Scale Economies and Synergies in Horizontal Merger Analysis

Three years ago, the Antitrust Division and the Federal Trade Commission revised their Horizontal Merger Guidelines to articulate in greater detail how they would treat claims of efficiencies associated with horizontal mergers: claims that are frequently made, as for instance in the recently proposed merger between Heinz and Beech-Nut in the market for baby food. While these revisions to the Guidelines have a solid economic basis, they leave open many questions, both in theory and in practice. In this essay, we evaluate some aspects of the treatment of efficiencies, based on three years of enforcement experience under the revised Guidelines, including several litigated mergers, and based on economic principles drawn from oligopoly theory regarding cost savings, competition, and consumer welfare.

Legislate or Delegate? Bargaining over Implementation and Legislative Authority in the European Union

In this article we explain how actors' ability to bargain successfully in order to advance their institutional preferences has changed over time as a function of the particular institutional context. We show how actors use their bargaining power under given institutional rules in order to shift the existing balance between legislation and delegation, and shift the rules governing delegation in their favor, between formal treaty changes. We argue that a collective actor's preferences over delegation is a function of whether the actor has more ability to influence policy through delegation or through legislation. We go on to argue that the degree to which a specific actor's preferences can prevail (in a setting in which different actors have different preferences) will depend upon its bargaining power under existing institutional rules, i.e. its ability to impede or veto policy in order to change the division between legislation and delegation and the rules of delegation. Our primary focus in this article is on choice over procedure; i.e. the battles over whether or not delegation or legislation should be employed. We maintain a secondary focus on change in procedure, examining how different procedures of comitology have come into being and been removed from the table. We examine the evolution of the debate over comitology and implementation, over five key periods. We scrutinize how actors within these periods seek to shift the balance of legislation and delegation and the rules of delegation according to their preferences. Our conclusions assess our empirical findings on the basis of our model.accountability; European Commission; Council of Ministers; European Parliament; European Parliament

Information, Decisions, and the Limits of Informed Consent

For many years, the heart\u27s wish of bioethics has been to confide medical decisions to patients and not to doctors. The favoured key to doing so has been the doctrine of informed consent. The theory of and hopes for that doctrine are well captured in the influential case of Caterbury v. Spence: \u27[t]rue consent to what happens to one\u27s self is the informed exercise of a choice, and that entails an opportunity to evaluate knoledgeably the options available and the risks attendant upon each\u27

Does Information and Agreement Equal Informed Consent?

The following essay is based on a talk delivered last summer in England and on the chapter Information, Decisions, and the Limits of Informed Consent, in (Michael Freeman and Andrew D. E. Lewis, eds.) Law and Medicine: Current Legal Issues 2000, Volume 3 (Oxford University Press, 2000). This version appears with permission of the publisher. For many years, a principal labor of bioethics has been to find a way of confiding medical decisions to patients and not to doctors. The foremost mechanism for doing so has been the doctrine of informed consent. Anxious as bioethicists and courts have been to promulgate this doctrine, they have been less anxious to discover how well it works. The bioethical tradition has been far more interested in articulating principle than testing practice

Compression of 1030-nm femtosecond pulses after nonlinear spectral broadening in Corning^® HI 1060 fiber:Theory and experiment

We present the design and implementation of femtosecond pulse compression at 1030 nm based on spectral broadening in single-mode fiber, followed by dispersion compensation using an optimized double-pass SF11 prism pair. The source laser produced 1030-nm 144-fs pulses which were coupled into Corning® HI 1060 fiber, whose length was chosen to be 40 cm by using a pulse propagation model based on solving the generalized nonlinear Schrödinger equation. A maximum broadening to 60-nm bandwidth was obtained, following which compression to 60 ± 3 fs duration was achieved by using a prism-pair separation of 1025 ± 5 mm

Rational choice meets the new politics: choosing the Scottish Parliament’s electoral system

Although there has been extensive research about electoral system choice at the national level, we know relatively little about the dynamics of deciding the rules of the game for sub-state institutions. This article examines the factors that influenced the choice of a proportional electoral system for the new Scottish Parliament in 1999. Through the use of archival sources and interviews with key participants, we challenge the conventional rational choice explanation for the adoption of the mixed-member proportional (MMP) system. Although rational considerations on the part of the Labour Party were involved in the choice of MMP, our findings suggest that, as at the national level, theories of electoral system choice need to consider normative values as well
