“…The working of the EPS is well known and widely analyzed by several authors (e.g. Swimbank and Ritson, 1995;Cioffi and dell'Aquila, 2004;Emlinger, Jacquet and Lozza, 2008;Goetz and Grethe, 2009;Emingler, Lozza and Jacquet, 2010;Garcia, Gomez and Villanueva, 2010;Goetz and Grethe, 2010), but a consensus on its effectiveness is still lacking. Furthermore, while «entry prices for many products are probably not protective, and could readily be abolished» (Swinbank, 2011), it is also likely they produce (still unclear) distortive effects deserving further investigations (Winchester, 2011;Li and Beghin, forthcoming).…”
