All-Units Discounts As A Partial Foreclosure Device, Yong Chao, Guofu Tan

Yong Chao

All-units discounts (AUD) are pricing schemes that lower a buyer’s marginal price on every unit purchased when the buyer’s purchase exceeds or is equal to a pre-specified threshold. The AUD and related conditional rebates are commonly used in both final-goods and intermediate-goods markets. Although the existing literature has thus far focused on interpreting the AUD as a price discrimination tool, investment incentive program, or rent-shifting instrument, the antitrust concerns on the AUD and related conditional rebates are often their plausible exclusionary effects.

In this article, we investigate strategic effects of volume-threshold based AUD used by a dominant firm in the …

Bargaining In Hospital Merger Models, David J. Balan, Keith Brand

David J. Balan

Hospital prices for commercially-insured patients are generally set through bilateral negotiations with health insurance companies. Reflecting common industry practice, contemporary models of hospital/health insurer bargaining usually assume that multi-hospital systems bargain on an all-or-nothing basis. However, hospitals within systems may bargain separately, and a commitment to do so is sometimes put forward as a remedy for an otherwise anticompetitive merger. We analyze and compare the merger-induced changes in equilibrium prices in a Nash Bargaining framework under these two modes of bargaining. We show that, while the magnitude of price effects under either mode depends critically on the degree of pre-merger …

Strategic Effects Of Three-Part Tariffs Under Oligopoly, Yong Chao

Yong Chao

The distinct element of a three-part tariff, compared with linear pricing or a two-part tariff, is its quantity target within which the marginal price is zero. This quantity target instrument enriches the firm's strategy set in dictating the competition to a specific level, even in the absence of usual price discrimination motive. With general differentiated linear demand system, the competitive effect of a three-part tariff in contrast to linear pricing depends on the degree of substitutability between products: competition is intensified when two products are more differentiated, yet softened when two products are more substitutable.

Effects Of Ad-Valorem Taxes On Location Decision Under Free Entry Cournot Oligopoly, Yeung-Nan Shieh

Yeung-Nan Shieh

This paper examines the impact of the ad-valorem commodity tax as a policy device on the location decision of undifferentiated oligopolistic firms with free entry. It shows that: (1) When the distance between the plant location and the output market is held constant, the optimum location for the oligopolistic firm would be independent of the ad-valorem tax if the production function is homothetic, and (2) when the distance between the plant location and the output market is a decision variable, the optimum location for the oligopolistic firm will move closer to the output market if the demand function is linear …

Product Markets And Industry-Specific Training, Armin Schmutzler, Hans Gersbach

Armin Schmutzler

We develop a product market theory to explain why firms provide their workers with skills that are also useful to their competitors. Firms first decide whether to invest in industry-specific training, then make wage offers for each others’ trained employees and finally engage in imperfect product market competition. Equilibria with and without training can emerge. If competition is soft, firms invest in training if others do. Thereby, they avoid having to pay high wages for trained workers. Furthermore, we draw welfare conclusions from the analysis. Finally, we discuss how our ideas apply to supplier relationships and to general training.

Competition Policy Issues In The Consumer Payments Industry, Nicholas Economides

Nicholas Economides

We discuss the current structure of card networks that facilitate transactions between merchants and consumers. We find that presently fees for this intermediation are considerably higher than costs. This is facilitated by rules imposed by the card networks on the merchants that do not allow merchants to steer competition to cards that have lower fees. It has also been facilitated by the requirement that a merchant has to accept all cards of the same network (honor all cards rule) -- recently abolished in the US, as well as by the fact that the networks set the maximum interface fee between …

Regional Unemployment And Productivity In Europe, Luca De Benedictis, Roberto Basile

Luca De Benedictis

We analyse the relationship between regional unemployment and labour productivity in Europe, basing our empirical analysis on the predictions of a Neary-type General Oligopolistic Equilibrium trade model with efficiency-wages. Using semiparametric and dynamic panel data estimators and controlling for other factors, we give evidence of a nonlinear relationship between productivity and regional unemployment in Europe: with a level of productivity smaller than a certain threshold, this relationship is negative, while no relation occurs in the case of higher productivity regions. This evidence proves an important role of a wage-floor (induced by efficiency wages and exacerbated by institutional factors) under which …
