Exploring the Intensive and Extensive Margins of World Trade

World trade evolves at two margins. Where a bilateral trading relationship already exists it may increase through time (intensive margin). But trade may also increase if a trading bilateral relationship is newly established between countries that have not traded with each other in the past (extensive margin). We provide an empirical dissection of post–World War II growth in manufacturing world trade along these two margins. We propose a “corner-solutions version” of the gravity model to explain movements on both margins. A Tobit estimation of this model resolves the so-called “distance puzzle”. It also finds more convincing evidence than recent literature that WTO-membership enhances trade. JEL no. F12, F15     

INITIAL PUBLIC OFFERINGS: GOING BY THE BOOK

In the U.S., and increasingly in other countries as well, IPO securities are marketed to investors in a process known as "book-building"—one that amounts to polling institutional investors to establish a demand schedule for the issue and then allotting stock to individual investors according to the strength of their professed interest. Although book-building methods require use of discriminatory tactics that have attracted strong criticism from investors and regulators, this article defends such practices by demonstrating that book-building is more efficient than alternative methods. It effectively allows issuers to increase the net proceeds of their offerings by making better use of information about market demand conditions.
In the process of explaining the efficiency of the book-building method, this article also offers a plausible explanation for a phenomenon that has long puzzled economists: the systematic underpricing of IPOs. The key to the success of a book-building effort lies in the use of a strategic pricing and allocation policy designed to offset the investor's incentive to understate his or her interest in an IPO. By committing to favor investors who provide strong indications of interest with relatively large allocations of underpriced shares, the investment bank can limit the distortion of investor's incentives in bidding and so increase the level of proceeds the issuing firm can expect to generate from its IPO.     

Global Integration in Primary Equity Markets: The Role of U.S. Banks and U.S. Investors

We examine the costs and benefits of the global integrationof initial public offering (IPO) markets associated with thediffusion of U.S. underwriting methods in the 1990s. Bookbuildingis becoming increasingly popular outside the United States andtypically costs twice as much as a fixed-price offer. However,on its own, bookbuilding only leads to lower underpricing whenconducted by U.S. banks and/or targeted at U.S. investors. Formost issuers, the gains associated with lower underpricing outweighedthe additional costs associated with hiring U.S. banks or marketingin the United States. This suggests a quality/price trade-offcontrasting with the findings of Chen and Ritter, particularlysince non-U.S. issuers raising US$20 million–US$80 millionalso typically pay a 7% spread when U.S. banks and investorsare involved.     

Multilateral trade liberalization: Some general equilibrium simulation results for Austria

This paper uses the Michigan Model of World Production and Trade for a quantitative evaluation of the general equilibrium effects of various multilateral trade liberalization scenarios on the Austrian economy. The analysis is motivated by the recent incorporation into the model of an original input-output table for Austria, and by a severe shortage of knowledge on the effects of liberalization on the Austrian economy. In addition to the actual Tokyo-round tariff cuts, the paper concentrates on an almost complete multilateral elimination of post-Tokyo-round protection, including the most important non-tariff trade barriers. The paper also reports on some aggregate price and exchange rate effects, but the primary focus of the analysis will be sectoral adjustment, characterized by changes in employment, per-unit value added, and returns to sector-specific capital.

Zusammenfassung In Österreich besteht ein gewisses Defizit an systematischen quantitativen Analysen der bestehenden Handelsprotektion bzw. der Effekte, die eine Beseitigung dieser Protektion — etwa im Rahmen der laufenden GATT-Verhandlungsrunde — haben kann. In dieser Arbeit wird das an der University of Michigan (USA) entwickelte Welthandelsmodell für eine solche Analyse verwendet. Mit Hilfe dieses viele Länder umfassenden und empirisch implementierten allgemeinen Gleichgewichtsmodells werden die Auswirkungen verschiedener Szenarien der multilateralen Liberalisierung des internationalen Handels, einschließlich der Beseitigung nichttarifärer Handelshemmnisse, auf die österreichische Volkswirtschaft untersucht. Diese Untersuchung wurde möglich durch die mittlerweile erfolgte Aufnahme der österreichischen Input-Output-Daten in das Michigan-Modell. Sowohl aggregierte als auch sektorale Effekte werden berechnet, wobei die letzteren Aufschluß geben können über allenfalls zu erwartende Anpassungsschwierigkeiten.

All simulations reported on in this paper were carried out while I was visiting scholar at the University of Michigan in 1987–88. I am deeply indebted to Alan Deardorff and Robert Stern for having me participate in their ongoing research project on General Equilibrium Trade Policy Modeling, for offering me unlimited use of their computational model, and for their continuous support and encouragement. I am also grateful to John Alfaro and Jon Haveman for computational assistance. Thanks are due to Josef Richter and Gottfried Tappeiner for their cooperation in providing the Austrian input-output table in machine readable form.     

Costs, Institutional Mobility Barriers, and Market Structure: Advertising Agencies as Multiproduct Firms

What accounts for the diversity and limited concentration that has long characterized the organization of the advertising agency industry? This question is addressed by treating an advertising agency as a multiproduct firm. The firm's product line or service mix is defined in terms of the set of different media categories where an agency places the advertising messages that it creates on behalf of its clients. Evidence is presented indicating that the structure of demand and costs in the advertising agency industry conforms to the conditions that MacDonald and Slivinski showed were required for an industry to sustain an equilibrium with diversified firms. Building on this framework, we formulate a set of three hypotheses relating to the realization of product-specific scale and scope economies. The first two hypotheses posit that given low fixed costs and minimal entry barriers, both media-specific scale and scope economies are available and can be exploited by relatively small-size agencies. The third hypothesis suggests that large agencies may experience diseconomies of scope as a consequence of excessive diversification induced by two pervasive industry institutional phenomena: (1) “bundling” of agency services to match client demand for a mix of media advertising, and (2) “conflict policy,” which prohibits an agency from serving competing accounts and operates as a mobility constraint. Utilizing a multiproduct cost function, we estimate media-specific scale and scope economies for a cross section of 401 U.S. agencies in 1987. The results obtained support the set of three hypotheses outlined above. The paper concludes with a discussion of the implications of these findings for the restructuring currently underway in this industry.     

The Lévy LIBOR model

Models driven by Lévy processes are attractive because of their greater flexibility compared to classical diffusion models. First we derive the dynamics of the LIBOR rate process in a semimartingale as well as a Lévy Heath-Jarrow-Morton setting. Then we introduce a Lévy LIBOR market model. In order to guarantee positive rates, the LIBOR rate process is constructed as an ordinary exponential. Via backward induction we get that the rates are martingales under the corresponding forward measures. An explicit formula to price caps and floors which uses bilateral Laplace transforms is derived.     

Logics,Leaders, Lab Coats: A Multi‐Level Study on How Institutional Logics are Linked to Entrepreneurial Intentions in Academia

Situated in the context of academia, this study integrates ideas from institutional theory, person‐environment fit theory and leadership research to conceptualize and examine the cross‐level link between the organizational‐level institutional logic of research commercialization and the entrepreneurial intentions of researchers. Multi‐level analyses based on a sample of 254 researchers working for 85 research group leaders in 49 German research institutes reveal that two distinct attributes of research group leaders – that is, their track records of entrepreneurial behaviour and their entrepreneurial intentions – play a significant role in transmitting the organizational‐level logic to the individual level. We also observe a complementary interaction between organizational‐level commercialization logic and the entrepreneurial track records of leaders. We discuss how these findings advance our understanding of science commercialization through academic entrepreneurship and how they inform institutional theory and theory development in other domains of entrepreneurship research.
