The Price of Options Illiquidity

The purpose of this paper is to examine the effect of illiquidity on the value of currency options. We use a unique dataset that allows us to explore this issue in special circumstances where options are issued by a central bank and are not traded prior to maturity. The value of these options is compared to similar options traded on the exchange. We find that the nontradable options are priced about 21 percent less than the exchange-traded options. This gap cannot be arbitraged away due to transactions costs and the risk that the exchange rate will change during the bidding process.     

Semiparametric and nonparametric testing for long memory: A Monte Carlo study

The finite sample properties of three semiparametric estimators, several versions of the modified rescaled range, MRR, and three versions of the GHURST estimator are investigated. Their power and size for testing for long memory under short-run effects, joint short and long-run effects, heteroscedasticity andt-distributions are given using Monte Carlo methods. The MRR with the Bartlett window is generally robust with the disadvantage of a relatively small power. The trimmed Whittle likelihood has high power in general and is robust except for large short-run effects. The tests are applied to changes in exchange rate series (daily data) of 6 major countries. The hypothesis of no fractional integration is rejected for none of the series.     

Return and risk in initial public offerings of both shares and warrants

In the past few years there has been an increasing number of new issues of shares of common stock together with warrants intended to raise interest in initial public offerings of relatively young, growing firms. In this study we examine the pricing efficiency of stocks and warrants offered simultaneously to the public as a single unit. We present a model for evaluating the warrants in such offerings and test it empirically against data from the Tel-Aviv Stock Exchange, where such offerings have become standard. We find that the issued units are usually undervalued, allowing for significant abnormal positive returns. But, while the warrants are usually underpriced, the stocks are overpriced. Largely consistent with the evidence from other financial markets around the world, we also find abnormal negative rates of return in the long run.     

The Relationship Between Top Management Team–Outside Board Conflict and Outside Board Service Involvement in High‐Tech Start‐Ups

Corporate governance research has extensively studied the relationship between outside board characteristics and outside board involvement. We add to this literature by investigating the extent to which interactions between outside board members and the top management team (TMT) affect the functioning of the outside board. Building on conflict theory, our study shows that conflict between TMT and outside board is an important antecedent for outside board service involvement. Specifically, drawing from a hand‐collected data set of 70 high‐tech start‐ups in Belgium, we find that TMT–outside board task conflict is both directly and indirectly, that is, through TMT–outside board relationship conflict, related to outside board service involvement.     

The value relevance of top executive departures: Evidence from the Netherlands

On theoretical grounds, monitoring of top executives by the (supervisory) board is expected to be value relevant. The empirical evidence is ambiguous and we analyze three non-competing explanations for this ambiguity: (i) The positive effect on firm value of board monitoring is hidden in stock price effects due to the simultaneous occurrence of the positive real effect of monitoring and the opposing information effect. (ii) The combination of board monitoring and monitoring by other parties prevents assessing the value relevance of board monitoring in isolation. (iii) The confounding effect of a simultaneous successor appointment typically generates an upward biased estimate. Based on an analysis of price effects and trading volumes at announcement, we conclude that monitoring by the supervisory board is valued by investors: Forced departures of executive directors, also without a successor appointment, are value relevant in the Netherlands where external control mechanisms and shareholder control were virtually absent in the period studied (1991–2000).     

The effect of noise in a performance measure on work motivation: A real effort laboratory experiment

This paper reports the results of an individual real effort laboratory experiment where subjects are paid for measured performance. Measured performance equals actual performance plus noise. We compare a stable environment where the noise is small with a volatile environment where the noise is large. Subjects exert significantly more effort in the volatile environment than in the stable environment. This finding is in line with standard agency theory and contrasts the intuitive idea captured by a distinct element of expectancy theory that noisier performance measures would lower work motivation.     

Armut in Deutschland – versagt der Sozialstaat?

Empirische Untersuchungen haben nachgewiesen, dass es in Deutschland in einem betr?chtlichen Ausma? Armut gibt. Wie wird Armut definiert? Wie kann man Armut messen? Hat in Deutschland die Ungleichheit der Einkommensverteilung zugenommen? Welche Ma?nahmen müssten ergriffen werden, um Armut zu verhindern? Prof. Dr. Richard Hauser, 70, ist Emeritus des Lehrstuhls für Volkswirtschaftslehre, insbesondere Verteilungs- und Sozialpolitik, an der Johann-Wolfgang-Goethe-Universit?t in Frankfurt am Main. * Vortrag gehalten im Rahmen der Tagung der Akademie für politische Bildung Tutzing in Zusammenarbeit mit dem Studienseminar für Berufliche Schulen in Südbayern zum Thema Umbau oder Abbau – wie viel Zukunft hat der deutsche Sozialstaat? vom 18.-20. Dezember 2006 in Tutzing.
