The costs of not knowing the radius
Rieder, Helmut; Kohl, Matthias; Ruckdeschel, Peter - 2001
We determine the increase of the maximum risk over the minimax risk in the case that the optimally robust estimator for the false radius is used. This is done by numerical solution of the implicit equations which determine optimal robustness, for location, scale, and linear regression models,...

Simultaneous and sequential price competition in heterogeneous duopoly markets : experimental evidence
Kübler, Dorothea; Müller, Wieland - 2001
We investigate simultaneous and sequential price competition in duopoly markets with differentiated products. In both …, just as predicted by the theory, whereas average follower prices are not above average prices in the simultaneous market … simultaneous-move markets whereas first movers do not. As in theory, there is a significant first-mover disadvantage when firms …

Job stability trends and labor market (re-)entry in West Germany 1984 - 1997
Mertens, Antje - 1999
This paper investigates whether job stability in western Germany shows any signs of decline and compares the findings to evidence for the US and the UK. Cross sectional data and calendar information from the German Socioeconomic Panel 1984-1997 are combined allowing to check possible influences...

Implementing efficient market structure
Grimm, Veronika; Riedel, Frank; Wolfstetter, Elmar - 2000
This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clarke-Groves mechanism, characterize the optimal mechanism that maximizes the...
