Imagine being the only pizza place in a small town; you're what we call a monopoly. Monopoly firms, or those with significant dominance in their markets, have significant market power. They're like the 'big boss' of their marketplace, with no competition to worry about. Now, this may sound cool if you're the boss, but from society's perspective, it's usually not so good.

Real-World Example: Think about Microsoft in the early days of personal computing. They had a significant monopoly power, dominating the market, and dictated the price and availability of their products.

The Downside of Monopoly Firms

Why is this not desirable? For starters, monopoly firms can restrict output, meaning they control how much of a product is available. It's like our pizza place deciding to make only 10 pizzas a day. Less availability can lead to consumers enjoying less of the product.

Real-World Example: If DeBeers, a company that controls most of the world's diamond mines, decided to only release a limited number of diamonds each year, diamond lovers (and proposers) will have a hard time!

Monopolies can also charge higher prices due to this restricted output. This hits consumers' wallets hard, especially lower-income households, as it reduces their purchasing power. Imagine if the only pizza place in town started charging $50 for a pizza! This leads to a shrink in consumer surplus (the extra satisfaction or utility that consumers enjoy when paying less than what they are ready to pay) and transfers it to the monopoly firm, thus increasing income inequality.
