Splet05. maj 2014 · The Law of Iterated Expectations (or the Tower Property), is a very useful -and very intuitive- result: Or, "the smaller information set always prevails". Of course the … SpletBy using the law of iterated expectation we can show the last term in (8) is zero conditional on X; x f(X) behaves like a constant (both being functions of X), and we already proved in …

Splet11. For a similar game-theoretic approach concerning tax evasion, see Reinganum and Wilde (1986) and Graetz, Reinganum, and Wilde (1986). Their approach is similar because they model tax compliance as a game between the public and the IRS but differs from mine because they focus on a sequential game, where the public moves first by filing a tax …
