 With regard to management practices, McKenzie, Nicholas Bloom, Aprajit Mahajan and John Roberts argue that the lack of good management practices (e.g.monitoring, target-setting or incentives) and owners' reluctance to delegate decision making to managers constrain the productivity growth of large firms in developing countries.In further research on Indian textile plants, McKenzie, Bloom, Mahajan, Roberts and Benn Eifert find these plants to often still rely on informal management practices because of a mix of lack of both information and competition, but that the adoption of better practices leads to large and sustained gains in productivity.
