Early internet IPOs versus subsequent entrants

This paper examines whether investors in early Internet IPOs earned superior returns to those who invested in later entrants. We document three differences between early public firms in a new Internet technology and their followers: underpricing, operating characteristics at the IPO, and stock price performance after the IPO. We find that there is value in going public relatively early in a new Internet technology. Specifically, long-term returns are significantly higher for the early entrants. We also find evidence, consistent with previous studies that examine hot IPO markets, that the early public firms have better operating characteristics at the IPO than later entrants.     

Unternehmensübergreifendes Kostenmanagement in der Supply Chain

Die Kostensenkungspotenziale des Supply Chain Managements müssen durch ein unternehmensübergreifendes Kostenmanagement ausgesch?pft werden. Das Kostenmanagement muss an den spezifischen Neuerungen des Supply Chain Managements gezielt ansetzen. Das hier vorgeschlagene Verfahren umfasst drei Stufen: die Schnittstellengestaltung, die gemeinsame Produktentwicklung sowie die Lieferantenertüchtigung.     

The effect of fertility on labour force participation: The Spanish evidence

Abstract. The aim of this paper is to estimate the effect of fertility on the decision of labour force participation of married females in Spain, allowing for the existence of unobserved characteristics that affect both fertility and participation. We use a pooling of five waves of the European Household Panel for Spain (1994–1998). Results indicate that not taking into account the unobserved characteristics that affect both variables imposes on average a strong downward bias on the true effect of fertility on participation. This bias is especially strong for highly educated females. We are grateful to Raquel Carrasco and an anonymous referee for helpful comments.

A note on Bossert,Pattanaik and Xu's “Choice under complete uncertainty: axiomatic characterization of some decision rules”

Summary. Recent work by Bossert, Pattanaik and Xu provides axiomatic characterizations of some decision rules for individual decision making under complete uncertainty. This note shows that, in the case of two of these rules, they do not satisfy one of the axioms used for their characterization. A counterexample illustrating this fact is provided, as well as an alternative way to characterize the two rules under consideration, mantaining as far as possible the original axioms proposed by Bossert, Pattanaik and Xu. Received: November 3, 2000; revised version: March 1, 2002 RID="*" ID="*" I am grateful for the encouragement and support of Professor Prasanta Pattanaik. I thank also the suggestions of two anonymous referees. This work was made during an academic visit to the Department of Economics of the University of California in Riverside (UCR).

Risk compensation in wages – a replication

We use data from Germany, The Netherlands, Portugal and Spain to test for the effect of earnings variation on individual earnings. We replicate estimates for the USA and find that the variance of earnings in an occupation affects individual wages positively while the skewness of earnings has a negative effect. Both results are in conformity with wage compensation for risk averse workers.

Term structure and the estimated monetary policy rule in the Eurozone

In this paper we estimate a standard version of the New Keynesian Monetary (NKM) model augmented with term structure in order to analyze two issues. First, we analyze the effect of introducing an explicit term structure channel in the NKM model on the estimated parameter values of the model, with special emphasis on the interest rate smoothing parameter using data for the Eurozone. Second, we study the ability of the model to reproduce some stylized facts such as highly persistent dynamics, the weak comovement between economic activity and inflation, and the positive, strong comovement between interest rates observed in actual Eurozone data. The Sect. 3 implemented is a classical structural method based on the indirect inference principle. We are grateful to Eduardo Ley, two anonymous referees and seminar participants at the XXXI Simposio de Análisis Económico (Oviedo, Spain) and Bank of Spain for their useful comments.
