“…Managerial quality is highly associated with firm productivity (Adhvaryu, 2018;Adhvaryu et al, 2018;Bloom and Reenen, 2011;Bloom and Van Reenen, 2007;McKenzie and Woodruff, 2016), including in experimental studies (Bloom et al, 2013(Bloom et al, , 2018bKarlan et al, 2015;McKenzie and Woodruff, 2013). A few recent studies have sought to understand which particular practices matter most, though much work remains to be done in this regard (Bandiera et al, 2017;Bloom et al, 2018aBloom et al, , 2016Campos et al, 2017). We add to this recent strand of work by showing one mechanism through which two important dimensions of managerial quality -monitoring (Bloom et al, 2012;Halac and Prat, 2016) and active personnel management (Aghion et al, 2017;Bresnahan et al, 2002) -generate productivity impacts by mitigating the negative effects of shocks.…”
