Episode Details

On today's behavioral economics foundations episode we are going to be talking about the network effect (or perhaps it is more accurate to say "networking effects" because as you will learn throughout the episode, there are multiple kinds and situations for how they can be useful in a business). I am also going to talk about some pitfalls to look out for and how to incorporate behavioral economics into all of that.

This episode is related to the topic from last week about subscription models and even more directly to membership groups. I will explain that specifically throughout the episode, and if you haven't listened to that one yet you will want to check it out. It's episode 105 and there is a link for you in the show notes. Today, I'll tell you what the network effect is and how it works, what it is not, some pitfalls to look out for, behavioral economics concepts to keep in mind, and so much more.

And before we jump right into the network effect, a quick shout out to Clayton Key, whom you can all thank for today's episode. Clayton and I connected on LinkedIn and in our messenger conversation he recommended the topic of this episode. Do you have a topic or question you'd like to suggest for an upcoming episode?

• [08:18] A direct network effect is when an increase in usage and users leads to a direct increase in the product or service's value for other users.
• [08:59] When you get to a platform business they are a little more complex because there are multiple user groups to consider, which is when you get to a two-sided network effect.
• [10:37] The key difference from a two-sided network effect and a direct network is that the type of user joining matters.
• [12:19] In the case of a social network, which is a two-sided network as well, they need to be monitoring their user quality to remain viable and increase value.
• [13:47] To attract the advertisers and make money, you need good users.
• [15:14] As each local network grows and increases engagement, the value of the entire network grows along with it.
• [16:50] People can of course be a part of many groups, and so attracting diverse users who understand all the content they can get access to on the platform is key.
• [18:19] Network externality is an economics term that is showing how demand increases when other people buy a product.
• [19:36] A business can have network effects but not be "viral".
• [21:18] If you are looking to start on a network effect business, you need to understand when you will hit critical mass, what it looks like when you get there, and what you need to do to get there quickly so you can move into that value point.
