Environmental Economics: True Or False? Explain The Demand F

Environmental Economicstrue Or False Explainthe Demand For Oil In Al

Environmental Economics TRUE OR FALSE - EXPLAIN The demand for oil in Alaska is given by 8−0.4q while the supply is 2. If Alaska has 20 barrels of oil for two years and the interest rate is 10%, it is better for Alaska to extract 5 barrels in year one and 15 barrels in year two than to extract 15 barrels in year one and 5 barrels in year two. Alaska follows the Hotelling rule in their decision to extract oil. In 2017, the marginal extraction cost of oil was $2 and the price of oil was $2.70. In 2018, the marginal extraction cost was $2.2 while the price was $3. What was the interest rate in Alaska? MULTIPLE CHOICE 1. Water is the main production input for the beer brewing companies in Milwaukee and therefore, their profits heavily depend on the price of water. The marginal cost of all brewing companies is 300 + 0.8Q where Q is gallons of water. Notice, however, that 0.4Q of that cost comes from the water embedded in wheat, which is also used for beer production. Brewing companies use wheat produced in Kansas in the production of beer. Finally, the marginal benefit is 1200 − 1.4Q where Q is gallons of water. Consider that brewing companies are the only consumers of water in Milwaukee and that Milwaukee Water Works provides water for beer production. What is the market price of water in Milwaukee? (a) 500 (b) 409 (c) 627 (d) none of the above. 2. Suppose the demand for oil in Alaska is given by 8−0.4q while the supply is 2. Alaska only consumes its oil and the stock of oil is equal to 20 barrels for two years. If the interest rate is 10%, the government of Alaska will extract: (a) X1 = 5 barrels in year one and X2 = 15 barrels in year two. (b) X1 = 15 barrels in year one and X2 = 5 barrels in year two. (c) X1 = 12.039 barrels in year one and X2 = 7.961 barrels in year two. (d) X1 = 11.278 barrels in year one and X2 = 8.722 barrels in year two. (e) None of the above.

The provided scenario explores several facets of environmental economics, focusing primarily on resource management, specifically oil extraction in Alaska, water pricing in Milwaukee, and economic decision-making under scarcity and discounting. Additionally, it prompts an examination of the Hotelling model in resource depletion, marginal costs, and benefits in water economics, and the implications of economic principles for sustainable resource utilization.

Understanding the Hotelling Rule and Alaska’s Oil Extraction Strategy

The Hotelling rule provides a fundamental principle in resource economics, stating that theOptimal extraction rate of a non-renewable resource should reflect the increase in resource value over time, accounting for the discount rate. It posits that the net price of resource extraction, adjusted for marginal costs, should grow at the rate of interest. When applying this to Alaska’s oil reserves, the demand function is given as 8−0.4q, with a supply of 2, indicating a market where demand decreases as quantity increases, with supply being constant.

Alaska's total oil stock of 20 barrels over two years presents a strategic decision problem: whether to extract more in the initial period or defer extraction to the future, balancing present consumption with future scarcity. The decision hinges on the interest rate, as it influences the present value of future benefits. The question asks which extraction schedule aligns with the Hotelling rule, implying that the marginal profit from extraction should grow at the discount rate.

Calculating the Interest Rate from Oil Prices and Costs

In 2017, the marginal cost (MC) was $2, with a price of $2.70, and in 2018, the MC was $2.2 with a price of $3. The price increase reflects resource devaluation or scarcity effects, and the marginal cost change indicates technological or operational improvements.

The interest rate (r) in Alaska can be inferred through the relationship between prices and costs across years, following the principles of the Hotelling rule. The rule suggests that the ratio of future to current prices should relate to (1 + r), adjusted for costs. Mathematically, this is expressed as:

\[ \frac{P_{2018} - MC_{2018}}{P_{2017} - MC_{2017}} = (1 + r) \]

Plugging in the values:

\[ \frac{3 - 2.2}{2.7 - 2} = \frac{0.8}{0.7} \approx 1.14 \]

Thus, \[ 1 + r \approx 1.14 \], leading to r ≈ 14%, which uniquely aligns with one of the multiple-choice options, likely close to approximately 12-15%. This calculation indicates a significant opportunity cost of delaying extraction, consistent with the Hotelling rule.

Water Pricing and Market Equilibrium in Milwaukee

The costs for brewing companies include both direct costs and embedded water costs. The marginal cost function, 300 + 0.8Q, includes 0.4Q attributed to water embedded in wheat, implying that the total marginal cost includes costs independent of water, plus an embedded water component. The marginal benefit function, 1200 − 1.4Q, reflects the demand side where higher quantities reduce marginal benefit due to diminishing returns or saturation effects.

To find the market price, the equilibrium occurs where marginal cost equals marginal benefit. Setting the cost function equal to the benefit function allows us to determine the optimal quantity Q and the corresponding price.

Solving for Q:

\[ 300 + 0.8Q = 1200 - 1.4Q \]

\[ 0.8Q + 1.4Q = 1200 - 300 \]

\[ 2.2Q = 900 \]

\[ Q = \frac{900}{2.2} \approx 409 \] gallons

The market price of water at this equilibrium is then: cost at Q=409

\[ P = 300 + 0.8 \times 409 \approx 300 + 327.2 = 627.2 \] dollars

Matching this to the options, (c) 627 is the closest and most accurate, confirming the market equilibrium price of water in Milwaukee aligns with the supply and demand balance.

Resource Allocation and Optimal Extraction in Alaska

Considering the demand function 8−0.4q, the supply of 2, and a stock of 20 barrels, the crucial question revolves around optimal extraction over two periods to maximize the present value under a 10% discount rate.

The optimal temporal distribution of extraction is derived from dynamic optimization models that incorporate marginal revenues, costs, and the discount rate, consistent with the Hotelling rule. The calculation involves solving for the quantities \(X_1\) and \(X_2\) that satisfy the following conditions:

• The sum of extraction over two periods equals total initial stock: \(X_1 + X_2 = 20\).
• The marginal benefit of extracting today equals the discounted marginal benefit of extracting tomorrow, adjusted for the increase in resource value, which involves setting the marginal revenue in each period equal after discounting.

Using the formula for the present value of future benefits and the Hotelling rule, the optimal extraction schedules correspond to options (c) and (d). The calculation for \(X_1 \approx 12.039\) and \(X_2 \approx 7.961\) barrels responds well to the demand and cost parameters, satisfying the equilibrium condition, considering the discount rate and resource constraints.

Conclusion

This set of problems illustrates the application of core principles in environmental and resource economics, including the Hotelling model, marginal analysis, and intertemporal decision-making. The analysis underscores how economic incentives influence resource extraction and pricing, guiding sustainable management strategies aligned with market forces and long-term planning.
