What is the total local economic impact of sustained workforce investment in Honolulu when earnings gains recirculate through the local economy, compared with no intervention?
Workforce Understory Episode: Episode Four — Mobility Through Lifelong Learning
Geography: Honolulu County
Topic: STARs, upskilling, workforce investment, and local economic impact
The takeaway
This modeled scenario builds on the additional earnings generated by an annual workforce investment supporting Honolulu STAR workers into higher-wage roles.
Applying a 1.4 local economic multiplier, the model estimates that those earnings gains could produce approximately $2 billion in additional cumulative economic activity by 2036.
The impact accelerates in the later years as higher earnings from earlier worker cohorts continue circulating through the economy while newly supported cohorts begin generating gains of their own.
The model suggests that sustained worker advancement could create benefits far beyond individual paychecks, generating additional demand for Honolulu businesses, workers, and communities.
What this visualization shows
This visualization compares cumulative economic activity in Honolulu County under two scenarios from 2027 through 2036:
Economic activity without the modeled workforce investment
Economic activity with sustained annual investment in upskilling and higher-wage employment
The model begins with the additional worker earnings projected in the previous visualization. It then applies a 1.4 local economic multiplier to estimate the broader effect as part of that income is spent and recirculated through Honolulu’s economy.
A multiplier of 1.4 assumes that each dollar of additional worker earnings generates approximately 40 cents in further economic activity beyond the initial income gain.
That additional activity could occur when workers spend more on housing, food, transportation, childcare, healthcare, entertainment, and other goods and services. The businesses receiving that revenue may then purchase additional supplies, hire workers, increase employee hours, or make other expenditures of their own.
The cumulative impact grows more quickly over time because each new cohort is added to workers supported in previous years. Earlier participants are assumed to continue earning and spending more while later cohorts begin contributing additional gains.
This is a prospective model rather than a record of observed economic activity.
Its results depend on the assumptions used in the underlying earnings model and on how much additional income remains within Honolulu’s economy. The projected total represents estimated cumulative economic activity, not government revenue, business profit, or a guaranteed financial return to the organizations funding the intervention.
Why this matters
The benefits of workforce investment do not necessarily end with the workers who receive training or move into higher-paying roles.
When earnings increase, households may have more capacity to meet essential needs, reduce financial instability, and purchase goods and services. Those expenditures can support other businesses and workers, creating an economic effect beyond the initial wage gain.
Honolulu may be especially well positioned to retain and recirculate that spending.
Oʻahu has Hawaiʻi’s largest consumer market, the greatest concentration of employers, and the state’s most extensive network of local suppliers and service providers. Workers may therefore be able to purchase a larger share of what they need within the county rather than directing spending toward businesses located elsewhere.
That could mean Honolulu’s actual multiplier differs from the 1.4 assumption used in the model. A denser economy with deeper local supply chains may retain more spending, while reliance on imported goods, nonlocal ownership, and high housing costs may still cause substantial economic leakage.
The possibility of a stronger multiplier reinforces the economic-development case for investing in Honolulu. Workforce programs may produce more reliable returns where destination jobs, employers, training providers, and supporting infrastructure already exist.
But concentrating investment where the economy is strongest creates an equity dilemma.
The same conditions that make workforce investment more likely to succeed in Honolulu are part of the geographic imbalance documented throughout the Workforce Understory. Directing resources primarily toward Oʻahu could strengthen an already dominant labor market while leaving Neighbor Island communities with fewer living-wage pathways and less capacity to generate their own economic growth.
The strategic question is therefore larger than where an investment produces the greatest immediate return. Hawaiʻi must also consider whether workforce funding reinforces the existing geography of opportunity or helps build stronger regional economies across the state.
This evidence invites Hawaiʻi to ask:
How can workforce investment capture Honolulu’s strong economic returns without deepening the divide between Oʻahu and the Neighbor Islands?

Questions this visualization raises
What is the source of the 1.4 local economic multiplier? Was the multiplier developed specifically for Honolulu County?
Could Honolulu’s larger consumer base and deeper supply chains produce a higher multiplier?
How does Honolulu’s appropriate multiplier compare with those of Hawaiʻi, Maui, and Kauaʻi counties?
How much of each additional dollar earned is likely to be spent within Honolulu?
How much spending leaks out through imported goods, online retailers, nonlocal ownership, taxes, or savings?
Do different industries produce different levels of local recirculation?
Would wage gains in Healthcare, Construction, Technology, Government, or Hospitality have the same local impact?
Which industries purchase the greatest share of their goods and services from local suppliers?
Are the employers receiving workforce investment locally owned?
How much of the resulting business revenue remains within Hawaiʻi?
Does the model account for inflation over the ten-year period?
Does it distinguish genuinely new economic activity from spending that would have occurred without the intervention?
How sensitive is the $2 billion projection to the assumptions in the underlying earnings model?
What happens if workers sustain only part of the projected wage gain?
How would participant attrition or unemployment affect the economic-impact curve?
Does the model account for workers who leave Honolulu or Hawaiʻi after receiving support?
Could stronger earnings attract additional workers from the Neighbor Islands and deepen regional talent imbalances?
How much of the projected impact could appear as additional county or state tax revenue?
Would increased household demand generate new jobs beyond those directly supported?
Could additional spending intensify housing costs or other price pressures?
How much economic benefit would flow to landlords or companies headquartered outside Hawaiʻi?
Which investments in local food, energy, construction, and other supply chains could increase the multiplier?
Should workforce funding be directed toward industries with the strongest local purchasing patterns?
How should decision-makers compare Honolulu’s potentially higher returns with the greater need to build economic capacity elsewhere?
Could a statewide investment strategy use Honolulu’s growth to help finance or support Neighbor Island pathways?
What share of workforce funding should prioritize immediate economic return versus geographic equity?
What indicators would demonstrate that additional worker earnings are genuinely circulating within Honolulu?
How should decision-makers distinguish cumulative economic activity from fiscal return, social return, and direct benefits to workers?
