A working paper from the Federal Reserve Bank of Boston is challenging the conventional wisdom that tariffs inevitably drag on efficiency and reignite inflation. The research, released Wednesday, found that productivity growth accelerated in the industries most heavily affected by tariffs — and that those gains largely offset the higher costs those firms faced.
“Industries in which tariffs induced higher costs in 2025 also experienced greater labor productivity growth, which helped them mitigate those higher costs,” the researchers wrote.
The findings land amid a broader reassessment of President Trump’s tariff policies, which many economists predicted would produce a sustained burst of inflation. Instead, the Boston Fed’s analysis suggests the inflationary impact was far smaller than feared, even under assumptions most favorable to the doomsayers.
Productivity gains across the board
The study examined 63 industries and found that productivity increased in 37 of them. Across the economy, the researchers calculate that productivity growth reduced production costs by 1.3 percent and subtracted 0.9 percentage point from core personal consumption expenditure (PCE) inflation.
The tariffs themselves raised domestic production costs by an estimated 1.1 percent, according to the paper. When accounting for tariffs on both directly imported goods and domestically produced goods, the researchers estimate that tariffs added 1.4 percentage points to core PCE inflation. Productivity gains erased 0.9 point of that, leaving a net contribution of just 0.5 point.
“Productivity gains thus strongly offset the increase in consumer prices induced by tariffs,” the researchers concluded.
That net effect is modest compared with other forces. Core PCE inflation ran around 3 percent in 2025. The Boston Fed estimates that nominal wage growth contributed 1.9 percentage points — nearly four times the net contribution of tariffs after productivity is taken into account. Even under the paper’s assumption of full pass-through of costs to consumers, tariffs cannot plausibly account for most of the inflation that persisted last year, the authors argue.
A cautious interpretation
The paper stops short of claiming that tariffs directly caused the productivity gains. But it points to several plausible mechanisms. Faced with competitive pressure to keep prices low, firms had a choice between accepting lower profit margins or finding ways to become more efficient. Some invested in new equipment or reorganized production processes. Others reduced labor inputs while maintaining output. The paper also notes that less productive firms may have exited the market, shifting production toward more efficient competitors.
Yet the modeling leans on a strong assumption: that firms pass through higher production costs to customers. Critics might note that in practice, companies often absorb cost increases by trimming margins to protect market share. A firm facing higher costs for components or finished goods may simply accept a tighter profit margin rather than risk losing customers. Even so, the Boston Fed’s results suggest that tariffs had a much smaller inflationary effect than often assumed — even with full pass-through built into the model.
Historical echoes and open questions
The Boston Fed’s findings align with earlier work from the San Francisco Fed, which examined 150 years of tariff policy and found that tariff increases historically lowered inflation while raising unemployment. That paper’s authors proposed that tariffs often act like negative demand shocks, as uncertainty and falling asset prices dampen spending and investment. The Boston Fed’s research adds another possible channel: firms respond by cutting unit costs — which, if sustained, would also reduce the need for labor.
The new paper does not resolve whether the productivity gains are permanent or merely a one-time adjustment to a new tariff regime. Nor does it settle the broader debate over the optimal level of trade barriers. But it does undercut the narrative that tariffs inevitably make the economy less efficient or that they represent a major driver of inflation.
For policymakers at the Federal Reserve, the findings offer a measure of reassurance that the inflation impulse from tariffs may be more limited than originally feared. But with core inflation still running above the central bank’s 2 percent target, the paper suggests that wage dynamics — not tariff policy — are the more important variable to watch.
