File Descriptions

Bioeconomic_Simulation_Code.jl is the code used for all the bioeconomic model simulations in the paper. Note these simulations take around 55 hours to run.

Bioeconomic_Model_Main_Results.do is the code used to create the main results figures: Figures 1, 3, 4, S1, S2, and S3. These figures are the result of stochasitic draws and numerical simulations in Bioeconomic_Simulation_Code.jl. Each run of the code might result in slight differences in the final figures.

Fertilizer_Infection_Results.do is the code used to create Figure 2.

Disease_Ecology_Simulation.jl simulates the disease ecology model used in the main simulations. This code creates Figure S4.

Household_Survey_Summary_Statistics.do is the code used to calculated household summary statistics used to calibrate the bioeconomic model. This code creates Tables S1 and S2.

Expenditure_Shares.do is the code used to estimate the expenditure shares used to calibrate the bioeconomic model. This code creates Table S3.

Factor_Cost_Shares.do is the code used to estimate the expenditure shares used to calibrate the bioeconmic model. This code creates Table S4.

Vegetation_Production_Function.do is the code used to estimate the vegetation production function. This code creates Table S8.

Back_of_the_Envelope_Calculations.do is the code used for the back of the envelope calculations for the broader income benefits of aquatic vegetation removal.

All .csv files are produced by Bioecnomic_Simualtion_Code.jl and are used by Bioeconomic_Model_Main_Results.do and Fertilizer_Infection_Results.do to create the core results. Each .csv file has a corresponding codebook that describes the data in the file.

Computing Environment and Packages

All code was created in Julia 1.6.2 and Stata 16.

The Julia code uses the following packages: NLopt, Plots, LinearAlgebra, Distributions, Random, DifferentialEquations, DelimitedFiles

The Stata code uses the following packages: blindschemes, cleanplots, palettes, schemepack, grc1le, estout

Replication Instructions

Step 1: Download the necessary data from the World Bank and Zenodo.

Step 2: Put all data and code in a folder titled "BioeconomicModelResults". All directories should start from where you find the "BioeconomicModelResults" folder.

Step 3: Run the file Bieconomic_Simulation_Code.jl. This file produces the simulation results for the paper. It outputs the .csv files in this repository which can be used to directly replicate the paper's figures.

Step 4: Run the main results figure file, Bioeconomic_Model_Main_Results.do.

Step 5. Run the additional .do files and .jl files to replicate the additional figures and tables.
