Railsback and V. Grimm for Chapter 10 of the book Agent-Based and Individual-Based Modeling, 2nd edition (2019).</p> <p>This is the first version of the model, as described in Section 10.4.1.</p> <h2 id="overview">OVERVIEW</h2> <h3 id="purpose-and-patterns">PURPOSE AND PATTERNS</h3> <p>The primary purpose of this model is to explore the effects of sensing&mdash;what information agents have and how they obtain it&mdash;on emergent outcomes of a model in which agents make adaptive decisions using sensed information. The model uses investment decisions as an example, but it is not intended to represent any real investment approach or business sector. (In fact, you will see by the end of chapter 12 that models like this one that are designed mainly to explore the system-level effects of sensing and other concepts can produce very different results depending on exactly how those concepts are implemented. What can we learn from such models if their results depend on what seem like details? In part III of this course we will learn to solve this problem by tying models more closely to real systems.)</p> https://www.ees4760.jmgilligan.org/projects/telemarketer_odd/ Thu, 22 Aug 2019 00:00:00 +0000 https://www.ees4760.jmgilligan.org/projects/telemarketer_odd/ <h1 id="the-telemarketer-model">THE TELEMARKETER MODEL</h1> <p>This model was produced by S. Railsback and V. Grimm for the book: <em>Agent-based and Individual-Based Modeling: A Practical Introduction</em>, 2nd edition (2019).</p> <p>This version is the first, basic version of the model as described in Section 13.3.1.</p> <p>Let us visit the formerly remote land of Wasellya, which has developed very rapidly, so suddenly all its citizens have telephones. Naturally, the &ldquo;invasion&rdquo; of telephone technology is followed rapidly by an invasion of people tempted to start a telemarketing business. Is this a good business risk? How many telemarketers will stay in business, for how long? How does the average life span of a telemarketing company depend on how many are started? Here is the ODD description of a simple model for this problem; you should implement the model.</p>
