The study established one-directional causality that runs from revenue to expenditure (Tax-Spend Hypothesis). This suggests that current government effort at increasing tax revenue is a positive development to reduce or revert the economy from fiscal deficit path. By implication the ongoing government policy towards increase tax revenue and her decision to halt fiscal leakages would sail the economy through the current fiscal crises that are motivated by global crash in the price of crude oil. http://pubs.sciepub.com/jfa/5/3/2/jfa-5-3-2.pdf revenue and expenditure tax-spend hypothesis Nigeria fiscal system
