Study Session 4: Economics for Valuation

Algebraic Walk Through

Hit a wall. Can anyone show me the the algebra to solve for capital’s share of factor cost given the following:

4.3% = 1.8% + 3.1(a) + 2.2%(1-a)

Thanks in advance!

Mark to Market Value of Forward Currency Contract

Hi,

In the CFAI book they explain that if you are long and the currency appreciates, then you get a cash inflow. If you are long and the currency depreciates you get a cash outflow. If you are initially short and the currency appreciates you get a cash outflow and if it depreciates an inflow. However, in one of the EOC question, a short position leads to a cash inflow when the currency appreciates.

Economics - triangular arbitrage

Reference to Kaplan, book 1, pg 273. The question asks about a triangular arbitrage of three pairs (USD/AUD, USD/MXN, MXN/AUD).

Currency Forwards (sell against, buy against, gah!!!)

I’m stumped on the language and wondered if someone here may have some rules of thumb that helped you get this through your head.

Economics section, specifically 629-631 in Volume 1 of the CFAI curriculum.  The following statements are made in a couple of places on those pages

> “…bought GBP for delivery against the AUD…” - currency quoted as AUD/GBP

> “…sell the CHF six month forward against the GBP…” - Currency quoted as CHF/GBP

> “…selling the NZD 10 million forward against the USD…” - currency quoted as USD/NZD

Economics

Hello everyone, while studying for Economics Chapter 2 that is Economic Growth and Investment Decision, I encountered a particular doubt regarding a concept, that is in demographics if Population of above the age of 64 is rising, it impacts will be negative on Long Term Economic Growth. If Population is rising between age 16 to 64, its impacts will be positive on LTEG. My question is how will Population growth below 16 years of age affect the Long Term Economic Growth?

simple or compound interest rate for currincies

I’m solving a question related to arbitrage opportunities of a currency trade. Period is 3 months. The question gives me annualized 3 month interest rates.

I thought we were supposed to use compound interest unless LIBOR is mentioned, but the answer simply divides the interest rate to four, it’s like:

Suppose that we’re given: 3 month interest rate : %16 (annualized)

Answer : interest rate for the period is %4  ( 16/4)

I’m very confused

Understanding Alpha

This question is with reference to the alpha (which is the shares of output companies compensate labor and capital with, expressed with values between 0 and 1) in the Cobb-Douglas production function: F(K,L) = KαL1-α

If a country has a capital-to-labor ratio of 1000:1 in comparison to another country which has a ratio of 500:1, what does it imply in terms of the alpha of the Cobb-Douglas function?

Growth Accounting/Solow Growth Model

Is there any difference between Solow growth model and the Growth Accounting equation/model?

Are both represented by?:

Y = A + (alpha*capital)+((1-alpha)*labor)

I’ve seen, for Solow, the alpha terms be exponents, but it makes no sense when calculating..
