Correct Answer:
D. All of the above
The Modigliani-Miller (MM) dividend irrelevance theory, proposed by Merton Miller and Franco Modigliani, posits that under certain restrictive assumptions, a company's dividend policy has no effect on its stock price or its cost of capital. This theory suggests that investors are indifferent between receiving dividends and capital gains, as they can create their own 'homemade dividends' by selling a portion of their shares.
- A: Perfect capital markets is a core assumption, implying rational investors, free access to information, no transaction costs, and no arbitrage opportunities.
- B: No taxes is another critical assumption, eliminating any tax differential between dividends and capital gains, which would otherwise influence investor preferences.
- C: No transaction costs means investors can buy or sell shares without incurring brokerage fees or other costs, making homemade dividends perfectly feasible.
- Since the MM dividend irrelevance theory relies on all these highly idealized conditions to hold true, D: All of the above is the correct answer. These assumptions create a theoretical environment where dividend policy becomes irrelevant.
