Modeling a Dynamic Trade War using Julia: Assumptions, Simulation, and Impacts on the US Economy

Modeling a Dynamic Trade War using Julia: Assumptions, Simulation, and Impacts on the US Economy

Building a simple dynamic simulation in Julia


This article explains a simplified simulation using game theory (the prisoner's dilemma) to analyze the impacts of imposing tariffs between the US and its major trading partners, highlighting potential short-term economic benefits such as increased revenues and domestic protection. The examples are coded in Julia and the files are available on github. https://github.com/etorkia/SharedDecisionModels/tree/main/PrisonnerGame

Bayesian Reasoning using R (Part 2) : Discrete Inference with Sequential Data

How I Learned to Think of Business as a Scientific Experiment

Imagine playing a game in which someone asks you to infer the number of sides of a polyhedron die based on the face numbers that show up in repeated throws of the die. The only information you are given beforehand is that the actual die will be selected from a set of seven die having these number of faces: (4, 6, 8, 10, 12, 15, 18). Assuming you can trust the person who reports the outcome on each throw, after how many rolls of the die wil you be willing to specify which die was chosen?
