Examples of Using the R-I-A-O Model
To analyze a change in a rule or institution, economists use the following model:
Rules – Incentives – Actions – Outcomes
The rules or institutions in society create incentives for people - they change the costs and/or benefits of doing something (given that people act purposefully). These individual actions then will create noticeable outcomes in society.
Example One: Increasing the minimum wage (a rule regarding the contract that employers and employees make with each other).
Intended Outcome: Higher pay for low skilled workers.
Rule or Institution Change |
Incentives (cost or benefit change) |
Actions |
Intended Outcome |
An increase in the Minimum Wage. |
This rule change increases the benefit to low skilled workers of working (i.e., higher pay). |
Therefore, more low skilled workers continue working at the jobs they have or try to find jobs. |
Those that are employed in low skilled jobs have higher monetary pay. |
Unintended Outcomes: Higher Unemployment, Fewer Non-monetary benefits, more technology to replace workers, and the list goes on and on.
Rule or Institution Change |
Incentives (cost or benefit change) |
Actions |
Unintended Outcome |
An increase in the Minimum Wage |
This rule change increases the cost of hiring people for employers. |
Therefore, employers will hire fewer people. |
An increase in unemployment. |
Rule or Institution Change |
Incentives (cost or benefit change) |
Actions |
Unintended Outcome |
An increase in the Minimum Wage |
This rule change increases the cost of hiring people for employers. |
Therefore, employers will cut costs in other ways other than monetary wages. |
A decrease in employer offered benefits. |
Rule or Institution Change |
Incentives (cost or benefit change) |
Actions |
Unintended Outcome |
An increase in the Minimum Wage |
This rule change increases the cost of hiring people for employers. |
Therefore, employers will use cheaper ways of producing goods and services – including replacing workers with technology. |
An increase in unemployment. |
Example Two: Drug laws (a rule that makes buying and selling certain drugs illegal – with penalties of jail time and/or monetary fines).
Intended Outcomes: Less drug use, therefore less crime and better health within society.
Rule or Institution Change |
Incentives (cost or benefit change) |
Actions |
Intended Outcome |
Outlawing trade in certain drugs. |
This rule change increases the cost (potential) of buying and/or selling certain drugs. |
People buy and/or sell fewer illegal drugs. |
Less drug use, better health, etc. |
Unintended Outcomes: Higher violent crime rates, more overdosing of illegal drugs, and the list goes on and on.
Rule or Institution Change |
Incentives (cost or benefit change) |
Actions |
Unintended Outcome |
Outlawing trade in certain drugs. |
This rule change increases the cost of reporting a “bad deal” when buying and/or selling drugs (which still takes place even with the law in place). |
People who buy and/or sell illegal drugs take contract enforcement into their own hands by harming those who have engaged in a “bad deal” with them. |
An increase in violent crime. |
