Performance Assessment of Two-stage Network Structures in the Presence of Contextual Variables

This research aims to evaluate the eciency of a two-stage network structure by examining the impact of contextual variables on its performance. to accomplish this, a two-stage approach is implemented, which involves network data envelopment analysis (ndea) in the first step and ordinary least squares (ols) analysis in the second step. in the first step, a non-cooperative (leader-follower) model isemployed to assess the eciency of each sub-section within the two-stage process based on their inputs and outputs. in the second step, the logarithm of the estimated eciency scores is regressed on thecontextual variables to refine the network-specific efficiency. the performance of various spanishairports is analyzed to demonstrate the effectiveness of this approach.
