The more common example is an incomplete study. The latest example is research on the impact of immigration on unemployment and wages.
Mixing the Melting Pot: The Impact of Immigration on Labor Markets
We used state-level data from the U.S. Census Bureau for the years 2000, 2005 and 2010 for wages and immigration figures.A period with an oil and housing boom, two recessions, one of which was a financial collapse. All of which were far more important short-term factors for wages and unemployment. the most important factor is capital because wages are a function of labor and capital. The U.S. experienced a credit boom that ended in 2007. Rising credit supported wages, home prices, and demand for labor to build new homes.
But the Overton Window has shifted. Economists are no longer claiming immigration increases wages or reduces unemployment, they're trying to rebut the argument that mass immigration has a negative effect on wages.
Too bad there's already plenty of evidence for rising wages.
Amid Trump's Immigration Crackdown, More Mexicans Get Visas to Work in U.S.
Huh. Aren't we constantly told there aren't enough visas? Yet the number rises 20% after a crackdown on illegal aliens. Farmers and businesses prefer cheap labor, even if it is illegal.
Michigan fruit growers say 'Trump effect' is making their life harder
The demand for migrant workers is driving up wages and encouraging some growers to mechanize.Legal visas are up. The wages of those who go through the legal process are up. The losers are illegal aliens and the businesses who relied on their labor.
More growers also are applying for "H2A" visas to ensure there will be enough workers available for the harvest.
"I haven't heard anybody complaining they cannot find labor, but I have heard complaints that there's not enough labor," said Mark Longstroth, a Michigan State University Extension Service tree fruit expert based in Paw Paw.
Wages for migrant workers are rising in Michigan as growers compete for their services. An estimated 90,000-plus migrant workers arrive in Michigan every year to help with the harvest, which starts with asparagus in the early spring and ends with the apple crop in the fall.
Migrant workers in the Great Lakes region were being paid an average of $12.28 an hour this spring, a 5.5 percent increase over the same time last year, according to U.S. Department of Agriculture statistics.
"Studies" show immigration doesn't impact wages and unemployment. Reality says different.
