This paper presents a competitive supply chain network design problem in which one, two, or three supply chains are planning to enter the price-dependent markets simultaneously in uncertain environments and decide to set the prices and shape their networks. The chains produce competitive products either identical or highly substitutable. Fuzzy multi-level mixed integer programming is used to mo...

This paper studies the effects of generic entry on post-patent price competition for 18 prescription drugs recently exposed to competition. An independent, validating test of the “generic competition paradox” is conducted using a newly created data set. Each generic entrant is associated with an average 1% increase in the branded price. The one-way error component model accounts for intermolecu...

Using Japanese scanner data of transaction prices and sales for more than 1,600 commodity groups from 1988 to 2008, we find a statistically significant negative correlation between the frequency of price changes and the degree of market concentration. We also find that structural factors of a distribution channel are significantly correlated with rigidity in retail prices. Decomposing the frequ...

This paper examines the first 16 months of competition in the German market for long-distance voice telephony on the fixed network. It concentrates on price level and price structure. Competition induced by the entry of both network operators and switch-based service providers decreased the price level substantially. Furthermore, after initial attempts to design innovative price structures, mos...

In this paper, we present a formal model of the pharmaceutical market as a market with price competition between the original and the generic alternative. The generic substitutes are perceived by the consumers as di¤erentiated products, even though they are chemically identical. In addition, because of price regulation, a low ”limit price” will be a credible commitment not to increase prices up...

We introduce consumer loss aversion into the Salop (1979) model of price competition with differentiated products. Firms face uncertain costs of production, and after observing their own cost realizations simultaneously set prices. A consumer derives “gain-loss utility” from comparing the purchase price and her satisfaction with the acquired product to her recent expectations regarding the same...

It has been said that the National Recovery Administration operated under a law which gave it legislative, executive, and judicial functions. But in retrospect it seems to have scarcely passed beyond the legislative pfiase in most of the matters which came under its jurisdiction. The essential part of its record for the economist is the record of the attempts to formulate policy in connection w...

In this note we show that the results developed in Singh and Vives (1984) are sensitive to the duopoly assumption (Rand Journal of Economics 15, 546-554). If there are more than two firms, prices may be higher under price competition than under quantity competition. This will be the case if quality differences are large and goods are complements. If goods are substitutes, high-quality firms may...

This paper examines competition in e-markets by comparing price levels and price dispersion in the on-line music market. The data consists of price information on CDs pure-play Internet and hybrid firms in North American and European markets. The sellers are divided in groups according to a geographical location, a brand valuation and a variety of product offerings. We find that pure price leve...
