Resale price maintenance in a model of consumer search

A retail search model of Salop and Stiglitz (1977) is adapted to analyze manufacturer incentives for resale price maintenance. For some retailer cost functions and distributions of consumer search costs, imposition of a minimum price for retailers causes a price distribution to collapse to an intermediate price. Manufacturers may benefit from price floors when sales to high-search-cost consumers that have obtained lower prices increase sufficiently so as to offset decreased sales to other consumers facing higher prices. In contrast to previous work, no free-riding problem with respect to dealer services is necessary for manufacturers to prefer banning discounting of their products.     

Econometric estimation of distance functions and associated measures of productivity and efficiency change

Multi-input multi-output production technologies can be represented using distance functions. Econometric estimation of these functions typically involves factoring out one of the outputs or inputs and estimating the resulting equation using maximum likelihood methods. A problem with this approach is that the outputs or inputs that are not factored out may be correlated with the composite error term. Fernandez et al. (J Econ 98:47–79, 2000) show how to solve this so-called ‘endogeneity problem’ using Bayesian methods. In this paper I use the approach to estimate an output distance function and an associated index of total factor productivity (TFP) change. The TFP index is a new index that satisfies most, if not all, economically-relevant axioms from index number theory. It can also be exhaustively decomposed into a measure of technical change and various measures of efficiency change. I illustrate the methodology using state-level data on U.S. agricultural input and output quantities (no prices are needed). Results are summarized in terms of the characteristics (e.g., means) of estimated probability density functions for measures of TFP change, technical change and efficiency change.     

Residual value forecasting using asymmetric cost functions

Leasing is a popular channel for marketing new cars. However, the pricing of leases is complicated because the leasing rate must embody an expectation of the car’s residual value after contract expiration. This paper develops resale price forecasting models in order to aid pricing decisions. One feature of the leasing business is that different forecast errors entail different costs. The primary objective of this paper is to identify effective ways of addressing cost asymmetry. Specifically, this paper contributes to the literature by (i) consolidating prior work in forecasting on asymmetric functions of the cost of errors; (ii) systematically evaluating previous approaches and comparing them to a new approach; and (iii) demonstrating that forecasting using asymmetric cost of error functions improves the quality of decision support in car leasing. For example, if the costs of overestimating resale prices are twice those of underestimating them, incorporating cost asymmetry into forecast model development reduces costs by about 8%.     

Transfer prices and incentive contracts in vertically-integrated divisionalized companies

This paper studies a divisionalized firm with sequential transfers in which central management wants to motivate two division managers who receive predecision information. Central management can only contract on the observables price, cost and quantity. Starting with the optimal compensation schemes as a benchmark, the paper considers the question whether using transfer prices to substitute for price and cost, respectively, can replicate the optimal solution or not. This is to say, whether using an aggregate measure comes at a loss. The results are dependent on the design constraints (i) single or ‘dual’ transfer prices and (ii) simultaneous design of the reward functions or exogenously given reward functions. Basically, only in the case that central management is restricted to given reward functions, and wants to use the same single transfer price for both divisions, there is a loss relative to the benchmark solution. In the other cases, generally, there is enough latitude to design the available functions to mimic the benchmark. The paper goes on to discuss special cases. First, it finds conditions when purely cost-based transfer prices are optimal, and second, it derives explicit solutions for given linear compensation schemes over divisional book profits.     

会计中的价值与成本问题

文章探讨"价值"与"成本"在财务会计和成本(管理)会计中的性质与功能。在财务会计中,价值通常来自市场,表现为过去的买入市价、当前的买入或脱手(销售)市价,这些价格可以称为历史成本、现行成本和公允价值,并作为财务会计与报表(报告)的计量属性。但成本会计中的成本则意味着产品成本,是由资产和其他资源的价值转化而来,在产品生产过程中,主要的信息是产品成本的分配、归集和积累,这里没有新价值可以确认,除非产品在市场交换。总之,在财务会计中,价值和成本信息表示一个企业的经营、投资和融资能力,而在成本会计中,只有成本信息表现管理层的才能(比如企业有效利用企业资源效率常表现为成本水平的高低)。     

The inconsistency of common scale estimators when output prices are unobserved and endogenous

