The Heritage Foundation has conducted two separate studies that both reach the same conclusion: Federal employees are paid substantially more than comparably skilled private sector workers. Defenders of the federal pay system, including the U.S. Office of Personnel Management (OPM), have mischaracterized The Heritage Foundation’s analyses by suggesting they ignore skill differences between the public and private sectors, resulting in an “apples to oranges” comparison. On the contrary, Heritage has carefully accounted for skill differences, always comparing apples to apples.
While federal employees do earn more partially because they are more skilled than the average private sector worker, controlling for skills does not eliminate the federal pay premium. Depending on the methodology employed, the average federal employee receives as much as 22 percent more in wages than an equally skilled private sector worker. Including both wages and benefits, overpaying federal workers costs taxpayers approximately $40–50 billion per year.
The Heritage Studies
Heritage analyst James Sherk recently published a detailed comparison of federal and private pay in a report from The Heritage Foundation’s Center for Data Analysis. Separately, Heritage analyst Jason Richwine worked with Andrew Biggs of the American Enterprise Institute on a similar study, the results of which were published in The Wall Street Journal. The studies employ different datasets and methodologies, but they draw similar conclusions: Federal workers are overpaid in both wages and benefits at substantial cost to taxpayers.
Federal Pay Debate
Defenders of the federal pay system have responded by arguing that these studies ignore differences in skills and occupations. OPM Director John Berry summarized this view in a recent statement:
The Cato Institute and USA Today stories quoting Cato staff (and similar statements from the Heritage Foundation) look only at gross averages, including retail and restaurant service workers and other entry-level positions that reduce private sector average pay in comparison to the Federal average, which does not include many of these categories in its workforce. The Federal workforce today is highly specialized.
This critique mischaracterizes The Heritage Foundation’s research on federal pay, which expressly controlled for education, experience, and other observable characteristics to make an apples-to-apples comparison between federal employees and private sector workers.
Controlling for Skills and Occupation
Regression analysis allows researchers to break pay differences between groups down into two portions. One is explained by differences in observed characteristics (such as education and experience), while the other contains differences these characteristics do not explain. The unexplained difference in pay estimates how much private sector workers would earn with their measured skills if they worked for the federal government.
Both the Sherk study and the Richwine–Biggs study used regression techniques to compare the wages of federal employees and private sector workers, controlling for variables such as age, education, marital status, race, gender, size of the metropolitan area, and several others.
Federal Employees Earn More Than Comparable Private Workers
Table 1 below shows the results from the Sherk study. A portion of federal workers’ higher cash pay comes from their higher skills, but the government pays the average federal employee 22 percent more per hour than accounted for by observable skills. Restricting the analysis to workers in identical occupations in both sectors still shows a federal hourly wage premium of 19 percent in the Sherk study. In their own analysis, Richwine and Biggs found a premium of 12 percent.
Including the value of non-cash benefits such as health care and pension benefits adds to the federal advantage in total compensation. An apples-to-apples comparison shows that the federal pay system gives many federal workers significantly more compensation than they would get in the private sector. The total premium costs taxpayers $40 billion (according to Richwine and Biggs) or $47 billion (Sherk) per year above market rates.
Not an Isolated Finding
This is not an isolated finding. Academic research consistently shows that the federal government pays more than the private sector. Liberal and conservative economists alike find the same thing. Alan Krueger, the current Assistant Secretary of the Treasury for Economic Policy in the Obama Administration, wrote one of the seminal research papers on federal pay. He compared wages of similar private sector and federal workers and also examined how the wages of workers who joined the federal government changed. In both cases, federal employees earned higher pay.
Not All Federal Workers Are Overpaid
Not all federal employees are overpaid, of course. The government’s seniority-based pay scale divorces compensation from individual performance. Many highly skilled federal workers earn no more (and perhaps even less) than they would in the private sector. Consequently, Congress should not uniformly reduce the pay of all federal employees. Instead, Congress should expand outsourcing to the private sector and replace the General Schedule with a performance-based pay system tied to market compensation. Congress should also bring federal benefits in line with market standards.
Reform the Federal Pay System
Defenders of the federal pay system, including the OPM, argue that federal employees earn higher wages because they perform more skilled work. This is only partially correct. Skill differences explain only a portion of the federal government’s disparate level of pay. After controlling for skills and occupation, the federal government still pays its employees substantially more than they would earn in the private sector. According to two separate Heritage studies, the current federal pay system:
- Pays hourly wages as much as 22 percent above that of comparably skilled private workers; and
- Will overcharge taxpayers approximately $40–50 billion in 2011 when both wages and benefits are considered.
Clearly, reform is needed.
Overtaxing All to Benefit a Few
Congress should not overtax all Americans to overpay workers in the federal civil service. Congress should bring equity to federal pay by replacing the General Schedule with performance-based pay, requiring federal agencies to compete with the private sector, and bringing benefits to market levels.
