Incentive Matter
Incentives matter. This is the fundamental concept of economics. People respond to incentives. So, in order for us to predict people’s behavior, we need to think about how the incentives have changed.
For example, when gas prices rise, people buy less gasoline. They, probably, don’t stop buying gasoline. But, they find ways to use less. Maybe they combine their errands and they can take fewer trips.
Prices are powerful incentives. Government policy frequently relies on people’s response to incentives, but often fails to consider all the different ways it effects people’s incentives. For example, there is a strong desire in many corners for people to use less gasoline. One way of the government policy does this is by cafĂ© standards. These are Government mandates for car manufacturers to sell a fleet of vehicles that have an average fuel efficiency at, or above the standard, for example, 25miles per a gallon. The idea is that if car manufacturers produce more fuel efficient cars, consumers will buy more fuel efficient cars and use less gasoline. Sounds great. This is where economics comes in. As a consumer, what happens to my incentive. I buy a more fuel efficient car. Well, now, before it took me 20 gallons gasoline to drive to visit my parents’. Now, maybe it takes me 18. It lowers the cost of me driving to visit my parents. So, I am going to drive to visit my parents more often. The changing mandate reduces the cost of driving and inducing consumers to drive more miles.
A good economist doesn’t just consider the obvious effect of the policy, the changing mandate leads more fuel efficient cars. A good economist also considers the less obvious effects. The changing mandate lowers the cost of driving inducing consumers to drive more miles with the unintended effects on pollution, and car emissions.
Setting right incentive and avoiding unintended consequences is difficult. Incentives matter, is relatively straight forward concept. What's difficult is to think about all the different ways that policy makers might affect people’s incentives and how that would change people’s behavior.
