Testing correlation in the long run between production account and exploitation account variables To the agriculture sector in Algeria (Co-integration approach and model error correction during the period from 1974 to 2012)

Abstract

 This paper examines the existence of the relationship in the long run between production account and exploitation account variables To the agriculture sector in Algeria; was chosen as the agriculture sector variables because of its importance in achieving food security, diversifying sources of national income, We applied co-integration approach and model error correction on the variables the study during the period between 1974-2012, Through a qualitative statistical tests ; Charts and graphics autocorrelation function, test function autocorrelation coefficients P_k and test Ljung-Box, and also the results of quantitative tests represented in the DF test, ADF test, PP test, test KPSS, Co-integration test, and the most important findings of the study, there is a cointégration relationship between the variables of the study in a long run
