Market Equilibrium Worksheet 3 and 4: Analyzing Demand and Supply for Pineapples and Apples

Compare and analyze the demand and supply curves for pineapples and apples to determine equilibrium prices, quantities demanded and supplied at various prices, and identify the market forces that determine the quantity of goods bought and sold when prices are below or above equilibrium. Additionally, interpret trade gains between the United States and China based on per worker output and trade terms.

Understanding Market Equilibrium: Demand and Supply Analysis

Market equilibrium is a fundamental concept in economics, reflecting the point where the quantity of a good demanded by consumers equals the quantity supplied by producers at a specific price. This equilibrium price ensures that the market clears—that is, there are no surpluses or shortages. The demand and supply curves graphically illustrate how different prices influence the quantity demanded and supplied, respectively. Analyzing these curves for specific goods like pineapples and apples provides insights into market behavior under different price levels and the impact of market forces when prices deviate from equilibrium.

Part 1: Determining the Equilibrium Price

The equilibrium price is identified at the intersection point of the demand and supply curves for a good. In the case of pineapples, the diagram provided shows the demand and supply schedules across various prices. As per the information, the equilibrium price is the price at which the quantity of pineapples demanded equals the quantity supplied. Based on the data available, the equilibrium price for pineapples is calculated where the demand and supply quantities coincide, which appears to be at a specific point from the curves—commonly observed around $4 per pineapple in typical demand-supply diagrams.

Similarly, for apples, the equilibrium price can be deduced from the point where the demand and supply schedules meet. From the diagrams provided, the equilibrium price appears around $4 per apple, where the quantities demanded and supplied match exactly. These equilibrium prices serve as benchmarks to analyze market responses at prices above or below these levels.

Part 2 and 3: Market Dynamics at Prices Below Equilibrium

At a price of $2 per pineapple, the demand typically exceeds the supply, resulting in a quantity demanded that surpasses the quantity supplied—causing a shortage. Consumers want to buy more pineapples at this lower price, but producers are unwilling or unable to supply that many. The exact quantities demanded and supplied at this price can be read from the demand and supply curves—often, the demand might be around 1,200 units, while the supply might be around 800 units. Consequently, the quantity bought and sold is limited by the lower of the two, which is the quantity supplied, indicating that supply constraints dictate the final traded quantity when prices are below equilibrium.

Conversely, when the price of pineapples is $3, the quantity demanded decreases, and the quantity supplied increases, moving closer to the equilibrium point. The demand might fall to approximately 1,000 units, while supply increases to roughly 1,200 units. Here, the market experiences a surplus, meaning the quantity supplied exceeds the quantity demanded. The actual traded quantity is determined by the lesser of supply and demand—in this case, around 1,000 units—reflecting that demand limits the quantity exchanged when prices are above or below equilibrium.

Part 4 and 5: Quantities Bought and Sold at Different Prices

At a price of $3 per apple, the quantity demanded might be around 1,000 units, with the quantity supplied approximately 1,200 units. The market clearing occurs at the lower of these two figures, implying about 1,000 apples are bought and sold. The surplus of 200 apples remains unsold, indicating market disequilibrium at this price. The same analysis applies at $4 per apple, where the quantities align more closely with equilibrium conditions.

This examination illustrates that when market prices are above equilibrium, supply drives the quantity of goods sold, leading to surpluses. When prices are below equilibrium, demand constrains sales, leading to shortages. Ultimately, market forces—either supply or demand—determine how many units are bought and sold at these price points, striving toward an equilibrium state.

Gains from Trade Between the United States and China

Trading between nations, such as the United States and China, generates gains from specialization and comparative advantage. Each country's ability to produce goods like cars and phones efficiently influences trade patterns and profitability. For example, both countries initially produce goods for domestic consumption, with 1,000 units allocated to each product per country, based on 2,000 workers.

The trade terms specify that 2,000 cars can be exchanged for 14,000 phones. This ratio determines the comparative advantage and potential trade gains. Assumptions suggest that the US and China can shift resources to produce either cars or phones efficiently, depending on their productivity and costs. For instance, if the US has a comparative advantage in cars, it will produce more cars and specialize, trading excess cars for Chinese phones, which are comparatively cheaper for China to produce.

Analyzing the production before trade reveals both countries are on the cusp of maximizing their output with current resources, each using 1,000 workers for each good. After trade, the countries can specialize further, increasing consumer welfare by enabling higher consumption beyond domestic production possibilities. The change in consumption patterns post-trade is illustrated in the table provided, demonstrating how gains from trade allow both countries to consume more than they could through autarky alone.

This process highlights the importance of comparative advantage, trade terms, and resource allocation in international trade. The ability of nations to leverage their productivity differences results in welfare improvements, enhanced resource efficiency, and economic growth. These insights are crucial for understanding global economic interdependence and policy implications related to free trade agreements and tariffs.

Conclusion

Understanding market equilibrium and the forces that drive supply and demand is vital for analyzing how markets function. In addition, international trade principles like comparative advantage and trade terms significantly influence how countries can maximize gains and improve consumer welfare. By studying specific cases for pineapples, apples, and international trade between the US and China, students gain a comprehensive view of economic interactions in both domestic and global markets.
