In several recent initial public offerings in privatization cases shares se
emed to be severely underpriced. In this paper we provide a political econo
my explanation for this apparent underpricing. Using a variant of Grossmann
and Helpmann's (1996) model of special interest politics, we demonstrate t
hat governments may raise their election chances by rationing investors bec
ause the resulting broader distribution of shares makes regulation that is
favorable to the privatized firm more popular. Somewhat surprisingly, even
revenues from the privatization can be increased through rationing. The mod
el also explains the common practice of bonus systems designed to prevent i
nvestors from taking profits immediately.
