The Analysis of the Domestic and International R&D Impact of Agricultural TFP in Iran
Subject Areas : Labor and Demographic Economics
Keywords: TFP, Divisia Index, Agricultural R&D,
Abstract :
Abstract This study measures the total factor productivity in the agriculture of Iran and analyzes the relationship between TFP, domestic agricultural research, human capital and foreign agricultural R&D during 1979 – 2008. The Divisia index approach is applied for the measurement of total factor productivity in Iran agriculture. Almon distributed lag model involving different lag length specifications will be estimated taking TFP as a dependent variable. The results indicate that agricultural researches (both domestic and foreign R&D) have positive and significant impact on TFP in agricultural sector.
