This is the first report to systematically evaluate and quantify the economic potential of Area C, which constitutes approximately 61 percent of the West Bank. The report reveals that lifting the restrictions on economic activity in Area C could have a large positive impact on Palestinian GDP, public finances, and employment prospects. Among other things, access to economic activity in Area C is expected to be a key prerequisite for building a sustainable Palestinian economy. However, full potential of the Area C could be materialised only if other restrictions on free movement of goods, labour and capital are removed and the overall business environment in Palestinian territories has become more attractive. The economic significance of Area C lies in that it is the only contiguous territory in the West Bank, which renders it indispensable to connective infrastructure development across the West Bank, and a relative abundance of natural resources situated therein. Area C offers large potential for the development of several sectors of the Palestinian economy: agriculture, stone and mineral processing, cosmetics, construction, tourism, and telecommunications. The report shows that access to economic activity in Area C could increase the Palestinian GDP by as much as 35 percent, the majority of this impact would stem from agriculture and Dead Sea minerals processing industries, as well as the multiplier effect, which has been estimated at 1.5. Although the importance of building connective infrastructure through Area C is discussed in the report, the quantification of this impact is beyond the scope of this report. An increase in GDP of 35 percent, although thought to be a conservative estimate, would be expected to result in at least $800 million increase in tax revenues for the Palestinian authority, which would drastically reduce its dependence on donor aid for financing chronic budget deficits.
