Test on Market Equilibrium and Price Transmission

Question 1: Is Free State identified as a surplus-producing region for maize?

A. Ano

B. Ne

Explanation: The study materials state that Free State is a surplus-producing region.

Question 2: Given the provided demand and supply conditions, trade of maize will occur between Free State and Durban when a transportation cost of R5 per unit is introduced.

A. Ano

B. Ne

Explanation: Trade occurs when the price difference between the exporting and importing region is greater than the transportation cost. In this scenario, Free State, the surplus region, has a supply value of '05.00.00', while Durban, the deficit region, has a demand value of '04.00.00'. As the supply value from the surplus region is greater than the demand value in the deficit region, and the transportation cost of R5 per unit would further widen any potential gap, trade will not occur under these conditions.

Question 3: Based on the provided study materials for Market A (Free State) where Demand is '04.00.00' and Supply is '05.00.00', and for Market B (Durban) where Demand is '04.00.00' and Supply is '05.00.00', what can be concluded about the equilibrium price and quantity for each market?

A. For Market A, equilibrium quantity is 4 units and equilibrium price is 5. For Market B, equilibrium quantity is 4 units and equilibrium price is 5.

B. For Market A, there is a surplus of 1 unit. For Market B, there is a surplus of 1 unit. Without price functions, equilibrium cannot be determined.

C. For Market A, equilibrium quantity is 5 units and equilibrium price is 4. For Market B, equilibrium quantity is 5 units and equilibrium price is 4.

D. The equilibrium price and quantity cannot be calculated for either market with the given information, as specific demand and supply functions or a common price point are not provided.

Explanation: The study material provides discrete values for 'Demand' and 'Supply' (e.g., '04.00.00' and '05.00.00') for each market, but it does not provide demand and supply functions (e.g., equations relating price and quantity) or a common price at which these quantities are observed. Therefore, it is impossible to calculate a specific equilibrium price and quantity using only the numbers given in the format '04.00.00' and '05.00.00' without further information on how price influences these quantities.

Question 4: Based on the provided study materials, which market is identified as having deficit maize production?

A. Market A: Free State

B. Market B: Durban

C. Both Market A and Market B

D. Neither Market A nor Market B

Explanation: The study materials explicitly state, 'Free State (a surplus-producing region) and Durban (a deficit-consuming region)'. This identifies Durban as the region with deficit production.

Question 5: An increase in global wheat prices can cause an increase in local bread prices in South Africa.

A. Ano

B. Ne

Explanation: Due to the Russian and Ukrainian war, the global prices of wheat increased, which led to the prices of bread in South Africa increasing. This demonstrates the transmission of international commodity prices to local prices of goods made from them.
