This study examines barriers to entry in the South African retail banking informed by Capitec's experiences as an entrant. In some ways Capitec's experience is exceptional. It surged ahead early attempts to bank the excluded from banks such as Ubank (former Teba Bank) and the Mzansi initiative....

Market power on each side of a multisided platform, whether in the form of increasing prices or decreasing quality, is constrained by the risk of losing sales on the other sides. That tends to weaken market power on each side and encourages platforms to keep prices lower and quality higher than...

Theoretically and experimentally, we generalize the analysis of acquiring a company (Samuelson and Bazerman 1985) by allowing for competition of both, buyers and sellers. Naivety of both is related to the idea that higher prices exclude worse qualities. While competition of naive buyers...

In liberalized electricity markets strategic firms compete in an environment characterized by fluctuating demand and non-storability of electricity. While spot market design under those conditions by now is well understood, a rigorous analysis of investment incentives is still missing. Existing...

The following paper aims at studying the competitive effect of the entry in the gas market of importers of liquefied natural gas (LNG hereafter). In particular we would like to analyze whether the construction of LNG terminals and the entry of LNG importers can have a positive effect on the gas...

An important issue in many antitrust lawsuits involving professional sports leagues and their member teams is the extent to which franchises within the same, and across different, professional sports leagues compete with one another for fans and advertisers. Complicating the issue is the fact...

We study price discrimination in a market in which two firms engage in Bertrand competition. Some consumers are contested by both firms, and other consumers are “captive” to one of the firms. The market can be divided into segments, which have different relative shares of captive and...

Duopolists selling differentiated products can generate less consumer surplus than a monopoly selling one of the products. In a Hotelling-type model where a monopoly supplies more than half of potential consumers, but not all, entry by a rival leads to a duopoly price that is higher than the...

While competition between firms producing substitutes is well understood, less is known about rivalry between complementors. We study the interaction between firms in markets with one-way essential complements. One good is essential to the use of the other but not vice versa, as arises with an...
