This paper empirically tests the transaction cost theory by studying the relation between deviations on either side of optimal CEO ownership and firm value. We find that both above-optimal and below-optimal deviations reduce firm value. We find that a change in CEO ownership is associated with a higher (lower) abnormal return if it moves the ownership towards (away from) the optimal level. These findings are consistent with the transaction cost theory of managerial ownership and firm value
