# Source literature boundary memo

## Research question

Across retrieved source-level receipts for minimum_wage_employment, which metrics, settings, or contrasts carry directional support versus caveat evidence, and what matched design remains untested?

## Selection criteria

The source-literature selector kept minimum_wage_employment because the candidate bundle met the public source rule: 5 citable papers, 5 distinct fact-backed source identities, topic-overlapping source facts, and enough shared scope to compare metric/context disagreement. It excludes duplicate reports, metadata-only title matches, off-topic papers, and sources without fact-level extraction before treating the bundle as a coherent scoping front rather than proof of a policy or market conclusion.

## Boundary map

## Source synthesis

Bounded signal: minimum wage employment has direction-bearing evidence limited to employment effects; this is bounded to those metrics and settings.


## Evidence matrix

Matrix guard: effect-bearing rows below are metric-specific source facts, not a pooled comparison; context-only rows are excluded from effect support.

This receipt-backed scoping note is a multi-outcome boundary map for minimum_wage_employment: directional estimates with context limits across this 5-source primary bundle (2011-2018). Evidence role grouping: direction-bearing receipts: 3; metric-scope caveat receipts: 0. The source facts cover 5 population/setting context(s) and 5 policy/exposure/practice context(s), so this is a scoping signal about where metrics diverge, without establishing a causal, policy-prescriptive, market-generalized, or pooled econometric claim. The listed estimates remain source-specific across metrics and settings; they are not pooled or averaged. This is a separated policy/setting map, not a unified pooled economics claim. Named setting scope includes 16- to 29-year-olds who do not have a high school diploma, U.S. states, teen employment 1979-2014, low-skilled population groups in US states, teen, and teens. Substantive signal: direction-bearing evidence is limited to employment effects. Coverage balance: employment effects (3 of 3 direction-bearing receipts) is represented more than once; that is a scope imbalance to disclose, not stronger evidence for the topic. Within-vs-across outcome rule: direction-bearing rows are only compared within employment effects; unrelated receipt families are not treated as one outcome. Outcome families named here are employment effects; this is not one harmonized endpoint. Concrete contrast: directional association: THE SHORT‐RUN EMPLOYMENT EFFECTS OF RECENT MINIMUM WAGE CHANGES: EVIDENCE FROM THE AMERICAN COMMUNITY SURVEY: relatively large minimum wage increases (defined as those exceeding $1) reduced employment among low-skilled...; non-directional caveat: Revisiting the Minimum Wage—Employment Debate: Throwing Out the Baby with the Bathwater?: teen employment elasticities near −0.15.

## Evidence role definitions

- directional association: minimum_wage_employment is the policy, exposure, method, or practice linked to the named metric; the label is not an effect-size estimate or efficacy verdict.
- metric-scope caveat: the receipt constrains the directional scope to the named metric rather than the broader outcome set.
- non-directional caveat: the extracted finding is not directionally interpretable for the named metric.

Evidence role summary: direction-bearing receipts: 3; metric-scope caveat receipts: 0.
Direction labels for audit: non-directional caveat: 2 receipt(s) | directional association: 3 receipt(s).

Specific moderators in this bundle are outcome type (Employment elasticity; employment and hours elasticities; employment elasticities), population/indication (16- to 29-year-olds who do not have a high school diploma; U.S. states, teen employment 1979-2014; low-skilled population groups in US states; teen; teens), study design/evidence type (primary).

## Context separation

Population/settings are separated as receipt context: 16- to 29-year-olds who do not have a high school diploma, U.S. states, teen employment 1979-2014, low-skilled population groups in US states, teen, and teens. The selected receipts group because each carries a fact-level extraction for minimum_wage_employment; they separate by context (other source context) and metric, so they are not interchangeable evidence for one pooled claim.

## Boundary limits

Source-literature boundary for minimum_wage_employment: the listed sources define one bounded, context-dependent signal across separate source contexts. This memo does not claim causality, policy prescription, a pooled elasticity estimate, or a market-generalized effect across the sources.
 Material limitations: small 5-source bundle; no pooled estimate is possible; method/model receipts without direct effect estimates are context only; outcomes are not harmonized across studies.
 The signal is purely descriptive of source-level direction and scope; it cannot support a causal, policy-prescriptive, or pooled elasticity inference, and pooling across these designs would be inappropriate.
 Routing domain `business_research` is publication-lane metadata only; the source scope here is defined by the selected minimum_wage_employment receipts.

## Next gaps

Resolve the coverage imbalance by adding or swapping receipts so employment effects is not over-represented relative to the other named metrics inside the same scoping map.
A stronger memo needs a matched design that reduces this bundle's scope spread: hold metric=employment elasticities constant, compare policy/exposure=relatively large state minimum wage increases (defined as those exceeding $1) enacted between January 2013 and January 2015 against a clearly matched reference group, and test it in a setting adjacent to but not duplicating low-skilled population groups in US states.
If minimum_wage_employment is promoted beyond a scoping note, the next run should select sources sharing one context family rather than spanning other source context.
