Sales and Firm Entry: The Case of Wal‐Mart

Temporary price reductions or “sales” have become increasingly important in the evolution of the price level. We present a model of repeated price competition to illustrate how entry causes incumbents to alternate between high and low prices. Using a six‐year panel of weekly observations from a grocery chain, we find that individual stores employ more sales as the distance to Wal‐Mart falls. Moreover, the increase in the frequency of sales was concentrated on the most popular products, suggesting the use of a loss‐leader strategy.     

The Discriminating Beta: Prices and Capacity with Correlated Demands

Uniform customer‐class pricing can do much of the work of congestion‐based or time‐of‐day pricing in communication or wireless networks. A monopolist exploits differences in the stochastic characteristics of demands. If demands are correlated and the firm faces a capacity constraint, then it can set prices to reduce the variability of aggregate demand, thereby reducing the probability of excess demand and the associated service quality deterioration. Demands that covary negatively with aggregate demand are valuable to the firm in much the same way that securities that covary negatively with the market are valuable in a stock portfolio. Customer classes that exhibit low covariance with aggregate demand realize lower optimal prices. Optimal capacity is also affected by these covariances. As long as demands are not perfectly positively correlated, expected costs of joint production are less than expected costs of serving demands separately.     

Green Consumption under Misperceived Prices: An Application to Active Transportation

We propose a consumption model that captures the impact that perceived price ambiguities may have upon decision‐making in green markets in general and in active transportation markets in particular. The basic intuition for the model is that a consumer who may be misperceiving the price of the green good (the active transportation mode) would be willing to pay a positive amount from her income in the current period to resolve the misperception going forward. We posit that the basis for the price misperception in the active transportation context is misperception of the relative risks involved in taking that mode. The compensating variation that aligns perceived and objective risk is derived. We show how raising green consumption via price misperception correction can be superior to traditional economic policy instruments. The results shed light on the more general family of situations in which agents may consistently misperceive aspects of the decision environment.     

Dueling Jackpots: Are Competing Lotto Games Complements or Substitutes?

This paper considers the relationship that exists between two lottery products offered simultaneously in the same state, a smaller lottery game run by the individual state and a larger multi-state game run in coordination with other states. The primary issue is whether the two different products should be considered substitutes or complements for one another. The question is considered from two different perspectives that lead to a conclusion that while the two products do tend to be complements to one another, overall the individually run state lottery games experience a reduction in sales from the presence of the multi-state game.     

Antidumping jumping: Reciprocal antidumping and industrial location

Antidumping Jumping: Reciprocal Antidumping and Industrial Location. — Antidumping policies are often justified as legitimate actions by governments in their efforts to protect domestic producers from unfair foreign competition. The authors investigate the impact of antidumping rules on firms’ production decisions as to how much and where to produce. Antidumping measures may have unforeseen effects if they induce direct foreign investment and consequently increase domestic competition. The authors therefore focus on location choice and consider the strategies of national governments attempting to advance the interests of their citizens through antidumping legislation. The analysis also has implications for the effects of market integration policies, such as Europe 1992.     

Consumer Rationing and Cournot Outcomes: Experimental Evidence

We report the results of duopoly market experiments where firms first commit to capacities and then compete in prices. The theoretical literature pertaining to these duopoly models suggests that the way residual demand is rationed is fundamental to the character of equilibrium outcomes when capacity costs are sufficiently low. The experiments test this prediction by varying capacity cost and demand‐rationing schemes. We find that residual demand rationing does not significantly impact the capacity choices of experimental subjects, although it does affect pricing. Regardless of rationing scheme, the Cournot outcome is common with high capacity costs and rare with low capacity costs.     

Multi‐Market Competition,R&D,and Welfare in Oligopoly

We investigate a multi‐market Cournot model with strategic process research and development (R&D) investments wherein a multi‐market firm meets new competitors that enter one of the markets. We show that entry can enhance the total R&D expenditures of the multi‐market firm. Moreover, the incumbent's profit nonmonotonically changes as the number of entrants increases. Depending on the fixed entry costs and R&D technologies, both insufficient and excess entry can appear. Our results imply that diversification of their products can be a useful strategy for firms.     

