In this paper we study the properties of the analytic central path of asemidefinite programming problem under perturbation of a set of inputparameters. Specifically, we analyze the behavior of solutions on the centralpath with respect to changes on the right hand side of the...

Purpose: The purpose of this paper is to estimate the impact of China's outward foreign direct investment (OFDI) conducted by exporting firms on their productivity. Design/methodology/approach: This study uses two Chinese firm-level datasets. To reduce the bias when merging the two datasets,...

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...
