Structuralism: The First School of Psychology

Structuralism was the first systematic school of psychology. It was founded by Wilhelm Wundt and further developed by Edward B. Titchener.

• Focus: The structure of consciousness.
• Method: Introspection.
• Goal: To identify basic elements such as sensations, feelings, and images.

Structuralism treated the mind like a chemical compound. Its primary contribution was making psychology a separate scientific discipline. However, it faced criticism because introspection is subjective, it ignored the function of the mind, and it was not applicable to children or animals.

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" »
