Assume the following log-linear supply function for coffee beans:

ln Qs = 20 + 1.5 ln P +4.6 Ln T + 2.6 ln F where P is the price of coffee beans, T is technology and F is the number of coffee bean growers. If the number of growers increases by 10%, by how much will coffee supply increase?

Answer #1

We know

d lnQs/d ln F=2.6

which means an increase in F by 1% will lead to an increase in quantity supply by 2.6%

Thus coffee supply will increase by 26% when Number of coffee bean grower increases by 10%

ans is 26%
