This study examines the response of private consumption and private investment to an exogenous shock of fiscal policy and estimates the size of fiscal multipliers during periods of economic slacks and positive output gap. Panel vector autoregressive (VAR) estimation technique is performed on a sample of 18 Sub‐Saharan African (SSA) countries for the period 2000–2018. The study finds that the output’s fiscal impact multiplier is larger during contractions than during expansion. Furthermore, in contractions, the fiscal multipliers are 0.06% for private consumption and 0.6% for private investment. Meanwhile, in expansions, they are −0.03 for private consumption and −0.04% for private investment. The findings of this study are consistent with the results of previous studies predicting Keynesian views. Thus, to earn sizable, persistent, and long‐lasting effects through fiscal policy, this study recommends that spending programs should account for countercyclical fiscal policy and consider consumption and investment decisions before implementation. Moreover, the fiscal spending interventions tend to target rule‐of‐thumb households and financially constrained firms.
