Descripción
This paper introduces a nonparametric measure of coordination Luenberger productivity growth where the subprocesses are explicitly modelled in the production technology. The coordination productivity indicator is decomposed into a coordination technical inefficiency change component and a coordination technical change component. This decomposition allows to assess how reallocation impacts the different sources of productivity growth. The empirical application focusses on a large panel of English and Welsh farms over the period 2007−2013. The results show that coordination inefficiency significantly increases with the proportion of resources allocated to livestock production in economic and statistical terms. Coordination inefficient farms should generally allocate more land to crop production. Depending on the region, the average coordination Luenberger productivity growth ranges from -9.7 percent to 15.9 percent per year. It is driven by coordination technical change rather than coordination inefficiency change.
