hello everyone so in this unit we're
gonna try to take everything we've
learned about netlogo and agent-based
modeling and agents and we're gonna try
to put it together to create our first
model from scratch from the ground up
right and I'm gonna be giving you a lot
of code and explanations along the way
but hopefully leading you through the
hand its leading you by the hand so you
can see how this all works together and
then this start with some inspiration
you know and then 1996 Josh Epstein
arrived Extell published won the first
definitive books on agent-based modeling
is social science called growing
artificial societies which was populated
by artificial economic agents and others
through their basic model which was
sometimes referred to a sugar scape
right was really kind of had these
agents in them that interacting economic
ways right and that was one of the first
examples and that really inspired a lot
of work into using agent-based modeling
to explore how economies work in how
societies work so we're going to create
a simple model of economic agents
inspired in part by experts in acts
those work and the paper by draging
Lascaux and yoko Benko in 2000 and the
basic idea is the following right we're
gonna create a 500 agents that start off
$100 each and every tick each person
gives one down there to another person
randomly the idea is that this somehow
models the exchange economy right did I
give you a dollar for an apple you might
give me a dollar for my teaching right
whatever right and if you run out of
money at the end you can't give any more
money until someone gives you money you
can't give me more money away so you
can't buy anything if you have no money
it's the basic idea so given the fact
that we start with this uniform
distribution the question that
journalists doing activate go in others
fast right is what will the final
distribution of wealth be in this very
very simple economy right so we're gonna
explore that in the next couple of
slides
