What is the total local economic impact of sustained workforce investment on Kauaʻi when earnings gains recirculate through the local economy, compared with no intervention?
Workforce Understory Episode: Episode Four — Mobility Through Lifelong Learning
Geography: Kauaʻi County
Topic: STARs, upskilling, workforce investment, local economic impact, and regional infrastructure
The takeaway
This modeled scenario builds on the additional earnings generated by sustained workforce investment supporting Kauaʻi STAR workers into higher-wage roles.
Applying a 1.4 local economic multiplier, the model estimates that those earnings gains could generate approximately $165 million in additional cumulative economic activity by 2036.
The projected impact accelerates over time as workers supported in earlier years continue earning and spending more while new annual cohorts begin generating gains of their own.
Even within Kauaʻi’s small economy, sustained worker advancement could create meaningful benefits for local businesses and communities—provided enough of the additional income remains on-island.
What this visualization shows
This visualization compares cumulative economic activity on Kauaʻi 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 those earnings is spent and recirculated through Kauaʻi’s economy.
A multiplier of 1.4 assumes that each dollar of additional worker earnings produces approximately 40 cents in further economic activity beyond the initial income gain.
That additional activity could occur when workers spend more at local stores, restaurants, childcare providers, healthcare organizations, transportation businesses, service providers, and other island employers. Those businesses may then purchase additional supplies, expand employee hours, hire workers, or make further local expenditures.
The cumulative effect grows more quickly in later years because each new worker cohort adds to the earnings and spending associated with prior cohorts.
This is a prospective economic model rather than a record of observed impact.
Its results depend on the assumptions used in the underlying earnings model and on how much additional household spending remains within Kauaʻi. The projected total represents estimated cumulative economic activity, not public revenue, business profit, or a guaranteed return to the organizations funding the intervention.
Why this matters
The benefits of helping workers earn more can extend beyond the workers directly supported.
Additional income may allow households to spend more on essential needs, reduce financial instability, and purchase additional goods and services. When those purchases occur locally, the benefits can spread to businesses and workers across Kauaʻi.
In a small island economy, even a relatively modest increase in local spending could be meaningful.
A few million dollars circulating through locally owned businesses may support jobs, stabilize employers, and strengthen community services in ways that are visible across a small economic base.
But Kauaʻi may also experience substantial economic leakage.
The island imports much of what residents and businesses consume. Additional earnings may flow toward food, fuel, vehicles, construction materials, online purchases, housing costs, insurance, and other goods or services supplied or owned off-island.
If only a limited share of workers’ additional income remains on Kauaʻi, the realized economic multiplier could be lower than 1.4.
The industries employing upskilled workers will also shape the result. Wage gains connected to locally owned employers and local supply chains may produce more island-wide benefit than gains in sectors whose purchasing, ownership, and profits are concentrated elsewhere.
This means that workforce investment and local economic development cannot be separated.
Helping workers earn more creates the potential for wider economic impact. Increasing local procurement, strengthening island businesses, developing local supply chains, and expanding the availability of goods and services on Kauaʻi determine how much of that potential remains within the county.
This evidence invites Kauaʻi to ask:
How can the island increase worker earnings while also strengthening the local businesses and supply chains that allow those earnings to keep circulating on Kauaʻi?

Questions this visualization raises
What is the source of the 1.4 local economic multiplier?
Was the multiplier calculated specifically for Kauaʻi County?
How does Kauaʻi’s appropriate multiplier compare with those of Honolulu, Hawaiʻi, and Maui counties?
Does Kauaʻi’s reliance on imported goods and services make a 1.4 multiplier too high?
What share of each additional dollar earned is likely to be spent on-island?
How much spending leaks away through imported goods, online purchases, taxes, savings, and nonlocal ownership?
Which household purchases are most likely to remain within Kauaʻi’s economy?
Which purchases generate the greatest off-island leakage?
Do different industries produce different local multipliers?
Would wage gains in Construction, Healthcare, Hospitality, Utilities, or remote professional work circulate differently?
Are the employers receiving workforce investment locally owned?
How much of their revenue and profit remains on Kauaʻi?
Which employers purchase goods and services from other island businesses?
Could stronger local procurement increase the multiplier over time?
How much of the projected economic activity would flow toward housing?
Could increased earnings raise rents or other prices if supply remains constrained?
Does the model account for inflation?
Does it distinguish new economic activity from spending that would have occurred without the intervention?
