How the contract model becomes the main mode of purchasing: a combination of evidence and luck in Thailand
Background Paper, 44

Overview
Thailand introduced Social Health Insurance (SHI) for formal sector private employees with the promulgation of the Social Security Act of 1990. The law was published in the Royal Gazette on 1 September 1990, after which there were 180 days for organizational preparation. The 1990 Act nullified the 1954 Social Security Act which was never implemented because of the lack of economic readiness. SHI is a tripartite payroll tax contributory scheme, equally paid for by the employer, employee and the government. The scheme covers four benefits: (1) non-work related sickness, (2) maternity, (3) invalidity and (4) funeral grants. It was initially enforced in all firms having more than 20 employees, but the scheme extended to companies with more than 10 employees after three years.
