The Differential Impact of Accurate Product Cost Information in Imperfectly Competitive Markets: A Theoretical and Empirical Investigation*

Many researchers claim that costing systems that provide materially more accurate or precise cost reports have a strict value-enhancing effect on decisions (i.e., Cooper 1988, 1995; Cooper and Kaplan 1991; Christensen and Sharp 1994; Rogers. Comstock. and Pritz 1994; Swenson 1995; Gupta and King 1997). However, this study provides theoretical and empirical evidence that the value of more accurate cost information may be dependent upon the firm's competitive market structure, as well as the firm's product market strategy. We extend the theoretical work of Gal-Or 1986 to incorporate an endogenous imprecise cost signal in two imperfect market structures: Cournot competition and Bertrand competition with imperfectly substitutable products. In addition, we theoretically link market structure to product market strategy. To examine product market strategy, we employ a laboratory markets design that allows for strategic reaction by a rival firm in each of these markets, because the competitive position of a firm is determined by its capacity to produce at low cost, or to differentiate its product from other products (Porter 1985). Consistent with our theoretical work, we argue that firms that compete on the basis of cost leadership (which we demonstrate may be characterized as Cournot competition), benefit through increased profits from increased product cost accuracy, whereas firms that compete on the basis of product differentiation (which we demonstrate may be characterized as Benrand competition) do not benefit from such increased product cost accuracy. Our results are consistent with this contention. That is, profit is higher in the experimental cost leadership markets (operationalized as Cournot markets) when subjects know their true cost, while profit is higher in the experimental product differentiation markets (operationalized as Bertrand markets) when subjects receive uninformative cost reports and make their decisions based on expected costs. These results suggest that the value of more accurate cost reports may be dependent upon the firm's competitive market structure strategy and product market strategy.     

The Effect of Competitive Bidding on Engagement Planning and Pricing*

This paper investigates how clients' choices regarding whether or not to engage in competitive bidding affect a bidding firm's decisions about planned engagement effort and pricing. Specifically, we investigate whether competitive bidding is associated with higher planned engagement effort and lower fees relative to noncompetitive bidding, and whether competitive bidding is associated with increased sensitivity of effort and fees to cost drivers and the components of service production. There is little available evidence regarding the effects of competitive versus noncompetitive bidding in the current market, and none that focuses on both quality and pricing effects associated with competitive bidding across a broad array of clients. We address these issues using data from a sample of one firm's evaluations of prospective clients, made during 1997‐98. During that period, about half of the firm's bids were competitive and half were noncompetitive, providing a unique opportunity to study how the bidding environment affects engagement planning and pricing. Our findings reveal that competitive bidding is associated with higher planned engagement effort and lower fees. In addition, we find that in competitive bidding situations there are stronger associations between cost drivers and planned engagement effort, and between the components of service production and fees.     

我国出口汇率传递的非对称性:来自中日贸易的证据

文章扩展了Yang（2007）的厂商定价模型，对汇率传递非对称性、特点和成立条件进行理论分析，发现对称传递需要满足严格的条件，而现实中更常见的是非对称汇率传递。在一定条件下，商品需求弹性越大，越可能呈现出口国货币贬值传递率高而升值传递率低的特点。利用2000年1月至2011年12月我国出口日本的966种商品价格数据，发现汇率波动向价格传递具有非对称性：（1）人民币升值时，日元价格上涨较少；而贬值时，价格下降较多。我国出口商品的需求弹性较大，在日本市场上面对的是一个强竞争结构。（2）若月度升值超过一定幅度（测算约为2.43%），传递率又会有所上升，说明尽管日元价格易跌难涨，但在升值导致成本上涨较多、明显挤压利润时，厂商不得不适当提高日元售价。采用2000年至2018年9月日本从中国进口单位价值指数进行稳健性检验，得出类似结论。现阶段稳定的人民币名义汇率对我国出口企业是更为有利的。

Competitive blind spots and the cyclicality of investment: Experimental evidence

We report laboratory experiments investigating the cyclicality of profit-enhancing investment in a competitive environment. In our setting, optimal investment is counter-cyclical when investment costs fall following market downturns. However, we do not observe counter-cyclical investment. Instead, we see much less strategic behavior than our rational investment model anticipates. Our participants exhibit what Porter (1980) terms a competitive blind spot, and heuristic investment models where individuals invest a fixed percentage of their liquidity, or a fixed percentage of anticipated market demand, better fit our data than does optimal investment. We also report a control treatment without cost changes and a treatment with asymmetric investment liquidity. Both of these extensions support our main result.     

