In the 'size of stakes' view quantitatively formalised in Gabaix and Landier (2008) Executive compensation remains very much at the center-stage of academic and policy debates. A relative lack of consensus seems to prevail regarding the origins of the large rise of executive compensation observed in the US since the 70s. According to some scholars (see e.g. Bebchuck and Fried (2004) for a summary of this view), rising compensation is due to a higher ability of CEOs to extract rents from shareholders, e.g. by capturing their board (Shivdasani and Yermack, 1999) or appointing compensation consultants that cater to their interests (Murphy and Sandino, 2010). Hermalin (2005) argues instead that the rise in CEO pay reflects tighter corporate governance: pay increases to compensate CEOs for the greater risk of being fired. Others argue that the very function of CEOs has changed over time: they are now more often poached from outside firms than before (Murphy and Zabojnik, 2004;Frydman, 2005); shareholders have become more convinced of the importance of financial incentives (Jensen et al., 2004). By contrast, Gabaix and Landier (2008, henceforth GL) argue that the bulk of variations in CEO compensation across time and across companies can be explained as the result of competitive market forces. They show that under fairly general assumptions, in a market,
