Definitions and precise research target

Complete editorial problem. Fix an electoral setting and a verified measure $q_j$ of incumbent $j$'s public-service performance. An information intervention $z$ delivers a declared message through a specified channel before an election. Let $B_i(z)$ be voter $i$'s belief about performance, $V_i(z)$ the vote choice, and $G_{jT}(z)$ subsequent service provision. Define belief, vote, and service effects separately, including $\tau_G=E[G_{jT}(1)-G_{jT}(0)]$. Accountability additionally requires evaluating how support responds to performance, rather than an undirected change in incumbent vote share. Orthogonal message, source-credibility, coordination, or alternative-candidate variations can distinguish information failures from distrust, identity preferences, clientelistic incentives, and inability to coordinate. State assumptions permitting those mechanism interpretations. Account for message spillovers, selective exposure, turnout, and politicians' responses to anticipated disclosure. A null average vote effect can coexist with corrected beliefs or subgroup effects; it does not show that information never matters. The proposed problem is to identify conditions yielding durable accountability and service improvements. Existing coordinated trials provide substantial answers for their tested designs; an exact primary open-question paragraph for the combined catalogue formulation was not verified.

Definitions and admissible scope. Define $V_i\in\{0,1,\varnothing\}$ as incumbent support, alternative support, or nonparticipation; assigning turnout a separate code avoids conditioning on post-treatment voters. Verified incumbent performance $q_j$ is measured before messages and on a common scale. For a binary high/low performance category, an accountability contrast is $\kappa=[E(V^I(1)-V^I(0)\mid q=H)]-[E(V^I(1)-V^I(0)\mid q=L)]$, where $V^I$ is the incumbent-vote indicator among all eligible voters. It is heterogeneity of information effects, not a causal effect of changing performance. Later service $G_{jT}$ is measured at jurisdiction level and may depend on election outcomes and politicians' anticipation. Belief, vote, turnout, and service estimands are distinct. Take a fixed eligible-voter cohort and jurisdiction assignment law. Define $V_i^I(z)=1\{V_i(z)=1\}$, so nonvoters contribute zero rather than disappearing. Belief effects use a fixed score, for example the mean posterior probability of high performance; vote and service effects use their own scales. Specify dates of information, election, and service follow-up $T$, source accuracy and delivery, performance categories, and cluster exposure mappings. The source's existing average vote evidence is a constraint on relevant model interpretations, while the joint identified set of belief, turnout, accountability-heterogeneity, and later-service effects is the editorial target. Subgroup contrasts require common design support and no claim that observed performance was randomized.

Variants and assumption changes

  1. Typical message replication (source-based scope): replicate comparable nonpartisan performance messages with preregistered pooled effects. The coordinated trials already estimate average voter behavior effects; their null finding is evidence, not proof that every information design fails.
  2. Coordination and credible alternatives (editorial): independently vary trusted source, community discussion, and alternative-candidate information and follow subsequent service provision. Cluster assignment and politician spillovers must be defined before mechanism claims.

Common conventions: Source mathematical conventions

These conventions apply to each entry unless explicitly replaced.

Models and identification. A primitive model $m$ specifies all probability laws, feasible choices, information, equilibrium and measurement rules used by its target. The admissible class $\mathcal M$ is fixed independently of outcomes. If $P_O(m)$ is its observable probability law and $\tau(m)$ the target, its identified set at observable law $P$ is \[ \mathcal I_\tau(P)=\{\tau(m):m\in\mathcal M,\ P_O(m)=P\}. \] Point identification means that this set is a singleton. An empty set signals incompatibility of data and assumptions. Coordinate bounds need not describe the joint set. Bounds are sharp only if every retained target is attainable or arbitrarily approachable by compatible models. Finite bounds require explicit restrictions on unobserved quantities; unrestricted confounding, hidden wealth, extrapolation or arbitrary equilibrium selection can yield uninformative sets.

Causal interventions. A potential outcome $Y_i(p)$ is the outcome under a complete policy regime $p$, including timing, financing, information and market spillovers. The target population and units are fixed before treatment. With interference, use the complete assignment vector or a justified exposure mapping; individual no-interference notation alone cannot identify an economy-wide intervention. A difference of mean potential outcomes does not require the cross-world joint distribution. Conditioning on post-treatment migration, survival, enrollment or employment changes the estimand and needs separate justification.

