Impact of diversification on technical efficiency of organic farming in Switzerland, Austria and Southern Germany
Lakner, Sebastian; Kirchweger, Stefan; Hoop, Daniel; … - 2015
The paper investigates the impact of subsidies and of para-agriculture on the technical efficiency of organic farms in Switzerland, Austria and Southern Germany. The data-set consists of bookkeeping data with 1,704 observations in the years 2003 to 2005. Technical efficiency is modelled using a...
