- Abstract
This paper investigates the determinants of export performance in tea using secondary data spanning from 1970 to 2012. The study utilizes parametric and nonparametric statistics to examine the determinants of export performance. Parametric analysis shows that all variables are non stationary at level and are stationary at first difference. Co integration test using Engle-Granger and Johansen test supported that all variables are co integrated means all variables have long run relationship. In long run coefficients, study reveal that world prices and production quantities are main determinants of tea export performance whereas real exchange rates and dummy variable are not significant. In short run, world prices remain significant determinant of tea export performance while other variables are not. Error correction term has negative sign (-0.721545) which signifies that all variables have long run relationship and adjusting at the speed of 72 percent per annum to correct the disequilibrium amongst the variables. Non parametric statistic test concurred with dummy variables results that trade liberalization has no significant changes in tea export performance. Therefore, tea export performance is mainly determined by internal and external factors as such Tanzanian government should earmark on those factors in order to improve the export performance in Tanzania.
