This paper demonstrates two advantages of well-known block variants of standard algorithms for solving nonlinear systems. First, if a problem is suf­ficiently close to block-diagonal, block algorithms may offer significant speed advantages on a single processor. Second, block Jacobi algorithms...

This paper illustrates some benefits of small-scale distributed processing in solving nearblock-diagonal systems. We review the theoretical advantages of distributed block algorithms and apply such an algorithm to solve a large nonlinear macroeconometric model. For our application, on a...

Coordination of macroeconomic policy has been a major topic at recent summit meetings, and has been the subject of a number of theoretical studies. However, relatively little empirical research exists on policy coordination. This paper is an attempt to help fill this gap. The paper considers the...
