The recent decrease in U.S. money velocity raises debates about its unit root behavior. This paper revisited the random walk hypothesis (RWH) of the U.S. money velocity in 1960-2010 and two sub-periods 1960-85 and 1986-2010 by applying the Variance Ratio methodologies, including new nonparametric tests by Wright (2000) and Belaire-Franch and Contreras (2004). The results suggested that the velocity would likely increase, and the U.S. monetary policy will soon stimulate GDP and employment. Furthermore, past velocity is important to predict the future outcomes, and changes in financial structural could alter the empirical characteristics of the velocity series.
