We present a theorem helpful in estimating the mean and variance of a linear function with arbitrary multivariate randomness in its coefficients and variables. We derive a generalized decomposition result from two random linear functions in which the result can be applied to most models using...

We present new empirical evidence for the US economy that inflation reduces the inequality of the earnings distribution. The main mechanism emphasized in this paper is the tax income bracket effect. Governments only adjust the nominal income tax brackets slowly to a rise in prices, typically...
