Quality and its impact on efficiency
Daraio, Cinzia; Simar, Léopold; Wilson, Paul W. - 2019
The issue of quality and its relationship with efficiency and performance is a crucial operational issue in many fields of study including production economics, operations research, engineering and business management. In this paper we provide a methodology for identifying latent quality...
