"If initial government estimates were optimistic then the plan of building up office space for call centers could be suspect," said Astro del Castillo, managing director of First Grade Holding Inc., a financial management and advisory company in Manila. "The number of jobs will determine the space for offices."
Call center and other providers of outsourced business services will probably create between 500,000 to 600,000 jobs by 2010, short of the one million target set by government, due to competition from other markets, high electricity cost and weakening English proficiency.

Ayala Land, which is spending up to P20 billion in five years to build 5.4 million square feet of offices for call centers, lost 25 centavos, or 1.5 percent, to P16. Ayala Corp., which owns Ayala Land, fell P5, or 0.9 percent, to P540.  AFP