How Do Retailers Price Beer During Periods of Peak Demand? Evidence from Game Weeks of the German Bundesliga

This article considers retail beer pricing during game weeks of the German Bundesliga. German consumers exhibit a high degree of brand‐loyalty in their preference for regionally crafted beers, and we exploit the regional brand‐loyalty of German beer consumers to identify brand‐level demand shocks for beers preferred by the home team's fans and visiting team's fans during Bundesliga game weeks. We find retailer price adjustments at the category level mask a considerably more nuanced pricing behavior at the brand level. Retailers in regions hosting Bundesliga games significantly increase beer prices at the category level during game weeks; however, at the brand level, we find retailers selectively discount prices on the home team's sponsored beers and systematically raise prices on the visiting team's sponsored beers. Our findings are consistent with a “tourist–natives” model of retail pricing during periods of increased demand in the German beer market.     

The Persistence of Dominant‐Firm Market Share: Raising Rivals' Cost on the New York Stock Exchange

To explain the persistence of dominant New York Stock Exchange (NYSE) market share in stock trading of listed securities from 1992 to 2002, we develop a dominant‐firm price leadership model and hypothesize that NYSE specialists raised the costs of rival market makers. The model predicts that natural and induced cost advantages will determine the NYSE's market share vis‐à‐vis the regional exchanges, electronic trading systems, and NASDAQ dealers. Empirically, NYSE market share increases with economies of scale and scope, abnormal price volatility, high asymmetric information, and with trading practices that raise rivals' costs, such as failure to display limit orders that bettered the existing quotes.     

Industrial concentration, price-cost margins, and innovation

This paper explores a panel data set matching establishment-based production statistics from Japan's Census of Manufacturers with wholesale price indices from the Bank of Japan, and Herfindahl indices from the Japan Fair Trade Commission. The data include annual observations over the period 1961-1990, for 74 industries at the four-digit s.i.c. level. I estimate Cobb-Douglas production functions and Solow residuals for each industry and then use these estimates to further analyze the determinates of industrial concentration and innovation. The industries having great capital intensity and small employment of labor tend to be more concentrated. Cross-section estimates reveal a U-shaped mapping from concentration to innovation.     

Incumbent Response to Entry by Low‐Cost Carriers in the U.S. Airline Industry

This article studies incumbent price response to entry by low‐cost carriers in the U.S. airline industry. I find that legacy carrier incumbents decrease their mean airfare, 10th percentile airfare, and 90th percentile airfare following entry by a low‐cost carrier. Airfares decrease by a larger percentage at the right tail of the incumbents’ price distribution than at the left tail, suggesting that increased competition from low‐cost carrier entrants leads to lower price dispersion.     

Quality and Quantity Competition in a Multiproduct Duopoly

This article proposes a Cournot model of two‐stage competition to examine the patterns of vertical product differentiation in a multiproduct duopoly. Firms simultaneously choose the number of products and their qualities at the first stage and compete in quantities at the second stage. We show that when the fixed setup cost of a product is high enough to result in a monopoly outcome, the monopolist always sells a single product. Moreover, in any equilibrium of a multiproduct duopoly, quality differentiation between them will develop into a nonsegmented pattern because each firm desires to avoid a strong effect of cannibalization. The set of equilibria reveals the properties of quality differentiation between multiproduct firms. In a multiproduct duopoly, the profit from a high‐quality product can be lower than that from a low‐quality product. This finding sharply contrasts with the literature on single‐product firms, which finds the high‐quality advantage.     

Asymmetric Fluctuating Behavior of China's Housing Prices

The present study explains the reasons for the imbalanced development of the Chinese housing market. Using the quantile autoregression unit‐root test, we examine housing prices in China's five major cities. The results show that the rising and falling of housing prices in these cities exhibits asymmetric reversion. When housing prices fall, market capital is highly sensitive to housing prices, and housing prices resist the pressure to fall further. However, when housing prices rise, the housing market becomes imbalanced, with housing prices tending to overreact in an upturn. The results of this study indicate that when housing prices rise irrationally, the government should intervene in the housing market promptly to prevent housing bubbles.     

