$($a$)$ Consider a rice farmer planting two $(2)$ types of rice, white and brown rice, concurrently

in his rice field using the same resources and technology and harvesting them at the

same time. Given that consumers like to mix both white and brown rice in their daily

consumption, explain the effect on the white rice market when the price of brown rice

increases. Support your answers with suitable white rice market diagrams.

$($b$)$ Consider a farmer that produces both white and brown rice. It is discovered that the

demand for brown rice is relatively more inelastic compared to the demand for white

rice. Initially the price of both white and brown rice is the same and the farmer produces

the same quantity of white and brown rice. Now there is an improvement in agricultural

technologies that affect both white and brown rice equally. Employ the demand and

supply model to compare and contrast the effects on the equilibrium price and quantity

of both white and brown rice from the technological improvement. Explain the effects

on the farmer$$s revenue from both types of rice after the change in technology and

support your answers with one suitable market diagram. In addition, discuss the

situation where the improvement in technology may be detrimental to the producers.

$($c$)$ It is discovered that the consumption of white rice is linked to many cases of diabetes.

To discourage the consumption of white rice, the government is contemplating two $(2)$

policies, an effective price floor on white rice and a tax imposed on the producers of

white rice. Appraise the efficiency of the two $(2)$ policies and compare and contrast

their welfare effects, assuming that both policies resulted in the same price and quantity

of white rice in the market. Support your answer with a suitable white rice market
