Competition and Service Quality in the U.S. Airline Industry

The U.S. government, media, and flying public have expressedgreat concern in recent years over both airline market concentration and flightdelays. This study explores potential connections between the two by examining whetherthe lack of competition on a particular route results in worse on-time performance.Analysis of data from the U.S. Bureau of Transportation Statistics in 2000 indicatesthat both the prevalence and duration of flight delays are significantly greater onroutes where only one airline provides direct service. Additional competition iscorrelated with better on-time performance. Weather, congestion, and schedulingdecisions also contribute significantly to explaining flight delays.     

Industry Structure,Segmentation, and Quality Competition in the U.S. Hotel Industry*

We examine how quality competition affects the relationship between market size and industry structure at the product level using evidence from the U.S. hotel industry. Starting in the early 1980s, quality competition for business travelers became more based on variable and less on fixed costs, and became less scale intensive. Since then, market size increases have been met by more, but smaller, hotels in business travel destinations but continued to be met by larger hotels in personal travel destinations. Our results illustrate how the way consumers benefit from increases in market size depends on how firms compete.     

On the Price Comovement of U.S. Residential Real Estate Markets

We investigate the comovement among Case‐Shiller Home Price Indices for 14 metropolitan areas between 1992 and 2008. We define the portion of this comovement deemed as fundamental (excessive) as the covariation that can (cannot) be attributed to common fundamental factors directly influencing real estate prices. We find that i) comovement among these markets considerably increased over the sample period, especially in the late 1990s; ii) this increase is mostly attributable to underlying systematic real and financial factors, consistent with a greater fundamental integration of those markets; and iii) excess comovement is a less important factor than commonly believed. We discuss the implications of these results for the evolution of U.S. real estate prices over the last two decades and the ongoing credit crisis.     

Price Dispersion Over the Business Cycle: Evidence from the Airline Industry

This study provides empirical evidence documenting how price dispersion moves with the business cycle in the airline industry. Performing a fixed‐effects panel analysis on seventeen years of data covering two business cycles, we find that price dispersion is highly pro‐cyclical. This effect is especially pronounced for legacy carriers relative to low‐cost carriers. We show that our empirical result is consistent with firms' implementing second‐degree price‐discrimination tactics.     

Quantifying the Effects of Price Discrimination Under Imperfect Competition*

This article analyzes the effects of broadband carriers switching from price discrimination to uniform pricing. Broadband carriers often use third-degree price discrimination. In Colombia, broadband carriers rely on government-issued socio-economic information to segment markets. I use demand and marginal cost estimates to quantify the effects of switching from price discrimination to uniform pricing in an environment of high income disparity. The results provide direct evidence of large consumer surplus transfers from poorer to wealthier households. Poorer households respond by subscribing to slower Internet plans, which may undermine prior efforts to increase download speeds in this demographic.     

Price transmission across the U.S. food distribution system

Price transmission models are estimated using recursive methods across 100 food commodities. From the individual commodities, short- and long-run price transmission coefficients are estimated for rising and falling prices. These coefficients are classified into five commodity categories and expressed as one vector while coding for causality, market levels, rising/falling prices, short and long run, and time period. Then the impact of each variable is estimated and inferences are drawn about the degree of price transmission. Results show that price linkages are strong but slightly declining over time, with some evidence of asymmetric behavior. Long-run rising prices are passed through more than long-run falling prices, except for fruits and vegetables.     

Third-Degree Price Discrimination in Oligopoly when Markets are Covered*

We analyze oligopolistic third-degree price discrimination relative to uniform pricing when markets are covered. Pricing equilibria are critically determined by supply-side features such as the number of firms and their marginal cost differences. It follows that each firm's Lerner index under uniform pricing is equal to the weighted harmonic mean of the firm's relative margins under discriminatory pricing. Uniform pricing then lowers average prices and raises consumer surplus. We can calculate the gain in consumer surplus and loss in firms' profits from uniform pricing based only on the market data of the discriminatory equilibrium (i.e., prices and quantities).     

PRICE COMPETITION IN U.S. BREWING*

This study utilizes a brand‐level dataset that captures a unique natural experiment, a 100% increase in the excise tax, to evaluate different pricing models in the U.S. beer industry. To assess the plausibility of different models, the increase in marginal cost resulting from the tax increase is exploited: observed prices in the post‐increase period are compared to the prices that should be observed under various pricing models. Three types of models are analyzed: Bertrand‐Nash, leadership, and collusion. Results indicate that extreme cases of collusion can be confidently ruled out while several models may explain the observed prices equally well.     