This paper explores the inconsistency of common scale estimators when output is proxied by deflated sales, based on a common output deflator across firms. The problem arises when firms operate in an imperfectly competitive environment and prices differ between them. In particular, we show that this problem reveals itself as a downward bias in the scale estimates obtained from production function regressions, under a variety of assumptions about the pattern of technology, demand and factor price shocks. The result also holds for scale estimates obtained from cost functions. The analysis is carried one step further by adding a model of product demand. Within this augmented model we examine the probability limit of the scale estimate obtained from an ordinary production function regression. This analysis reveals that the OLS estimate will be biased towards a value below one, and how this bias is affected by the magnitude of the parameters and the amount of variation in the various shocks. We have included an empirical section which illustrates the issues. The empirical analysis presents a tentative approach to solve the problem discussed in the theoretical part of this paper.     

Duality and continuity

This paper fills the one remaining lacuna in (multiple-output) duality theory by provingjoint continuity (in input and output vectors) of cost, benefit, and (input and output) distance functions. Continuity is an important property where measurement error exists, for it provides assurance that small errors of measurement (of quantities or prices) result only in small errors in concepts like minimal cost. We consider continuity not only in prices and quantities, but also in technologies. Continuity in technologies might be more important than continjity in prices or quantities, because production technologies are almost certainly measured (or estimated) with error.     

An econometric approach to estimating support prices and measures of productivity change in public hospitals

In industry sectors where market prices for goods and services are unavailable, it is common to use estimated output and input distance functions to estimate rates of productivity change. It is also possible, but less common, to use estimated distance functions to estimate the normalised support (or efficient) prices of individual inputs and outputs. A problem that arises in the econometric estimation of these functions is that more than one variable in the estimating equation may be endogenous. In such cases, maximum likelihood estimation can lead to biased and inconsistent parameter estimates. To solve the problem, we use linear programming to construct a quantity index. The distance function is then written in the form of a conventional stochastic frontier model where the explanatory variables are unambiguously exogenous. We use this approach to estimate productivity indexes, measures of environmental change, levels of efficiency, and support prices for a sample of Australian public hospitals.     

Causality and volatility patterns between gold prices and exchange rates

This paper provides a new perspective on the link between gold prices and exchange rates. Based on gold prices denominated in five different currencies and the related bilateral exchange rates, we put causalities and short-run volatility transmission under closer scrutiny. We provide evidence that the identification of a strong hedge function of gold requires an explicit modeling of the volatility component. For all currencies, exchange rate depreciations initially have a negative impact on the gold price after one day which turns out to be positive after two days in most of the cases. Contrary to previous studies, our results point to a specific role of the dollar in the context of gold-exchange rate relationships: volatility of dollar exchange rates more frequently results in strong hedging functions of gold prices. Furthermore, the gold price denominated in the US dollar tends to increase after a depreciation of the dollar.     

Achieving the first best in sequencing problems

Abstract. In a sequencing problem with linear time cost, Suijs (1996) proved that it is possible to achieve first best. By first best we mean that one can find mechanisms that satisfy efficiency of decision, dominant strategy incentive compatibility and budget balancedness. In this paper we show that among a more general and natural class of sequencing problems, sequencing problems with linear cost is the only class for which first best can be achieved.

Estimating the commuting cost and commuting time property price gradients

In this paper, we estimate the property price gradients in Hong Kong. We distinguish our effort from previous studies on the subject by directly measuring the economic distance, i.e., the monetary commuting cost and commuting time, instead of merely the physical distance. Our results are generally supportive of the prediction of a negative property price gradient. In one specification, the estimated capitalization of the savings of commuting cost in property prices appears to be just right. The expected negative effect of commuting time on property values, however, can only be detected among observations with larger commuting times. Nevertheless, over the range where the effect of commuting time has the expected negative sign, the values of time implied by the estimates agree well with the results reported in the transportation economics literature.     

Asymmetric Price Adjustment and Consumer Search: An Examination of the Retail Gasoline Market

This article proposes a new explanation for why retail prices respond more quickly to cost increases than cost decreases. I develop a search model that assumes consumers’ expectations of prices are based on prices observed during previous purchases. This model predicts that consumers search less when prices are falling, which results in higher profit margins and a slower price response to cost changes. I then empirically examine patterns of retail gasoline price response and price dispersion to show that this model predicts observed price behavior better than previously suggested explanations.

