In the Michaelis-Menten model we determine efficient designs by maximizing a minimum of standardized E-efficiencies. It is shown that in many cases the optimal designs are supported at only two points and the support points and corresponding weights can be characterized explicitly. Moreover, a...

Several estimators of the expectation, median and mode of the lognormal distribution are derived. They aim to be approximately unbiased, efficient, or have a minimax property in the class of estimators we introduce. The small-sample properties of these estimators are assessed by simulations and,...

In this study we use hedonic models to measure the influence of noise nuisance on rents, costs and values of investment properties in Switzerland. Countrywide data is provided by institutional real estate investors. The effects are measured for aircraft noise, road traffic noise and railroad...