Emporiophobia (Fear of Markets): Cooperation or Competition?

Widespread emporiophobia (fear of markets) has important policy implications, since it leads voters to demand anti‐market policies. There are many reasons for this anti‐market attitude; however, economists could reduce emporiophobia if we stressed cooperation rather than competition in writings and policy discussions. In a sample of introductory textbooks, competition is mentioned on average eight times as often as cooperation. The fundamental economic unit is the transaction, and transactions are cooperative. The benefit of a market economy—increased consumer surplus—comes from cooperation through transactions, not from competition. Competition in a market economy is competition for the right to cooperate. Competition is important because it guarantees that the best cooperators will win and because it establishes the efficient terms for cooperation, but cooperation is fundamental. For most people, competition has negative connotations since it focuses on losers, while cooperation implies a win–win situation. Other implications involve the morality of the market, “giving back,” and characteristics of market failures.     

Price Rigidity and Industrial Concentration: Evidence from the Indonesian Food and Beverages Industry

This paper investigates the relationship between industrial concentration and price rigidity in the Indonesian food and beverages industry. A Cournot model of firm behavior is used in which prices adjust according to a partial adjustment mechanism. The model is applied to panel data of the Indonesian food and beverages industry over the period 1995–2006. The results suggest that industrial concentration has a positive effect on percentage price changes. Furthermore, the speed of price adjustment is higher when the per unit cost of production rises.     

Ranking U.S. Economics Programs by Faculty and Graduate Publications: An Update Using 1994–2009 Data

This article ranks academic institutions by pages published in top economics journals over the 1994–2001 and 2002–2009 periods. Because it uses a methodology similar to several earlier articles, this article permits a consideration of how institutions' ranks have changed over the past 35 years. I construct rankings based on publications by individuals affiliated with each institution, by faculty members in the economics departments at each institution, and by alumni of each doctoral program. With few exceptions, the positions of programs near the top of the rankings change little over time. However, much more dramatic changes in rank occur for lower‐ranked institutions.     

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.     

More similar and less equal: Economic growth in the European regions

More Similar and Less Equal: Economic Growth in the European Regions. — This paper examines the growth process of 109 European regions using a new data base. Applying various statistical tools, it concentrates on per capita income and labor productivity. The main results are the following: There has been a clear process of aggregate productivity convergence across the European regions over the 1980s. At the sectoral level, there has not been convergence in agriculture, while the industrial and services sectors show ß-convergence. Most crucially, the regional dispersion in per capita income has remained almost constant so that the differences in wealth conditions of the European citizens are still extremely high.     

Converging on the learning curve: Theory and application to German regional data

Converging on the Learning Curve: Theory and Application to German Regional Data. — Studies finding convergence between regions are usually based on the assumptions of decreasing returns to overall capital and ubiquitous exogenous technical progress. In contrast, we derive convergence from a model with endogenous knowledge creation and knowledge spillovers which interact with the regional formation of human capital. The model allows for conditional convergence due to interregional knowledge dissemination which is an important determinant of the regional learning curve. In empirical estimates for 327 German regions, it is found that the characteristics of the knowledge and the human capital sectors have largely the impacts on convergence which are predicted by the model.     

Endowments vs. market potential: What explains the relocation of industry after the Polish reunification in 1918?

How did the location of industry across interwar Poland react to the Polish reunification? After more than 120 years of political and economic separation, Poland was reunified at the end of 1918. In consequence, the removal of internal tariff barriers and improved infrastructure strengthened the domestic market, while foreign market relations were cut off. Similarly, the geographical distribution of factor endowments was changed, for example, through internal migration. How did these forces interact to determine the location of industry? We survey the dynamics of industrial location between 1902 and 1925-1937 and estimate a specification that nests market potential and comparative advantage to quantify their respective impact during the interwar years. The results point to a role for both, comparative advantage and access to markets. We show that both statistically and economically the most important factors were the endowment with skilled labour and inter-industry-linkages.
