We exploit the key longitudinal feature of our data to measure and control for preprivatization selection bias and to estimate long-run impacts. We find that the magnitudes of our estimates are robust to alternative functional forms, but sensitive to how we control for selection. Our preferred random growth models imply that majority privatization raises MFP about 15% in Romania, 8% in Hungary, and 2% in Ukraine, while in Russia it lowers it 3%. Privatization to foreign rather than domestic investors has a larger impact, 18-35%, in all countries. Positive domestic effects appear within a year in Hungary, Romania, and Ukraine and continue growing thereafter, but take 5 years after privatization to emerge in Russia.

We examine the impact of o wnership concentration on firm performance using panel data for firms listed on the Budapest Stock Exchange, where ownership tends to be highly concentrated and frequently involves multiple blocks. Fixed-effects estimates imply that the size of the largest block increases profitability and efficiency strongly and monotonically, but the effects of total blockholdings are much smaller and statistically insignificant. Controlling for the size of the largest block, point estimates of the marginal effects of additional blocks are negative. The results suggest that the marginal costs of concentration may outweigh the benefits when the increased concentration involves "too many cooks."
