The Regulation of Predatory Firms

This article investigates the issue of predation by a regulated firm. Since it has private information, a regulated firm obtains higher rents in case of successful predation: the fewer the competitors, the higher the marginal social value of the regulated firm's effort and the higher the informational rents. Both principals (the investor of a "target" firm and the regulator) have to provide some incentives to prevent predation: the investor has to reduce the sensitivity of refinancing to predation; the regulator has to lower the gain of successful predation. It is shown that there is a trade-off between the power of the regulatory incentive scheme and the regulated firm's incentives to prey. In addition, as deterring predation is costly, the investor and the regulator compete when offering contracts: each wants to free-ride on the other. Hence, predation may occur in equilibrium although it makes both principals worse off.

International Expansion,Diversification and Regulated Firm Nonmarket Strategy

Previous studies have shown that regulated firms diversify for reasons that are different than for unregulated firms. We explore some of these differences by providing a theoretical model that starts by considering the firm–regulator relationship as an incomplete information issue, in which a regulated incumbent has knowledge that the regulator does not have, but the firm cannot convey hard information about this knowledge. The incumbent faces both market and nonmarket competition from a new entrant. In that context, we show that when the firm faces tough nonmarket competition domestically, going abroad can create a mechanism that makes information transmission to the regulator more credible. International expansion can thus be a way to solve domestic nonmarket issues in addition to being a catalyst for growth. Copyright © 2012 John Wiley & Sons, Ltd.

Incomplete regulation, market competition and collusion

Regulators often do not regulate all firms competing in a given sector. Due to product substitutability, unregulated competitors have incentives to bribe regulated firms to have them overstate their costs and produce less, thereby softening competition. The best collusion-proof contract entails distortions both for inefficient and efficient regulated firms (distortion ‘at the top’). But a contract inducing active collusion may do better by allowing the regulator to ‘team up’ with the regulated firm to indirectly tax its competitor. The best such contract is characterized. It is such that the unregulated firm pays the regulated one to have it truthfully reveals its inefficiency. We finally compare those contracts.     

Editorial

This paper investigates the long-standing Swiss dualistic approach to banking supervision, whereby banks' external auditors report not only to shareholders under company legislation but also report to, and undertake work for, the banking regulator under banking legislation. The dual role raises the issue of whether auditors are sufficiently independent of management to act fairly with respect to both shareholders and supervisors. In contrast, recent literature and policy-making on regulation advocates the need to close the distance between regulators and those regulated, and the Basel Committee on Banking Supervision has advocated a closer relationship between banking supervisors and banks' external auditors. The paper investigates the dual role by providing empirical evidence from interviews undertaken with Swiss audit partners, and analysis of documentary material from the Swiss banking regulator and IMF. The paper concludes inter alia that the Swiss dualistic system ‘works’ because it is supported by a layered regulatory approach at audit firm, national and international levels to ensure and safeguard auditor independence and competence. Whether such a system would work elsewhere depends on national factors such as conceptions of the nature of corporate governance and of the state, and prevailing views on private actors undertaking public roles.
