Heritage’s Flawed Immigration Analysis

In the Washington Post today, Jim DeMint and Robert Rector of the Heritage Foundation invoke the free‐​market pantheon in arguing their anti‐​immigration stance: “The economist Milton Friedman warned that the United States cannot have open borders and an extensive welfare state.”

They’re halfway right about that. What Friedman actually said was that immigration is “a good thing for the United States…so long as it’s illegal.” He meant that open immigration is highly beneficial to the economy, provided those productive but inexpensive laborers do not have access to welfare. Friedman later wrote that, “There is no doubt that free and open immigration is the right policy in a libertarian state.” Friedman’s problem was with the welfare state, not immigration. His remarks are fundamentally at odds with the position Heritage is trying to argue. 

It’s not the first time that I’ve questioned the free‐​market credentials of my friends at Heritage lately, and that’s making me sad.

On Monday, Heritage released a new study entitled “The Fiscal Cost of unlawful Immigrants and Amnesty to the U.S. Taxpayer” by Robert Rector and Jason Richwine, PhD. I criticized an earlier version of this report in 2007, arguing that their methodology was so flawed that one cannot take their report’s conclusions seriously. Unfortunately, their updated version differs little from their earlier one.

I’m joined in this view by a host of prominent free‐​marketeers. Jim Pethokoukis at AEI, Doug Holtz‐​Eakin at American Action Forum, Tim Kane at the Hudson Institute, and others have all denounced the fundamentals of the Heritage report.

The new Heritage report is still depressingly static, leading to a massive underestimation of the economic benefits of immigration and diminishing estimated tax revenue. It explicitly refuses to consider the GDP growth and economic productivity gains from immigration reform—factors that increase native‐​born American incomes. An overlooked flaw is that the study doesn’t even score the specific immigration reform proposal in the Senate. Its flawed methodology and lack of relevancy to the current immigration reform proposal relegate this study to irrelevancy. 

Even worse, the Heritage study recommends a “solution” to the fiscal problems it supposedly finds. It suggests:

Because the majority of unlawful immigrants come to the U.S. for jobs, serious enforcement of the ban on hiring unlawful labor would substantially reduce the employment of unlawful aliens and encourage many to leave the U.S. Reducing the number of unlawful immigrants in the nation and limiting the future flow of unlawful immigrants would also reduce future costs to the taxpayer.

Professor Raul Hinojosa‐​Ojeda of UCLA wrote a paper for Cato last year where he employed a dynamic model called the GMig2 to study comprehensive immigration reform’s impact on the U.S. economy. He found that immigration reform would increase U.S. GDP by $1.5 trillion in the ten years after enactment.

Professor Hinojosa‐​Ojeda then ran a simulation examining the economic impact of the policy favored by Heritage: the removal or exit of all unauthorized immigrants. The economic result would be a $2.6 trillion decrease in estimated GDP growth over the next decade. That confirms the common‐​sense observation that removing workers, consumers, investors, and entrepreneurs from America’s economy will make us poorer. 

Would decreasing economic growth by $2.6 trillion over the next ten years have a negative impact on the fiscal condition of the U.S.? You betcha. 

Do the authors consider the fiscal impact of their preferred immigration policy? Nope.

For those of us who “grew up” on the fine policy analysis long produced by Heritage, the immigration report is a supreme disappointment. No one has done more than Heritage to promote the importance of dynamic scoring, which is critical to understanding the true effects of government activity on the marketplace. For that organization to have seemingly abandoned its core principles for this important debate is a stinging blow to those of us who crave an honest, data‐​driven debate on the fiscal merits of policy.
