Questionsscenario 1172 A City Has Learned That By Buying Larger Garb

Questions scenario 1172: A city has determined that purchasing larger garbage trucks could reduce labor costs associated with garbage removal. The initial cost of the trucks is $400,000. The annual savings in this year's constant dollars amount to $90,000. These trucks are expected to last for four years, after which they can be sold for $100,000. The city has the option to borrow money at a 7% discount rate to fund the purchase. Inflation during this period is expected to average 3%. All dollar amounts are expressed in this year's dollars (constant dollars), and costs and benefits are assumed to occur at the end of each year. The key question is whether the city should proceed with the purchase based on net present value (NPV) considerations.

Paper For Above instruction

Analyzing whether the city should purchase the larger garbage trucks involves a comprehensive financial evaluation that considers present value calculations, inflation adjustments, and investment risks. This decision-making process exemplifies capital budgeting principles, where future cash flows are discounted to their current value to assess the project's profitability. The following sections explore these aspects in detail, providing an evidence-based recommendation rooted in financial theory and municipal investment criteria.

Introduction

The decision to invest in large-scale infrastructure, such as garbage trucks, requires a careful analysis of the financial implications and potential benefits. Given the initial expenditure of $400,000, annual savings of $90,000, an expected residual value, and the ability to finance the project at prevailing interest rates, the city must determine if the investment yields a positive net present value. The evaluation also considers inflation's impact on real versus nominal dollars and compares different borrowing scenarios to identify the most advantageous financing option.

Financial Analysis and Methodology

The core of the analysis utilizes net present value (NPV) calculations, which involve discounting future cash flows—savings and residual value—at the appropriate interest rate to determine their current worth. The formula for NPV is:

NPV = -Initial Investment + Σ (Cash flows at end of year / (1 + discount rate)^year) + Residual Value / (1 + discount rate)^n

In this context, all cash flows—costs, benefits (savings), and residual value—are treated as occurring at year's end, aligning with standard capital budgeting practices.

Calculating Present Value of Costs and Benefits

• Initial cost: $400,000 (outflow at time zero).
• Annual savings: $90,000 each year for four years, representing inflows, assumed to occur at the end of each year.
• Residual value at year four: $100,000, representing a salvage inflow.

Using the nominal discount rate of 7%, we discount each year's savings and residual value accordingly. The present value (PV) of an annuity of $90,000 over four years at 7% is calculated using the annuity formula:

PV = Cash flow × [(1 - (1 + r)^-n) / r]

where r = 0.07 and n = 4.

Similarly, the present value of the residual value is computed as:

PV residual = $100,000 / (1 + 0.07)^4

This results in a total PV of benefits, which, combined with the residual value, is compared against the initial cost to determine NPV.

Inflation Adjustment and Real Dollars

While the dollar amounts are expressed in constant dollars, the consideration of inflation is crucial when evaluating different financing options and understanding future cash flows' real value. Since inflation averages 3%, the real discount rate can be approximated using the Fisher equation:

real rate ≈ (1 + nominal rate) / (1 + inflation rate) - 1

This adjustment affects the real valuation of benefits and costs, particularly when comparing scenarios with different inflation expectations.

Scenario Analysis for Various Lenders

The analysis extends to three lending scenarios with different interest rates and inflation expectations:

• Standard lender: 7% rate, 3% inflation.
• Alternate lender 1: 7.5% rate, 4% inflation.
• Alternate lender 2: 6.5% rate, 1% inflation.

Calculations involve discounting cash flows at these rates, adjusting for inflation accordingly, and determining the respective NPVs. The lender offering the highest NPV indicates the most financially advantageous borrowing scenario, influencing the final investment decision.

Results and Interpretation

For the standard lender, the NPV calculation yields a positive value, suggesting that the city benefits financially from the investment. When considering alternate lenders, the scenario with 7.5% interest and 4% inflation (lender 1) also produces a high NPV, whereas the 6.5% interest at 1% inflation (lender 2) yields a negative NPV, indicating the project may not be financially feasible under that scenario.

Based on the comprehensive analysis, the decision hinges on the selected financing option. If the city can secure a loan at 7% with 3% inflation, purchasing the trucks is justified. The scenario with the highest NPV—likely from lender 1—also indicates a positive return, reinforcing the investment decision.

Conclusion

The financial evaluation demonstrates that, under the prevailing assumptions, purchasing the larger garbage trucks is a sound investment for the city. The positive NPVs across different borrowing scenarios, especially with the standard and alternate lender 1, confirm the project's profitability. Careful consideration of interest rates and inflation rates is essential, as adverse scenarios could diminish benefits or increase costs. Ultimately, the best approach is to proceed with the purchase using the most favorable borrowing terms, which, according to the analysis, align with the standard lender or lender 1 options.
