10
Demand Function Q MC = M(HS, DC, ES, PF) l Health status l Demographic characteristics l Economic standing l Physician factors
11
Effect of Insurance on Demand
12
Physician Induced Demand l Physician as agent l Demand creation
13
Demand Inducement
14
Measuring Demand l Price elasticity of demand l Income elasticity of demand l The Rand health insurance experiment
15
Select Studies on Elasticity of Demand
16
RAND Experiment – 1971-82 l Randomly assigned 2,000 non-elderly families to insurance plans differing in 2 characteristics: –Coinsurance rate (0 – 95%) –Deductible (5, 10, or 15% of annual income) –Annual spending cap of $1,000 l Examined 2 important measures: –Health spending –Health outcomes
17
RAND Experiment Spending l Research question: How did assignment to groups affect spending? l Compare the 0% coinsurance group with the 25% group –0% group spent an average of $1,019 –25% group spent $826 (19% less) l Economic lesson: increase the price and reduce the amount consumed
18
RAND Experiment Health Outcomes l Study question: How did assignment to groups affect outcomes? l Health status assessment prior to the study – allows “before and after” l For average person – no substantial health benefits from free care l Exception: chronically-ill poor (6% of the study population)
19
RAND Experiment Conclusions l Instead of free for all care –Targeted benefits for chronic conditions l Better access to primary care –Exempt low-income from cost sharing l Study changed policy debate –Cost sharing limits demand without substantially harming health
20
Summary and Conclusions l Demand for medical care seems to be relatively insensitive to price changes l Individual income elasticities are relatively low indicating that medical care may be a necessity l Aggregate income elasticities are higher indicating that medical care may be a luxury
