Rethinking Shelter’s Role in Monetary Policy: An Unorthodox View

In a recent whitepaper titled "Housing Policy, Inflation, and Monetary Policy: An Unorthodox View," Gabriel Chodorow-Reich (Harvard University) and Neil Mehrotra (Federal Reserve Bank of Minneapolis) challenge the traditional frameworks central banks use to address housing-driven inflation. As rents and shelter costs became primary drivers of inflation in the post-pandemic era, the authors argue that the current emphasis on these metrics may be misplaced.

The Case for "Looking Through" Shelter Inflation

A central argument of the paper is that monetary policy may be more optimal when it places less weight on shelter inflation than its actual share in consumer expenditure. This "unorthodox" conclusion stems from three key market characteristics:

• Sticky Rents: Official measures of rent often lag behind market realities; research shows an average lag of roughly 26 months in rent adjustments.

• Inelastic Supply: Housing supply is structurally slow to respond to demand shifts, meaning interest rate changes have a limited immediate impact on availability.

• Search Costs as Rationing: In housing, search frictions—the time and effort spent finding a home—act as a natural mechanism for rationing excess demand.

The authors conclude that because search frictions mitigate the welfare losses of demand imbalances, the Federal Reserve should focus more on stabilizing the non-housing sectors of the economy rather than aggressively targeting shelter inflation.

Critiquing Current Measurement (OER)

Chodorow-Reich and Mehrotra also highlight a significant flaw in the U.S. measurement of shelter costs. The current "Owners' Equivalent Rent" (OER) approach uses rental market data to estimate the cost of homeownership, but this often ignores the direct impact of mortgage rates and house prices.

For instance, between 2022 and 2024, mortgage rates doubled, significantly increasing the cost of living for new buyers. Yet, because OER focuses on rental values, these increased ownership costs were not directly reflected in official inflation figures. The authors suggest a transition toward a "cost-of-living" index that capitalizes and smooths these pecuniary costs over time to better reflect household purchasing power.

The Net Impact of Monetary Policy

The paper also addresses whether lower interest rates truly make housing more affordable by reducing builder financing costs. While lower rates do reduce costs for developers, the authors find that the resulting increase in demand for housing outweighs these supply benefits. On net, more accommodative monetary policy tends to increase the overall cost of housing.

Conclusion

By reevaluating the relationship between interest rates and housing, Chodorow-Reich and Mehrotra suggest that monetary policy should "look through" certain housing cost spikes. Instead of maintaining a restrictive policy solely to curb shelter inflation, they argue for a more balanced approach that accounts for the unique search frictions and supply constraints inherent in the housing market.
