production and sales decision, we describe the profit maximizing behavior of a dynamic competitive firm facing random prices. Each firm's behavior is incorporated into a stochastic equilibrium model of the competitive industry with uncertain demand. The industry model exhibits asymmetric cyclical fluctuations of the “Keynesian” sort: when demand is weak, output contracts while price holds at a fixed floor; when demand is strong, price increases as output is constrained by a ceiling. Even in a pure world of constant returns, without increasing costs, the inability to instantaneously coordinate production and sales along with the existence of inventories is sufficient to yield a “backward L” shaped supply curve for the short run.     

Reexamination of Strategic Public Policies

This paper attempts to reinterpret the familiar approach to strategic public policies from the viewpoint of inefficiencies involved in oligopoly where firms engage in Cournot competition. To this end, we introduce tools called “quasi‐reaction functions” and “quasi‐supply curves”. These tools allow us to conduct analyses through use of the standard partial‐equilibrium diagram, i.e. the quantity‐price plane. We can find the relationship between prices and quantities directly and, hence, deal with inefficiencies easily and also suggest policies to correct such inefficiencies. Specifically, we reexamine public policies related to mixed‐oligopoly, excess entry, technology choices with free entry and exit, and foreign oligopoly.     

Average-cost pricing: Some evidence and implications

We present new survey evidence on pricing behavior for more than 14,000 European firms, and study its macroeconomic implications. Among firms that are price setters, roughly 75% respond that their prices are set as a markup on total costs, a business practice termed “full cost pricing”. Only 25% set prices as markups over variable or marginal costs. Moreover, using industry data for the U.S., we find that the correlation between changes in output prices and changes in variable input prices is significantly lower when fixed costs are likely to be more important.Since our results are similar to the findings in the classic and controversial paper of Hall and Hitch (1939) and subsequent survey evidence, we believe it worth studying the implications of full cost pricing for macroeconomics. We first propose a problem for the firm where full cost pricing can arise as optimizing behavior. We embed this problem, featuring an occasionally binding constraint, into a simple general equilibrium model. We show that when the model is hit by a shock that makes the constraint binding, the response of endogenous variables is amplified significantly more than it would be under the unconstrained regime.     

Personalized pricing and advertising: An asymmetric equilibrium analysis

We study personalized price competition with costly advertising among n quality-cost differentiated firms. Strategies involve mixing over both prices and whether to advertise. In equilibrium, only the top two firms advertise, earning “Bertrand-like” profits. Welfare losses initially rise then fall with the ad cost, with losses due to excessive advertising and sales by the “wrong” firm. When firms are symmetric, the symmetric equilibrium yields perverse comparative statics and is unstable. Our key results apply when demand is elastic, when ad costs are heterogeneous, and with noise in consumer tastes.     

An econometric analysis of the effects of market liberalization on price dynamics and price volatility

The paper investigates price dynamics under market liberalization, with a focus on the effects of lowering price floors. We analyze price dynamics by specifying and estimating a dynamic Tobit model under time-varying volatility, where the market price is censored by a government-set support price. The model is applied to the U.S. butter market over the last three decades. The econometric results show how the price support program affects both expected prices and the volatility of prices. It is found that the censoring effects of a price support program can be significant and large even if the price support is set relatively low.

Product variety and price strategy in the ski manufacturing industry

The present paper aims at examining the role of variety in the ski manufacturing industry and its relevance in firms’ price setting strategies. In particular, it intends to investigate and to empirically test three hypotheses concerning the relations between: product quality and prices; variety in technical characteristics and prices; variety in service characteristics and prices. Our empirical investigation finds that prices are positively affected by product quality and positively affected by variety in service characteristics. This means that a high degree of product variety allows firms to charge a premium price on consumers, who are able to find the product that best meets their needs and are therefore willing to pay a higher price. By contrast, variety in technical characteristics negatively impacts prices. In a context where a dominant design has emerged and new varieties are not radically different from each other, the gains in economies of scale and scope outweigh the costs of the increased flexibility in the equipment required to produce variety.

How Communication Improves Efficiency in Bargaining Games

We study a double auction with two-sided private information and preplay communication, for which Myerson and Satterthwaite (1983, J. Econ. Theory28, 265–281) showed that all equilibria are inefficient and the Chatterjee–Samuleson linear equilibrium is most efficient. Like several others, we find that players use communication to surpass equilibrium levels of efficiency, especially when the communication is face-to-face. Our main contribution is an analysis of how communication helps the parties achieve such high levels of efficiency. We find that when preplay communication is allowed, efficiency above equilibrium levels is a result of what we call “dyadic” strategies that allow the parties to coordinate on a single price that reflects both parties' valuations.

Modelling financial transaction price movements: a dynamic integer count data model

In this paper we develop a dynamic model for integer counts to capture fundamental properties of financial prices at the transaction level. Our model relies on an autoregressive multinomial component for the direction of the price change and a dynamic count data component for the size of the price changes. Since the model is capable of capturing a wide range of discrete price movements it is particularly suited for financial markets where the trading intensity is moderate or low. We present the model at work by applying it to transaction data of two shares traded at the NYSE traded over a period of one trading month. We show that the model is well suited to test some theoretical implications of the market microstructure theory on the relationship between price movements and other marks of the trading process. Based on density forecast methods modified for the case of discrete random variables we show that our model is capable to explain large parts of the observed distribution of price changes at the transaction level.

DIRECTED SEARCH,COORDINATION FAILURE,AND SELLER PROFITS: AN EXPERIMENTAL COMPARISON OF POSTED PRICING WITH SINGLE AND MULTIPLE PRICES

We experimentally examine posted pricing and directed search. In one treatment, capacity‐constrained sellers post fixed prices, which buyers observe before choosing whom to visit. In the other, firms post both “single‐buyer” (applied when one buyer visits) and “multibuyer” (when multiple buyers visit) prices. We find, based on a 2 × 2 (two buyers and two sellers) market and a follow‐up experiment with 3 and 2 × 3 markets, that multibuyer prices can be lower than single‐buyer prices or prices in the one‐price treatment. Also, allowing the multibuyer price does not affect seller profits and increases market frictions.
