By______spending or______taxes, a government can close the GDP gap.

An element of fiscal policy that changes automatically as income changes.

A system in which banks keep less than 100 percent of their deposits available for withdrawal.

a) A stock has traded at an average price of $50 over the course of a trading day. The covariance of successive transaction price changes (trade-by-trade changes in price) is about -0.06. Using the Roll model, what is the estimate of the bid-ask spread of the stock (measured in percent of the average price of $50)?

b) The market index has average return 7% and standard deviation 30%. The risk-free rate is 3%. A portfolio has beta 1.4, unsystematic variance of 0.03,and an M2-measure of -0.01. What is the average return on the portfolio?

What evidence has been cited to support that humans have altered the planet sufficiently to place us into a new geological epoch, called the Anthropocene?

1.Describe the changes that have taken place in the structure of the Australian financial system over the past 30 years (in terms of the relative size and importance of each category of financial institution).  Why do you think some of these changes have occurred? (You do not need to quote specific percentages – just indicate which categories have increased or decreased in importance.

2.Describe how an ADI determines the optimal mix of liabilities, and the strategies it can employ to attract both deposit and non?deposit funding.

Minden Company manufactures a high-quality wooden birdhouse that sells for $25
per unit. Variable costs are $12 per unit, and fixed costs total $210,000. The
company sold 30,000 birdhouses to customers during 2020. The president of
Minden Company believes the following changes should be made in 2021:

1. the selling price of the birdhouse should be reduced by 20%

2. increase advertising by $33,000

Assume these changes are made. Calculate the number of units Minden Company
must sell in 2021 in order to break-even.

5. Assume the demand for plastic surgery is price inelastic. Are the following statements true of false? Explain.

a. When the price of plastic surgery increases, the number of operations decreases.

b. The percentage change in the price of plastic surgery is less than the percentage change in quantity demanded.

c. Changes in the price of plastic surgery do not effect the number of operations.

d. Quantity demanded is quite responsive to changes in price.

e. If more plastic surgery is performed, expenditures on plastic surgery will decrease.

f. The marginal revenue of another operationis negative.

TOPIC- Write about the environmental factors that affect your behavior. This can include the effects of time, atmosphere or shopping. behavior.

Paragraph 1 will explore the week’s topic(s) and link it to how it influences your behavior.
Paragraph 2 will describe changes in your behavior this week, and how the behavior is changing

Paragraph 3 how you do this week? any changes and what results did you see?

(Behavior that I want to change is: I will exercise at least 4 times every week.)

Review the influence of mass extinctions on animal diversification. First, in one paragraph define the key geological periods in animal diversification associated with large-scale changes in diversity (3 marks). In the next paragraph, briefly describe any associations between mass extinctions and key geological periods, using several examples from Biol 227 (4 marks). In your final paragraph discuss the role of mass extinctions have had in animal diversification, focusing on key environmental changes and their consequences (3 marks).

Consider a CSTR where a simple first-order reaction takes place. The rate constant depends on the reactor temperature and can be given the Arrhenius equation. The reactor contents are cooled by a coolant that flows through a jacket around the reactor. Derive the dynamic model of the CSTR. i.e. the change of concentration of component A and the temperature of the reactor, assuming the flow rate and the inlet conditions are constant. You can use linearization technique for this coupled system.

Derive the transfer function relating changes in the reactor concentration to changes (C) in the coolant temperature (Tc).

You sequence the DNA of the organism, and it was normal at this location, with no mutations. You sequence the mRNA, and it was also normal. Based on your knowledge of protein translation, and any changes in the peptide that you recover, you assume that there has been some of type of change in the translational, not post-translational mechanism due to the radiation. What is/are a plausible guess to the explain the changes in the peptide recovered versus the one predicted and what type of potential change/mutation may have occurred in translation machinery to lead to this effect? Explain your logic and answer.
