Alternative algorithms for computing economic equilibria

This paper reports on numerical experience in solving, general equilibrium problems using several alternative solution methods. The primary concern is to help identify methods which may be practical for solving large-scale problems. The methods examined include: sequences of linear programs, piecewise-linear homotopy methods, quasi-Newton methods for optimization, and sequences of linear complementarity problems. This work indicates that computing equilibria by sequences of linear complementarity problems is quite efficient for large problems.
