In this age of Big Data, empirical economists have increased opportunities to test new ideas for cost-effectively bringing about behavioral change. One recent study set in India provided financial incentives to people at risk of becoming a diabetic to walk more steps each day. Since the study was careful to use a randomization approach to determine who was offered the walking incentive, the existence of a control group means that the researchers can test the hypothesis that well designed financial incentives are a cost-effective way to spur behavioral change among those with a key chronic condition.
How Can the Government Incentivize Behavioral Change?
Arnold Schwarzenegger recently said; “If you stop movement, then this is the first step to death,” he said. “If you rest, you rust,”
This famous Republican is using his social media platform to nudge his fans. Unfortunately, I doubt that this is sufficient to change behavior and encourage greater personal responsibility in building up one’s health. Basic economic logic predicts that the incentives of both “carrots and sticks” are needed. A carrot would be to offer financial payments for those who engage in healthy habits that can be objectively measured such as walking steps being measured by Cell Phone GPS systems. This intervention could eventually pay for itself by lowering future Medicare and Medicaid expenditures.
As the United States now spends roughly 17 percent of GNP on health care, it is important to consider alternative “rules of the game” regarding insurance pricing. If insurers could charge different prices for annual health premiums based on personal attributes such as one’s blood sugar level and one’s weight, then this would introduce a strong financial incentive for people to invest more in being healthy. Our current system’s rules preclude this. Both the rates of chronic disease and their private and social costs are rising. Facing this reality, what steps are the American people willing to introduce to bend this curve?
