This page contains GAMS programs which utilize the GAMS/DEA solver. Using this solver for a DEA problem which has a large number of observations can be extremely beneficial because of the savings in computation time. It can also be used to bootstrap DEA models. These routines require the CPLEX solver: if it is not part of your GAMS license, you will not be able to use the DEA solver.

The programs below show how to use the DEA solver to bootstrap an output oriented technical efficiency model. The citation for this model is: Walden, J.B. 2006. "Estimating vessel efficiency using a bootstrapped Data Envelopment Analysis model."Marine Resource Economics, 21(2): 181-192.

The following .ZIP file includes: the set-up for programming an output oriented technical efficiency model, programs needed to bootstrap the results, and programs used to construct confidence intervals around the estimates. These files can be downloaded here.
