A new investigative report by Umar Cheema, a reporter for the English-language newspaper "The News", and a founder of the Center for Investigative Reporting in Pakistan, says that just a third of the country's 446 federal lawmakers bothered to file income tax returns last year. One of those who reportedly skipped filing was Pakistan's president, Asif Ali Zardari. "Tax evasion is a social norm in Pakistan," says Umar Cheema. Tax evasion is a chronic problem in Pakistan - only about 2 percent of the population is registered in the tax system, and the government collects just 9 percent of the country's wealth in taxes, one of the lowest rates in the world." In economic theory there are five important problems that institutions can help to solve. The fact that so many people are involved in tax evasion in Pakistan can be related to one of the institutional problems. In development economics this problem is called coordination problem. This means that Question 17 options: A) Individuals follow their self-interest in making their choices no matter what others are doing B) Individual's choice depends on the choice of others C) People are not well educated and do not know how to file
