Mixed markets in bilateral monopoly

Should we expect to see patterns in the privatization of a public bilateral monopoly? To address this question, the paper analyzes the welfare implications of privatization and examines the interplay of firm location in the vertical stream, differential priorities on private and public profit in welfare and cost asymmetries in a mixed bilateral monopoly. We conclude that merely comparing cost savings from privatization upstream/downstream, is inadequate. If public profit is relatively insignificant in welfare, then only relative cost savings matter. However, if public profit is sufficiently important, then privatization downstream will maximize welfare if it is as (or more) cost effective compared to privatization upstream. We find that downstream privatization can be better than upstream privatization even when the latter is more cost effective than the former.
