New Jersey Assembly Speaker Sheila Oliver says studies show right-to-work laws don’t spur job growth

A pair of Republicans in the state Assembly recently introduced a bill that would make New Jersey the 23rd state where workers can opt against joining a union, setting off a debate over the economic impact of so-called "right-to-work" laws.

Assemblywoman Amy Handlin (R-Monmouth/Middlesex), one of the bill’s sponsors, had claimed the move "would quicken New Jersey’s economic revival." But Assembly Speaker Sheila Oliver (D-Essex/Passaic) said the legislation was "dead on arrival."

In a July 8 press release, Oliver explained how right-to-work laws represent bad economic policy.

"Numerous studies have shown that these so-called right-to-work laws do not generate jobs and economic growth," Oliver said in the press release. "In fact, these laws have been found to suppress wages and have had no impact on employment and business growth."

After looking at the research and talking to economic experts, PolitiFact New Jersey ended up with a mixed picture of the impact of right-to-work laws. Some experts argue that the influence of that single policy is difficult to pin down, but others said there is a connection between job creation and right-to-work laws.

First, let’s talk about job growth in those right-to-work states.

Patrick Semmens, a spokesman for the National Institute for Labor Relations Research, pointed out that right-to-work states are producing jobs at a faster rate than other states. A recent ruling from PolitiFact Georgia confirmed that trend.

Handlin argued that higher personal income and lower unemployment rates are examples of right-to-work leading to job growth. Semmens and Handlin both referred to the research done by Ohio University economics professor Richard Vedder.

Vedder told us right-to-work laws were associated with job creation. Even accounting for other factors, right-to-work laws produce positive economic outcomes, he wrote in an email.

Yet some right-to-work states have no state income tax, which could make the relationship between right-to-work laws and income growth seem like a "mirage," Vedder wrote.

Vedder acknowledged how job growth is greater in right-to-work states, but added "that showing a statistical relationship does not necessarily imply causation."

So, are right-to-work laws the reason for the job growth in those states?

Oliver’s spokesman, Tom Hester Jr., sent us an April study from the Washington, DC-based Economic Policy Institute, a liberal think tank, that supports the assemblywoman’s argument. That study claims that since both sets of states "can foster booming job markets, then something in these states’ economies, demographics, or policies other than RTW must be driving their growth."

Roland Zullo, a research scientist in labor and economic studies at the University of Michigan, said there’s no convincing research proving a link between right-to-work laws and job growth or decline. Other factors, such as tax packages, could explain what’s driving companies to right-to-work states, Zullo said.

Another recent study by two economics professors reached a mixed conclusion on the subject. In terms of manufacturing employment, a right-to-work law had no significant impact in Oklahoma, but another right-to-work law increased the number of jobs in Idaho, according to an email from those professors, Serkan Ozbeklik and Ozkan Eren.

Right-to-work laws likely create jobs, but part of the job growth is probably the result of other business-friendly policies in right-to-work states, according to Ozbeklik and Eren.

W. Robert Reed, an economics professor in New Zealand, who had researched right-to-work laws while working in Oklahoma, wrote in a series of emails that right-to-work laws create jobs and increase wages. Right-to-work limits the ability of unions to negotiate benefits to the point of discouraging companies from hiring new employees, Reed wrote.

But Reed noted, as Vedder did earlier, that "correlation does not prove causation."

"Did wages grow faster in RTW states because of RTW legislation? Or because of other factors? That's virtually impossible to determine," Reed wrote. "So many other factors could also have been responsible for job and wage growth in those states."

It’s worth noting that the research is also divided on whether right-to-work laws reduce workers’ wages, as Oliver suggested.

Two studies from the Economic Policy Institute suggest workers in right-to-work states earn less than their counterparts in other states. Ozbeklik and Eren found that right-to-work led to reduced non-union wages in the private sector in Oklahoma.

But Reed argued in a 2003 study that average wages are higher in right-to-work states, when factoring in state economic conditions at the time the right-to-work laws were adopted.

Let’s review:

Oliver claimed that studies show "right-to-work laws do not generate jobs and economic growth." According to different studies and economic experts, the evidence is mixed that right-to-work laws spur job growth.

Right-to-work states have seen greater job increases, but one economist pointed out that such a dynamic doesn’t prove right-to-work laws were the cause. Another professor who believes job growth results from right-to-work laws acknowledged that many other factors also could be responsible.

We rate Oliver’s statement Half True.
