We use tools from the theory of large deviations to show that wishful thinking decision problems are equivalent to utility maximization problems, both of which are equivalent to growth maximization under idiosyncratic risk. Rational inattention problems are equivalent to growth-optimal portfolio problems, both of which are equivalent to growth maximization under aggregate risk. Stochastic growth generates extreme inequality, with nearly all wealth eventually held by those who happen to have faced empirical distributions that match the solution to the wishful thinking or rational inattention problem.

In our model, financial constraints and the dispersion of MRPK persist, and even large firms are likely to be constrained. The productivity loss from financial frictions is also substantially amplified.

We find that remote instruction was a primary driver of the widening gaps. Math gaps did not widen in areas that remained in person (although reading gaps did). We estimate that high-poverty districts that went remote in 2020–2021 will need to spend nearly all of their federal aid on helping students recover from pandemic-related academic achievement losses.
