“…The impact of milk quotas on the farm level is complex (Huettel and Jongeneel, 2011), but milk quotas are likely to hamper changes on dairy farms (Piet et al, 2012). Existing research on the influence of milk quotas includes the impact on changes in farm size (Breustedt and Glauben, 2007;Huettel and Jongeneel, 2011;Zimmermann and Heckelei, 2012), production (Ooms and Peerlings, 2005;Breustedt and Glauben, 2007;Huettel and Jongeneel, 2011), farm characteristics (Gale, 2003;Ooms and Peerlings, 2005;Huettel and Jongeneel, 2011), market conditions, land mobility (Harrington, 1995) or a combination of them (Zimmermann and Heckelei, 2012).…”