A Multiperiod Model and Experimental Evidence of Independence and “Lowballing”*

Abstract. Auditors, regulators, and academics are interested in the pricing practice of “lowballing” and its relationship to auditor independence. Several analytical models have examined these issues. However, these theories have gone untested primarily due to a lack of field data concerning important environmental variables. In this study, a multiperiod model of lowballing and independence is developed and tested in laboratory markets via the experimental economics methodology. The study contributes to the literature in two respects. First, it represents one of the first studies providing empirical evidence and theory testing of the relationship between lowballing and independence. Second, the model presents a new rationale for low-ball pricing and its relationship to auditor independence. Lowballing and impairment of independence, occurring without exogenous transaction costs, are caused by positing cross-sectional variation in audit cost and quality and an informational advantage that accrues to an incumbent auditor-client pair regarding future variation in these audit dimensions. The model is operationalized in a multiperiod laboratory market consisting of multiple sellers and buyers. Sixteen markets are conducted to test price and reporting predictions of the model. The markets strongly exhibit lowballing behavior, but the exact price predictions are generally not supported. The markets also support reporting predictions, with sellers deviating from truthful reporting (impairing their independence) only when additional future profits are greater than the additional cost of misreporting.

Commodity option pricing efficiency before Black,Scholes, and Merton

It is often thought that the arrival of the Black–Scholes–Merton (BSM) model of option pricing in the early 1970s allowed traders to understand how to price and value options with greater precision. However, our study suggests that interwar commodity options traders may have been able to intuit ‘fair’ value and to adjust their prices to changes in the market environment well before the advent of this innovative model. A scarcity of historical price data has limited empirical tests of option price efficiency well before BSM to studies of stock options in the 1870s and the early twentieth century which revealed contrasting findings. This study deals with option pricing in a different market—commodities—during the interwar period. We conclude that option prices were closer to their BSM theoretical values than prior studies suggest. Institutional differences between interwar commodity options markets and stock options markets in the 1870s and the early twentieth century may partly account for this result. Furthermore, we find that interwar option prices were no more mispriced than in modern times, and were as sensitive to changes in volatility—the key valuation parameter in the BSM model.     

PRICE‐SETTING BEHAVIOR IN TURKISH INDUSTRIES: EVIDENCE FROM SURVEY DATA

This study investigates the price‐setting behavior of Turkish industries based on the results of a survey that was conducted by the Central Bank of the Republic of Turkey. The results show that, under normal conditions, the majority of the firms follow a time‐dependent pricing rule but when significant events occur a substantial fraction of them alter their behavior to state‐dependent reviewing. The median Turkish firm reviews its prices every month, but changes its prices four times a year. Price reviews and changes are affected by: the market share, price discrimination, customer type, firm size, and the existence of regulated prices.

Relating Product Prices to Long‐Run Marginal Cost: Evidence from Solar Photovoltaic Modules

A basic tenet of microeconomics is that for a competitive industry in equilibrium the market price of a product will be equal to its marginal cost. This paper develops a model framework and a corresponding empirical inference procedure for estimating long‐run marginal cost in industries where production costs decline over time. In the context of the solar photovoltaic (PV) module industry, we rely primarily on firm‐level financial accounting data to estimate the long‐run marginal cost of PV modules for the years 2008–2013. During those years, the industry experienced both unprecedented price declines and significant expansions of manufacturing capacity. We compare the trajectory of average sales prices with the estimated long‐run marginal costs in order to quantify the extent to which actual price declines were attributable to reductions in production costs. The trajectory of estimated product costs is then extrapolated to forecast an equilibrium trend line for future PV module prices.

Price competition under universal service obligations

In industries like telecom, postal services or energy provision, universal service obligations (uniform price and universal coverage) are often imposed on one market participant. Universal service obligations are likely to alter firms' strategic behavior in such competitive markets. In the present paper, we show that, depending on the entrant's market coverage and the degree of product differentiation, the Nash equilibrium in prices involves either pure or mixed strategies. We show that the pure strategy market sharing equilibrium, as identified by Valletti, Hoernig, and Barros (2002), defines a lower bound on the level of equilibrium prices.     

Examining the impact of home purchase restrictions on China's housing market

This paper studies the impact of home purchase restrictions on China's housing market. We estimate a structural model of household preference for housing, real estate developers' pricing decisions, and equilibrium market outcome in five large cities. By comparing the estimation results from pre- and post-policy intervention, we find that, after home purchase restrictions are implemented, overall housing demand in most cities becomes weaker and less price elastic; meanwhile, real estate developers face higher holding costs and thus are willing to lower prices and sell more quickly. Counterfactual analyses show that in some cities alternative policy designs that cause less structural change of demand could achieve larger consumer welfare and social welfare than the implemented policy.     

The Impact of Korea's Exchange Rate Volatility on Korean Trade

This study uses a GARCH-in-mean model to analyse the impact of Korea's nominal exchange rate volatility on exports and export prices over the current flexible-rate period. The volatility of Korea's won increases the exchange risk of exporters and leads to changes in export volume and price. This paper provides some evidence that nominal exchange rate volatility has had a statistically significant impact on real exports over the current floating-rate period. We show that persistence-in-variance of exchange rates affects the market for exports in Korea. An important result is that the effect of exchange rate volatility on trade variables is shown to be significant. We find that the GARCH conditional variance has a statistically significant impact on the reduced form equations. The magnitude of the effect is generally stronger for export quantities than prices. This result is contradicts that of Kroner and Lastrapes's analysis. This is explained by the fact that Korean exporters choose the strategy of pricing to maintain market share instead of adjusting export prices to reflect exchange rate changes, even when this cuts profit margins.

