An Empirical Examination of the Stated Purposes of Issuer Tender Offers to Purchase Common Stock

This paper documents the purposes of issuer tender offers to repurchase stock, as stated in Securities and Exchange Commission (SEC) disclosures, over the period 1994‐2006. We explore whether stated purposes relate to announcement period returns and find returns are significantly lower when repurchases replace dividends, distribute cash from unspecified sources, or occur subsequent to third‐party tender offers. Announcement period returns are significantly higher when repurchases are viewed by management as the best investment opportunity available or when they occur subsequent to previous repurchase programs. Finally, we find evidence in support of signaling theory and Jensen's (1986) agency cost of free cash flow theory.     

Historical Learning in the Design of WTO Rules: The EC Sugar Case

The Uruguay Round Agreement made significant changes to the governance of international trade. Trade rules and dispute settlement mechanisms were altered and a series of specific agreements provided for liberalisation across economic sectors. The Agreement on Agriculture, arguably the most difficult and contentious to negotiate, permitted the continued use of trade‐distorting instruments, both domestically and at the border. Rule‐enforcement in agriculture therefore relies crucially on the clarity of the rules. This paper provides an in‐depth study of a unique and critical case for understanding the new rules: the EC sugar regime. This policy was challenged unsuccessfully under the pre‐Uruguay Round rules, but successfully under the new rules. This case is particularly valuable in allowing us to isolate the effect of the Uruguay Round on agricultural trade disputes: the policy under challenge was essentially unchanged and the legal actions addressed the same concern – excessive export subsidisation. Drawing on primary and secondary materials and interviews with key policy actors, sugar is used to illustrate how those involved in the multilateral process learned from particular rule weaknesses revealed in earlier cases, revising those rules in the Uruguay Round in such a way that dispute panels can more readily and objectively determine rule breaches.     

A Hierarchical Marketing Communications Model of Online and Offline Media Synergies

We propose a new hierarchical model of online and offline advertising. This model incorporates within-media synergies and cross-media synergies and allows higher-order interactions among various media. We derive the optimal spending on each medium and the optimal total budget. We also develop three hypotheses on the effects of within- and across-media synergies on both the total budget and its allocation. We estimate media effectiveness as well as the within- and cross-media synergies of offline (television, print, and radio) and online (banners and search) ads using market data for a car brand. We show that both types of synergies —within-media (i.e., intra-offline) and cross-media (online-offline)— exist. We show how within- and cross-media synergies boost the total media budget and online spending due to synergies of the online media with various offline media.     

THE FUTURE OF MARKETS

In the 2009 Wincott Lecture, the author argues that in their approach to markets, economic researchers and policy-makers have focused too much on the role of prices as signals to guide resource allocation, at the expense of two possibly more important elements – markets as a process of discovery and markets as a mechanism for the diffusion of political and economic power. Government policies should support the market rather than particular industries, promote competition not concentration, and facilitate entry, not confer advantages on existing firms.     

Alternative evolutionary theories: A historical survey

Our overview has the objective of making our study relevant to bioeconomists. The need for the ‘alternatives’ to the Synthetic Theory of Evolution in social-economic studies was substantiated, for example, by Colombatto (Journal of Bioeconomics, 5, 1–25, 2003), who maintains that the natural-selection theory is ‘ill suited’ to describing evolutionary processes in economics. He proposed an alternative ‘non-Darwinian’ approach by equating the ‘non-Darwinian’ approach with a definite version of neo-Lamarckism. Yet, as we will show, there is a palette of alternative approaches within and beyond the neo-Lamarckism. We hope to give bioeconomists more choice in their theoretical modeling and constructing of analogies between biology and economics. It will also be shown that in the light of suggested definitions the concept of ‘universal Darwinism’ recently discussed in bioeconomics makes little sense as a generalizing category. In addition, in the concluding part of the paper we demonstrate that the majority of alternative approaches are far from being pigeonholed as archaic and once and for all wiped off the theoretical landscape. On the contrary, in recent years one can observe some revival of interest in the theoretical ‘heresies’.      

Corporate governance, takeovers and the role of the non-executive director

The takeover mechanism may have some effect on disciplining managers - but it also allows them to spend shareholders money on self promotion. The authors of this paper argue that if we had a better system of corporate governance with a revitalised role for independent directors fewer takeovers would occur, and calls for reform of the acquisition market would diminish.
