Models in Funding-additionality

// KEY VARIABLES

// Global climate funding by source
funding_uncertainty = 0.9 to 1.1
foundation_climate = 3.7B * funding_uncertainty
non_f_climate = (4.3B to 8.9B) * funding_uncertainty

/*
The relative size of a sector within climate (demand size) could be modeled lognormally
*/

// See here for data that informs choice of lognormal parameters: https://docs.google.com/spreadsheets/d/1Q1OuRNZhswqX2h5s5ovmfIuIcoyqC3YxeQlDqToN77w/edit?usp=sharing

p = 0.2
a = p * lognormal(-0.18, 0.6)
b = 0.3 * lognormal(-0.18, 0.6)
c = 0.3 * lognormal(-0.18, 0.6)

/*
Using general giving data to infer the home bias of individuals relative to foundations
*/

// Proportion of individual climate giving going abroad compared to foundation climate giving going abroad (odds ratio)
indiv_OR = 0.3 to 0.9

// Proportion of foundation climate giving going abroad
founda_intl = beta(10,5.15)