The Cyclic Behavior of the U.S. Lodging Industry

A recently constructed data series suggests that the hotel industry has experienced two rather large building booms from 1969 to 1994. By contrast, hotel demand seems to move closely with the United States economy, at a much higher cyclic frequency. Occupancy and room rental rates follow the slower movements in supply. A structural model is estimated over this series which displays long lags between occupancy and room rental rate changes, as well as between room rental rates and new supply. These lags create a system of difference equations that is close to being dynamically unstable. Forecasting forward with smooth economic growth, yields a new and even larger future building boom.     

美国纺织工业的兼并浪潮

1998年是美国纺织工业企业兼并重组活动创纪录的一年,并且兼并的步伐似乎不会停止。面对强大的竞争压力,越来越多的公司选择合并或购并其它公司以努力改善其命运。本文透过1998年企业兼并活动,探讨推动     

Competition and Price Discrimination: Evidence from the Parking Garage Industry

We study the relationship between competition and price discrimination through an empirical examination of hourly price schedules in the parking garage industry. We find that the degree of price schedule curvature decreases with competition, implying a greater proportionate drop in low‐end prices than in high‐end prices when competition intensifies. Our findings suggest that competition constrains a firm's capacity to exercise price discrimination, confirming the classic textbook theory. We also offer possible explanations for our findings, including a search cost explanation, for which we find some support in the data.     

Price Effects of Across-State Regulation of U.S. Electric Utilities

Investor-owned utilities (IOUs)serving multiple states are subject to multiple publicservice (utility) commission (PSC) regulation. Focusing on relative rates of an IOU across PSCsisolates regulatory effects. This analysis examines38 such multistate IOUs from 1995. For theresidential-commercial customer comparison, electedPSC commissioners, Republican-appointed commissioners,PSC jurisdiction over municipally-owned utilities (anindirect IOU competitor), and IOU home-state statusare associated with a higher relative rate, whereasmore PSC employees per capita and population densityare associated with a lower relative rate. Thecommercial-industrial comparison results are largelyreversed, but are similarly robust.     

Linking Product Development Outcomes to Market Valuation of the Firm: The Case of the U.S. Pharmaceutical Industry*

The purpose of this research was to examine empirically the effects of new product development outcomes on overall firm performance. To do so, first product development and finance literature were connected to develop three testable hypotheses. Next, an event study was conducted in order to explore whether the changes in the stock market valuation of firms are influenced by the outcomes of efforts to develop new products. The pharmaceutical industry was chosen as the empirical context for the present study's analysis largely because the gate‐keeping role played by the Food and Drug Administration (FDA) provides a specific event date on which to focus the event study methodology. As such, this study's events were dates of public announcements of the FDA decisions to approve or to reject the New Drug Applications submitted by the sponsoring firms. Consistent with the efficient market hypothesis, this study's results show that market valuations are responsive strongly and cleanly to the success or failure of new product development efforts. Hence, one of this study's key results suggests that financial markets may be attuned sharply to product development outcomes in publicly traded firms. This study also finds that financial market losses from product development failures were much larger in magnitude than financial market gains from product development successes—indicating an asymmetry in the response of financial markets to the success and failure of new product development efforts. Hence, another implication of this study's results is that managers should factor in a substantial risk premium when considering substantial new development projects. The present study's results also imply that managers should refrain from hyping new products and perhaps even should restrain the enthusiasm that the financial community may build before the product fully is developed. The effect on firm value is severe when expectations about an anticipated new product are not fulfilled. Managers in effect should take care to build reasonable and realistic expectations about potential new products.     

The Welfare Effect of Advertising Restrictions in the U.S. Cigarette Industry

The welfare effect of advertisingrestrictions in the U.S. cigarette industry dependsupon the impact of advertising on consumer and producer surplus, the transfer to consumers for being exposed to utility-reducing advertising, and smoking externalities. We estimate a demand equation and a supply relation simultaneously and use the parameter estimates to generate predictions of the impact of advertising restrictions on social welfare. Our results show that advertising restrictions benefit producers by limiting competition and generating higher industry profits, and such restrictions lower social welfare if the external cost of cigarette smoking is sufficiently low.     

Diffusion and Performance of Modular Production in the U.S. Apparel Industry

This article examines the determinants of the diffusion of team production systems (modular assembly) and the impact of these systems on firm performance relative to traditional assembly systems in the apparel industry. The article draws on an extensive survey providing detailed information on a wide range of manufacturing practices and retail relationships in the U.S. apparel industry. We find that recent diffusion of modular practices is driven primarily by the product market. We also show that modular systems affect business-unit performance (particularly operating profits) where they are combined with complementary investments in information systems linking apparel suppliers with retail customers.
