The use of general equilibrium models in applied research imposes a di
scipline in which model structures can easily be compared and contrast
ed and model results can be interpreted using a well understood and ri
gorously developed theoretical framework. These features allow researc
hers to compare results across modeling efforts and to build on the ex
perience of others in deriving results and formulating questions. This
paper first presents a brief critical history of applied general equi
librium analysis. It then summarizes the contributions of eight other
papers in this issue.