Statistical statements. An estimator, confidence set, forecast or test specifies a sampling law, model class and loss/coverage criterion. Uniform $(1-\alpha)$-coverage means $\inf_{m\in\mathcal M}\Pr_m\{\tau(m)\in C_n\}\geq1-\alpha$, or an explicitly asymptotic version. The whole parameter space trivially has coverage, so informativeness requires a stated width, risk or power objective. A forecasting improvement is relative to a named benchmark, information set and evaluation population.

Equilibrium and optimization. An equilibrium comprises feasible plans, optimality, beliefs where needed, budget constraints and all market/resource clearing. The primitives or a stated benchmark define each correspondence $\mathcal E(p;m)$. Nonemptiness is assumed or proved, never inferred just from compact policy sets. A selected-equilibrium target uses a declared selection rule; a robust target quantifies over all permitted equilibria. Use suprema or infima unless attainment is established. An $\varepsilon$-optimal policy is feasible and within $\varepsilon$ of the finite optimum value. Report an empty feasible set separately.

Welfare and accounting. Normative utility, interpersonal normalization, social weights, numeraire, discounting and the use of public receipts are primitives. Behavioral utility need not coincide with the welfare criterion. Household welfare includes ownership income and rents once; adding profits again to compensating variation generally double-counts them. A monetary equivalent is defined by an explicit transfer and price convention, with monotonicity and range conditions. Average effects, mechanism contributions, transfers and welfare losses are different targets. Infinite sums require convergence and dynamic feasible plans require terminal or no-Ponzi conditions.

Source versions. A working-paper date, revision date and journal publication year are distinguished. A DOI for a journal version is not automatically the DOI of an earlier manuscript. Locators refer to the stated version and printed pages where specified. A metadata-only check does not verify a claim about a full-text conclusion. Every entry's source subsection narrows the provenance claim accordingly.

Information, accountability gradients, and anticipated disclosure

Problem ID: D72-527. Status: Unresolved. The following results concern declared restricted models.

A zero average vote effect can conceal accountability

The canonical target separates beliefs, incumbent support among all eligible voters, turnout, and later public services. Accountability is a response to verified performance rather than an undirected change in vote share. This attempt gives an exact example with a zero average vote effect and a maximal accountability contrast, then derives a politician's effort response to anticipated disclosure. These results are mechanism possibilities, not findings about any electorate.

Let incumbent performance be $q\in\{0,1\}$ with prior probability $\pi\in(0,1)$ of high performance. A voter supports the incumbent when their posterior probability $b$ exceeds an idiosyncratic threshold $c$, independently distributed with continuous cumulative distribution $H$ on the real line. No turnout decision is present in this first benchmark. Without information $b=\pi$; a perfectly credible disclosure reveals $q$, giving $b=q$. Thresholds and eligibility do not change under disclosure.

Proposition (Directed accountability without an average vote change): The disclosure effects by performance are $H(1)-H(\pi)$ for high performance and $H(0)-H(\pi)$ for low performance. Their difference is \[ \kappa=H(1)-H(0)\ge0. \tag{1} \] The average vote effect is $\pi H(1)+(1-\pi)H(0)-H(\pi)$. If $c$ is uniform on $[0,1]$, this average is zero while $\kappa=1$.
Proof: At posterior $b$, the supporting fraction is $H(b)$ by the threshold rule. Substitute the uninformed and informed beliefs and subtract. Under uniform thresholds, $H(0)=0,H(1)=1,H(\pi)=\pi$, proving both claims. The high-performance and low-performance effects, $1-\pi$ and $-\pi$, cancel after weighting by their population frequencies. ∎

Average beliefs also remain unchanged in this example: both before and after disclosure their mean is $\pi$. Yet the expected Brier error for predicting $q$ falls from ${\mathbb{E}}(q-\pi)^2=\pi(1-\pi)$ to zero. Thus a mean-belief null and an average-vote null can coexist with improved calibration and a strong performance gradient. A suitable evaluation should predeclare which of these objects it measures.

The contrast in (1) is heterogeneity of the disclosure effect across pre-message performance categories. It is not the causal effect of experimentally making an incumbent perform better. Randomizing information while measuring performance accurately identifies this contrast under its assignment and interference restrictions, without randomizing performance itself.

