A number of studies on the role of agricultural sector in the economic growth and contribution of different sectors have been conducted in developing and developed countries. But this study describes the application of a four-sector numerical simulation model of economic growth in Palestine, yielding macroeconomic growth multipliers which complement the regional growth linkage literature also. Palestinian agriculture has a central role to play in Palestinian economic growth. Intersectoral growth multipliers favor agriculture over industry as a source of macroeconomic income generation. Palestinian governments seeking to promote economic growth cannot afford to ignore agriculture in the design of their growth strategies.
