Beauty and complexity of nature

In this video Wander Jager explains that the difference between more traditional local fisheries and the large fishing operations on the open ocean may be considerable. Especially the connection with …

Satisficing versus maximising

In the previous experiments we programmed the fishermen so that they not only want to catch a lot of fish, but that they also want to be home. This seems …

How many fish are there?

The exact sizes of different fish stocks are unknown, as we can’t get perfect data on how many fish there are. Fish are often migrating, and make part of a …

Social simulations

What you’ve been doing in the previous exercise was experimenting with a social simulation model. In such social simulations we can create many different types of agents – here fishers …

Let’s go fishing!

Last week we discussed renewable resources, such as grass that cows eat to produce milk, and fish populations that have a capacity to regrow. In scientific research we call this …

Common knowledge

In the previous step we asked what would happen if Anna and Ben had inaccurate beliefs about each other’s knowledge. We analysed the situation presented in the table below. We …

Managing a common kitchen

Now we will look if Ben, Anna and Celeste will use any of Ostrom’s suggestions in their dirty kitchen. How do you think we could apply some of Elinor Ostrom’s …

The Tragedy of the Commons

In the video below you will see the most classical example of a Multi-Person Prisoner’s Dilemma that relates specifically to common resources. It is called the Tragedy of the Commons. …

Governing the Commons (with success)

In this step we will present the main results of Ostrom’s research about managing Common-Pool Resources and by that we will start investigating how best to design solutions to the …

Managing common pool resources

Let’s think again about public transportation. When you are afraid of the ticket inspector, it means that you are afraid of the sanction. When you think that it is unfair …

The future of socio-ecological models

Until now you have learned about how people can share collective goods, and how computational models can contribute to understanding the social dynamics in such situations. As humanity we face …

Caring about the local community

In this video the fisherman Dirk Sloot tells about how much people care about each other in the local community. This clearly demonstrates that people are not selfish outcome maximisers, …

Choosing the right internet offer

In this article we will explore further how multi-person situations with either-or choices can be represented on a chart. We’ll consider situations where there are only two options to choose …

How to analyse multi-person games?

Before we explore the problems with shared resources further, we will see how we can analyse different situations where there are many people who face the same choice between two …
