Within an incomplete-information framework. we develop a model of wage dete
rmination in a unionized Cournot oligopoly. The assumption of incomplete in
formation allows the possibility of strikes or lockouts, which waste indust
ry potential resources, at equilibrium. Facing such deadweight loss, the go
vernment or the social planner may decide to adopt a policy, such as a prof
it-sharing scheme. Under two different bargaining structures (firm level vs
. industry level), we investigate the effects of adopting profit sharing on
the wage outcome and the strike activity. If the base-wage bargaining take
s place at the industry level, then the introduction of a profit-sharing sc
heme increases the strike activity. But if the base-wage bargaining takes p
lace at the firm level and the number of firms in the industry is greater t
han two, then the introduction of a profit-sharing scheme reduces the strik
e activity.
