This paper is about the relation between output and productivity measures for individual production units and those for aggregates such as industries, sectors, or economies. In the framework of discrete timeperiods several useful expressions are derived and confronted with results from the...

It is well known that, in continuous time, the Cobb-Douglas function can be derived from the underlying, data governing, accounting identity under some reasonable assumptions (factor shares are constant, and the weighted growth of the labour input price and the capital input price is constant)....

Total Factor Productivity Toolbox is a new package for MATLAB that includes functions to calculate the main Total Factor Productivity (TFP) indices and their decompositions, based on Shephard's distance functions and using Data Envelopment Analysis (DEA) programming techniques. The package...

Total factor productivity change, here defined as output quantity change divided by input quantity change, is the combined result of (technical) efficiency change, technological change, a scale effect, and input and output mix effects. Sometimes allocative efficiency change is supposed to also...
