Reform of European Merger Policy

The paper highlights the main drivers for merger policy reform in the European Union, including the consequences of the recent appeal court reverses. It discusses some of the substantive and procedural issues that the reform package should address, and outlines the reforms in progress. The author concludes that much of the reform package will be beneficial, but some important opportunities have been missed in this inevitably patchwork process.     

Adam Smith and Noneconomic Objectives

This note looks at Smith's critiques of bounties (read “subsidies”) on exports. Smith's analysis of bounties foreshadowed the basic trade policy framework of distortions and noneconomic objectives. While Smith did not develop the theory of distortions, he captured the logic of the theory of noneconomic objectives and actually ranked policy alternatives based upon their relative social costs. Corden (1957 ) first ranked tariffs versus production subsidies within a noneconomic objectives framework, and Johnson (1960 ) first used the term in its modern sense, but the formulation of the general framework lies with Smith.     

Organic constitutions and common law

Constitutions may be viewed as purely political instruments developed by wise and strong leaders and imposed on a loosely organized society. The alternate view taken in this paper sees a nation's constitution as being rooted in the norms of individuals that form communities and states. Constitutions grow from within; they are not imposed from outside. The history of constitutional development in England is part and parcel of the history of Common Law, which growing informally from small groups finally encompassed the nation-state to form a basis for constitutional government. The integrity of the law was rooted in the integrity of the individuals that formed the constitutional community. Alumni Professor of Economics, Clemson University.

The Impact of Option Introduction on Stock Return Variances: The Role of Bid-Ask Spreads, Return Autocorrelations, and Intrinsic Variances

The purpose of this paper is to examine changes in stock return variances following option introduction. The sample consists of National Market System stocks and employs both transaction returns and returns based on bid and ask quotes. Variances are decomposed into portions attributable to bid-ask spreads, return autocorrelations, and intrinsic variances. Spreads play a negligible role in explaining variance changes. A generally positive component to short-term autocorrelations falls following option introduction, increasing variances over short holding periods. Intrinsic variances fall prior to the October 1987 crash, but do not change after the crash with option introduction.     

Competitive and Information Effects of Cross-Border Stock Listings

We examine the effect of 269 cross‐border listings on rivals in the listing and domestic markets and find that U.S. rivals experience significant gains whereas domestic rivals do not. Both competitive and information effects are important in explaining the reaction of U.S. rivals. Regarding the competitive effects, the reaction of rivals is less favorable when listings originate in developed countries and more favorable when listing firms do not have prior operating presence in the United States. Regarding the information effects, the reaction is less favorable when listings are combined with equity offerings and more favorable when the listing is the first to occur within an industry.     

Accidents will happen: safety-critical knowledge and automated control systems

This article presents findings from a study of control operators that raise concerns about safety-critical knowledge, culture and training. It is argued that the adoption of automated control systems can hinder the transfer of knowledge amongst operators, and this becomes an increasingly serious hazard as tacit knowledge is lost because of employee turnover.
