Fed Independence & the Fiscal-Monetary Boundary

4 tier-5 · 0 tier-4

Across these pieces Cochrane treats "Fed independence" not as a slogan but as a contested boundary between central bank and Treasury that only holds if the Fed retains the right to say "no" — above all the right to refuse war-finance debt monetization in the next major crisis. He reads the proposed new Fed-Treasury Accord through the lens of the original 1951 Accord (the Fed reclaiming, not surrendering, its independence), gives a fiscal-theory account of how Korean-War inflation rose and vanished without a Volcker-style recession, steelmans the case that independence should be paired with a narrow accountable mandate, and maps the entire current research frontier on independence, fiscal dominance, and dollar dominance. The cluster matters because it locates the real threat to price stability in the fiscal-monetary boundary rather than in interest-rate tactics.

Trump and monetary policy: Full Oped

TIER 5 Nov 23, 2025

Cochrane's full WSJ op-ed argues Trump's three monetary desires are not crazy: that persistently lower rates may not raise inflation much (citing empirical near-zero responses and the New Keynesian long-run implication that lower rates eventually lower inflation, plus Japan/ZLB evidence); that Fed independence is not an absolute virtue and should be paired with a narrow accountable mandate; and that 'exorbitant privilege' can be a resource-curse when the bounty is consumed not invested. A sharp, original contrarian framing that steelmans positions while rejecting tariffs and capital controls.

1951

TIER 5 Feb 16, 2026

Drawing on Hetzel-Leach's narrative of the 1951 Treasury-Fed Accord, Cochrane gives a fiscal-theory reading of why Korean-War inflation surged (prospective WWIII deficits, price-control and rationing fears) and why it vanished without a Volcker-style rate spike or recession (the war-escalation odds fell, a one-time fiscal shock yielding one-time inflation, echoing 2021-22). He extracts a forward-looking lesson: the real test of Fed independence is whether it will refuse war-finance debt monetization in the next major crisis (Taiwan, war). A landmark historical-analytical piece with lasting reference value.

A new Fed-Treasury Accord?

TIER 5 Feb 17, 2026

Cochrane reframes the proposed new Fed-Treasury Accord (per Warsh's comments) as the opposite of Fed capitulation: invoking the 1951 Accord signals the Fed wants the right to say 'no,' shrink its footprint, and preserve independence. He lays out a concrete three-item agenda: Treasury (not Fed) owns the debt maturity structure with the Fed buying only short-term bonds or lending against collateral; the Fed exits credit allocation like MBS purchases; and both prepare rules for crisis-time debt monetization. A durable policy framework on the fiscal-monetary boundary.

Hoover Monetary Policy Conference 2026 Overview Essay

TIER 5 Jun 2, 2026

A long, co-authored overview essay synthesizing the entire 2026 Hoover Monetary Policy Conference on central-bank independence, fiscal dominance, the dollar's reserve status, mandate/tools, and the AI-boom rate question, with detailed summaries of each presenter (Nelson, Wilcox, Bordo, Eichengreen, Lustig, Krishnamurthy, Redding, Rogoff, Garicano, Duffie, Bowman, Daly, Goolsbee, Waller, Goodspeed). It is a high-density reference capturing the current research frontier on Fed independence, fiscal pressure, dollar dominance, and AI's effect on the natural rate. Durable reference value as a single-document map of the field's leading debates.

Fiscal Theory & the Origins of Inflation

3 tier-5 · 1 tier-4

This is the core of Cochrane's research program: inflation is fundamentally a fiscal phenomenon, and the price level is anchored by the discounted present value of government surpluses rather than by interest-rate rules. Across these pieces he shows that "supply" and "demand" shocks can move inflation while only a fiscal shock permanently shifts the price level, dissects the academic shock-accounting literature that mislabels fiscal effects as innocent supply shocks, walks Brazil's multi-decade inflation history as a sustained FTPL case study where regime credibility (not rate moves) does the work, and traces how a relative price shock becomes general inflation through policy responses that blunt the marginal price signal. The cluster matters because it offers a unified counter-framework to the standard "the Fed controls inflation via rates" story.

Brazilian Inflation and Disinflation

TIER 5 Nov 22, 2025

Cochrane uses a capsule history of Brazil's chronic inflation, failed 1980s stabilizations, the successful 1994 Plano Real, and the post-2000 inflation waves as a sustained fiscal-theory-of-the-price-level case study, arguing the end of serious inflation comes from the combination of monetary, fiscal, and microeconomic reform — and crucially from a credible change of regime, not a sequence of policy actions. The Lula-2002, Rousseff/Temer, and 2016 spending-cap episodes show inflation responding to anticipated fiscal credibility (or its loss) rather than to interest-rate rules, with the policy rate moving roughly one-for-one and the deficit doing the real work. Durable reference value as a multi-decade FTPL teaching example with explicit lessons for a US monetary-fiscal collision.

