JERUSALEM — Supporters of a two-state solution to the Israeli-Palestinian conflict generally start with a moral argument: Both peoples deserve the rights of self-determination and sovereignty; one should not rule over the other. Lately, President Obama and liberal American Jewish leaders also frame their case in security terms, saying Israel cannot survive as a Jewish democracy without ending its occupation of Palestinianterritories.

But how about $173 billion as incentive for a peace deal?

That is how much a new report by the RAND Corporation says the Israeli and Palestinian economies stand to gain over the next decade if an independent Palestine were to emerge tomorrow — admittedly a development that might require divine intervention. It translates to an average per capita income increase of $1,000 (36 percent) for every Palestinian in the West Bank and Gaza Strip, and $2,200 (5 percent) for each Israeli.
