“…The mainstream of research using nonparametric methods to assess the efficiency of agricultural production includes studies such as (Baran, 2009), which focuses on the efficiency of dairy cooperatives in Poland. Other examples include (Burja, 2011), a study focusing on Romanian agriculture; (Zimmermann and Heckelei, 2012), a report on European dairy farms; (Akande, 2012), an analysis of FADN regions; and (Atici, 2012), an article on Turkish agriculture. Moreover, (Baležentis and Valkauskas, 2013) examines the efficiency of selected farms in Lithuania; (Brummer and Thiele, 1999) looks at ways of studying aggregated efficiency on the basis of data on German farms; (Buckley and Carney, 2013) focuses on the analysis of efficiency in Irish agriculture; (Błażejczyk-Majka et al, 2011Špička, 2014) look at FADN regions; and (Smędzik, 2010) focuses on Polish farms.…”
