What Is the Natural Unemployment Rate?
Let me explain the natural unemployment rate directly: it's the minimum level of unemployment that comes from real or voluntary economic forces in the labor market. You see, this rate accounts for workers who are transitioning between jobs, those displaced by technology, or individuals who simply lack the skills needed for available positions. It's not about economic slumps; it's the baseline unemployment that exists even when the economy is humming along.
In my view, natural unemployment is a normal part of how labor markets function—people are always moving in and out of jobs. Remember, if unemployment is caused by cycles, institutions, or policies, it's not natural. And because of this, you'll never see 100% full employment in any economy; that's just not realistic.
Understanding Natural Unemployment
To understand natural unemployment, consider that 'full employment' is often thrown around as a goal, but it's misleading. There are always people entering the workforce, like new graduates, or those being pushed out by tech advancements. This creates a constant flow in the labor market, which is what natural unemployment captures.
Now, if a recession hits hard, it can push this rate up through something called hysteresis—workers lose skills or businesses shut down permanently. Key thinkers like Milton Friedman, Edmund Phelps, and Friedrich Hayek shaped this idea, especially through the non-accelerating inflation rate of unemployment, or NAIRU. Natural unemployment includes both voluntary choices and involuntary shifts, and it sticks around even after economic recoveries.
Causes of Natural Unemployment
Let's get into the causes. Economists once thought all unemployment stemmed from low demand, fixable with stimulus. But history shows that even in strong economies, workers naturally flow between jobs. Full employment means everyone who wants a job has one, but zero unemployment is impossible—it would require a rigid labor market where no one quits or seeks better opportunities.
In the general equilibrium model, natural unemployment is the gap at perfect labor market balance: workers wanting jobs at current wages versus those able and willing to take them. Factors like minimum wages or strong unions can raise this rate over time. For instance, as of January 1, 2025, 21 states increased their minimum wages, which could influence this dynamic in those areas.

Effects of Inflation on Unemployment
Turning to inflation, John Maynard Keynes suggested in his 1936 book that unemployment and inflation are directly linked—the Phillips curve formalized this, showing they move oppositely. So, full employment might require some inflation, and low inflation could mean higher unemployment.
But the 1970s stagflation—high unemployment and inflation together—busted that idea. It showed no simple correlation between economic strength and inflation levels.
Frequently Asked Questions
You might wonder about natural versus cyclical unemployment: cyclical is the gap between natural and current rates during economic swings. The natural rate matters because it's the lowest sustainable level without sparking inflation. In a recovering economy, it can rise as workers feel confident to switch jobs.
The Bottom Line
To wrap this up, the natural unemployment rate is that baseline from voluntary and structural forces—job flows, tech changes, skill gaps. Full employment is a myth because of it, and only cyclical, institutional, or policy unemployment falls outside this category. Keep this in mind when analyzing labor markets.
