Answers
1.a. The law of supply explains that a seller is willing to increase the quantity supplied when the price increases, as it leads to higher potential profits. [1 mark]b. If the wholesale price of mangoes increases, the vendor's cost of production rises. According to the law of supply, a higher price generally incentivizes producers to increase output, but if the wholesale price (cost to the vendor) rises sharply, his profit margin might shrink or even disappear at the previous selling price. He would likely be willing to supply less at the old selling price, or he would need to raise his selling price to maintain the same or higher quantity supplied. If we assume demand is constant and he still sells at the original price, he will supply less. If he raises his price, the quantity supplied might increase relative to what he would supply at a lower price. Assuming the question implies a rise in selling price due to increased costs, he would likely supply more if the new selling price is profitable. However, if the question implies that the increased wholesale price reduces profitability at the current selling price, he would supply less. Given the context of increasing his selling price, it implies he wants to maintain profitability. So, if the selling price is increased to compensate for the higher wholesale price, he would be willing to supply more, following the law of supply. If we interpret the question as "despite the increased wholesale price, how much is he willing to supply at some selling price?", then the law of supply suggests he'd supply more at higher prices. Let's assume the question implies the law of supply applies to his selling price, which he adjusts. Thus, he would be willing to supply more if he can charge a higher price. [2 marks]c. This illustrates the Law of Demand, which states that as the price of a product falls, the quantity demanded increases, and vice versa, assuming other factors remain constant. It implies an inverse relationship between price and quantity demanded. 2marks

a. A price ceiling is a government-imposed maximum price that can be charged for a good or service. [1 mark]
b. If the price ceiling is set below the market equilibrium price for essential medicines, it will likely lead to a shortage. The quantity demanded will exceed the quantity supplied because the medicine will be cheaper, but manufacturers may be unwilling or unable to produce enough at the lower mandated price. [2 marks]
c. The government may intervene to ensure that essential goods like medicines are accessible to all citizens, regardless of their income, promoting equity and public welfare. Markets may not always provide goods at prices that are affordable for everyone, especially vulnerable populations. [2 marks]
4.a. Two other factors influencing demand for the new smartphone are:
1Tastes and preferences (e.g., brand loyalty, desire for the latest technology).
2Future price expectations (if consumers expect prices to fall after the initial launch rush).
3Price of substitute goods (e.g., competing smartphone models). 2marksb. If consumers expect prices to rise in the next quarter, they may postpone their purchases to take advantage of current prices or expected future discounts. However, if they expect prices to rise significantly due to shortages, they might be motivated to buy now to avoid higher prices later. The question states "further price increase", implying consumers might anticipate this and increase their current demand to buy before prices go up even more. [2 marks]

a. The farmer's decision is influenced by the profitability of alternative crops. Since chickpea cultivation is more attractive due to subsidies and potentially higher market prices, he might consider it a better option than wheat, which has low prices. This relates to the concept of 'price of related goods' (in this case, potential substitute crops) influencing supply decisions. [2 marks]
b. If many farmers switch from wheat to chickpeas, the number of sellers in the wheat market will decrease. This will lead to a decrease in the overall market supply of wheat, shifting the supply curve to the left. [2 marks]

a. The economic principle driving the organizers to increase the price is the market mechanism for handling excess demand. By increasing the price, they aim to bring the quantity demanded closer to the quantity supplied, reaching a new equilibrium or at least reducing the demand to a manageable level. [1 mark]
b. An increase in the ticket price would likely lead to a decrease in the quantity of tickets demanded (as fewer people are willing or able to pay the higher price) and an increase in the quantity of tickets supplied (if more tickets were available and willing sellers could be found at that higher price, though in this case, supply is fixed by venue capacity, but the higher price would incentivize selling all available tickets).

a. The hailstorm damaging the onion crop will lead to a decrease in the supply of onions in the market. The supply curve will shift to the left. [1 mark]
b. With a decrease in supply and assuming demand remains constant, the market price of onions will increase, and the equilibrium quantity sold will decrease. This is because there will be excess demand at the original price, leading to upward pressure on prices. [2 marks]

a. Imposing a tax on sugary drinks will increase the cost of production for manufacturers (if taxes are levied at production) or increase the final price for consumers. This would likely lead to a decrease in the quantity supplied (as producers might find it less profitable) and a significant decrease in the quantity demanded (as consumers will find them more expensive). [2 marks]
