As part of the background research to the World development report 1993: investing in health, an effort was made to estimate public, private and total expenditures on health for all countries of the world. Estimates could be found for public spending for most countries, but for private expenditure in many fewer countries. Regressions were used to predict the missing values of regional and global estimates. These econometric exercises were also used to relate expenditure to measures of health status. In 1990 the world spent an estimated US$ 1.7 trillion (1.7 x 10(12) on health, or $1.9 trillion (1.9 x 10(12)) in dollars adjusted for higher purchasing power in poorer countries. This amount was about 60% public and 40% private in origin. However, as incomes rise, public health expenditure tends to displace private spending and to account for the increasing share of incomes devoted to health.
作为《1993年世界发展报告：投资于健康》背景研究的一部分，人们努力估算世界各国的公共、私人及卫生总支出。多数国家的公共支出估算可得，但私人支出估算仅在较少国家能够找到。采用回归分析来预测区域和全球估算中的缺失值。这些计量经济学方法还用于将支出与健康状况指标相关联。1990年，全世界估计在卫生方面支出了1.7万亿美元（1.7×10¹²），或者按照贫困国家较高购买力调整后为1.9万亿美元（1.9×10¹²）。这笔支出约60%源于公共资金，40%源于私人资金。然而，随着收入增加，公共卫生支出往往会取代私人支出，并在用于健康的收入中所占份额不断增加。
