Q5 Answer: The Demand And Supply Equation

Q5 Answerequate The Demand And Supply Equation

Q5 Answer equate the demand and supply equation p = 1400+700p =700p+300p 200=1000p P=200/1000 P = $0.2 Now, equate the price in any of the equation Qd = *0.2 = 1540 So, equilibrium price is $0.2 and equilibrium quantity is 1540 in the market for chocolate bars.

Q6 a) b) If the actual price in this market were above the equilibrium price, there would be excess supply and price would have to decrease so that excess supply can decrease and market reach to the equilibrium. c) If the actual price in this market were below the equilibrium price, there would be a shortage and price would have to increase so that supply can increase and market reach to the equilibrium.

Q8) Q9 Ep = % Change in Q/% Changes in P Ep = - 40/7 = -5.71.

Q10) % Change in Quantity demanded = (-0.5) (-50) = +25%. New Quantity demanded = 40 1.25 = 50 units.

Q11) Arc Elasticity of Supply.

Q12) i) For Business Travelers ii) For vacationers.

Q24) Conditions of producer’s equilibrium: (i) MR=MC (Marginal Revenue = Marginal Cost) (ii) MC must be rising at the point of equilibrium or MC curve must cut MR curve from below.

Q29 a) The opportunity cost of something is what must be forgone to acquire it. Aunt must forgo his job to open the store. b) The brother’s opportunity cost of running a hardware store for a year is $550,000 which has $500,000 for the rent and $50,000 for the job. He should not open the store as the opportunity costs are less than what he could have received if he decides to open the store and can incur a loss of $40,000 ($550,000 - $510,000).

Q30) MRTSLK = MRTSLK = Q31) APL = TPL / L, MPL = ΔTPL / ΔL.

Q33) Marginal Cost = $901, Marginal Benefit = $550 — because the marginal benefit is smaller than the cost, the offer should not be accepted.

Q37) Here, Marginal Cost would be = 601*300 = $901. Marginal Benefit = $550. Because the marginal benefit is smaller than the cost, the offer should not be accepted.

This paper provides a comprehensive analysis of key microeconomic principles, including equilibrium analysis, price elasticity, producer’s equilibrium, opportunity costs, production functions, cost structures, market structures, and other foundational concepts fundamental to understanding market dynamics. The focus is on applying theoretical models to practical scenarios, illustrating how prices are determined, how quantities adjust to maintain market equilibrium, and the factors influencing consumer and producer behavior.

The equilibrium in a market is established at the intersection of demand and supply curves. Based on the demand equation Qd = 1600 – 300P and supply equation Qs = 1400 + 700P, solving for equilibrium involves equating Qd and Qs:

1600 – 300P = 1400 + 700P

Simplifying, 200 = 1000P, thus P = 0.2, which is the equilibrium price in dollars. Substituting back into the demand equation to find equilibrium quantity:

Qd = 1600 – 300(0.2) = 1600 – 60 = 1540 units.

This result indicates that at a price of $0.2, the quantity demanded and supplied are equal at 1540 units, establishing the market equilibrium.

Price elasticity of demand measures how sensitive the quantity demanded is to changes in price. Using the midpoint method, if the price rises from SR 4 to SR 5, and demand falls from 200 units to 100 units, the price elasticity (Ep) is calculated as:

Ep = (% change in Qd) / (% change in P) = [(Q2 – Q1)/(Q2 + Q1)/2] / [(P2 – P1)/(P2 + P1)/2] = (-50 / 150) / (1 / 4.5) ≈ -5.71.

This indicates that demand is highly elastic in response to price changes.

The concept of consumer's equilibrium is analyzed under indifference curve and budget constraints. Consumers maximize utility when the marginal rate of substitution equals the ratio of prices. Marginal Utility and total utility are interconnected: as consumption increases, total utility increases at a decreasing rate due to diminishing marginal utility.

The decision to produce at a certain level depends on marginal analysis. If Marginal Revenue (MR) equals Marginal Cost (MC), the firm is at profit-maximizing output. For example, if the Marginal Cost at a production level is $901 and the Marginal Benefit (or MR) is $550, the firm should not produce further, as costs exceed benefits.

Market structures significantly influence firm behavior. In perfect competition, many firms sell identical products, and prices are determined by market supply and demand. Conversely, monopoly firms set prices above marginal costs, given their market power. The profit-maximizing quantity is where marginal revenue equals marginal cost, but in monopoly, this results in deadweight loss.

Cost concepts such as fixed costs, variable costs, average total cost (ATC), and marginal cost (MC) are critical for understanding firm decisions. For instance, when the firm’s average total cost is $301 at an output of 600 units, selling at $550 per unit yields a profit, but assessing whether to accept an offer requires analyzing marginal costs.

The law of demand states that, ceteris paribus, there is an inverse relationship between price and quantity demanded. This is visually demonstrated through demand curves slope downward. Market adjustments towards equilibrium occur through changes in price when excess supply or demand exists.

Elasticity measures are vital for understanding market responses. For example, when the price of a good drops by 7%, and demand increases by 40%, the price elasticity of demand is:

Ep = 40% / 7% ≈ -5.71, indicating a highly elastic demand.

Similarly, the concept of opportunity cost underscores the value of the next best alternative foregone. For example, the brother deciding whether to open a hardware store must consider the $50,000 annual salary foregone and the $500,000 rent costs. If the expected revenue of $510,000 does not outweigh these costs, opening the store would not be financially prudent.

Production functions, such as the Cobb-Douglas form, describe the relationship between inputs and outputs. Conditions for producers' equilibrium include equating marginal revenue and marginal cost, with the marginal cost curve rising at the equilibrium point.

Cost curves intersect at different points, with average total cost reaching its minimum where marginal cost equals average total cost. Cost analysis aids in optimal decision-making, especially under varying market conditions and cost structures.

In conclusion, microeconomic analysis provides essential insights into how markets operate through the interactions of demand and supply, the elasticity of consumers and producers, and the cost structures that influence firm behavior. These principles collectively inform strategies for maximizing profits and achieving efficient resource allocation within different market environments.
