Already one of the world’s most generous givers, the mayor of New York City has been ramping up his charity in recent years.

Shani, the director general of Israel’s Finance Ministry, was in New York this week on a mission to promote Israel as a center for research and development for the financial services industry with a government program that would include tax breaks and subsidies for US companies.

Israel already is a global leader in the field of high technology, the site of R&D centers for global behemoths such as Intel, IBM, Motorola, Cisco and Hewlett-Packard. All told, some 35,000 Israelis are employed in R&D.
