Unit 4 Bu224 Assignment Templateunit 4 Assignment Elasticity Of Dem

In this assignment, you will focus on marginal utility, Price Elasticity of Demand, and understanding the difference between Price Elasticity of Demand and Income Elasticity of Demand. You will analyze scenarios involving consumer choices, demand elasticity calculations, and the effects of price and income changes on demand and revenue. Answer all questions thoroughly, providing explanations, calculations, and examples where applicable, and include citations in APA format for any sources referenced.

Sample Paper For Above instruction

The concept of elasticity in economics is vital for understanding how consumers and markets respond to changes in prices and income. Elasticity measures the sensitivity of demand or supply to changes in these variables, which in turn influences business strategies and government policy-making. This paper examines the application of utility maximization principles, demand elasticity calculations, and the differentiations between price elasticity and income elasticity, through detailed scenario analysis and quantitative calculations.

Question 1: Utility Maximization and Consumer Choice

Jane, having worked all day and missing her meals, is hungry and has a $20 budget to allocate between grilled chicken sandwiches and fries. She assigns marginal utility scores to each item as she consumes more, which decrease due to the law of diminishing marginal utility. Her total expenditure on each item, total utility, and the utility per dollar are documented. The question asks whether Jane is maximizing her utility and what adjustments she should make.

Based on the provided data, Jane spends $12 on three chicken sandwiches and $6 on three fries, leaving $2 unspent. The total utility derived from these purchases is 308, with marginal utilities decreasing as she consumes more. To determine if she maximizes her utility, we compare the marginal utility per dollar for the last units purchased. When marginal utility per dollar for chicken sandwiches is lower than that for fries, reallocating spending on these items could increase total utility.

Calculations show that the marginal utility per dollar for the third sandwich is 4.6, while for the third fry it is 3.8. Since the marginal utility per dollar of fries exceeds that of sandwiches, Jane could increase her overall utility by purchasing fewer sandwiches and more fries. This reallocation balances the marginal utility per dollar, aligning with the consumer’s optimal consumption rule where the last dollar spent on each good yields the same satisfaction.

Implication of the Law of Diminishing Marginal Utility

This law suggests that as consumption of a good increases, the additional satisfaction from consuming an extra unit diminishes. Therefore, consumers tend to redistribute their spending toward goods that offer higher marginal utility per dollar until equilibrium is reached. In Jane’s case, reducing one sandwich and purchasing more fries would lead to a higher total utility, exemplifying the principle in action.

Question 2: Demand Elasticity and Revenue Impact

The Gondwanaland gosum berry growers, faced with a decrease in production due to pests, experienced a rise in price from $70 to $84 per barrel, with demand falling from 700 to 600 barrels monthly. Using the midpoint (arc) elasticity formula, the price elasticity of demand can be calculated as:

Elasticity = \[ \frac{(Q2 - Q1)}{(Q2 + Q1)/2} \div \frac{(P2 - P1)}{(P2 + P1)/2} \]

Substituting the values:

  • Q1 = 700, Q2 = 600
  • P1 = 70, P2 = 84

Calculating numerator:

(600 - 700) / (600 + 700)/2 = -100 / 650 ≈ -0.1538

Calculating denominator:

p> (84 - 70) / (84 + 70)/2 = 14 / 77 ≈ 0.1818

Thus, elasticity = -0.1538 / 0.1818 ≈ -0.846, which in absolute value is 0.846. This indicates demand is inelastic since elasticity

Revenue Changes

Year 107 total revenue:

Price × Quantity = $70 × 700 = $49,000

Year 108 total revenue:

$84 × 600 = $50,400

Change in revenue = $50,400 - $49,000 = $1,400 increase

Despite the decrease in quantity demanded, total revenue increased because the demand is inelastic; thus, the price increase more than compensated for the decrease in quantity, raising total revenue.

Prediction of Revenue Change

Given the elasticity value, a price increase results in a less than proportional decrease in quantity demanded, leading to an increase in total revenue. Conversely, if demand had been elastic (elasticity > 1), higher prices would reduce total revenue. This illustrates how elasticity measures guide revenue strategies for producers and policymakers.

Question 3: Elasticity of Demand for Consumers

The Altair chariots have a price elasticity of demand of 3 and an income elasticity of 2. Consider the statements:

  • a. A 20% increase in price leads to:

Percentage change in quantity demanded = Elasticity × Percentage change in price = 3 × 20% = 60%. This indicates demand would fall by 60%, which is a significant decrease. The statement is true.

  • b. An increase in consumer income would lead to:

Since the income elasticity is positive at 2, an increase in incomes would increase demand, and higher prices would follow due to higher demand. The total quantity demanded would increase alongside prices, affirming the statement as true.

Conclusion

Understanding demand elasticity enables firms and policymakers to make informed decisions about pricing, output levels, and income policies. In consumer behavior analysis, marginal utility guides optimal consumption choices, while elasticity calculations predict how prices and income changes affect demand and revenue. Mastery of these concepts supports efficient market functioning and strategic decision-making.
