An economy with two dates is considered, one state at the first date and a finite number of states at the last date. Shareholders determine production plans by voting - one share, one vote - and at-majority stable stock market equilibria, alternative production plans are supported by at mostpercent of the shareholders. It is shown that a-majority stable stock market equilibrium exists ifwhereSis the number of states at the last date andJis the number of firms. Moreover, an example shows that-majority stable stock market equilibria need not exist for smaller's.
