Immigration debate crux: jobs impact Experts weigh how illegal workers affect US employment.

It's all about supply and demand.  The more you have of any commodity, including labor, the less you pay for it.  Economists only have trouble understanding this when it applies to the working and middle class employees as this article from 2006 indicates.---rng

I will put this as delicately as I can. The economists for JP Morgan Chase etc. are paid hacks for these companies. Their research is suspect because they are beholden to the bankers who make loans to large construction corporations and agribusinesses. I don't think they are trying hard enough when they say they don't have enough data to make econometric models. But that's just me. ----lee.

     Seal the border. Round up all the illegal immigrants and send them back to their home countries. Start a whole new agency to handle only invited guest workers.

     Would that open up more jobs for American citizens?

     This is one of the key questions being posed as the US considers the economics of illegal immigration - with no easy solutions to the challenges in sight.
     As Congress debates a new immigration bill, some economists believe any restrictions are likely to be disruptive to a variety of industries, from construction to hospitality to agriculture. At the very least, restrictions could add to employers' costs as they scramble to attract new workers with higher wages. But new regulations might also be good for those without much education or marketable skills: Business might be forced to train them. And those in lower wage brackets might see their wages rise as they face less competition for jobs.
     "Do undocumented workers take away jobs from Americans?" asks Anthony Chan, chief economist at JPMorgan Private Client Services in Columbus, Ohio. "My best guess is that they take some jobs away. Some Americans are willing to work at those jobs at low salaries, but not all [Americans are]."
     Analysts are quick to point out that the economics of undocumented immigration are complex. Few models have been crafted that try to look at how the US economy would perform without tapping into inexpensive labor for some jobs.
     "We can't run econometric models. The numbers aren't good enough," says David Wyss, chief economist at Standard & Poor's in New York.
     One challenge in performing any calculations is agreeing on the number of undocumented workers. Only estimates exist, and they range from 9 million to 20 million. The conventional estimate is 11 million. But no one really knows for sure.
     By way of contrast, the Bureau of Labor Statistics calculates how many people out of a workforce of 143 million are unemployed. Last month, 7,193,000, or 4.8 percent, were out pounding the pavement.
The Center for Immigration Studies, which is in favor of some restrictions on immigration, recently issued a report looking at jobs and undocumented workers. One of its conclusions was that between March 2000 and March 2005, only 9 percent of the net increase in jobs for adults went to people born in the US.
     "This is striking because natives accounted for 61 percent of the net increase in the overall size of the 18- to 64-year-old population," writes Steve Camarota, director of research.
     Howard Hayghe, an economist at the Department of Labor, confirms that this number is correct. But he also points out that by 2005, the economy was doing a better job of producing jobs - and the percentage of native-born residents finding jobs rose to 41 percent. In other words, the stronger economy absorbed more workers of all educational levels. "The more office buildings you build, the more people you need to clean them. The more roads you build, the more workers you need," says Mr. Hayghe.
