This study examines how political and economic factors affect the offer price, share allocation, and other terms governments choose when they privatize state-owned enterprises via a public share offering. Using a 59 country sample of 630 share issue privatizations (SIPs) with total proceeds of over $446 billion during the period 1977-1997, we find that governments consistently underprice SIP offers, tilt their share allocation patterns to favour domestic investors, impose control restrictions on privatized firms, and typically use fixed-price offers rather than book building or competitive tender offers, all to further political and economic policy objectives.
