“Asset prices should equal expected discounted cashflows. Forty years ago, Eugene Fama (1970) argued that the expected part, “testing market efficiency,” provided the framework for organizing asset-pricing research in that era. I argue that the “discounted” part better organizes our research today.
I start with facts: how discount rates vary over time and across assets. I turn to theory: why discount rates vary. I attempt a categorization based on central assumptions and links to data, analogous to Fama’s “weak,” “semi-strong,” and “strong” forms of efficiency. Finally, I point to some applications, which I think will be strongly influenced by our new understanding of discount rates. In each case, I have more questions than answers. This paper is more an agenda than a summary.”
