Weight restrictions in DEA: Misplaced emphasis?

Førsund, Finn R. - 2011

Measuring productive efficiency is an important research strand within fields of economics, management science and … operations research. One definition of efficiency is the proportional scaling needed for observations of an inefficient unit to … weighted inputs. When linear programming is used to estimate efficiency the two definitions give identical results due to the …
