A decision-maker needs to perform a task and can choose whether to do it in period 1, period 2 or period 3. If she does not do it in periods 1 or 2 she is forced to do it in period 3. The cost of performing the task depends on when she does it, where t ∈ {1, 2, 3} indexes the period. The costs are c₁ = 2, c₂ = 4 and c₃ = 8, so c = (2, 4, 8). The benefit of doing it is received in period 4 and is not influenced by when the task is performed. Utility is linear in (discounted) costs and benefits. Denote costs as negative utility. Anna is time-consistent and discounts future costs and benefits exponentially with a discount factor 8 = 1.
