Description

These four different functions provide estimates for the food consumption values in year t+1 given the consumption in year t, changes in income, and the elasticity of the particular commodity.

Usage

linear(food_t0, elas, gdp_pc_t0, gdp_pc_t1, pop_t0, pop_t1)

logLog(food_t0, elas, gdp_pc_t0, gdp_pc_t1, pop_t0, pop_t1)

semiLog(food_t0, elas, gdp_pc_t0, gdp_pc_t1, pop_t0, pop_t1)

logInverse(food_t0, elas, gdp_pc_t0, gdp_pc_t1, pop_t0, pop_t1)

Arguments

food_t0	The food consumption at time t.
elas	The elasticity of the commodity. This will vary by country and commodity.
gdp_pc_t0	Per person GDP (gross domestic product) at time t.
gdp_pc_t1	Per person GDP (gross domestic product) at time t+1.
pop_t0	Population at time t.
pop_t1	Population at time t+1.

Value

An estimate for the food consumption in year t1.
