This study examines whether investors could use Benford's Law as an aid in determining high-risk areas for investing within their process of decision-making. The business reporting standard XBRL offers the opportunity to easily extract and analyze a sufficient number of monetary items out of...

The Generalized Method of Moments (GMM) is discussed for handling the joint occurrence of fixed effects and random measurement errors in an autoregressive panel data model. Finite memory of disturbances, latent regressors and measurement errors is assumed. Two specializations of GMM are...

Wann ist eine Stichprobe repräsentativ? Wie viele Personen müssen befragt, wie viele Messwerte erhoben werden, um repräsentative Ergebnisse zu erzielen? Anhand welcher Verfahren kann die Auswahl der Stichprobenelemente vorgenommen werden? Welche Vor- und Nachteile sind mit dem jeweiligen...

An autoregressive fixed effects panel data equation in error-ridden endogenous and exogenous variables, with finite memory of disturbances, latent regressors and measurement errors is considered. Finite sample properties of GMM estimators are explored by Monte Carlo (MC) simulations. Two kinds...
