This paper considers the problem of choosing the number of bootstrap repetitions B for bootstrap standard errors … desired level of accuracy. Accuracy is measured by the percentage deviation of the bootstrap standard error estimate …, confidence interval endpoint(s), test's critical value, or test's p-value based on B bootstrap simulations from the corresponding …

We propose a new method of testing stochastic dominance that improves on existing tests based on the standard bootstrap … the variables are allowed to be residuals from nonparametric and semiparametric models. The proposed bootstrap tests have … in general. The improvement stems from the design of the bootstrap test whose limiting behavior mimics the discontinuity …
