Algorithmic Game Theory

The paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier (1) has superior information about the cost of the project and (2) invests in cost reduction. The main result states that, under risk neutrality, the supplier announces an expected cost and is given an incentive contract linear in cost overruns. This (optimal) contract moves toward a fixed-price contract as the announced cost decreases. An investment choice is then introduced and the use of a rate-of-return regulation is studied.

Using Cost Observation to Regulate Firms

In the typical regulatory scheme a franchised monopoly has little incentive to reduce costs. This article proposes a mechanism in which the price the regulatedfirm receives depends on the costs of identical firms. In equilibrium each firm chooses a socially efficient level of cost reduction. The mechanism generalizes to cover heterogeneous firms with observable differences. Medicare's prospective reimbursement of hospitals by using diagnostically related groups is a scheme very similar to the one outlined here.

A Theory of Yardstick Competition

This paper begins with a sketch of the New Institutional Economics, with special emphasis on the ‘institutional environment’ (North and others) and the ‘institutions of governance’ (Coase and others) Thereafter the paper mainly emphasizes the applications of transaction cost economics to the study of governance, the object being to effect an economizing alignment between transactions, which differ in their attributes, and governance structures (firms, markets, hybrids, bureaus), which differ in their cost and competence I raise a series of issues – phenomena of interest, describing human agents, describing firms, purposes served, scaling up – to which any would-be theory of the firm should be expected to speak and indicate how transaction cost economics responds to each I thereafter describe the mechanisms through which transaction cost economics is implemented and develop some of the core conceptual supports out of which it works Applications to public bureaus, strategic management, and intractable transactions are sketched

Transaction Cost Economics: How It Works; Where It is Headed

Modelling and forecasting the diffusion of innovation – A 25-year review

This paper describes an incentive mechanism that is shown to enforce the use of Ramsey prices by multiproduct monopolies. The constraint given is simple. It limits information requirements on the regulatory agency to bookkeeping data of the firm. Its implementation could be easily controlled by outside courts or auditors. The process, therefore, makes use of invisible hand properties shifting the workload of welfare optimization from the regulatory agency to the regulated firm.

A regulatory adjustment process for optimal pricing by multiproduct monopoly firms

Handbook of Telecommunications Economics

Over the last 20 years, incentives in general and price caps in particular have breathed new life into public utility regulation. Price caps successfully combine incentives for cost reduction with incentives for more efficient pricing. These properties also facilitate opening public utility sectors to competition. Relatively tight price caps likely imply the right amount of competition, when the underlying natural market structure is unknown. While price caps make a regulated incumbent competitively more aggressive, this aggression is likely to improve on the unregulated outcome. Potentially anticompetitive behavior by the incumbent has led to regulation of essential inputs on the basis of benchmarked costs. Benchmarked costs should evolve into price caps for essential inputs and eventually lead to partial deregulation of end-user prices.

Incentive Regulation and Competition in Public Utility Markets: A 20-Year Perspective

Without access of networks to each other, competition in the telecommunications sector would hardly have spread so quickly. Such mutual access is necessary for carriers to provide ubiquitous service and enable endusers to call and be called by anybody without subscribing to a system-wide monopolist. One-way access concerns bottleneck inputs provided by an incumbent network to entrants, while two-way access concerns the interconnection between networks. Whereas one-way access regulation is exclusively driven by containment of market power, two-way access is additionally affected by collusion possibilities. Among the numerous pricing rules discussed, none clearly dominates. This article provides a roadmap vis-a-vis the competing policy objectives for access price regulation.
