Is Private Equity's Slash-and-Burn Reputation Overblown?

Buyouts don't follow a singular path of layoffs and closures to bolster profits for partners, says research by Josh Lerner. Instead, workforce changes can stimulate productivity after deals.

Everyone knows the stereotype of a private-equity buyout. First come big layoffs, then streamlining to boost profits, and finally a sale that enriches the firm’s partners.

The reality is far more nuanced, finds a first-of-its kind study mapping the career fates of 2.5 million US workers at 3,600 firms purchased by private-equity (PE) companies over two decades. Researchers tracked workers at companies that were bought out by PE firms for three years, and compared their fates to workers at comparable firms that weren’t bought out.

On the surface, they found that employees working at bought-out companies are more likely to leave their jobs than their non-buyout counterparts, and more likely to become unemployed and suffer wage cuts—earning almost 18% less three years after a deal. However, many employees move on to jobs with similar pay.

Contrary to the slash-and-burn image of PE, buyouts bring both “good and challenging aspects,” says Lerner, the Jacob H. Schiff Professor of Investment Banking at Harvard Business School. The findings offer a fresh way to think about today’s PE industry and its effect on labor markets.

Lerner wrote Private Equity and Workers: Measuring Monopsony, Implicity Contracts, and Efficient Reallocation with Kyle Herkenhoff, a professor at the University of Minnesota; Gordon M. Phillips, a professor at the Tuck School of Business at Dartmouth; Benjamin Sampson, a doctoral student at Stanford University; and Boston University lecturer Francisca Rebelo.

They set out to examine some common stereotypes of an industry that has grown 10-fold since 2008, chiefly that PE investors treat workers in targeted markets unfairly. Instead, they found PE firms stimulate productivity through a series of steps, which may include the movement of personnel and changing incentives.

Tracking reorganized companies

Twenty years of data from the Internal Revenue Service and the US Census Bureau allowed the authors to trace thousands of individuals and facilities—such as factories, warehouses, and other business sites—at acquired firms and compare them to people and like facilities that weren’t part of a leveraged buyout.

Inside the research

The researchers matched workers and facilities from acquired companies with a control group, using government data from 1993-2013. They analyzed:

  • 2.5M
    Workers from acquired companies
  • 3.6k
    Acquired companies
  • 33%
    Share of sample in manufacturing, followed by 14% in wholesale trade

Aligning the data granularly made it easier to compare reorganized firms. When a PE firm acquires a company, the new owners often split it up or create shell companies to transfer debt or assets into new entities.

“Rather than looking at the firm as a whole, because there's so many acquisitions and divestitures, we're really looking at worker-by-worker level, trying to avoid many of those problems,” Lerner says.

Salary cuts, but fairly stable employment

The researchers found that workers lost jobs and wages after buyouts—but not for the reasons they expected, nor to the extent they anticipated.

Employees were only 2% less likely to be employed after three years. While wages shrank by 18% for workers who left the acquired company during that time, employees unable to find new jobs shouldered most of those losses. Among employees who found new jobs within three years, wages shrank only 0.5%.

The authors closely examined “breaches of trust”—the idea that PE firms identify and target workers who have been at a bought-out company for many years or those who earn more than their peers. They looked in particular at the 10% best-paid workers to see if they were more likely to be laid off. They examined managers and scrutinized different subsamples, such as minorities. They found nothing statistically significant, Lerner says.

The criticism that layoffs follow PE takeovers because the investors operate as “monopsonists”—underpaying workers because they dominate a local market—also isn’t supported by the data, says Lerner.

“We're not able to find any real, convincing proof that that's the case,” Lerner says. “And remember, we're talking about millions of observations here. … We're still not able to find anything that has statistical significance.”

Instead, PE firms tend to target staff cuts at less productive plants versus those factories that are more efficient. They also tend to move better-performing employees to more productive plants. The pattern holds true mainly for workers who earn higher wages. These findings suggest that boosting productivity is a top goal for buyout firms when considering how to manage the workforce after the deal, the authors note.

A more nuanced view of PE

The findings may not satisfy anyone’s view of PE firms, Lerner says. Nevertheless, policymakers, investors, and managers should take a step back and allow for a less linear look.

“One just needs to take a much more nuanced view of the PE industry—the industry and its impact, Lerner says. “That’s a tough row to hoe in this day and age where everything seems so polarized.”
