Abstract
With a sample of farms in the European Union (EU) and Farm Accountancy Data Network (FADN) data completed by additional data, we illustrate how the effect of farm subsidies on technical efficiency changes when environmental (good or bad) outputs are incorporated in the calculation of technical efficiency. Results indicate that the effect of the Common Agricultural Policy (CAP) operational subsidies on farm technical efficiency changes when environmental outputs (in this study: greenhouse gas emissions, nitrogen balance and ecological focus areas) are taken into account in the efficiency calculation: some effects change significance, and more importantly, some effects change sign.
