This book sketches an institutional political economy framework combining developmental state and foreign economic policy literatures to discuss potentials and limits of developmental governance and developmental foreign policy in the global South with reference to Turkey. The authors argue that although the developmental state framework has commonly been employed to explore domestic economic development processes without analytically focusing on foreign policy dimension, developmental state institutions are highly relevant in terms of the creation and pursuit of effective ‘trading state’ policies in a post-liberal international order. The book develops a two-level institutional political economy framework, called ‘regime coherence framework’ (RCF), to account for the domestic and international dimensions of developmental governance in Turkey. The main argument posits that the post-liberal development regime in Turkey and associated foreign economic policies lack coherence, due to poor overlap with ideational, material, and institutional aspects at the domestic-external nexus.
