Private Equity and Entrepreneurs: Allies in Productivity (Opinion) Private-equity firms are in the spotlight thanks to Mitt Romney. But they don't deserve the blame they get for destroying jobs any more than young breakouts like Google, says Scott Shane.

Private Equity and Entrepreneurs: Allies in ProductivityMitt Romney's presidential campaign has brought private equity into the spotlight. Critics of the industry charge that it is bad for the economy. Private-equity firms, they say, simply buy companies, fire workers, chop the business into pieces, sell the viable parts and throw the remainder on the bankruptcy heap.

But careful analysis shows that private equity is just another form of entrepreneurship, with the firms profiting from finding opportunities to restructure businesses and generate value.

Few dispute that private-equity firms make money for their investors. One study of private- equity earnings by Bob Harris, a professor at the Darden School of Business at the University of Virginia, and colleagues shows that private-equity funds had returns 20 percent greater than investments in the S&P 500.

More controversial is how private-equity firms generate such high returns. The primary knock on these firms is that they make money by shedding workers. But who ever said we should judge business owners' performance by how many people are employed? Owners are supposed to maximize profits, which are revenues minus costs. And employees are a cost. Sometimes the best way to boost profits is to cut labor costs.

Think about what it would mean if we judged business owners' performance by employment levels. We'd have to conclude that Wal-Mart is much better run than Google. While both companies are worth roughly $200 billion, Google employs 32,000 people to Wal-Mart's 2.1 million.

We should also conclude that superstar entrepreneur Mark Zuckerberg is messing up big time at Facebook. The company is expected to be worth $100 billion when it goes public as expected later this year, roughly the same market capitalization as McDonald's. But Facebook employs 3,200 people to McDonald's 400,000.

Businesses make money when they are more productive than their competitors, and private equity firms tend to boost productivity. A study by Steven Davis of the Booth School of Business at the University of Chicago and colleagues found that productivity at companies taken over by private-equity firms was two percentage points higher than that at a control group of companies over the first two years after an acquisition.

The productivity gains generated by private-equity firms aren't limited to the companies they acquire. Rather, the presence of private-equity firms may help keep other business owners efficient. A study by Shai Bernstein of Harvard Business School and colleagues found that having more private-equity firms in an industry led the rest of the industry to run more efficiently.

Private-equity firms improve productivity, in part, by replacing workers. In an analysis of 3,200 companies between 1980 and 2005, Steve Davis of Chicago's Booth School and colleagues found that both job creation and job destruction are 13 percent higher at companies acquired by private-equity firms than at other businesses. Private-equity firms try to reallocate talent to more productive purposes. If they can't move existing employees to new jobs, they lay them off and hire new workers.

In the end, private-equity firms don't significantly reduce employment. Davis's study shows that all of the firing and hiring results in a net employment decline that is only one percentage point greater at companies acquired by private-equity firms than at other businesses.

When Larry Page and Sergey Brin caused workers to lose their jobs by increasing efficiency with an online search engine called Google, people said they were visionaries. But when Mitt Romney and his gang at Bain Capital caused workers to lose their jobs by increasing efficiency, people said they were vultures.
