Algebraic Look at the Result of Demographic Changes Under a Pay-as-You-Go system

A) Please explain the following formula

t=(B/W)*(R/L)

t = B/W × R/L = the average replacement rate × the dependency ratio

t = total benefits paid
B = the average benefit
R = the number of recipients
W = taxable wages
L = the number of workers

B) What are the main differences between a pay-as-you-go (PAYG) pension system and capital-funded pension system?

C) What is the major problem of a PAYG system? Please explain it in a few sentences and the formula above.

D) What is a major problem of capital funded pension systems?   

1. Understand the process of vaporization and how it changes with temperature, surface area, and the degree of intermolecular forces.

2. Understand that molecules or atoms have a distribution of thermal energies that changes as a function of temperature.

3.Know that the heat of vaporization, DH_vap, is a quantitative measure for the process of vaporization.

4. Calculate and interconvert mass, moles, and energy using the heat of vaporization.

5 Know and understand how vapor pressure and dynamic equilibrium dictate vaporization and condensation.

6 Know that the vapor pressure of a liquid depends on temperature and that the boiling point of a liquid depends on the external pressure.

7 Use the Clausius-Clapeyron equation to relate temperature and vapor pressure.

8. Define critical temperature and critical pressure.

You just discovered, for the first time, that LTP causes learning. Describe the molecular changes involved in LTP. The answer should include: how AMPA and NMDA receptors are different, why this matters, how a particular protein kinase is activated, two important ways this protein kinase contributes to LTP, how a particular transcription factor is activated, how the transcription factor contributes to LTP, how retrograde messengers contribute.

How are chemical changes summarized in a form of balanced chemical equations? What important reaction information is needed to write a complete balanced chemical equation?

Why is it necessary to write a balanced equation to completely understand the chemical properties of the reactants and products, and predict if a reaction has occurred or not?

1. Two reactions involving L-amino acids and the values of their respective free-energy changes are as follows:

            Glutamate + pyruvate « a-ketoglutarate + alanine

                                                DG°‘ = -2.4 kcal/mol

            Glutamate + oxaloacetate « a-ketoglutarate + aspartate

                                                DG°‘ = -11.5 kcal/mol

            a) Write the overall reaction for production of alanine and oxaloacetate from aspartate and pyruvate.

            b) Show that under standard conditions the net formation of alanine and oxaloacetate from aspartate and pyruvate is thermodynamically unfavorable.

            c) Suppose that at 25 °C, the molar concentrations of reactants and products are as follows:

            [pyruvate] = [aspartate] = 10 ^-2 M

            [alanine] = 10^-4 M

            [oxaloacetate] = 10^-5 M

Is the spontaneous synthesis of alanine and oxaloacetate possible under these conditions?

Q1. Price elasticity of demand measures

A) how responsive suppliers are to price changes.

B) how responsive sales are to changes in the price of a related good.

C) how responsive quantity demanded is to a change in price.

D) how responsive sales are to a change in buyers' incomes.

Q2. Suppose the value of the price elasticity of demand is -3. What does this mean?

A) A 1 percent increase in the price of the good causes quantity demanded to increase by 3 percent.

B) A 1 percent increase in the price of the good causes quantity demanded to decrease by 3 percent.

C) A 3 percent increase in the price of the good causes quantity demanded to decrease by 1 percent.

D) A $1 increase in price causes quantity demanded to fall by 3 units.

Q3. If the percentage increase in price is 15 percent and the value of the price elasticity of demand is - 3, then quantity demanded

A) will increase by 45 percent. B) will increase by 5 percent.

C) will decrease by 45 percent. D) will decrease by 5 percent.

Q4. If 50 units are sold at a price of $20 and 80 units are sold at a price of $15, what is the absolute value of the price elasticity of demand? Use the midpoint formula.

A) 0.17 B) 0.62 C) 1.62 D) 5

Q.5 Rank these three items in terms of the elasticity of the demand for them at any given price, from most elastic to least elastic: hot beverages, coffee and Peets' Coffee.

A) hot beverages, coffee, Peets' Coffee

B) Peets' Coffee, coffee, hot beverages

C) coffee, Peets' Coffee, hot beverages

D) coffee, hot beverages, Peets' Coffee

Q.6. Income elasticity measures

B) how a good's quantity demanded responds to change in the price of another good.

C) how a good's quantity demanded responds to change in buyers' incomes.

D) how a good's quantity demanded responds to producers' incomes.

Q.7 Last year, Sefton purchased 60 pounds of potatoes to feed his family of five when his household income was $30,000. This year, his household income fell to $20,000 and Sefton purchased 80 pounds of potatoes. All else constant, Sefton's income elasticity of demand for potatoes is

A) negative, so Sefton considers potatoes to be an inferior good.

B) positive, so Sefton considers potatoes to be an inferior good.

C) positive, so Sefton considers potatoes to be a normal good and a necessity.

D) negative, so Sefton considers potatoes to be a normal good.
