Variance Covariance Orders and Median PreservingSpreads

Malamud, Semyon; Trojani, Fabio - Swiss National Centre of Competence in Research North … - 2009

A random variable dominates another random variable with respectto the covariance order if the covariance of any two monotone increasingfunctions of this variable is smaller. We characterize completely thecovariance order, give strong sufficient conditions for it, present a numberof examples in...

The Risk-Return Paradox for Strategic Management: Disentangling True and Spurious Effects

Henkel, Joachim - 2007

This paper shows that skewness of individual firms return distributions has a considerable spurious effect on the mean-variance relationship as it is usually measured.

Modularity for ValueAppropriation:Drawing the Boundaries ofIntellectual Property

Baldwin, Carliss; Henkel, Joachim - Technische Universität <München> / Schöller Chair in … - 2009

The existing theory of modularity explains how modular designs create value. We extend thistheory to address value appropriation. A product or process design that is modular with respect tointellectual property (IP) allows firms to better capture value in situations where knowledge andvalue...

Quality standards for passenger trains: Political majorities and environmental costs

Rothbauer, Julia; Sieg, Gernot - 2010

This study analyzes the minimum quality standard set by the European Union (EU) through Regulation 1371/2007 of Rail Passengers' Rights and Obligations. A welfare maximizing quality standard raises quality and consumer satisfaction, but does not improve the modal split of rail transport. A...

The role of the prior in estimating VAR models with sign restrictions

Inoue, Atsushi; Kilian, Lutz - 2021

Several recent studies have expressed concern that the Haar prior typically imposed in estimating sign-identified VAR models may be unintentionally informative about the implied prior for the structural impulse responses. This question is indeed important, but we show that the tools that have...

Approximating the Normal Sample Median Distribution in Process Control

Leung, Char - In: Stochastics and Quality Control 36 (2021) 1, pp. 21-25

Abstract The present work aims to propose an approximation of the sample median distribution with a normal parent … distribution. Although the mean is usually used as the central tendency measure for normal samples, the median has also been used … in engineering, process control in particular. The proposed method approximates the normal sample median distribution …
