| Outline of Final Research Achievements |
Our finding is about the possible approximation of non-parametric type approach, which includes data envelopment analysis (DEA), by regression like parametric approaches. When we try to approximate the DEA by usual non-linear production or cost function using Taylor expansion, we cannot obtain a practical and useful approximation of non-parametric frontiers obtained by DEA.
One of the most promising approach seems quantile regression approach. This approach admits the variations in parameters with different quantiles. It seems a promising medium to connect frontier production or cost function to DEA.