Housing Supply,Demand and Price: Construction Cost,Rental Price and House Price Indices

Housing prices are subject to the impacts of supply as well as demand. While supply is affected by construction costs, demand is determined by the renting/buying considerations of the public. As a result, the construction cost index (CCI) on the supply side and the rental price index (RPI) on the demand side should be closely related to the house price index (HPI). The present study adopts three price indices of the Taiwan housing market, the CCI, the RPI and the HPI, and examines long‐term and short‐term correlations among the three indices. Empirical results indicate that the relationships among three indices are nonlinear. More interestingly, this article finds that the HPI stimulates changes in the CCI and the RPI, although construction costs and rent are viewed as fundamentals in the existing literature. This phenomenon is rather obvious when deviations of the latter two indices from the HPI are greater. The corrective behavior of the HPI is more notable under these circumstances.     

The Response of Trade Prices to Exchange Rate Changes

The present paper examines export and import pricing behavior following exchange rate changes in small, open economies. Using a monopolistic model, this study reveals that export and import prices should change but not in proportion to exchange rate movements. The policy implication of the results is that the pricing to market phenomenon could be a critical factor in explaining the evolution of the external trade balance with strategic interaction present in the case of prices on tradable goods. Consequently, the use of an exchange rate policy in the case of external imbalances should be a central issue within the broader context of how market structure and conduct affect the optimal traded goods prices.     

An Experimental Investigation of the Effect of Cost Information and Feedback on Product Cost Decisions*

Abstract. In this paper we report the results of an experiment designed to investigate the potential benefits of more accurate costing systems. Subjects in our experiment participated in one of four single-person decision making settings, which varied in terms of the accuracy of costing systems (less accurate versus more accurate cost reports) and in the complexity of the economic environment (less heterogeneous versus more heterogeneous products). The costing systems provided imperfect reports that subjects could use to select forecasts of future product costs. Forecast accuracy determined the resulting payoffs for subjects. In addition to having the cost reports when making forecasts, subjects also observed the association between forecasts and actual profits for previous periods and the rank ordering of the products' relative usage of resources at each of the production processes. The results from our experiment indicate that subjects did not select forecasts based only on reported costs. Rather they updated forecasts using profit feedback and the supplemental rank information about the products' relative usage of resources. We found that profits decreased as the complexity of economic environment increased but increased with the accuracy of cost reports. The profits associated with less accurate costing systems, however, were not as low as we would have predicted had the subjects used the cost reports as their forecasts. In fact, using profit feedback, subjects were able to converge toward optimal profits even with imperfect cost information.     

Does Organizational Form Impact Pricing Asymmetry? Evidence from Nonprofit Financial Institutions

Why output prices tend to rise faster in response to input cost increases than they fall in response to input cost decreases is a hotly debated issue in modern economics. In this article, I contribute to this asymmetric pricing debate by expanding the domain of organizational forms where this question has been investigated. More specifically, previous research has focused on for‐profit firms. I expand the investigation by focusing on nonprofit organizations. Credit unions are the nonprofit organization used in my analysis. Credit unions provide essentially identical types of consumer financial services and products as commercial banks but do so from a very different not‐for‐profit orientation. However, in this study, I document similar asymmetric rate‐setting behavior by credit unions. This suggests that pricing asymmetry is likely to be much more widespread, as it relates to nonprofit institutions as well as those in the for‐profit sector.     

Illegal Cartel Overcharges in Markets with a Legal Cartel History: Bitumen Prices in South Africa

In recent years, South African competition authorities have initiated a number of price‐fixing cases in markets where cooperation among competitors was legal and often encouraged. These markets present economists with special difficulties when estimating cartel overcharges. Conventional approaches often rely on temporal approaches, where pricing during the cartel period is compared with prices in a competitive period. In markets with a legal cartel history, a competitive price cannot be identified in the period preceding illegal collusion. Structural change also reduces data, and hence the robustness of temporal models. Spatial approaches, where prices are compared with those in other countries, offer a better alternative. The paper studies the performance of temporal and spatial approaches in estimating overcharge in the context of a bitumen price‐fixing case. The results suggest that, while the bitumen cartel may have responded to cost and demand shocks in a similar way to how players in more competitive markets respond, it was still cushioned by a large monopoly premium: the long‐run level of South African bitumen prices are higher than in comparable competitive markets. The findings have implications for the study of transition dynamics from legal to illegal cartel regimes and for the detection of cartels.
