A set of ellipses, with given semi-major and semi-minor axes, is to be cut from a rectangular design plate, while minimizing the area of the design rectangle. The design plate is subject to lower and upper bounds of its widths and lengths; the ellipses are free of any orientation restrictions....

"This paper will introduce new methods to estimate the two-way fixed effects model and the match effects model in datasets where the number of fixed effects makes standard estimation techniques infeasible. The methods work for balanced and unbalanced panels and increase the speed of estimation...

"The IAB Establishment Panel contains no direct information on establishments' capital stock. This report presents some advice in implementing a capital stock approximation by the perpetual inventory method as proposed by Müller (2008). STATA code is provided in the appendix." (Author's...

We propose and axiomatically analyze a class of rational solutions to simple allocation problems where a policy-maker allocates an endowment <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$$E$$</EquationSource> </InlineEquation> among <InlineEquation ID="IEq2"> <EquationSource Format="TEX">$$n$$</EquationSource> </InlineEquation> agents described by a characteristic vector c. We propose a class of recursive rules which mimic a decision process where the...</equationsource></inlineequation></equationsource></inlineequation>
