# Source literature boundary memo

## Research question

Across retrieved source-level receipts for minimum_wage_employment, which metrics, settings, or contrasts differ versus remain null/mixed, 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

  - Population: low-skilled population groups in US states
  - Policy/exposure/practice: relatively large state minimum wage increases (defined as those exceeding $1) enacted between January 2013 and January 2015
  - Comparator/reference: smaller minimum wage increases and increases linked to inflation indexation provisions

## Source synthesis

Bounded signal: minimum wage employment is only a source-level context map; the selected receipts do not establish one pooled effect.

This receipt-backed scoping note has one bounded signal: minimum_wage_employment shows directional estimates with context limits across this 5-source primary bundle (2011-2018). Grouped by direction: directional estimate: 1 receipt(s) | economic/context only: 1 receipt(s) | other/mixed: 3 receipt(s). The source facts cover 5 population 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 heterogeneous policy/setting map, not a unified pooled economics claim. Concrete contrast: directional estimate: Are the Effects of Minimum Wage Increases Always Small? New Evidence from a Case Study of New York State: associated with a 20.2% to 21.8% reduction in the employment; economic/context only: 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...; other/mixed: Revisiting the Minimum Wage—Employment Debate: Throwing Out the Baby with the Bathwater?: teen employment elasticities near −0.15. Concrete source-level examples: relatively large minimum wage increases (defined as those exceeding $1) reduced employment among low-skilled population groups by just over 1 percentage point; teen employment elasticities near −0.15; renders the employment and hours elasticities indistinguishable from zero.

## Directional grouping

- directional estimate: minimum_wage_employment is the policy, exposure, method, or practice being measured; the label is not an efficacy verdict.
- reference/comparator contrast: minimum_wage_employment is the reference side of the extracted contrast; interpret only within that metric.
- economic/context only: the receipt reports cost, market, prevalence, policy, or institutional context rather than a policy-effect estimate.
- descriptive/modeling: the receipt reports modelling or prediction rather than a policy-effect estimate.
- null/mixed or other/mixed: the extracted finding is null, mixed, or not directionally interpretable.

- economic/context only: 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 population groups by just over 1 percentage point
- other/mixed: Revisiting the Minimum Wage—Employment Debate: Throwing Out the Baby with the Bathwater? — teen employment elasticities near −0.15
- other/mixed: Do Minimum Wages Really Reduce Teen Employment? Accounting for Heterogeneity and Selectivity in State Panel Data — renders the employment and hours elasticities indistinguishable from zero
- directional estimate: Are the Effects of Minimum Wage Increases Always Small? New Evidence from a Case Study of New York State — associated with a 20.2% to 21.8% reduction in the employment
- other/mixed: Credible Research Designs for Minimum Wage Studies — A data-driven LASSO procedure that optimally corrects for state trends produces a small employment elasticity (–0.01).

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.
 The signal is purely descriptive of effect-direction heterogeneity; 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

A stronger memo needs a matched design that reduces this bundle's heterogeneity: 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 mixing other source context.
