The news: Corruption and government often go hand in hand. And in the United States, taxpayers are literally paying the price for that relationship — in the sum of tens of billions of dollars.

In a new study from Indiana University and City University of Hong Kong, researchers defined the 10 most corrupt states and the 10 least corrupt states in the U.S. The 10 most corrupt states spent an average of $1,308 extra per capita — 5.2% of the mean per capita expenditure.

There is a strong correlation between elevated state spending and corruption in all but one of the states (South Dakota is the only exception).

"States with higher levels of corruption are likely to favor construction, salaries, borrowing, correction, and police protection at the expense of social sectors such as education, health and hospitals," the report said.

Key findings: The study looked at 25,000 convictions of violating federal anti-corruption laws between 1976 and 2008, and also generated a "corruption index" comparing convictions and the amount of government employees. After looking at the data, the researchers determined the top 10 most corrupt states are:

1. Mississippi

2. Louisiana

3. Tennessee

4. Illinois

5. Pennsylvania

6. Alabama

7. Alaska

8. South Dakota

9. Kentucky

10. Florida

Not only do these states have excessive state spending, but they also spend more in areas of the government that are susceptible to corruption, like construction jobs, governmental employee wages and law enforcement.

Many of the corrupt states exhaust a lot of money on big infrastructure projects for which the money trail is not fully transparent to the public. Extortion, bribes and kickbacks may cause a rise in expenditures. These states also pay police and correction officers higher wages.

And areas which are not so easily corruptible — like public welfare, education and health — see much less state funding.

Based on the same method, the study found the 10 least corrupt states. They are

1. Oregon

2. Washington

3. Minnesota

4. Nebraska

5. Iowa

6. Vermont

7. Utah

8. New Hampshire

9. Colorado

10. Kansas

Global perspective: In 2013, the United States scored a 73 out of 100 (0 was the worst, 100 was the best) in Transparency International's ranking of the most and least corrupt countries in the world. And out of the 177 countries evaluated, the United States came in 19th place, ordered from least corrupt to most.

Transparency International said, "The world urgently needs a renewed effort to crack down on money laundering, clean up political finance, pursue the return of stolen assets and build more transparent public institutions.”

Those are choice words originally intended for the global ear, but apparently many of the United States should try and heed their advice as well. If they did, they would save American taxpayers billions of dollars.
