Review of matrix computations by Gene H. Golub and Charles F. Van Loan

Howard C. Elman and Gene H. Golub

We perform an analytic and experimental study of line iterative methods for solving linear systems arising from finite difference discretizations of non-self-adjoint elliptic partial differential equations on two-dimensional domains. The methods consist of performing one step of cyclic reduction, followed by solution of the resulting reduced system by line relaxation. We augment previous analys...

Commentary on Selected Papers by Gene Golub on Matrix Factorizations and Applications

UNLEARNING AND DISCOVERY by Charles F. Manski*

I find introspection to be painful. Looking back, I recall doing little of it before age sixteen. Instead, I mainly did the things that I was instructed to do. I studied hard and performed well in courses and examinations, for no deeper reason than that this was what one was supposed to do. As an adult I have introspected when it has seemed constructive to do so, but I still try not to overdo i...

Four Formal(izable) Theories of the Firm?

In this essay, I define and compare elemental versions of four theories of the firm. These elemental theories are distilled from important contributions by Hart, Holmstrom, Klein, Williamson, and others. Although these contributions have been widely cited and much discussed, I have found it difficult to understand the commonalities, distinctions, and potential combinations of these seemingly fa...
