“…Some recent studies have focused on the efficiency of carbon emission markets (see, for example, Daskalakis and Markellos, 2008;Joyeux and Milunovich, 2010;Charles, Darné and Fouilloux, 2011); determinants of CO 2 allowance prices (see, for example, Alberola et al, 2007Alberola et al, , 2008aChevallier, 2009;Hintermann, 2010;Hitzemann andUhrig-Homburg, 2013 andHammoudeh et al, 2014a,b among many others), comovements of carbon allowance prices and the prices of other financial assets (see, for example, Chevallier, 2011a,b), while other studies have analyzed the relationship between carbon spot and futures prices (see, for example, Uhrig-Homburg and Wagner, 2009;Joyeux and Milunovich, 2010;Chevallier, 2010;Arouri et al, 2012 andRittler, 2012, among others).…”
