The cost of Israeli occupation? $2.5 billion a year for Palestinians
The figure included $28 billion in accrued interest and $6.6 billion in leakage from Palestinian fiscal revenues.
It said the amount would have been enough to eliminate the Palestinian government's $17.7 billion budget deficit over the same period more than twice over.
The report argued if the $47 billion had been invested sensibly in the impoverished Palestinian economy, it would have created an extra two million jobs over the 18-year period, or 110,000 a year.
The report was presented at the Palestine Economic Policy Research Institute (MAS) in the West Bank city of Ramallah, home to the Palestinian government.
Misyef Jameel, senior researcher at MAS who worked on the report, said they only measured the direct fiscal impact.
The real figure for all losses was likely much higher, he said.
The market area is on Hebron's Shuhada Street.
