MBA Week 0 — Quant Microecon Bootcamp

An MBA Week-Zero quantitative microeconomics bootcamp. Across three 25-minute rounds anchored on Café del Valle (a 40-store specialty-coffee chain in Costaria), participants read own-price elasticity off real POS data, apply the Lerner condition to find the elasticity-optimal price, decompose the welfare cost of a sin tax (CS loss, PS loss, government revenue, deadweight-loss triangle, Harberger t² scaling), and solve a Cobb-Douglas Lagrangian for two-good consumer choice — recovering the equimarginal principle and the marginal utility of income.
