Gains from capital and credit market integration are important sources of mutual benefits that have been neglected in the discussion of the economics of Middle East peace. Such integration entails smoother income and consumption as a result of international diversification of investments. We estimate the magnitude of the potential gains from sharing risk among the countries in the region, finding that they are of considerable magnitude, far exceeding the potential gain from sharing risk among OECD countries. The potential gains are high even for the small 'peace club,' Egypt, Israel, and Jordan. We find that, in practice, the bulk of the smoothing of country-specific output shocks for Middle Eastern countries has been achieved via saving (countries save less in bad years), and to some extent through international transfers. A considerable fraction of the shocks remains not smoothed, suggesting that the gains from further risk sharing through regional financial market integration are substantial.
