Carola Binder on Political Pressure and the Twin Deficits of Central Banking

Episode Summary

Executive Summary: Kerala Binder argues that central banks face rising populist pressure because they are both poorly understood and insufficiently trusted. Drawing on cross-country evidence and New Zealand’s policy evolution, she suggests nominal GDP level targeting could improve communication, accountability, and legitimacy while preserving a stable nominal anchor—making a proactive framework change preferable to letting political pressure force change later.

Main Topics: Binder’s path into macroeconomics (Priority: 2/5): Binder describes moving from math to economics through policy work during the Great Recession, then choosing macro at Berkeley because of the Romers’ U.S. macro history course and the policy intensity of the post-2008 environment. Why central banks are unpopular by design (Priority: 5/5): The discussion centers on Rogoff’s framework: independent central bankers are meant to be more inflation-averse than the public, which creates a deliberate tendency toward politically unpopular short-run policy choices. The 'twin deficits' of central banking (Priority: 5/5): Binder explains Andy Haldane’s idea that central banks face deficits of understanding and trust. Survey evidence shows the public often lacks knowledge of central banks’ targets, leadership, and recent inflation, and trust remains low. Political pressure and populism across countries (Priority: 5/5): Binder summarizes her 118-country dataset built from narrative reports, showing political pressure on central banks is widespread and usually favors easier monetary policy. Countries with nationalist or populist executives tend to experience more pressure. New Zealand as a warning case and model (Priority: 5/5): New Zealand’s move from pure inflation targeting to a more flexible framework, then to a dual mandate and committee structure, illustrates how political coalitions can reshape central bank design—suggesting central banks should adapt proactively. Why nominal GDP targeting could help the Fed (Priority: 5/5): Binder argues NGDP level targeting could be easier to communicate, align with observed U.S. nominal GDP trends since 2012, reduce reliance on uncertain concepts like U-star and Phillips-curve debates, and better match how households think about inflation. Central bank communication and survey evidence (Priority: 4/5): The conversation closes with Binder’s broader research on inflation expectations, sticky information, and Fed communication. She notes that press conferences raise awareness but may not change expectations much, and that SEP dots are hard for the public to interpret.

Key Arguments: Central banks must care about popularity because political actors can ultimately alter mandates, governance, or independence. Low public understanding and low trust weaken central bank legitimacy and make institutions more vulnerable to populist attack. Political pressure on central banks is real, measurable, and usually pushes toward easier monetary policy. When central banks resist political pressure, inflation can still rise as credibility erodes and expectations adjust. New Zealand’s reforms show that political pressure can force framework change after the fact; central banks should preemptively modernize instead. Nominal GDP level targeting offers a clearer, more communicable alternative to inflation targeting or dual-mandate interpretation, especially when inflation and unemployment concepts are politically contentious. A single explicit quantitative target reduces room for political interference and simplifies explanations to Congress and the public. Households often interpret inflation through a cyclical lens, so NGDP targeting may align better with public intuition than inflation targeting. Survey evidence suggests some consumers revise inflation beliefs sharply after repeated questioning, indicating that measured expectations can be noisy and sample-dependent. Fed communication tools may generate awareness without substantially improving expectation formation, so simplifying the policy framework may matter more than adding more speeches.

Data Points: Countries in Binder’s political-pressure dataset: 118 - Cross-country panel assembled from Economist Intelligence Unit and Business Monitor International reports Share of pressure episodes aimed at easier policy: >90% - Most recorded political pressure on central banks was for looser monetary policy Public knowledge of the Fed’s inflation target: 1/4 of respondents - In Binder and a former student’s Amazon Mechanical Turk survey, only about one-fourth correctly knew the Fed’s 2% target Correct identification of the Fed chair in survey: 2/3 of respondents - Survey participants were given multiple-choice options; two-thirds correctly picked Janet Yellen at the time New Zealand inflation-target range: 0% to 2% - Original price-stability definition under the Reserve Bank of New Zealand Act of 1989 Year of New Zealand electoral reform: 1996 - Shift from first-past-the-post to mixed-member proportional representation increased coalition politics Year of New Zealand coalition reforms: 2017-2018 - Coalition agreement led to Reserve Bank reforms, including a dual mandate and a monetary policy committee U.S. nominal GDP trend: ~4% annual growth path since 2012 - Binder notes U.S. nominal GDP appears to track a near-linear 4% path over the post-2012 period New York Fed panel conditioning effect on inflation expectations: ~4 percentage point downward revision - Repeated survey respondents revised inflation expectations substantially after first exposure Frequency gap in Michigan survey repeat responses: 6 months - Used in Binder’s discussion of sticky-information evidence Frequency gap in New York Fed survey repeat responses: 1 month - Monthly panel data reveal more frequent expectation revisions than low-frequency data suggest

Pivotal Quotes: "central banks are unpopular by design" — Kerala Binder: Binder summarizes the Rogoff-style argument that conservative, independent central bankers will often choose policies that are short-run politically unpopular but long-run stabilizing "the status quo is so unpopular and precarious that a new target would do more good than harm for central bank credibility" — Kerala Binder: Her core thesis on why nominal GDP level targeting could be a proactive response to populist pressure "the time is better now" — Kerala Binder: Her argument that the political and communication environment in the 2020s makes a framework shift more attractive than in 2011

Implications: Binder’s analysis suggests central banks should simplify frameworks, improve legitimacy, and reduce vulnerability to populism by adopting clearer targets like NGDP level targeting before political pressure forces change.
