It’s early morning in Karachi, Pakistan’s biggest city, and Muhammad Nasir is outside his makeshift shelter of palm leaves, rags, and bamboo, washing up after breakfast. He uses water stolen from a nearby supply pipe that belongs to the local water utility. The 17-year-old bids farewell to his mother, an unlicensed midwife, and walks to his tire-repair shop, an open-air stand in a residential area with a table of tools and a wooden bench. He checks to make sure the electricity he’s drawing illegally from the overhead power line is on so he can run his tire pump. Then he sends 10-year-old Abid, one of his two employees, along with 12-year-old Irfan, to get tea from a nearby shop.
Nasir’s business, his home, his power and water supply, and even the cup of tea Abid brings him don’t exist in Pakistan’s official figures. They’re part of another economy that doesn’t pay taxes or heed regulations. It probably employs more than three quarters of the nation’s 54 million workers and is worth as much as 50 percent of Pakistan’s 18 trillion rupee ($200 billion) official gross domestic product. And while the documented economy had its smallest expansion in a decade at 2.4 percent in the year ended June 2011, soaring demand for cars, cement for houses, and other goods shows the underground market is thriving.
