The following post comes to us from Sreedhar Bharath of the Department of Finance at Arizona State University, Amy Dittmar of the Department of Finance at the University of Michigan, and Jagadeesh Sivadasan of the Department of Business Economics and Public Policy at the University of Michigan.
Are private firms more efficient than public firms? Jensen (1986) suggests that going-private could result in efficiency gains by aligning managers’ incentives with shareholders and providing better monitoring. In our paper, Do Going-Private Transactions Affect Plant Efficiency and Investment?, forthcoming in the Review of Financial Studies, we examine a broad dataset of going-private transactions, including those taken private by private equity, management and private operating firms between 1981 and 2005. We link data on going-private transactions to rich plant-level US Census microdata to examine how going-private affects plant-level productivity, investment, and exit (sale and closure). While we find within-plant increases in measures of productivity after going-private, there is little evidence of efficiency gains relative to a control sample composed of firms from within the same industry, and of similar age and size (employment) as the going-private firms. Further, our productivity results hold excluding all plants that underwent a change in ownership after going-private, alleviating the potential concern that control plants may undergo improvements through ownership changes.
