Abstract
This article documents employers' expenditure on the arrangements for the health care of their employees in one of the least developed countries; Tanzania. The case for compulsory health insurance is considered in the light of the fact that only 3% of the population is employed in the formal sector and could be covered at first. It is shown from a survey of larger employers, outside government, that they were spending on average 11% of payroll on health care for their employees. This demonstrated their lack of satisfaction with the government health services. Nevertheless, those who could readily be covered by insurance were making considerable use of the more expensive government hospital services. It is argued that a compulsory health insurance scheme could be introduced for the formal sector of employment which would cover a wider range of health services at lower cost. The scheme would also have the desirable economic effect of lowering employers' labour costs while making it possible to improve the standards of the government health services.
