Activist NGOs have increasingly foregone public politics and turned to private politics to change the practices of firms and industries. This paper focuses on private politics, activist strategies, and nonmarket strategies of targets. A formal theory of an encounter between an activist organization and a target is presented to examine strategies for lessening the chance of being a target and for addressing an activist challenge once it has occurred. The encounter between the activist and the target is viewed as competition. At the heart of that competition is an activist campaign, which is represented by a demand, a promised reward if the target meets the demand, and a threat of harm if the target rejects the demand. The model incorporates target selection by the activist, proactive measures and reputation building by a potential target to reduce the likelihood of being selected as a target, fighting a campaign, and credible commitment.

This paper presents a theory of parliamentary systems with a proportional representation electoral system, a formateur selected based on party representation in parliament, and parties that cannot commit to the policies they will implement once in government. Government formation involves efficient proto-coalition bargaining, and elections yield unique strong Nash equilibrium outcomes. Depending on the status quo, minimal-majority, surplus, or consensus governments can form. If parties and voters are myopic and the status quo is subject to shocks, consensus governments and centrist policies occur only in a crisis. Otherwise, governments are minimal winning, and policies reflect only the preferences of the government parties.

This paper studies organizational structure and incentives within a company, Citibank, that has an explicit and evolving global business strategy. The paper focuses on Citibank's corporate banking business, which in the mid-1990's underwent major changes in its strategy that, in turn, were accompanied by two major reorganizations and implementations of a new incentive compensation system. Citibank's corporate banking business in OECD markets moved froma geography-based organization to one that was multi-dimensional, with the customer dimension given first priority, the product dimension given second priority, and the geography dimension significantly de-emphasized. Citibank thus represents an excellent setting for examining the interplay among strategy and organizational structure in a complex, global company.

An informational alliance involves the consolidation of the private information of independent suppliers in anticipation of a contracting opportunity with a principal. An informational alliance is an intermediate form of organization between the consolidation of information as in a merger and the suppliers remining separate entities. It can Pareto dominate a merger, independent contracting, and hierarchical contracting, so a principal can benefit by allowing suppliers to organize the supply network. An informational alliance forms at the nexus of internally-verifiable private information. The principal's contracting problem then involves a participation condition with a reservation value that is a function of type.

This paper investigates how a designer of an organization (referred to as the regulator) should organize a production activity in which two different units produce components and where each unit has private information about its costs. Three organizational structures are analyzed. In the first (informational consolidation), the regulator contracts with a consolidated unit that produces both components. In the second (informational decentralization) the regulator independently contracts with the producer of each component. In the third (informational delegation), the regulator contracts with one of the units, which in turn subcontracts with the other. In each case, the regulator's optimal mechanism consisting of payment and output schedules is fully characterized. Informational consolidation and informational decentralization yield different output schedules. Under informational decentralization, the optimal output schedule may not depend on the sum of the marginal costs of each component, but when it does, the regulator strictly prefers informational consolidation to informational decentralization. Informational delegation is shown to be equivalent to informational decentralization when the regulator can observe the contracting between the units.

This paper contains an agency-theoretic analysis of procurement contracts in which the government designs optimal linear contracts for a risk-averse supplier in the presence of moral hazard, private information, and imperfect monitoring. Optimal contracts deviate from first-best risk sharing. The direction of the deviation depends on t he relative severity of the moral hazard and private information problem s and on the precision of the monitor. In contrast to the usual result in the moral hazard literature, the government may, in some cases, prefer that the effort of the supplier be taxed. Choice of the precision of the monitor and the categories of costs covered by the monitor are also studied.

This paper considers a multiperiod model of a regulated firm that has (stationary) private reformation which may be revealed through performance. If it cannot make commitments to future policies, the regulator has an incentive to exploit any information the firm reveals, and Laffont and Tirole show that there is no regulatory policy that is separating over any closed interval. A "fairness" arrangement is proposed in which the firm agrees not to quit if in future periods the regulator allows it to earn a nonnegative profit given the type it revealed in earlier periods, The properties of such arrangements are studied, and an example is presented in which both the firm and the regulator prefer a fairness arrangement to a policy feasible without commitment.

This article characterizes the optimal procurement contract for a monopsonistic purchaser who contracts with a risk-averse supplier with private information about his costs and who contributes an unobservable effort. The costs incurred by the supplier may be uncertain, and the purchaser has access to a monitor of costs that may be subject to noise that complicates risk sharing. The purchaser prefers to respond to the observability problem with a fixed-price contract and to respond to the private information problem with a cost-plus contract. With uncertain costs and a perfect monitor the optimal contract relieves the supplier of some risk, and the purchaser prefers that the effort of the supplier be subsidized. With deterministic costs and a noisy monitor the optimal contract places risk on the supplier, and the purchaser may prefer that the effort of the supplier be taxed.

Regulation typically involves a continuing relationship between a regulator and a firm, and that relationship is often complicated by asymmetric information. A multiperiod model of this relationship is analyzed in which a regulated firm has private information about its costs which may changed over time in a manner observable only to the firm. The regulator is assumed to be able to commit to a policy for the entire regulatory horizon, and the optimal pricing policy is shown to depend on an informativeness measure that indicates how information by the firm in one period will be used in future periods.

This article analyzes a model of a regulated firm that is better informed about its cost function than is the regulator. By auditing at a cost, however, the regulator is assumed to be able to observe the realized cost of the firm. If the regulator "finds" that the firm had misrepresented its costs at the time at which prices were set, he can order a refund to consumers. In the optimal policy the regulator audits when the firm reports for pricing purposes that its costs will be high and orders a refund when the audit finds that realized costs are lower than anticipated, given the original report. A separation result that obtains for an important case indicates that the initial pricing decision is independent of the auditing decision. The auditing decision, however, depends on the price that was initially set. The optimal auditing strategy is characterized and the nature of the welfare gains are identified. The methodology used in the analysis involves the characterization of an equilibrium of a revelation game with an ex post observable.