Credibility and political alternatives enter through separate primitives

Suppose a signal has known symmetric accuracy $a\in(1/2,1]$. With prior $\pi$, Bayes' rule gives \[ b_1=\frac{a\pi}{a\pi+(1-a)(1-\pi)},\qquad b_0=\frac{(1-a)\pi}{(1-a)\pi+a(1-\pi)}. \] The signal is high with probability $a$ under high actual performance and $1-a$ under low performance. Consequently the accountability contrast becomes \[ \kappa(a)=(2a-1)\{H(b_1)-H(b_0)\}\ge0. \tag{2} \] This follows by computing the two signal-mixture support rates and subtracting. At $a=1/2$ the signal is uninformative and the contrast is zero. At $a=1$ it reduces to (1).

Changing a source label identifies a credibility mechanism only if it changes perceived signal accuracy while leaving utility thresholds and delivery unchanged. A source could also alter identity attachments or participation incentives, changing $H$. Likewise, credible alternative candidates can shift thresholds even when beliefs about the incumbent do not move. Formula (2) distinguishes these primitives but does not identify them from a vote contrast alone. Validated belief elicitation and orthogonal experimental variation are needed to separate them.

For example, a weak observed performance gradient can arise either because $a$ is near one half or because $H$ is almost flat between the posterior values. The first corresponds to little informative updating; the second to voters whose choices are relatively insensitive to those beliefs. Both fit a small vote effect, while predicting different responses to more accurate information.

Anticipation changes the service-production margin

Now consider a separate effort game. Before performance is realized, the incumbent chooses $e\in[0,1]$, which makes high performance occur with probability $e$. Effort costs $ce^2/2$, $c>0$. Reelection has private value $R>0$. With public probability $d\in[0,1]$, a later disclosure reveals performance. Without disclosure the reelection probability is a constant $v_0$ with respect to an unobserved unilateral effort deviation. With disclosure, it is $H(1)$ or $H(0)$ according to performance. These probabilities are primitives of a reduced electoral rule, for example a pivotal-voter interpretation.
Proposition (Service effort under anticipated disclosure): The unique effort choice is \[ e^*(d)=\min\left\{1,\frac{Rd[H(1)-H(0)]}{c}\right\}. \tag{3} \] It is nondecreasing in disclosure probability and strictly increasing before saturation if $H(1)>H(0)$.
Proof: Expected incumbent payoff is \[ R\{(1-d)v_0+d[eH(1)+(1-e)H(0)]\}-ce^2/2. \] This is strictly concave in $e$. Its derivative is $Rd[H(1)-H(0)]-ce$, so truncating the unconstrained optimizer to $[0,1]$ gives (3). Since the numerator is nonnegative, the lower constraint is automatically respected. ∎

At $R=c=1$ with uniform thresholds, $e^*(d)=d$. Increasing anticipated disclosure from zero to one half increases expected performance from zero to one half in the model. A surprise message delivered after performance is realized cannot identify this anticipatory effort effect: it changes voters' information after the incumbent's choice. A long-run program that incumbents expect is a different intervention from a one-election surprise experiment.

The model fixes office value, effort costs and the electoral response rule. It does not include endogenous candidate entry, repression, strategic manipulation of measured services, or changing fiscal capacity. Such changes can reverse an extrapolation from (3), even if the one-election information contrast is identified accurately.

A coherent measurement and assignment design

For the catalogue's support outcome define $V^I={\mathbf1}\{\text{incumbent vote}\}$ for every eligible voter, with nonvoters contributing zero. Conditioning on realized turnout instead can change the denominator under treatment. A separate turnout indicator identifies whether information changes participation. Belief losses should use independently verified performance and a frozen elicitation scale.

If disclosure is randomized by jurisdiction, estimate the joint vector of belief, turnout, support and service contrasts at that level, with baseline cohort weights. Spillovers between jurisdictions require either a complete policy-vector estimand or a justified exposure mapping. Subgroup accountability contrasts need assignment support in both pre-message performance categories. No amount of individual sample size removes dependence created by one common incumbent response.

The constructed null example, noisy-signal formula and effort theorem are complete within their assumptions. The unresolved empirical task is identifying which credibility, preference, coordination and anticipation restrictions fit a real setting and whether service gains persist. Existing trial nulls do not establish universal failure, and this illustrative model does not establish universal success.

Completion Estimate

50%

This is a post hoc, heuristic estimate for the full catalogue target. The attempt proves that average vote and belief nulls can coexist with strong performance accountability and derives noisy-credibility and anticipated-service-effort responses. Durable accountability still needs credible belief and turnout measurement, orthogonal mechanism variation, politician spillover and anticipation designs, and validated later-service evidence.
