We conduct experiments testing the relationship between excess capacity and pricing in repeated Bertrand-Edgeworth duopolies and triopolies. We systematically vary the experimental markets between low excess capacity (suggesting monopoly) and no capacity constraints (suggesting perfect...

We present a laboratory experiment on the impact of price framing on consumer decision making. Consumer subjects face a search market where two sellers offer a homogenous good. We examine six different price frames with linear per-unit pricing (that is displayed as such) serving as a benchmark....

The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price...

We analyse how the market design influences the bidding behaviour in multi-unit auctions, such as wholesale electricity markets. It is shown that competition improves for increased market transparency and we identify circumstances where the auctioneer prefers uniform to discriminatory pricing....

We study an extension of the model of Rubinstein (1993) to two firms, competing in a market with consumers who are boundedly rational with respect to processing information. The cognitive bound forces customers to partition the price space. Rubinstein shows that a monopolist is able to earn a...

Most products are produced and sold by supply chain networks, where an interconnected network of producers and intermediaries set prices to maximize their profits. I show that there exists a unique equilibrium in a price-setting game on a network. The key distortion reducing both total profits...

In this paper, we characterize the set of pure strategy undominated equilibria in differentiated Bertrand oligopolies with linear demand and constant unit costs when firms may prefer not to produce. When all firms are active, there is a unique equilibrium. However, there is a continuum of...

We consider a procurement auction, where each supplier has private costs and submits a stepped supply function. We solve for a Bayesian Nash equilibrium and show that the equilibrium has a price instability in the sense that a minor change in a supplier's cost sometimes result in a major change...

Increased sales due to promotions could be at the expense of competitors: such sales come from consumers with relatively weak brand preferences. However, increased sales from brand loyal consumers could well cannibalize sales of the promoted brand. An unintended consequence of promotions is that...

Portuguese Abstract: Exploramos vários jogos diferenciais para simular a competição entre duas firmas em Preço, Publicidade, e Preço e Publicidade simultâneamente. Os resultados reforçam conclusões importantes na literatura e complementam-na, permitindo analisar a competição em dois...
