Description The main objectives of this study are to quantify the Total Factor Productivity (TFP) growth
of the durum wheat sector in Tunisia and to identify its main determinants. The Malmquist
index approach was applied for the calculation of TFP growth using one output (annual
production) and four inputs (land, seeds, nitrogen, and phosphate fertilizers) for the period
1980-2012. Variables used to identify the main determinants of the TFP growth include
expenditures on agricultural research and extension, share of irrigated durum wheat area with
respect to its total cultivated area, drought index, and infrastructure development in rural areas.
Almon distributed lag model is used to assess the impact of the research expenditures variable.
Empirical results show that TFP grew with 1.9% per year, in average, during the study period
1980-2012. This average growth rate was highly variable: 5.9% for the period 1980-1991; -
2.2% for the period 1992-2002; and 2.07% for the, period 2003-2012. TFP growth was mainly
generated from technical change during the first period (1980-1991), and from technical
efficiency change during the last period 2003-2012. Results also show that changes in the TFP
growth have been mainly related to the R&D expenditure lags, and drought.