How to turn a price shock into inflation

TIER 4 Mar 19, 2026

Cochrane uses the EU's energy-subsidy 'toolbox' to argue that a relative price shock (energy dearer than other goods) becomes general inflation chiefly through policy responses: paying consumers' extra costs preserves demand above supply and diverts the rebate into other goods, while price caps recreate 1970s shortages and 'easing the gas-power link' is windfall-profits control by another name. The durable lesson is that prices are a signal wrapped in an incentive, and blunting the marginal signal is how Europe converted the last energy shock into inflation.

Supply Shocks and Nominal Anchors

TIER 5 Jun 11, 2026

Working within an FTPL-augmented New-Keynesian model, Cochrane shows that 'supply' and 'demand' shocks can move inflation even with no change in monetary or fiscal policy, yet only a fiscal shock permanently changes the price level — resolving the puzzle via discount-rate variation in the present value of surpluses. The key original insight: the nominal anchor is the discounted value of surpluses (not surpluses themselves), so real shocks shift the anchor through real-interest-rate changes, which is why fiscal theory feels invisible to practitioners. A substantive model-driven argument with lasting reference value for FTPL and the supply-shock-vs-fiscal debate.

Shock Accounting.

TIER 5 Jun 14, 2026

Cochrane dissects the academic 'shock-accounting' literature (Bernanke-Blanchard, Kaplan-Miyahara, etc.) that attributes 2021-22 inflation to supply/demand shocks rather than fiscal policy, arguing the methods mislabel the 'rule' part of monetary/fiscal policy as innocent and treat literal models as truth. His core point — causation is about counterfactuals along the whole path, the price level's permanent 20% rise can only come from a fiscal/monetary anchor, and 'supply shocks caused inflation' does not say what it sounds like — is a durable framework for reading the entire shock-attribution debate. Includes a worked flexible-price NK example showing how shocks are reverse-engineered as equation residuals.

Economic Methodology & Causal Inference

2 tier-5 · 1 tier-4

These pieces are Cochrane on how to read empirical economics. He develops Tyler Muir's "causation does not imply variation" into a full critique of the causal-identification revolution — identifying that x causes y answers a different question from what causes the variation in y, and the two are constantly conflated. He extends the same methodological skepticism to the markup/markdown literature, defending near-perfect-competition readings against declarations of market "failure" drawn from estimated prices, and reviews an AI refereeing tool in a way that doubles as a candid map of the open questions in his own fiscal-theory work. The cluster matters as a reusable toolkit for spotting when empirical claims overreach their identification.

Causation Does not Imply Variation

TIER 5 Nov 10, 2025

Cochrane develops Tyler Muir's catchphrase into an original methodological essay: identifying a causal effect of x on y (the 'causality revolution' of diff-in-diff, fixed effects, controls, and instruments) answers 'do changes in x cause changes in y' but not 'what are the main causes of variation in y' — and the two are constantly conflated because causal identification works precisely by throwing out most of the variation. He applies this to minimum wages, stock-price pressure/elasticities, and identified monetary-policy shocks (which explain almost none of observed inflation/output), arguing for a complementary big-picture, historical-episode style of inference (Sargent's hyperinflation plot, growth theory, FTPL sorting) that causal techniques cannot replace. A durable, quotable framework for reading empirical economics.

Refine

TIER 4 Feb 24, 2026

Cochrane reviews 'refine,' an AI tool for critiquing academic papers, after feeding it his inflation booklet, and reproduces its comments on operationalizing the fiscal-news narrative, the FTPL-vs-New-Keynesian regime distinction, the rate-hike transmission mechanism, and a sophisticated monetarist (IOR/ample-reserves) objection. He judges the output top-5% referee quality and predicts AI will transform refereeing and paper-writing. Doubles as a candid window into the open questions in his own fiscal-theory-of-the-price-level work.

EFG Review

TIER 5 Mar 2, 2026

A substantive conference review of three NBER EFG papers that turns into an original critique of modern macro's markup/markdown literature. Cochrane defends near-perfect-competition readings of complete dollar-for-dollar cost pass-through ('cheapflation') and of a null minimum-wage 'markdown' result, arguing measured markups and markdowns mostly reflect Hayekian unobserved heterogeneity (fixed-vs-marginal cost and marginal-product mismeasurement), and faults China-shock welfare simulations that ignore the existing safety net. Lasting reference value for its methodological skepticism about declaring market 'failures' from estimated prices.

