ECONOMIES OF SCALE
Scale—it’s not just the thing covering a lizard’s skin 🐊. It’s also a way to measure efficiency in production. And if you’ve ever wondered why bigger companies sometimes dominate 💪 you’re thinking about economies of scale.
What Are Economies of Scale?
Economies of scale happen when a business gets bigger and its average costs (the cost of making one unit of a product) go smaller. It’s like ordering a family-size pizza 🍕—more food for less cost per slice!
This happens because as you scale up, you can spread your costs over more units, negotiate better deals, and streamline operations. Think of it as the business world’s ultimate power-up.
Imagine you’re running a lemonade stand:
* If you sell 10 cups, you still have to pay for the juicer, lemons 🍋 and sugar.
* If you sell 1,000 cups, the cost of the juicer gets divided across way more cups, making each one cheaper to produce. The average cost of each cup continues to fall! 📉
This is the absolute genius of economies of scale!
Why Bigger Means Cheaper
Bulk Buying: Big businesses buy in bulk, which means suppliers give them discounts. If you’re running a 🍜 ramen shop 🏬 you might pay $5 per bag of noodles. But if you’re a massive chain like Ichiran, you can negotiate to pay $3 per bag because you're buying thousands of bags at a time - which is better for the noodle factory because they'd rather you order a million units than ten.
Better Deals on Capital: In a similar sense, larger businesses often get financial economies of scale 💵—banks are happy to lend to them at lower interest rates because they’re bigger loans! 💵 💵 💵 💵 💵
Let’s say you’re a small bakery asking for a $10,000 loan. Banks might charge you 10% interest because they see you as small potatoes. Now imagine you’re a multinational bakery chain borrowing $10 million. Banks might charge only 1% interest because they want your business.
10% of 10,000 = $1,000
1% of 10,000,000 = $100,000
If you were a bank which would you prefer?
Or, as the saying goes:
If you owe the bank $10,000, you have a problem. If you owe the bank $10 million, the bank has a problem. But it's a good problem.
Operational Efficiency: Imagine you run a small boutique 🥐 bakery. You might only have a single oven 🎛️ and it’s working overtime. But a larger bakery can afford giant industrial ovens 🎛️🎛️🎛️🎛️ that churn out hundreds of loaves per hour, lowering the cost of each loaf. 🥖🥖🥖🥖🥖
The Catch: Diseconomies of Scale
But…bigger isn’t always better. This is called diseconomies of scale—when being too big causes costs to rise instead of fall.
Coordination becomes harder as operations grow more complex, communication slows down with too many layers of management, and employees may duplicate efforts or lose accountability. At a certain size, the inefficiencies outweigh the benefits of being bigger. Too many cooks in the kitchen.

Conclusion
Economies of scale are part of why businesses aim to grow—it makes them more efficient, lowers costs, and gives them a competitive edge. It's a key concept economics students must understand while studying theory of the firm / market structures.

Fun Fact: the quantity (Q*) where all economies of scale are captured, where average cost is at it's minimum is also called minimum efficient scale and is productively efficient.
