Claim analyzed
“Excessive government spending is the primary cause of inflation in Western economies.”
The Conclusion
Executive Summary
The claim is misleading. While government spending contributed to recent inflation in some Western countries, credible Federal Reserve research shows supply chain disruptions, energy shocks, and global factors were primary drivers. The evidence doesn't support spending as the dominant cause across Western economies generally.
Warnings
- The claim cherry-picks evidence from specific pandemic periods while ignoring broader research showing minimal government spending effects on inflation in developed countries
- Key alternative causes like supply chain disruptions, energy shocks, and global factors are omitted despite being identified as primary drivers by Federal Reserve banks
- The claim conflates 'aggregate demand shocks' with 'government spending' when many studies measure broader policy effects including monetary accommodation

The Debate
The for and against arguments
Multiple independent, high-authority analyses identify fiscal expansion—i.e., elevated government spending/deficits—as the dominant demand-side driver of recent Western inflation: the Federal Reserve Bank of New York finds aggregate-demand shocks tied to government expenditures explain roughly two-thirds of model-based inflation (Source 1, Federal Reserve Bank of New York), while MIT Sloan quantifies federal spending as the “overwhelming driver” of the 2022 spike (42% of inflation, two-to-three times larger than any other factor) (Source 7, MIT Sloan). This conclusion is reinforced by evidence that deficit shocks materially raise the price level (about 30% of 2021–22 inflation attributable to 2021 deficits) (Source 10, London School of Economics) and by euro-area results showing fiscal expansions become especially inflationary at high debt levels (Source 6, European Central Bank), together supporting the claim that excessive government spending is the primary cause of inflation in Western economies.
Your reliance on Source 1 (Federal Reserve Bank of New York) fundamentally misrepresents the evidence, as it only examines "aggregate demand shocks" that include government expenditures alongside private consumption and investment—not government spending alone—while you completely ignore Source 11 (Aarhus University) which directly contradicts your claim by finding "prices decline significantly and persistently in response to an increase in government spending." You cherry-picked MIT Sloan's 42% figure while dismissing the authoritative Source 3 (Federal Reserve Bank of St. Louis) finding that "a 10 percent increase in government spending led to an 8 basis point decline in inflation" with effects "not statistically different from zero," demonstrating that your selective use of evidence cannot overcome the preponderance of Federal Reserve research showing minimal to negative effects of government spending on inflation.
Multiple Federal Reserve studies conclusively refute this claim, with Source 3 (Federal Reserve Bank of St. Louis) finding "almost no effect of government spending on inflation" and Source 2 (Federal Reserve Bank of Philadelphia) showing "little evidence of a tie between deficit spending and inflation" in developed countries, while Source 4 (Federal Reserve Bank of Dallas) and Source 5 (Federal Reserve Bank of St. Louis) demonstrate that global supply chain disruptions, energy price shocks from OPEC decisions, and international factors were the primary drivers of recent inflation. The evidence overwhelmingly shows that supply-side disruptions and global commodity price volatility, not government spending, were the dominant causes of Western inflation during the pandemic era.
Your “conclusive refutation” hinges on misapplying broad, often pre-pandemic or cross-country correlations to a specific inflation episode: Source 3 (Federal Reserve Bank of St. Louis, 2016) and Source 2 (Federal Reserve Bank of Philadelphia) don't negate the episode-specific decompositions showing fiscal-driven demand was dominant, like Source 1 (Federal Reserve Bank of New York) finding government-linked aggregate-demand shocks explain roughly two-thirds of model-based inflation and Source 7 (MIT Sloan) attributing 42% of the 2022 spike to federal spending (with Source 10, LSE, adding ~30% of 2021–22 inflation from 2021 deficits). And even if Source 4 (Federal Reserve Bank of Dallas) and Source 5 (Federal Reserve Bank of St. Louis) document major global supply/energy shocks, you commit a false dichotomy by treating their presence as proof spending wasn't primary—those shocks can be important while fiscal expansion still supplies the largest quantified share of inflation in the key Western surge (Sources 1, 7, 10).

The Adjudication
How each panelist evaluated the evidence and arguments
The most reliable sources are the Federal Reserve Banks (Sources 1-5, authority score 0.95), which present conflicting evidence: Source 1 (NY Fed) supports the claim finding government expenditures explain two-thirds of model-based inflation, while Sources 2-3 (Philadelphia and St. Louis Fed) refute it showing "little evidence" and "almost no effect" of government spending on inflation, with Source 5 (St. Louis Fed, 2023) attributing recent inflation primarily to supply chain disruptions and energy shocks. The evidence from these top-tier sources is mixed rather than conclusively supporting the claim that government spending is the "primary" cause, with supply-side factors appearing equally or more significant in recent Western inflation episodes.
The proponent's chain (NY Fed staff model attributing ~2/3 of model-based inflation to aggregate-demand shocks when government expenditures are included [1], MIT Sloan attributing 42% of 2022 inflation to federal spending [7], and LSE estimating ~30% of 2021–22 inflation from 2021 deficits [10], with ECB showing stronger fiscal-inflation effects at high debt [6]) supports that fiscal policy can materially contribute to inflation in particular episodes, but it does not logically establish that “excessive government spending” is the primary cause of inflation across Western economies because several cited estimates are episode- and country-specific, use broader “demand shocks” not uniquely identified as spending, and still leave large residual shares to other drivers. Given the scope mismatch and the presence of credible counterevidence that finds little/near-zero average spending effects in developed-country data [2,3,11] and substantial roles for global supply/energy shocks [4,5], the claim is misleading rather than proven true.
The claim's framing (“primary cause” across “Western economies”) omits that much of the post‑pandemic inflation surge is attributed in major central-bank accounts to global/sectoral supply and energy shocks and common international factors (Source 4, Federal Reserve Bank of Dallas; Source 5, Federal Reserve Bank of St. Louis), and it also glosses over that some cited pro-fiscal work is episode- and model-specific and not cleanly identified as government spending alone (Source 1, Federal Reserve Bank of New York) while broader developed-country evidence finds little systematic deficit–inflation link (Source 2, Federal Reserve Bank of Philadelphia) and some empirical work finds near-zero/negative spending effects (Source 3, Federal Reserve Bank of St. Louis; Source 11, Aarhus University). With full context, it's plausible that fiscal stimulus materially contributed to 2021–22 inflation in some countries/periods (Sources 7, MIT Sloan; 10, LSE; 6, ECB), but the blanket statement that “excessive government spending” is the primary cause of inflation in Western economies is misleading and not generally supported as a dominant explanation across the West.
Adjudication Summary
Source quality was mixed with top Federal Reserve banks providing conflicting evidence - some supporting fiscal contributions while others found "little evidence" of spending effects. Logic analysis revealed the claim overgeneralizes from specific pandemic episodes to all Western economies, with supporting studies often measuring broader "demand shocks" rather than spending alone. Context evaluation showed the claim ignores that major central banks attribute recent inflation primarily to supply disruptions and global factors, not fiscal policy.