Asset Pricing & Market Microstructure

1 tier-5 · 1 tier-4

Cochrane the asset-pricing theorist appears here, insisting on equilibrium discipline: any claim that flows mechanically move prices must name the friction and the Modigliani-Miller benchmark it violates, and one must follow the money to its final resting place. He uses the SpaceX IPO and index-fund inelasticity scare to separate the genuine worry about passive investing from the mechanical-inflation myth, and digests NBER asset-pricing papers on short-selling fees, endogenous demand elasticities, and return forecasting — adding his own arbitrage arithmetic showing why large price inefficiencies can coexist with tiny return inefficiencies. The cluster matters as teachable method for reasoning about prices, elasticities, and arbitrage.

NBER Asset Pricing Lessons

TIER 4 Nov 8, 2025

A working review of three NBER Asset Pricing papers: Daniel-Klos-Rottke on the security-lending market, where extreme short-sale fees produce a believable -75%/year alpha that the lending fee exactly offsets (so ownership is break-even while shorting is blocked); Chaudhry-Li on endogenous, size-declining demand elasticities (small flows move price ~2x, larger flows ~1x); and Chen-Hoberg-Zhang's 200-years-of-news nearest-neighbor return forecasting confronting the N»T problem. Cochrane adds his own arbitrage arithmetic (a 1% permanent price error is only ~1.5bp of expected return) explaining why large price inefficiencies coexist with tiny return inefficiencies. Useful conference digest with original interpretive value but conditional on the underlying papers.

Tech Stock Singularity

TIER 5 May 31, 2026

Prompted by the SpaceX IPO and claims that inelastic index-fund demand mechanically inflates new large stocks 'to infinity,' Cochrane walks through the equilibrium logic showing there must be a Modigliani-Miller benchmark with no effect and that any real effect requires a stated friction — follow the money to its final resting place. He then articulates the genuine worry about passive investing (index funds are inelastic; the market needs someone doing research to set a sloping demand curve) while arguing the overall elasticity need not fall. A clear, teachable asset-pricing explainer with lasting methodological value (always state the MM violation).

Energy Shocks, Oil & Stagflation Risk

0 tier-5 · 4 tier-4

Triggered by the Iran/Gulf conflict and the resulting oil-price runup, this cluster restates Cochrane's central applied thesis: energy-price spikes cause recessions only when bad government policy (price controls, windfall taxes, export bans, fiscal handouts, slow Fed reaction) compounds them — the spike itself is a headwind, not a recession. He reads oil spot-and-futures prices to argue traders expect a swift return toward $65, interprets rising long-term rates through TIPS-vs-nominal spreads as higher real rates rather than an inflation or default premium (with a memorable "always read the axes" data-literacy moral), and frames the new Fed chair's dilemma as a possible 1979-style stagflationary shock. The cluster matters as a real-time application of fiscal theory to the energy-and-war news cycle.

War and Oil

TIER 4 Mar 15, 2026

Reading oil spot-and-futures prices during the Iran/Gulf conflict, Cochrane argues the runup is smaller than after Russia's Ukraine invasion and that futures markets expect a swift return toward $65, so doom forecasts are a contrarian bet against traders. He stresses demand substitution and latent supply (marginal wells, fracking, Saudi pipelines, Venezuela) and judges the US fracking-enabled energy position makes this a 'headwind' not a recession, unless a financial shock or ham-handed policy response converts it into inflation.

War and Interest Rates

TIER 4 Mar 30, 2026

Cochrane interprets the sharp rise in long-term rates amid the Iran war via three channels bonds could be signaling — expected inflation, higher future short rates, or loss of faith in government debt — and uses TIPS-vs-nominal Treasury spreads to argue it reflects higher real rates, not an inflation or default premium, and is not forecasting recession. The piece doubles as a fiscal-theory lesson (governments turn an oil shock into inflation by sending people money) and a sharp methodological warning to 'always read the axes' after showing the 'spike' is small in proper perspective. Substantive markets-and-policy analysis with a memorable data-literacy moral.

The Iran War Doesn't Have to Be a Rerun of 'That '70s Show'

TIER 4 May 1, 2026

A full Wall Street Journal op-ed arguing that energy-price spikes cause recessions only when bad government policy (price controls, windfall taxes, export bans, fiscal handouts, slow Fed reaction) compounds them — not the spike itself. Cochrane marshals the structural case that the US is now a net energy exporter with a less oil-intensive economy, and warns the Fed not to 'look through' an oil-shock inflation as it did with Covid. A complete, well-argued policy essay restating his 'don't turn a price shock into inflation' thesis with current application.

