Analytic Central Path, Sensitivity Analysis and Parametric Linear Programming

Holder, A.G.; Sturm, J.F.; Zhang, S. - Tinbergen Instituut - 1998

In this paper we consider properties of the central path and the analytic center of the optimalface in the context of parametric linear programming. We first show that if the right-hand sidevector of a standard linear program is perturbed, then the analytic center of the optimal face isone-side...

Calculation of Stability Radii for Combinatorial Optimization Problems

Chakravarti, Nilotpal; Wagelmans, Albert P.M. - Tinbergen Instituut - 1997

We present algorithms to calculate the stability radius of optimal or approximate solutions of binary programming problems with a min-sum or min-max objective function. Our algorithms run in polynomial time if the optimization problem itself is polynomially solvable. We also extend our results...

Total Factor Productivity and the Mongolian Transition

Chessa, Antonio G.; Schouwstra, Marije C. - Tinbergen Instituut - 2005

Total Factor Productivity (TFP)is often used on the macro-economic level as an indicator of changes in efficiency of a country. In many transition economies TFP is seen to have been negative the last decade of the plan economy and starts increasing and become positive after a (quite a) few years...

Possibly Ill-behaved Posteriors in Econometric Models

Hoogerheide, Lennart; Dijk, Herman K. van - Tinbergen Instituut - 2008

Highly non-elliptical posterior distributions may occur in several econometric models, in particular, when the likelihood information is allowed to dominate and data information is weak. We explain the issue of highly non-elliptical posteriors in a model for the effect of education on income...
