Tarımsal Ar-Ge Harcamalarının Tarımsal Toplam Faktör Verimliliği Üzerindeki Etkileri: Seçilmiş Latin Amerika Ülkeleri Örneği

Bu çalışmanın amacı, 1981-2013 döneminde seçilmiş 5 Latin Amerika ülkesini kapsayan tarımsal AR-GE harcamalarının tarımsal toplam faktör verimliliği üzerindeki etkilerini araştırmaktır. Çalışmada yatay kesit bağımlılığı altında panel eşbütünleşme analizi ve tamamen değiştirilmiş en küçük kareler FMOLS yöntemi kullanılmıştır. Çalışmanın sonucunda tarımsal AR-GE harcamaları ile tarımsal toplam faktör verimliliği arasında eşbütünleşme ilişkisi tespit edilmiş olup tarımsal AR-GE harcamalarının esneklik katsayısı 0,58 olarak bulunmuştur

The Impacts of Agricultural Research and Development Expenditures on Agricultural Total Factor Productivity: Evidence from Selected Latin American Countries

The aim of the study is to investigate the impacts of agricultural research and development expenditures on agricultural total factor productivity by using annual panel data set covering 5 selected Latin American countries from 1981 to 2013. In doing so, we use the panel cointegration analysis under cross-section dependence and panel fully modified ordinary least squares FMOLS method. At the end of the analysis; there is a cointegration relationship between research and development and total factor productivity in agriculture sector for these selected countries. Also, the elasticity coefficient of agricultural research and development expenditures is 0.58.
