Rational_choice_model

# Rational choice model ## MicroSim spec - **Recommended sim type:** game-theory payoff grid - **Microsimmability score:** 60/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Payoff spread` - `Risk weight` - `Option count` ### What animates An agent ranks options by expected payoff and selects the maximizing choice as values change. ### Learning objective Show how an agent maximizing expected payoff selects among options. ## Links (Wikipedia order)  `Agricultural_economics` · `Alex_Abella` ·

model assumes agents select actions that maximize their expected payoff given their preferences and constraints. ## Build checklist - [ ] Claim it: set `status: in-progress` + `lease` + `leased_at` - [ ] Write the child page explaining the concept (tie it back to systems science) - [ ] Finalize parameter ranges and defaults - [ ] Implement the p5.js sketch (drawing + control regions) - [ ] Add caption + the learning objective on the page - [ ] Set `status: done` ## p5.js sketch ```javascript // MicroSim: Rational choice model let controls = {}; function setup() { // createCanvas(...); create sliders for the parameters above. } function draw() { // background(...); read controls; render game-theory payoff grid; respond live. } ``` --- Back to Systems Science · Wikipedia: [Rational
