Medical end-of-life decisions, defined as end-of-life practices with a potential or certain life-shortening effect, precede almost 50% of deaths in Western countries, and receive ample medical-ethical attention. This systematic review aims to detect whether there are differences in the...

Price indices for heterogenous goods such as real estate or fine art constitute crucial information for institutional or private investors considering alternative investments in times of financial markets turmoil. Classical mean-variance analysis of alternative investments has been hampered by...

In multilevel modelling, interest in modeling the nested structure of hierarchical data has been accompanied by increasing attention to different forms of spatial interactions across different levels of the hierarchy. Neglecting such interactions is likely to create problems of inference, which...

We study a random effects censored regression model in the context of repeated games. Introducing a feedback variable into the model leads to violation of the strict exogeneity assumption, thus rendering the random effects estimator inconsistent. Using the example of contributions to a public...

In this paper we investigate households' demand for school meals using a stated preferences approach. Data are collected through phone-structured interviews to 905 residents with children in the German-speaking region of Switzerland during 2007. A Poisson model with random effects is used to...

Based on data from the National Longitudinal Surveys of Youth covering years 2000 through 2008, it is evident that both male and female workers in medium/larger establishments receive not only higher wages but also have a higher probability of participating in benefit programs than those in...

This paper investigates to what extent the persistence of Microsoft Windows in the market for server operating systems is due to lock-in or unobserved preferences. While the hypothesis of lock-in plays an important role in the antitrust policy debate for the operating systems market, it has not...

This paper modifies the Hausman and Taylor (1981) panel data estimator to allow for serial correlation in the remainder disturbances. It demonstrates the gains in efficiency of this estimator versus the standard panel data estimators that ignore serial correlation using Monte Carlo experiments.

The television environment has become increasingly complex over the past decade, but scant attention has been paid to the modeling and forecasting of television ratings. In this study we use a little-known version of the nested logit model that is suitable for aggregate choice decision data,...
