Key Concepts

Pure Competition

Pure competition is characterized by a large number of small firms that produce homogeneous products, meaning there is no product differentiation. Firms are price takers because the market determines the price, and there is free entry and exit in the market, ensuring no single firm can influence the overall market price. Additionally, perfect knowledge is assumed among both buyers and sellers, and the resulting equilibrium in this market is efficient in terms of resource allocation.

Pure Monopoly

A pure monopoly exists when a single firm is the sole provider of a product or service without any close substitutes, giving the firm significant market power to set prices. Such markets are usually maintained by high barriers to entry, which can be technological, regulatory, or due to exclusive control over a resource. The monopolist maximizes profits by controlling output and price, often leading to allocative inefficiency and a potential deadweight loss in the market.

Monopolistic Competition

Monopolistic competition features a market with many firms that sell products which are similar but differentiated through factors like branding, quality, or location. This differentiation grants firms some degree of market power and the ability to set prices above marginal cost, while still facing competition from alternative products. Although entry to the market is relatively easy, the differentiations lead to a non-price competition primarily through marketing and product innovation.

Oligopoly

An oligopoly is a market structure dominated by a small number of large firms, where each firm's actions can significantly impact the market. Products may be either homogeneous or differentiated, and firms tend to be interdependent, meaning the strategic decisions of one firm affect the others. Barriers to entry are typically high, which helps maintain the market power of the existing firms. This interdependence often leads to complex competitive behaviors such as collusion, strategic pricing, and non-price competition.

00:01 Here we are looking at the different types of markets in economics and their characteristics.

00:07 And then we're looking at some examples to see which one lines up with which market.

00:11 So starting off with perfect competition, the characteristics include a large number of firms, and these firms are producing the same exact product.

00:20 And these firms are going to be price takers, and there are no barriers of entry.

00:25 So think of this as typically farms.

00:28 They're all producing the same product, and they have no control over the price.

00:31 Of that product, it's dictated by the market demand.

00:35 Now, monopoly is the complete opposite of perfect competition.

00:39 While there was a large number of firms, now there's only one firm.

00:42 Instead of the same product, we only have one unique product for monopoly, and there's a large amount of price control, and the entry is blocked.

00:50 So the monopoly, only one firm is in the market.

00:53 That's the biggest characteristic to remember.

00:55 Because it's by itself, it has a lot more price control.

00:58 Now, kind of aggregating these two, in between, perfect and monopoly you would find monopolistic so these are the two extremes and now we're looking at the two in the middle monopolistic is a combination where there are many firms with slightly differentiated products and there may be some price control and there are some slight barriers of entry for this i typically think of toothbrushes and sort of these small house appliances that don't matter too much but this would be an example of monopolistic and and lastly, we have the oligopoly.

01:33 Now, monopolistic is more like perfect, but not exactly perfect.

01:36 Oligopoly is more like monopoly, but not a perfect monopoly.

01:40 So this is because there are a few firms, not just one firm.

01:44 And this can have either the same or slightly differentiated products.

01:48 And the prices are interdependent.

01:49 Now, this means they depend on each other.

01:51 The firms are going to essentially play games with each other to think about prices and strategize in that sense.

01:57 Interdependent means that they're reliant on each other.

01:59 And there are many barriers of entry.

02:02 It's not impossible, but there are many barriers.

02:04 So now, looking at these characteristics, we're going to try matching up with these examples.

02:09 So starting off with the hometown supermarket, this can be argued many ways, but i would tend to think of this as an oligopoly.

02:17 So let's draw it so we can remember.

02:20 So this can be an oligopoly and maybe even a monopoly if the town is small and there's only one grocery store.

02:26 But when you think about it, there are other hometown supermarket.

02:30 That are kind of competing with each other, they have pretty similar products, and the prices are dependent on each other...
