New Jersey is one of 13 states that will raise their minimum wage Wednesday, according to the National Employment Law Project, a nonprofit that advocates for raising the wage.
Three states - Connecticut, New York, and Rhode Island - passed laws last year to raise their wages, while the other states are adjusting wages through annual automatic increases, according to the group.
In Pennsylvania, where the minimum wage matches the federal minimum of $7.25 an hour, Democrats have proposed raising it. A proposal in Congress would raise the federal minimum wage to $10.10 an hour.
Sixty-one percent of New Jersey voters said yes last fall to amending the state constitution to raise the wage to $8.25 an hour and include annual increases tied to the Consumer Price Index.
The measure went on the ballot after Gov. Christie vetoed a bill that would have increased the minimum wage to $8.50 an hour and provided annual cost-of-living increases.
The Republican governor said he would agree to a $1 increase phased in over three years, but Democrats in the Legislature rejected his proposal and put the question to voters.
Business groups, including the chamber, argued against the annual CPI increases now cemented in the constitution.
They also have warned of adverse - if not imminent - economic effects, saying businesses will be dissuaded from hiring and will be forced to cut employees or hours or increase prices to cover the added labor costs.
The increase "is something that over a few years is going to have a much more significant impact," Bracken said. The chamber did not oppose Christie's proposal, he said.
In an appearance Tuesday on Philadelphia talk radio's Dom Giordano Program, New Jersey Senate President Stephen Sweeney (D., Gloucester), a proponent of the ballot measure, said the arguments against raising the wage "don't ring true."
"If you need an employee, you're going to hire an employee," Sweeney said. The increase "is not going to ruin the economy. If anything, it's going to help the economy."
Steven Pressman, an economist at Monmouth University, said the higher wage would lessen the incentive for companies to hire new employees.
On the other side, Pressman said, low-wage workers who get a raise will spend it - as will employees who make more than minimum wage but who are bumped up as the pay scale shifts.
"Lots of people are going to have slightly higher incomes," Pressman said. The increased consumer spending would offset incentives not to hire, he said, citing a study done after New Jersey raised the minimum wage in 1992 from $4.25 an hour to $5.05.
The study, which examined fast-food restaurants in two counties in New Jersey and Pennsylvania, found "pretty darn close to zero impact on employment," Pressman said. "What that says to me is the two forces are pretty equal."
While he predicted little impact on New Jersey's economy, Pressman said prices may increase slightly - "five, 10, 15 cents on a McDonald's hamburger."
The bigger issue facing the state's economy will be the loss of federal emergency unemployment benefits, affecting 90,000 New Jerseyans, Pressman said.
Other studies on the effects of wage increases - some backed by business groups - have reached different conclusions.
In June, the National Federation of Independent Businesses released a study that said a wage increase in New Jersey could lead to a loss of 31,000 jobs over 10 years.
Such studies involve "a range that is so statistically small," said Gordon MacInnes, president of New Jersey Policy Perspective, a left-leaning think tank. "You can't make a projection like that . . . in an economy with 4.1 million jobs."
In addition to the 254,000 workers in New Jersey who will get an immediate raise, 189,000 employees in the state make between $8.25 and $9.25 an hour and will receive future increases, according to a report by Policy Perspective.
Of those 443,000 New Jerseyans, 84 percent are at least 20 years old, and most - 362,000 - work 20 hours or more a week, according to the report. One out of four of those workers - and one out of the five getting the raise Wednesday - is a parent.
"This is helping desperate families, who will spend the increased wages immediately and locally," MacInnes said.
About 57 percent of New Jersey minimum-wage earners work for companies with at least 100 employees, MacInnes said.
The industries in New Jersey with the most minimum-wage workers are retail, leisure and hospitality, and education and health care, according to the Policy Perspective report.
John Holub, president of the New Jersey Retail Merchants Association, said retailers "remain quite concerned with the impact" of the wage increase. He dismissed the argument that businesses would benefit from increased consumer spending. "Where does the money come from?" Holub said. "The only guarantee for businesses is increased labor costs. Something's got to give."
Dolores Riley, who owns Gramma's Schoolhouse, a day-care center in Cinnaminson, feels her options are limited.
As a day-care operator, she said, she can't cut staff: The state requires a certain number of employees for the children in the building.
Of her 16 employees, about half make $8 an hour and will get a 25-cent raise. Riley said it was only fair that her other employees, who have worked for her longer, get a raise as well.
"That amounts to quite a bit of money. And day cares are not a rich business - never will be," she said.
Riley said she does not know how she'll manage the increase. "I just know that I'm worried," she said.
