Firms may face nancing constraints as a result of rational behaviour of potential lenders due to asymmetric information. In this article, a theoretical model of employment adjustment is developed to derive hypotheses on the short-run impact of nancing constraints on employment at the rm level. A unique rm panel data set for German manufacturing is used to assess the empirical evidence for this ...

The well known conjugate gradient algorithm (cg-algorithm), introduced by Hestenes & Stiefel, [1952] intended for real, symmetric, positive definite matrices works as well for complex matrices and has the same typical convergence behavior. It will also work, not generally, but in many cases for hermitean, but not necessarily positive definite matrices. We shall show, that the same behavior is s...
