Data & methods
Who is represented and how the evidence is constructed
The site combines survey evidence, a randomized information experiment, enacted legislation, and successive CBO projections. This page documents the samples, construction, and limits.
Survey samples
Three samples answer different parts of the study
Participants were recruited in the United States through Prolific prescreeners. The labels below identify screened research samples, not probability samples of the full investing public or electorate.
N = 985Bond investors
U.S. residents recruited through Prolific’s government-bond ownership prescreener. Eligibility relies on self-reported ownership; the survey does not observe position size or trading activity.
Used for valuation, sustainability, portfolio responses, and the randomized information treatment.N = 1,001Registered voters
U.S. residents recruited through Prolific’s registered-voter prescreener. The sample is useful for studying the political relevance of fiscal beliefs but is younger and more educated than the U.S. adult population.
Used for valuation, sustainability, and reported voting decisions.N = 247Graduate training in economics or finance
Respondents whose highest completed degree is a master’s or doctoral degree in economics or finance.
Used as a trained comparison group for valuation and sustainability beliefs. Representativeness
The voter sample is broadly similar to U.S. benchmarks on sex and race, but younger and more educated
Both samples are younger than the U.S. adult population; bond investors are also more male and more often employed full time.

Benchmark: U.S. adult comparisons reported in the working paper. Age, sex, and race use Census benchmarks; employment uses CPS benchmarks; education uses adults aged 25 and older. Race and employment categories are only approximate matches to Prolific’s fields. Values are rounded, so grouped shares may not sum exactly to 100. Dashes indicate unavailable comparisons.
01Main estimates are unweightedThe primary survey analyses report sample estimates rather than claiming population-representative prevalence.
02Voter weighting is a robustness checkFor the 994 voters with complete fields, post-stratification weights rake age and sex to U.S. adult margins and education to the available margin for adults aged 25 and older. Valuation shares move by no more than 1.1 percentage points, and the ordering of sources is unchanged.
03Weighting has limitsObserved-demographic weights cannot correct selection on unobserved characteristics, including attention to fiscal issues.
Recruitment, screening, and sequence
Recruitment and screening determine who enters each sample
The survey screens for prior awareness of the government-debt question, records baseline beliefs and behavior, elicits valuation mechanisms, randomizes information treatments, and then measures sustainability beliefs and intended decisions.

24.5%voter awareness screen-out

01BaselinePerceived debt/GDP, debt-sustainability concern, and sample-specific reports of past behavior.
02Valuation moduleWhich sources support government debt value and the relative importance assigned to each.
03Randomized informationRespondents are assigned to control, debt-trajectory information, safe-asset vignette, or rollover vignette groups.
04Sustainability and intentionsCrisis beliefs, sustainable debt assessments, and prospective Treasury intentions where applicable.
Exclusions: most exclusions reflect incomplete responses. Criteria requiring judgment remove 1.9% of eligible investors and 0.8% of eligible voters. The debt/GDP cap removes 3 of 250 respondents with graduate training in economics or finance.
Fiscal expectations data
One expected fiscal path for every quarter
The project aligns enacted legislation with successive CBO projections to reconstruct the expected path of taxes, spending, primary deficits, and debt from each quarterly vantage point.
LegislationBudget effects of new laws
Revenue and outlay effects are assigned by fiscal year and budget component.
Identifies discrete fiscal news.CBO baselines and outlooksOfficial expected paths
Successive publications provide the contemporaneous budget path used at each forecast date.
Tracks how the outlook changes over time.Realized outcomesLater fiscal data
Projected primary-deficit paths are compared with subsequently realized values at matched horizons.
Measures projection gaps, not a pure forecast error.Professional forecasts and pricesPrivate expectations and valuation
The analysis links fiscal news to forecast revisions and Treasury-market valuation.
Connects fiscal news to beliefs and prices.
