“…Previous publications on the provision of control reserve were made by the author of this doctoral thesis on several occasions (e.g. (Brauns et al, 2014;Hennig et al, 2014;Jansen, 2014, Jansen & Speckmann, 2013a, 2013bJansen, Speckmann, Harpe et al, 2013;Rohrig et al, 2013) Source: Own analysis based on (Andersen et al, 2012;Braun, 2009;Consentec, 2011;Consentec et al, 2011;Frunt et al, 2009;Gesino, 2011;Kapetanovic et al, 2008;Kirby et al, 2010;Morales et al, 2010;Papaefthymiou et al, 2015;Pinson, 2006;Pinson et al, 2007;Saiz-Marin, GarciaGonzalez et al, 2012;Speckmann, 2016;Tuohy et al, 2012;Zhang et al, 2013;Zugno et al, 2010) (Spitalny et al, 2012, p. 5).
