Explain With Demand And Supply Diagrams The Eff

Explain, with the use of demand and supply diagrams, the effect of the following events on the market for solar panels

Question 1 requires an analysis of how specific events impact the market for solar panels using demand and supply diagrams, along with explanations of the market equilibrium adjustment process. The events include a fall in the price of solar panels below the equilibrium, an increase in electricity prices, and technological improvements in solar panel production.

The market for solar panels is dynamically influenced by various external and internal factors, which can significantly alter the market equilibrium—where the quantity of solar panels demanded equals the quantity supplied at a given price. To understand these impacts, demand and supply diagrams serve as effective tools to visualize the shifts and resultant price and quantity changes.

Impact of the Price of Solar Panels Falling Below the Market Equilibrium

If the price of solar panels drops below the market equilibrium price, it creates a situation where the quantity demanded exceeds the quantity supplied, leading to a shortage. This situation exerts upward pressure on prices as consumers seek to purchase more than producers are willing to supply at the lower price. In the demand and supply diagram, the price line moves below the equilibrium point, causing a shortage, which eventually results in an increase in the price. As the price rises back toward the equilibrium, the quantity supplied increases while the quantity demanded decreases, restoring market equilibrium at a higher price and quantity.

Impact of an Increase in Electricity Prices by 50 Percent

When electricity prices rise significantly, the attractiveness of solar panels as an alternative energy source increases. This shifts the demand curve for solar panels to the right, indicating higher demand at each price level. On the demand and supply diagram, this rightward shift causes the intersection point with the supply curve to move upward, resulting in a higher equilibrium price and a higher equilibrium quantity of solar panels. The market adjusts through increased production as firms respond to the higher demand, leading to a new stable point where both price and quantity are elevated.

Impact of Technological Improvements Increasing Productive Efficiency

Advancements in technology that enhance the productivity of solar panel producers make it cheaper and easier to produce solar panels. This shifts the supply curve to the right, signifying increased supply at each price level. The supply curve's rightward shift causes the equilibrium price to fall and the equilibrium quantity to increase initially. Consumers benefit from lower prices, and increased production meets the higher demand, leading to a new equilibrium with a higher quantity of solar panels on the market and a reduced price level, reflecting increased market efficiency.

Market Adjustment Process

In each scenario, the economy responds to disequilibrium by adjusting prices and quantities vertically along the supply and demand curves until a new equilibrium state is reached. When supply decreases or demand increases, prices tend to rise, encouraging producers to supply more. Conversely, a technological advancement that increases supply causes prices to fall, incentivizing consumers to purchase more. These adjustments demonstrate the self-correcting nature of markets as they tend toward equilibrium, balancing supply and demand dynamically.

Impact of Regulations on the Market for Yoga Services

The simultaneous increase in demand for yoga services, coupled with stricter government regulations reducing the number of providers, presents a complex effect on the market. In demand and supply analysis, these two factors produce competing effects—demand shifts to the right while supply shifts to the left. The net impact on price and quantity depends on the relative magnitude of these shifts.

Scenario 1: Demand Increase with No Change in Supply

Initially, an increase in demand, represented by a rightward shift of the demand curve, exerts upward pressure on both price and quantity. However, the introduction of stringent regulations reduces the number of providers, effectively decreasing supply, which shifts the supply curve leftward. This decrease in supply amplifies the upward pressure on price and causes the quantity to decrease compared to the initial demand increase scenario.

Scenario 2: Both Shifts Occur Simultaneously

When demand increases and supply decreases simultaneously, the market experiences conflicting forces. The demand increase tends to raise both price and quantity, while the decrease in supply pushes prices even higher but reduces quantity. The new equilibrium will be at a higher price but ambiguous in terms of quantity—it could fall, stay the same, or increase depending on the magnitude of shifts. The dominant effect is likely a significant increase in price, with quantity potentially decreasing due to supply constraints.

Market Dynamics in the Market for Life Chickens During Bird Flu Outbreak

The outbreak of Bird Flu in 1997 led to two simultaneous events: mass culling of chickens (a decrease in supply) and a decline in consumer demand due to health concerns. In demand and supply analysis, these effects are represented as shifts in the curves: a leftward shift in supply and a leftward shift in demand.

Impact of Reduced Supply

The culling reduces the number of chickens available, shifting the supply curve leftward. This typically causes the equilibrium price to rise and the quantity to decrease, reflecting scarcity and higher prices due to reduced availability.

Impact of Decreased Consumer Demand

Simultaneously, consumer fears about disease lead to a decrease in demand, shifting the demand curve leftward. This causes the equilibrium price to fall and the quantity to decrease further, exacerbating the reduction in quantities traded in the market.

Combined Effect

The overall impact depends on the relative magnitudes of the shifts. Since both supply and demand decrease, the equilibrium quantity unambiguously declines. The effect on price is ambiguous: if the supply decrease is larger than demand reduction, prices may rise; if demand drops more significantly, prices could fall or stabilize at a lower level. Overall, the market experiences a significant contraction with reduced transactions and mixed price movements.

Price Elasticity of Demand and Total Revenue

When the price of a good increases from $6 to $8, and the quantity demanded decreases from 50 to 40 units, the price elasticity of demand can be calculated as follows:

Elasticity = (% change in quantity demanded) / (% change in price)

% change in quantity demanded = ((40 - 50) / 50) = -0.2 or -20%

% change in price = ((8 - 6) / 6) = 0.333 or 33.3%

Elasticity = -0.2 / 0.333 ≈ -0.6

This indicates the demand is inelastic because the absolute value of elasticity is less than 1.

In terms of total revenue:

Total Revenue (TR) before the price increase = $6 × 50 units = $300

After the price increase = $8 × 40 units = $320

Since total revenue increased from $300 to $320 despite a decrease in quantity demanded, the inelastic nature of demand explains why raising prices increases total revenue in this range.

Firms’ Strategies in a Competitive Industry with No Barriers to Entry

When firms experience short-run losses in a perfectly competitive industry, they have several options to minimize losses: shutdown, reduce output, or accept losses and await changes. In the short run, firms may continue operating if revenues cover variable costs, preventing worse losses. In the long run, free entry and exit lead to adjustments in market supply, eventually restoring normal profit levels.

Demand and supply analysis shows that persistent losses drive firms to exit, decreasing supply and pushing prices upward until remaining firms earn normal profits—covering all opportunity costs. The equilibrium process involves market adjustment via entry and exit, restoring industry profitability over time.

Price and Quantity Adjustments for Normal Profit

As firms exit the market due to losses, overall supply decreases, leading to higher prices and attracting new entrants if profits emerge. Conversely, if firms operate at the minimum of their average cost in the long run, they earn normal profit, where total revenue equals total costs, and there is no incentive for further entry or exit.

Conclusion

Understanding how shifts in demand and supply influence market equilibrium is vital for analyzing real-world economic scenarios. These analyses highlight the self-correcting nature of markets, the importance of technological innovations, and strategic decision-making in competitive markets, all critical for policymakers and business stakeholders.
