Municipal Bond Yield Calculations

Equivalent Taxable Yield (ETY)

A municipal bond carries a coupon rate of 6.00% and is trading at par.

Required Calculation 1: ETY for a 38% Tax Bracket

What would be the equivalent taxable yield of this bond to a taxpayer in a 38% combined tax bracket?

The formula for Equivalent Taxable Yield ($r$) is:

$$r = r_m / (1 - t)$$

• $r$: Equivalent Taxable Yield
• $r_m$: Municipal Bond Yield (6.00% or 0.06)
• $t$: Tax Rate (38% or 0.38)

Calculation:

$$0.06 / (1 - 0.38) = 0.096774 \rightarrow \mathbf{9.68\%}$$

Required Calculation 2: Municipal Yield Preference

An investor is in a 40% combined federal plus state tax bracket. If corporate bonds offer 7.75% yields, what yield must municipals offer for the investor to prefer them to corporate... Continue reading "Financial Calculations: Yields, Index Returns, and Security Pricing" »

Hedging with S&P 500 Index Futures

SIF hedging: NF = V_F(antiguo) = F_o x Z. NF (Number of contracts) = V_p (portfolio value) / (V_F x B_p) (Beta). With this hedge, risk is removed. If the index goes up, the profit in the portfolio will be offset by losses in SIFs contracts and vice versa.

Example: S&P 500 falls 5%:

• In the portfolio: R_p = B_p x (-5%) = -10% of a portfolio of $10M, resulting in $9M (Final Value).
• In the SIFS contracts: S_i = 980 (S&P 500 value given) x 0.95 (100% - 5%) = 931. F_i = 931 x (1 + 0.04 x 5/12 (next month timeframe)) = 946.52. V_F = NF x (F_i - F_o) x Z (250).
• Gain on futures: V_F(New) / Equity portfolio value.
• Outcome stock portfolio: 2 x (-5%) = -10%.
• Final Value portfolio: $10M - $1M + V_F(New).

Operations: Key Questions for Value Creation

• What processes create value? Example: Amazon with its automated logistics.
• What activities support these processes? Example: Google heavily invests in R&D and qualified HR.

Macroeconomics: Key Formulas and Concepts

Key Macroeconomic Formulas

• GDP Deflator = (Nominal GDP / Real GDP) * 100
• Expenditure approach: Y = Consumption + Investment (including inventory changes) + Government purchases + Net exports
• Income approach: Y = Income = Wages + Interest + Rental income + Profits
• CPI = (Cost of base-year basket at desired-year prices / Cost of base-year basket at base-year prices) * 100
• Real value (Year Y) = Nominal value (Year X) * (CPI Year Y / CPI Year X)
• MPC = Increase in spending / Increase in income (or output)
• Expenditure multiplier = 1 / (1 - b)
• Taxation multiplier = -b / (1 - b)
• Unemployment rate = (Number of unemployed / Labor force) * 100
• LFPR (Labor Force Participation Rate) = (Labor force / Working-age population)

Political Economy: Collective Decision-Making

Lindahl Pricing

Individual Marginal Benefit (MB) curves are summed vertically to determine the Social Marginal Benefit (SMB). Efficiency is achieved at the quantity (Q) where SMB = Social Marginal Cost (SMC). While theoretically efficient, it often fails due to preference issues:

• Revelation Problem: Individuals may misrepresent their true preferences.
• Knowledge Problem: Difficulty in knowing individual preferences.
• Aggregation Problem: Challenges in combining diverse preferences.

Voting Mechanisms

Voting works effectively with single-peaked preferences (where individuals have one most preferred choice).

Problems with Voting

• Non-Single-Peaked Preferences: Can lead to cyclical outcomes, known as the voting
