Tax Rates Impact Economic Performance, but other Policies also Matter

By Daniel J. Mitchell @ CATO (September 17, 2012)

…even though I’m a big advocate for better tax policy, the lesson from the Economic Freedom of the World Index…is that adopting a flat tax won’t solve a nation’s economic problems if politicians are doing the wrong thing in other areas.

There are five major policy areas, each of which counts for 20 percent of a nation’s grade.

  1. Size of government
  2. Regulation
  3. Monetary Policy
  4. Trade
  5. Rule of Law/Property Rights

Now let’s pick Ukraine as an example. As a proponent of tax reform, I like that lawmakers have implemented a 15 percent flat tax.

But that doesn’t mean Ukraine is a role model. When looking at the mix of all policies, the country gets a very poor score from Economic Freedom of the World Index, ranking 125 out of 141 nations.

Conversely, Denmark has a very bad tax system, but it has very free market policies in other areas, so it ranks 15 out of 141 countries.

In other words, tax policy isn’t some sort of magical elixir. The “size of government” variable accounts for just one-fifth on a country’s grade, and keep in mind that this also includes key sub-variables such as the burden of government spending.

Yes, lower tax rates are better for economic performance, just as wheels matter for a car’s performance. But if a car doesn’t have an engine, transmission, steering wheel, and brakes, it’s not going to matter how nice the wheels are.

Not let’s shift from theory to reality. Here’s the historical data for the United States from Economic Freedom of the World. As you can see, overall economic policy moved in the right direction during the Clinton years and in the wrong direction during the Bush-Obama years.

To be more specific, the bad policy of higher tax rates in the 1990s was more than offset by good reforms such as lower trade barriers, a lower burden of government spending, and less regulation.

Similarly, the good policy of lower tax rates last decade was more than offset by bad developments such as a doubling of the federal budget, imposition of costly regulations, and adoption of two new health entitlements.

This is why I have repeatedly challenged leftists by stating that I would be willing to go back to Bill Clinton’s tax rates if it meant I could also go back to the much lower levels of spending and regulation that existed when he left office.
