EnvironmentalEconomics — Academic Booklet Repository

This repository is an academic booklet collection for core methods in Environmental Economics: Cost–Benefit Analysis under Risk, Valuation of Ecosystem Services, Revealed Preference Methods (Hedonic Pricing, Travel Cost), and Biodiversity Valuation / Conservation Portfolio Choice (Noah’s Ark, Weitzman diversity).

Each booklet folder contains:

• A PDF “booklet” (problem + worked solution / lecture note)
• A fully runnable code file (R)
• A short, professional README describing the method, assumptions, and outputs

How to run the code

All scripts are self-contained.

1. Install R (≥ 4.2 recommended).
2. Install required packages (most scripts use tidyverse + ggplot2):

   install.packages(c("dplyr","tidyr","purrr","ggplot2","scales","MASS"))
