1. Consider an economy which produces and sells, among a host of other things, orange
juice. The average glass of orange juice begins life when a farmer harvests oranges,
then sells them to a juicer for $3.00, and the juicer sells the juice to a wholesaler for
$4.50, which sells the juice to a retailer for $5, who sells it to you for $6.75. The farmer
paid an assistant $1.50 for every glass worth of oranges sold to the juicer. The juicer
paid its employees $0.75 for each glass worth sold to the wholesaler. The wholesaler
paid its workers $0.10 for every glass worth sold to the retailer. The retailer paid its
employees $1 for every glass sold to you. Answer the following:
(a) How much does your purchase of a glass of orange juice add to GDP, as measured
by overall spending?
(b) What is the value added to each glass by the farmer?
(c) What is the value added to each glass by the juicer?
(d) What is the value added to each glass by the wholesaler?
(e) What is the value added to each glass by the retailer?
(f) What is total value added for each glass of orange juice?
(g) How much income do workers in this economy earn for each glass of orange juice?
(h) How much profit do capitalists in this economy earn for each glass of orange juice?
(i) What is the labor share in this economy?
(j) What is total income earned for each glass of orange juice?
(k) What can you say about your answers to Parts (a), (f), and (j)?
