Ein fehlerhaftes Testat führt oft zur Überbewertung des Unternehmens. Auf dem Sekundärmarkt, d.h. bei der Abschlussprüfung eines bereits börsennotierten Unternehmens, weiß ein uninformierter Anleger ex-ante nicht, ob er Käufer oder Verkäufer überteuerter Aktien sein wird. Er kann einen...

Anti-Sharing may solve the sharing problem of teams: the team members promise a fixed payment to the Anti-Sharer. He collects the actual output and pays out its value to them. We prove that the internal Anti- Sharer is unproductive in equilibrium.

Die Ökonomische Analyse des Rechts umweht in Deutschland immer noch der Hauch des Exotischen. In diesem Beitrag soll begründet werden, warum das ökonomische Entscheidungsmodell ganz hervorragend dazu geeignet ist, die Verhaltensfolgen von Gesetzen zu prognostizieren. Deshalb kann die ÖAR...

Judicial Independence is a crucial aspect of the rule of law and the concept of separation of powers. It gives judges considerable leeway in interpreting and thereby modifying the constitution. In this paper, the role of the European Court of Justice (ECJ) as an actor in the strategic game...

In diagnostic medicine, there is great interest in developing strategies for combining biomarkers in order to optimize classification accuracy. A popular model that has been used for receiver operating characteristic (ROC) curve modelling when one biomarker is available is the binormal model....

One of the benefits of profiling of cancer samples using microarrays is the generation of molecular fingerprints that will define subtypes of disease. Such subgroups have typically been found in microarray data using hierarchical clustering. A major problem in interpretation of the output is...

Suppose that inference about parameters of interest is to be based on an unbiased estimating function that is U-statistic of degree 1 or 2. We define suitable studentized versions of such estimating functions and consider asymptotic approximations as well as an estimating function bootstrap...

Randomized allocation of treatments is a cornerstone of experimental design, but has drawbacks when a limited set of individuals are willing to be randomized, or the act of randomization undermines the success of the treatment. Choice-based experimental designs allow a subset of the participants...

We propose and compare two approaches for regression analysis of multilevel binary data when clusters are not necessarily nested: a GEE method that relies on a working independence assumption coupled with a three-step method for obtaining empirical standard errors; and a likelihood-based method...

In medical studies, it is often of interest to characterize the relationship between a time-to-event and covariates, not only time-independent but also time-dependent. Time-dependent covariates are generally measured intermittently and with error. Recent interests focus on the proportional...