Warsh's Challenges: Monetary Policy

TIER 4 May 20, 2026

A Washington Post op-ed (excerpted) framing the central dilemma for new Fed chair Warsh: the debate shifted from how fast to cut rates amid AI-productivity optimism to confronting a 1979-style stagflationary shock from tariffs and an Iran-driven oil spike. Cochrane sharpens the choice — fight resurgent inflation by raising rates and incurring Trump's wrath, or 'look through' the shock and anger inflation-weary households. Substantive policy analysis with his signature framing, though truncated to an op-ed teaser with the full version pending.

Trade, Tariffs & Price Controls

0 tier-5 · 2 tier-4

These pieces apply Econ 101 discipline — accounting identities, budget constraints, and incentives — to two perennial interventionist temptations. On tariffs, Cochrane uses correlation-vs-causation, accounting identities, and repeated-game theory to show the prized foreign-investment "commitments" are inseparable from a larger trade deficit, and that bludgeoning allies erodes cooperation the US needs against China. On price controls, he delivers a rigorous rebuttal of "temporary, targeted" rent and energy controls grounded in budget constraints, reframes housing supply far beyond construction, and warns that economists pandering to their political team is its own hazard. The cluster matters as a clinic in seeing through intervention rhetoric to who actually pays.

Price Control Apologia

TIER 4 Nov 16, 2025

Responding to a NYT op-ed by Neale Mahoney and Bharat Ramamurti favoring 'temporary, targeted' rent and energy price controls, Cochrane delivers a rigorous Econ 101 rebuttal grounded in budget constraints and incentives: every dollar of relief to one party is a burden plus deadweight loss on another, rent control is just a tax on landlords funding incumbent tenants, and it fixes housing quantity while worsening mobility, opportunity, and equity. He reframes 'supply' beyond construction (freeing up underused units, removing capital-gains and mortgage lock-in, deregulating short-term and shared rentals) and argues 'temporary/targeted' controls reliably become permanent, closing with a warning about economists pandering to their political team. Substantive, well-argued, but a polemical reaction piece rather than an original framework.

Trump on Tariffs and Investment

TIER 4 Feb 3, 2026

Dissecting Trump's WSJ op-ed, Cochrane applies three lenses—correlation vs. causation, accounting identities, and repeated-game theory—to argue tariffs lack evidence of promoting growth, and that the prized foreign-investment 'commitments' are inseparable from a larger trade deficit because foreigners can only invest dollars they earn by selling us more than they buy. He credits the 'economic statecraft' coercion angle that economists underrated, but warns tariffs are hard to remove and that bludgeoning allies erodes the cooperation the US will need against China. A clear, substantive trade-economics teaching piece.

Growth, Living Standards & the Case for Markets

0 tier-5 · 1 tier-4

Cochrane's affirmative, evidence-dense case for economic growth and market-driven living standards, set against romanticized accounts of the past. Using levels data rather than rates, he dismantles 1950s nostalgia — real GDP per capita ~3.7x higher, a decade more life expectancy, far better houses and cars, and "good union jobs" that excluded women and minorities under a 91% top tax rate that collected little after loopholes. The cluster matters as a corrective explainer for debates over growth, inequality, and whether things were better before.

Misplaced Nostalgia

TIER 4 Feb 11, 2026

Reprinting a Coolidge Review essay, Cochrane dismantles 1950s nostalgia with levels data: real GDP per capita is ~3.7x higher today, 100 million jobs were added, houses and cars are far better, life expectancy rose a decade, and the era's 'good union jobs' excluded women and minorities while 91% top tax rates collected little after loopholes. The thesis—that 2025 (with 2024 second) is the best year for the US economy—is a useful, evidence-dense corrective explainer on growth, inequality, and living standards.

Financial Regulation & Bank Runs

0 tier-5 · 1 tier-4

Cochrane's long-running thesis on financial regulation: systemic risk comes from run-prone short-term liabilities, not asset riskiness, which is why tech firms holding risky assets pose no systemic threat (they are equity-financed) while banks invite runs and bailouts via short-term debt. He argues incoming Fed chair Warsh should refocus regulation accordingly — the failure mode of 2008 and the reason Dodd-Frank fell short. The cluster (one keeper here, but a distinct policy domain) matters as the clearest articulation of his equity-financed-banking program.

Cochrane's framing — tech firms hold riskier assets but pose no systemic risk because they are equity-financed, while banks invite runs and bailouts via short-term debt — is a clear, useful articulation of his long-running equity-financed-banking thesis. Substantive but condensed to an op-ed teaser.
