Suppose that there are just three types of investors with the following tax rates:

	Individuals				Corporations				Institutions
Dividends		45	%			20	%				0	%
Capital gains		16				6					0

Individuals invest a total of $80.7 billion in stock and corporations invest $10.84 billion. The remaining stock is held by the institutions. All three groups simply seek to maximize their after-tax income.

These investors can choose from three types of stock offering the following pretax payouts per share:

	Low Payout				Medium Payout				High Payout
Dividends		$	6			$	6			$	35
Capital gains			16				6				0

These payoffs are expected to persist in perpetuity. The low-payout stocks have a total market value of $100.7 billion, the medium-payout stocks have a value of $50.7 billion, and the high-payout stocks have a value of $120.7 billion.

a. Who are the marginal investors that determine the prices of the stocks?

	Institutions
	Individuals
	Corporations
