This paper provides a review of some connecting literature in Decision Sciences, Economics,
Finance, Business, Computing, and Big Data. We then discuss some research that is related to the
six cognate disciplines. Academics could develop theoretical models and subsequent econometric
and statistical models to estimate the parameters in the associated models. Moreover, they could
then conduct simulations to examine whether the estimators or statistics in the new theories on
estimation and hypothesis have small size and high power. Thereafter, academics and practitioners
could then apply their theories to analyze interesting problems and issues in the six disciplines and
other cognate areas
