Test results based on quarterly time series data spanning the period (1960 -2010) shows deviations from equilibrium in fixed private investment growth tend to be corrected relatively faster than this study expected. This study also finds significant long-run and causal relationships between macroeconomic uncertainty, consumer sentiments, growth in consumption expenditures, and US fixed private investment growth.
