Risk and performance estimation in hedge funds revisited: Evidence from errors in variables

This paper revisits the performance of hedge funds in the presence of errors in variables. To reduce the bias induced by measurement error, we introduce an estimator based on cross sample moments of orders three and four. This Higher Moment Estimation (HME) technique has significant consequences on the measure of factor loadings and the estimation of abnormal performance. Large changes in alphas can be attributed to measurement errors at the level of explanatory variables, while we emphasize some shifts in the economic contents of the equity risk premiums by switching from OLS to HME.     

Strategic reward systems: a contingency model of pay system design

A limited number of studies have addressed the idea of ‘strategic’ reward systems—the matching of compensation systems to a firm's strategy. Prior research on this topic has been confined to U.S. firms, however, and a number of key questions remain unanswered. Using a sample of 917 employees from two large Swiss financial institutions, we found that pay systems are linked with divisional strategic orientation, but in a different form than prior studies. Additionally, we identify hierarchical position as an important variable in the tailoring of reward systems. Hierarchy has a significant main effect on pay plan design, and an interactive effect with strategic orientation. Copyright © 2001 John Wiley & Sons, Ltd.     

Once were farmers: Occupation, social mobility, and mortality during industrialization in Saguenay-Lac-Saint-Jean, Quebec 1840–1971

We study men's adult mortality and longevity by socio-occupational status during industrialization in Saguenay-Lac-Saint-Jean, Quebec. Data were extracted from the BALSAC database (Université du Québec à Chicoutimi), which comprehensively traces the demographic history of the region since the beginning of the French Canadian settlement in 1840 up to the early 1970s. Using five occupational classes and controlling for year, age at marriage, urban/rural residence, and literacy, we found no evidence for the emergence of a socioeconomic gradient in mortality. At least until the early 1970s, mortality in the region is the lowest for farmers and appears to be driven by occupational risk rather than fundamental social causes.     

Common cyclical features analysis in VAR models with cointegration

The paper considers n-dimensional VAR models for variables exhibiting cointegration and common cyclical features. Two specific reduced rank vector error correction models are discussed. In one, named the “strong form” and denoted by SF, the collection of all coefficient matrices of a VECM has rank less than n, in the other, named the “weak form” and denoted by WF, the collection of all coefficient matrices except the matrix of coefficient of error correction terms has rank less than n. The paper explores the theoretical connections between these two forms, suggests asymptotic tests for each form and examines the small sample properties of these tests by Monte Carlo simulations.     

ATTAINABLE CLAIMS IN A MARKOV MARKET1

It is shown how, even when the market is incomplete, certain contingent claims are attainable: that is, they can be represented as stochastic integrals with respect to the process which describes the evolution of the asset prices.     

Asymptotic behavior and optimal properties of a consumption-investment model with variable time preference

This paper analyzes the convergence properties and the determination of an optimal consumption path in the consumption-investment model of Uzawa (1968). Sufficient conditions for the existence and uniqueness of the optimal path are presented. Components of the utility functional are recovered when the optimal path is piecewise affine. The model is applied to the determination of the interest rate and income distribution under time preference differentials.     

Compulsive buying: Concept and measurement

This article investigates the probable causes of compulsive buying, proposes a conceptual framework to explain the phenomenon, and develops an appropriate measuring scale. The results of the analysis testify to the reliability and validity of the scale which was administered to 76 consumers.

Begriffliche und empirische Erfassung von zwanghaftem Kaufverhalten

Zusammenfassung Der Beitrag behandelt zwanghaftes Kaufverhalten als einen besonderen Verhaltenstyp, der aus dem Zusammenwirken dreier Kräfte erklärt wird, nämlich erstens einer starken emotionalen Aktivierung, zweitens einer hohen kognitiven Kontrolle und drittens einer hohen Reaktivität. Der wichtigste Unterschied zwischen zwanghaftem und impulsivem Kaufverhalten wird in den kognitiven Vorgängen gesehen, die eine Person dazu führen, die Wiedererlangung des affektiven Gleichgewichtes mit einem Kaufakt zu assoziieren. Genauere Unterschiede zwischen verschiedenen Kaufverhaltenstypen bietet Figur 1. Die Zusammenhänge, die zur Entstehung von zwanghaftem Kaufverhalten führen, werden in Figur 2 gezeigt. Aus diesen Zusammenhängen ergeben sich drei Hypothesen, die empirisch geprüft werden:1. Der zwanghafte Käufer ist im allgemeinen in höherem Maße ängstlich als ein durchschnittlicher Käufer. 2. Der zwanghafte Käufer hat tendenziell ein schwächeres Selbstbewußtsein. 3. Der zwanghafte Verbraucher hat häufiger ein Elternteil mit mißbräuchlichem Verbraucherverhalten.Zur Prüfung dieser Hypothesen wird eine Skala entwickelt, die in Tabelle I beschrieben ist und deren Reliabilität und Validität sich als befriedigend erweist. Außerdem dürfte sie eindimensional sein. Die Daten, die von 38 zwanghaften Käufern und einer gleichgroßen Zahl von durchschnittlichen Käufern stammen, stützen die erste und die dritte Hypothese, die zweite Hypothese konnte nicht bestätigt werden.
