Thomas Tangerås, Research Institute of Industrial Economics and Johan Stennek, Research Institute of Industrial Economics have an interesting paper on Competition vs. Regulation in Mobile Telecommunications.
ABSTRACT: This paper questions whether competition
can replace sector-specific regulation of mobile telecommunications. We
show that the monopolistic outcome may prevail independently of market
concentration when access prices are determined in bilateral
A light-handed regulatory policy can induce effective competition. Call prices are close to the marginal cost if the networks are sufficiently close substitutes. Neither demand nor cost information is required.
A unique and symmetric call price equilibrium exists under symmetric access prices, provided that call demand is sufficiently inelastic. Existence encompasses the case of many networks and high network.
