Productivity change analysis in dairy farms following Polish accession to the EU – An output growth decomposition approach

The aim of this study was to assess changes in productivity of dairy farms after Poland’s accession to the European Union using a new decomposition of output growth within a stochastic frontier framework. We demonstrate how changes in economies of scale can be isolated, which leads to redefined components of output growth and a better measure of productivity growth. The productivity component is disaggregated to its three generic sources: total...
