|Title:||Productive efficiency of Portuguese vineyard regions|
|Authors:||Costa, Ana Alexandra Vilela Marta Rio|
|Abstract:||The overall globalization in wine industry and the search for sustainability of the sector has increased competition which highlights the importance of productivity gains. The purpose of this paper is to analyse the productive efficiency of the viticulture sector for the Portuguese regions, over the period 1989 to 2007, with data from the EUFADN, using both a deterministic and stochastic approach. The results show an increase of Technical Efficiency (TE) when used the stochastic frontiers analysis (SFA) in all regions, while the data envelopment analysis (DEA) approach through the Malmquist index reveals a stabilization of TE.|