Prices and factor demand in an endogenized input–output model

This paper combines factor demand functions (for intermediate input and labour) and price equations (derived from a Generalized Leontief cost function) with the traditional input–output price model. The cost functions determine factor demands for materials and labour as well as output prices at given input prices. At the second level of aggregation, the intermediate demand as a single input is split proportional to the elements in the column of the technical coefficients matrix. The emphasis in this endogenization of technical coefficients is on two features. First, the repercussion of output on input prices, and, second, the link between the econometric model for the supply side and the input–output demand model.     

网络经济下锁定效应的经济学本质及成因研究——基于非转移成本的视角

锁定效应在人类的社会经济生活中是广泛存在的,是影响人类生产、生活决策的基本规律之一。锁定现象是指行为主体当前的决策选择受制于前期的决策行为。以往对于锁定效应成因的分析大多基于转移成本,本文则认为仅仅将锁定效应归结为转移成本是不全面的。本文基于收益和机会成本的角度对锁定效应的经济学本质进行了阐述,并在此基础上,探讨了锁定效应的成因,旨在对锁定效应的理解及其在网络经济下的应用提供借鉴。     

“店选网购”的竞争效应及其反垄断政策涵义

随着互联网和电子商务的发展，消费者在店商试选后以较低价格从网商购买商品的“店选网购”现象非常普遍，厂商或店商经常以其存在搭便车问题为由采取维持转售价格予以限制。本文通过构建具有横向差异化的霍特林模型，考察“店选网购”的竞争效应。研究表明，尽管“店选网购”存在搭便车问题，却能促进店商与网商间的竞争，降低店商和网商的价格和利润，使消费者从中获益，但对社会福利的影响结果是不明确的；其反垄断政策涵义是，“店选网购”具有促进竞争和存在搭便车问题的双重特性，不能简单地作为豁免维持转售价格的正当理由，而应根据实际情况具体分析。     

MARKET POWER AND THE PHARMACEUTICAL INDUSTRY IN SOUTH AFRICA

This paper examines the social cost of the pharmaceutical industry in South Africa. From a regulatory perspective the industry is seen to exhibit monopolylike behaviour resulting in monopoly prices on the supply (manufacturing) side and diminished consumption on the demand (consumer) side. The evidence presented here, which is complementary to that of previous studies, does not support that view. The findings contained here are relevant to the highly contentious subject of access to drugs.     

Endogenous search,price dispersion,and welfare

This paper studies the welfare cost of inflation in a frictional monetary economy with endogenous consumer search. Equilibrium entails price dispersion, where sellers compete for buyers by posting prices. We identify three channels through which inflation affects welfare. The real balance channel is the source of welfare loss. Its interaction with the price posting channel generates a welfare cost larger than Lucas (2000). The search channel reduces the welfare cost by more than one half through general equilibrium effect. The aggregate effect of these three channels on welfare is non-monotonic. Additionally, the welfare cost of inflation fluctuations is negligible.     

Mean value theorem for convex functions

Closed proper convex functions have many properties in common with differentiable functions such as continuity and one-sided directional derivatives. In this paper it is shown that there exists a mean value theorem for such functions with the gradient vector in the differentiable case replaced by an element of the subdifferential in the convex case.Under compactness of the isoquant sets, (minus) the cost functions are convex and with the theorem above it is easy to show that under incomplete specialization and constant returns to scale the prices of international goods determine uniquely the prices of domestic goods if the isoquant sets are linearly independent.     

基于New-Cost-DEA模型的污水处理企业成本效率研究

近年来,中国污水处理企业的数量迅速增加,污水处理能力不断提高,但仍存在运行效率低下的问题。本文运用New-Cost-DEA模型,构建污水处理企业运行成本效率模型,测算13座污水处理企业的运行成本效率,并对运行成本进行分解,寻找造成运行成本损失的原因。结果显示:影响污水处理企业成本效率的因素不仅和投入要素数量有关,而且与投入要素价格有关;污水处理企业的成本效率低,是由于价格因素和配置效率引起的,需要通过降低投入要素的价格和对投入要素进行优化组合来降低运行成本,提高运行效率。
