 This paper proposes a general framework for inference on three types of almost dominances: Almost Lorenz, almost inverse stochastic, and almost stochastic dominances.
We first generalize almost Lorenz dominance to almost upward and downward Lorenz dominances. We then provide an inference procedure for the Lorenz dominance coefficients, which measure the degrees of almost Lorenz dominances. Furthermore, we propose almost upward and downward inverse stochastic dominances and provide inference on the inverse stochastic dominance coefficients. We also show that our results can easily be extended to almost stochastic dominance. Simulation studies demonstrate the finite sample properties of the proposed estimators and the bootstrap confidence intervals. We apply our methods to the inequality growth in the United Kingdom and find evidence for almost upward inverse stochastic dominance.
