### SMS Essay Competition 2019

**“Mathematics and Economics”**

- Economics has long been a crucial part of our daily life, as it is the study of the production, consumption and transfer of goods and wealth. Why is there inflation? Why does the petrol price fluctuate frequently? Why do certain stocks rise while others plummet? To model, explain and predict the behaviors behind these activities, economists turn to Mathematics and obtain an astonishing success.
- The main objectives of this year’s competition are to introduce the students to the different branches of economics, such as microeconomics, macroeconomics, game theory and finance, and to let the students understand how mathematics is applied in them.
- We also hope that through this competition, students will be exposed to a variety of different mathematics topics such as calculus, differential equations, functional analysis, convex sets, optimization, graph theory, dynamic analysis, Monte Carlo method, Brownian motion, stochastic calculus, probability, statistics, modeling, etc.
