This paper proposes a mixed-frequency error-correction model in order to develop a regressionapproach for non-stationary variables sampled at different frequencies that are possiblycointegrated. We show that, at the model representation level, the choice of the timing betweenthe low-frequency...

It is well known that cointegration between the level of two variables (labeled Y_{t} and y_{t} inthis paper) is a necessary condition to assess the empirical validity of a present-value model (PVand PVM, respectively, hereafter) linking them. The work on cointegration has been so prevalentthat...

Using a reduced rank regression framework as well as information criteria we investigate the presence of commonalities in the intraday periodicity, a dominant feature in the return volatility of most intraday financial time series. We find that the test has little size distortion and reasonable...

First, we investigate the minimal univariate representation of some well known n dimensional conditional volatility models. Simple systems (e.g. a VEC(0,1)) for the joint behaviour of several variables imply individual processes with a lot of persistence in the form of long order lags. We show...

In spite of the increased use of factor-augmented regressions in recent years, little is knownregarding the relative merits of the two main approaches to estimation and inference, namely, thecross-sectional average and principal components estimators. As a response to this, the currentpaper...

This article builds on the call of various authors (e.g. George & Jones, 2000; Mitchell & James,2001; Rousseau & Fried, 2001) for a better representation of time in theory-building andresearch in organizational behavior (OB). It proposes a radical temporalist approach to the study of OB which combines a...

Under a k-approval scoring rule each agent attaches a score of one to his k most preferred alternatives and zero to the other alternatives. The rule assigns the set of alternatives with maximal score. Agents may extend preferences to sets in several ways: they may compare the worst alternatives,...

Competition in the emerging multimedia market currently focuses on setting standards for storing, retrieving, processing, (de)compressing, and transmitting information. Each multimedia system or architecture combines several standards, some proprietary. This paper uses selected insights from...

This paper investigates exceptional phases of stock market cycles. Defined in Pagan and Sossounov (2003) as unusual, they are detected as outliers in the historical distribution. Moreover, this study completes the growing literature on stock market bulls and bears in several aspects. First,it...

Co-determination refers to a set of rules and institutions which form an interlocking system and as such provide the unique structure of German corporate governance. This essay deals with the reasons responsible for bringing the structure about. In particular, the decision making process leading...
