How A Single Costco Changes Its Local Economy

Overview: From the “Walmart effect” to the “Costco effect”

The summary frames Costco’s impact on local economies as a reversal of the widely discussed “Walmart effect.”

• Big-box retailers like Walmart are described as:
  • suppressing wages,
  • pushing nearby small businesses out,
  • and reducing local pay due to pricing power and competition.
• Costco, in contrast, is argued to generate the opposite outcomes in documented cases:
  • higher wages,
  • more local business activity,
  • and rising local prices without eliminating buyer power.

Key example: a high-performing Costco near Honolulu

• Costco has 914 locations worldwide across 14 countries, and typically places stores in major metropolitan areas in North America.
• The video claims the busiest location is not where many would expect—citing a store near Honolulu, Hawaii.
  • It reportedly generated close to half a billion dollars in sales in the last fiscal year (based on estimates from public financials).
• This store is used to illustrate how a single retail hub can function like a major local employer (similar scale influence to factories or mines).

Walmart effect vs. Costco effect

The “Walmart effect” (as described)

• Increased closures of nearby businesses on surrounding blocks
• Wage suppression
• Harm to local economic conditions because Walmart becomes the dominant employer and price setter

The “Costco effect” (as argued)

• Costco is still acknowledged as a large, low-price, membership retailer.
• However, the video argues its effects are “almost exactly the opposite” in documented cases.

Japan case study: GMA Prefecture near Tokyo

• In 2023, Costco opened its 851st location in GMA Prefecture, about an hour outside Tokyo.
• The area is characterized by suppressed wages and thin-margin local businesses.
• The video describes Costco building a large superstore on what was previously rice fields, then producing two major effects:

1) Wages rise (instead of falling)

• Costco allegedly pays entry-level staff about $10/hour (equivalent), versus roughly $6.50/hour locally.
• Local businesses reportedly increased wages by about 40% within three months to retain workers.

2) Local business revenues increase (instead of collapsing)

• Unlike Walmart, Costco is described as becoming a destination rather than merely a convenience stop.
• Costco shoppers reportedly:
  • may visit less frequently than Walmart shoppers, but
  • spend more when they do.
• Because Costco requires membership, many customers also shop elsewhere for everyday needs—boosting foot traffic and sales spillovers.

Why the “magnet” dynamic matters

• For a less-developed area like GMA, Costco draws shoppers from farther away.
• Those trips can spill into other local spending (e.g., dining out).
• The video claims the pattern holds globally: Costco tends to raise the local wage floor while still expanding demand enough to benefit nearby businesses.

“Unintuitive” price increases that may still help locals

In lower-income areas, the video argues Costco can allow local businesses to raise prices—yet still improve local conditions because:

• People have more money from higher wages.
• Consumers continue to rely on local businesses for niche or more unique goods.
• Essentials shift toward Costco (reducing pressure on locals for “budget” pricing), while locals sell higher-margin items.

Net result: prices may rise, but locals may be better off due to wage gains and demand reallocation.

How Costco achieves these outcomes (economic logic, not goodwill)

The video argues Costco’s benefits are not charity; they align with shareholder value.

• Costco’s ethics code is cited/contrasted (obey law; care for members, employees, and suppliers), and the summary suggests these commitments ultimately support shareholder rewards.
• Higher wages are described as strategic choices that:
  • improve brand perception and membership renewals,
  • reduce staff turnover,
  • and lower hiring/training costs.
• The video claims Costco turnover is far lower than industry norms (60% vs. 5.5%), emphasizing operational efficiency and retention.

Why other retailers don’t copy Costco

• A Harvard Business Review report is cited: wage strategy works only for certain business models.
• Costco is portrayed as more stable than retailers that frequently reconfigure store footprints:
  • it rarely shuts stores once established,
  • unlike Walmart’s frequent closures.
• Career progression differs:
  • Walmart’s larger store network creates more management roles and faster upward mobility,
  • while Costco has fewer positions—so Costco must retain staff by making current jobs better.

Costco’s relationship with local businesses

• Costco is described as relying on local suppliers/restockers rather than competing directly against them.
• The video emphasizes Costco’s “wholesale-meets-retail” model, helping smaller hospitality businesses buy in bulk without dealing directly with suppliers.
• It also addresses a misconception about variety:
  • Costco is said to stock far fewer distinct items than Walmart or Amazon (roughly 4,000 “stocking units” vs. 100,000+ at Walmart and hundreds of millions at Amazon).
  • Fewer SKUs supposedly create niches where local businesses can buy Costco goods and resell them differently.

Evidence from research and the Hawaii logistics angle

• A 2019 study (University of Massachusetts; related framing with NBER) is cited:
  • after a Costco opened, local business prices rose.
• The explanation given:
  • Costco-driven demand plus higher wages increased the local ability to sell higher-margin products,
  • while essentials were increasingly handled through Costco’s demand patterns.
• Hawaii is used to reinforce Costco’s logistical role:
  • bulk shipping into the Pacific makes Costco a “lynch pin” for both consumers and small businesses,
  • reducing the burden and cost of individual shipping.

Closing contrast with Walmart

The video concludes by asserting that Costco is powerful but not as dominant as Walmart, and it hints at a follow-up on how Walmart succeeded by doing things differently.
