Abstract
This paper identifies a new corporate governance mechanism: sharing control. We show
that bargaining problems among multiple controlling shareholders may prevent inefficient
investment decisions that harm minority shareholders. The same bargaining problems may
block efficient investment decisions, though. By solving this trade-off, we show that the
likelihood that shared control is efficient increases with three firm characteristics: over-
investment problems, the cost of verifying cash flows, and financing requirements. The
model provides testable implications for the role that large shareholders play in corporate
governance, contrasting shared control and monitoring as alternative governance mecha-
nisms.
jel: G30, G34, G32. keywords: Sharing of control, corporate governance, monitoring,
investment decisions.

This table shows the fraction of the 303 Italian public firms with shareholders’ agreements, as reported by
the “Ownership Structure of Companies Listed on Stock Exchanges in Italy,” CONSOB, December 1996.
Buy-out agreements impose restrictions on the transferability of shares. Voting (or pooling) agreements force
the participants of the agreement to vote with the group. Control agreements set corporate policies that
otherwise would be decided by the board of directors. Any agreement refers to firms that have any of the
previously mentioned shareholders’ agreements. Numbers in parenthesis show the percentage of the 303
public firms that have the agreements.

The NSSBF database includes 4,637 firms with less than 500 employees that answered the 1992 National
Survey of Small Business Finances. Out of these 4,637 firms we extracted the close corporations with more
than one shareholder and annual sales above $10 million, ending up with our full sample of 310 firms.
Manager-Owned Firms excludes firms where the manager is not a shareholder, while Non-Manager-Owned
Firms includes only firms where the manager is not a shareholder. Observations give the number of firms in
each sub-sample. Number of firms gives the NSSBF estimate of the number of firms that each sub-sample
would have if all firms had answered the survey. For the estimated number of firms of each sub-sample,
Average number of employees, Average asset value ($ million), and Average annual sales ($ million) give,
respectively, the average number of employees, and the average book value of assets and annual sales in
millions of dollars. Median (Average) number of shareholders is the median (average) number of
shareholders of the estimated number of firms in each sub-sample. Number of firms (condition)- % is the
fraction of the estimated number of firms satisfying the (condition) over the estimated number of firm in
each sub-sample in percentage terms. A firm is said to have multiple large shareholders if two shareholders
have at least 10% of the shares and one of them has more than 20%. A firm has one large shareholder if at
least one shareholder has more than 20% of the shares while the other shareholders have less than 10% of
the shares. A firm has minority shareholders if there are no large shareholders or if there is a shareholder
with less than half of the shares of a large shareholder.
