The impact of public investment spending on the external balance in Algeria, an analytical standard study for the period 1990-2018 using the ARDL model

Abstract

This study aims to measure the impact of public investment spending on the
external balance in Algeria during the period 1990-2018 by reviewing the evolution of
balance of payments balances, public investment spending, oil revenues and budget balance,
and by relying on economic measurement methods by examining the stability of time series
by applying the Dickey test - Fuller and Phillips-Perron, and the use of the boundary test to
detect the existence of co-integration between variables and estimate the relationship between
them in the short and long run using the Autoregressive Model of Decelerated Distributed
Time Gaps (ARDL), where the obtained results revealed that public investment spending
positively affects the external balance in the run short and long term.
