Malmquist Index
Malmquist indices measure productivity change over time at DMU level. They are decomposed into Efficiency Catch Up and Boundary Shift (Technical Change), components.
To compute the Malmquist Indices you need a balanced panel of data of at least two time periods. Under the 'Malmquist' heading shown above you will need to select one of the two decompositions available.
The Malmquist index is computed under constant returns to scale. If you then opt for the FGNZ Option, the decomposition yields the shift of the CRS boundary (Fare et al. 1994). If you specify VRS technology under General above you may opt for the (Ray & Desli 1997) decomposition where the boundary shift relates to the VRS boundary.
