Evan Koenig on the Case for Nominal GDP Targeting

Episode Summary

Executive Summary: Evan Koenig argues that nominal GDP targeting is a simpler, more intuitive, and more stable monetary framework than inflation targeting because it anchors overall nominal income rather than just prices. He says it improves financial stability, better handles supply shocks, supports full employment, and would have helped the Fed avoid errors in recent crises and framework reviews.

Main Topics: What nominal GDP targeting is (Priority: 5/5): Koenig defines nominal GDP targeting as setting a target path or growth rate for total nominal spending/income, such as NGDP or nominal GDI, over a chosen horizon. Why he became interested in it (Priority: 4/5): His interest began in the late 1980s when discussions of inflation targeting led him to realize that households care most about predictable nominal income flows when they have fixed nominal obligations. Critique of the Fed's 2019-2020 framework review (Priority: 5/5): He argues the prior framework review was too narrow, focused mainly on demand shocks, Calvo price stickiness, and the zero lower bound, while ignoring wage stickiness, debt contracts, and financial stability. Arguments for nominal GDP targeting (Priority: 5/5): Koenig emphasizes simplicity, better communication, stronger inflation anchoring, improved employment outcomes under wage frictions, and built-in forward guidance at the zero lower bound. Financial stability and risk-sharing (Priority: 5/5): He argues NGDP targeting stabilizes debt burdens by making real debt burdens countercyclical, reducing default risk and helping mimic state-contingent debt contracts in incomplete markets. Supply shocks and macro stabilization (Priority: 4/5): Unlike inflation targeting, NGDP targeting accommodates supply shocks while preventing them from cascading into financial crises and secondary demand collapses. Real-time monitoring and policy lessons (Priority: 4/5): Koenig uses NGDP and related aggregates to assess whether policy is restrictive, citing COVID-era and post-GFC patterns as examples of how nominal spending paths reveal policy mistakes.

Key Arguments: Nominal GDP targeting is more intuitive than inflation targeting because households and firms care about predictable nominal income, especially when obligations are fixed in nominal terms. The previous Fed framework review was too narrow: it focused on demand shocks, one sticky-price model, and ignored debt, wages, and financial-stability channels. NGDP targeting is not in conflict with the Federal Reserve Act; Koenig says it is consistent with the Fed's dual mandate and its emphasis on dollar liquidity growth. NGDP targeting can be implemented in a Taylor-rule-like way, so it is not operationally alien or too weird for policymakers or the public. It improves financial stability by reducing the chance that households' real debt burdens spike during recessions and by restraining irrational exuberance during booms. It handles supply shocks better than inflation targeting by allowing prices to adjust while stabilizing nominal income, which can prevent first-round shocks from becoming financial crises. It can reduce the probability of hitting the zero lower bound because financial stress tends to depress the natural real interest rate, and NGDP targeting lessens that stress. Compared with inflation targeting, NGDP level targeting provides a stronger medium-term anchor for inflation expectations because it stabilizes the growth path of nominal spending, not just price changes.

Data Points: Fed framework review focus: 2019-2020 - The discussion centers on the Fed's first framework review and why NGDP targeting was largely excluded. Duration of Koenig's Fed career: late 1980s to a few years ago - He spent his entire Federal Reserve career at the Dallas Fed. Potential growth plus inflation benchmark: 4% nominal GDP growth - For the post-COVID recovery, the speakers note a 2% inflation target plus 2% long-run real growth implies a 4% NGDP path. Latest GDP data referenced: through Q2 2024 - Koenig says the latest available GDP and GDI data at the time only ran through the second quarter of 2024. Nominal spending growth in 2024: excess of 5% - He argues nominal spending remained too strong in early 2024 to be consistent with truly restrictive policy. Federal Reserve target inflation: 2% - Used repeatedly as the inflation target in the Fed's framework and in his benchmark for nominal GDP growth. Long-run real growth assumption: 2% - Koenig uses 2% as a rough estimate of long-run potential real growth in the economy. Recovery observation for COVID: Q3 2021 - He notes nominal GDP had returned to the pre-COVID target path by the third quarter of 2021, even though policy was still highly accommodative. Policy action timing after COVID: March 2022 rate hikes - He says the Fed did not begin tightening interest rates until March 2022 despite nominal GDP already having recovered. Asset purchases tapering: November 2021 - The FOMC only slightly reduced asset purchase pace then, leaving policy very accommodative.

Pivotal Quotes: "what's important to me is my flow of nominal income" — Evan Koenig: He explains why fixed nominal obligations made nominal income stability the core intuition behind nominal GDP targeting. "the committee seeks to explain its monetary policy decisions to the public as clearly as possible" — David Beckworth citing the Fed statement: Used to contrast the Fed's stated commitment to clarity with the confusion surrounding the current framework. "I think that the worst sort of policy environment is when you're up against the zero lower bound" — Evan Koenig: He closes by arguing NGDP targeting helps avoid severe downturns and the ZLB trap by reducing financial stress.

Implications: The episode suggests the Fed should seriously evaluate NGDP targeting in its framework review as a clearer, more robust rule that better protects households, financial stability, and policy credibility, especially when shocks are supply-driven or rates approach the zero lower bound.
