6. A ) Suppose you are working as an economic consultant and you are supposed to explain the consequences of the following cases to your clients. Answer each part separately.

   1. Suppose due to a war in a neighbouring country, the country received refugees which increased the labour force. Also, there is a huge reduction in global oil prices. By using the Aggregate Supply curve, show the possible effects of these two changes on the price level and aggregate output in the Short-Run. Explain each step in your graph.

   2. Suppose there is an increase in interest rate. By using the Aggregate Expenditure (AE) – Aggregate Output (Y) graph, show the effects of this change on AE and Y in the Short-Run. Then, show the effect of increased interest rate by using the IS curve, explain what will happen to the IS curve.

   3. Now suppose government expenditure (G) increases and there is an increase in the overall price level (P). By using the IS curve and Fed (Central Bank) Rule curve graph, explain the effect of these changes on the interest rate and output in the Short- Run. Explain each step in your graph.

   4. Now assume that there is an increase in government expenditure (G), an increase in the labour force and a reduction in oil prices. By using the AS-AD graph, explain the effects of these changes on equilibrium output and equilibrium price level in the Short-Run. Explain each step in your graph.

   5. Now assume that for some reason Aggregate Demand shifts to the left (downwards) and suppose wages fully adjust. By using the AS-AD graph, show the effects of this shift on the equilibrium output and price level in the Short-Run and in the Long-run.

Mary Willis is the advertising manager for Bargain Shoe Store. She is currently working on a major promotional campaign. Her ideas include the installation of a new lighting system and increased display space that will add $36,000 in fixed costs to the $272,000 currently spent. In addition, Mary is proposing that a 5% price decrease ($40 to $38) will produce a 20% increase in sales volume (20,000 to 24,000). Variable costs will remain at $24 per pair of shoes. Management is impressed with Mary’s ideas but concerned about the effects that these changes will have on the break-even point and the margin of safety.

Compute the current break-even point in units, and compare it to the break-even point in units if Mary’s ideas are used. (Round answers to 0 decimal places, e.g. 1,225.)

Prepare a CVP income statement for current operations and after Mary’s changes are introduced.

PDQ Repairs has 200 auto-maintenance service outlets nationwide. It performs primarily two lines of service: oil changes and brake repair. Oil change–related services represent 70% of its sales and provide a contribution margin ratio of 20%. Brake repair represents 30% of its sales and provides a 30% contribution margin ratio. The company’s fixed costs are $15,552,600 (that is, $77,763 per service outlet).

(a)

Calculate the dollar amount of each type of service that the company must provide in order to break even. (Use Weighted-Average Contribution Margin Ratio rounded to 2 decimal places e.g. 0.25 and round final answers to 0 decimal places, e.g. 2,510.)

The company has a desired net income of $53,981 per service outlet. What is the dollar amount of each type of service that must be performed by each service outlet to meet its target net income per outlet? (Use Weighted-Average Contribution Margin Ratio rounded to 2 decimal places e.g. 0.25 and round final answers to 0 decimal places, e.g. 2,510.)

Choose the FALSE statement:

A) Based on principles of artificial selection, dairy farmers should be able to change the genetic makeup of their livestock so that new generations evolve to produce more milk.

B) Based on a comparison of their structure, the wings of bats and dragonflies can be considered to be homologousstructures, and thus, products of divergent evolution.

C) Lyell and Hutton‘s observations that slow geological changes gradually shaped the earth provided Darwin with the idea that Nature could gradually determine the shape of life.

Multiple choice: Choose the CORRECT statement as it relates to the figures:

A) the two limb structures shown are examples of analogous structures.

B) the two limb structures shown are completely unrelated, and any resemblance between the two is merely coincidental.

C) the two limb structures shown are homologous to one another and provide evidence of common ancestry.

D) the two limb structures shown are an example of convergent evolution.

Multiple choice: Which of the following statements about pattern formation genes (e.g., the Hox genes) is CORRECT:

A) They provide a means of explaining how a mutation in a single gene can result in significant evolutionary changes, including the rapid appearance of complex structures.

B) An understanding of how these genes operate helps us explain punctuated equilibrium eliminates the notion that the fossil record should contain innumerable numbers of transitional forms.

C) Our understanding of these genes confirms that microevolutionary principles can be applied equally to account for micro- and macroevolutionary changes.

D) a and b are correct

Assume that you are the international trade manager of XYZ Inc. Because your firm exports goods, to Mexico, your job as international trade manger requires you to forecast the value of year, your firm exported one-billion-peso worth of products to Mexico. The exchange rate between US dollar and Mexican peso was $.02/peso. Now, you are expecting that the following changes will take place in the markets. Assume that everything else remains the same.

1. Last year, the inflation rate in the US was 3% and 8% in Mexico. Now, you are expecting that the following change will take place in the markets. Next, year, the inflation in the US is expected to be 2% while it will increase to 9% in Mexico. With each percentage change in the differential inflation, there will be a 5% change in the demand for exports by the Mexican customers. In addition, for each percentage change in the differential inflation, there will be a 1.5% change in the value of the Mexican peso. Explain how the above changes will affect the value of exports of your company to Mexico.

2. Last year, GDP growth rate in the US was 2.5% while it was 3% in Mexico. Next year, you expect that the national income of US will increase by 3% while Mexican national income, will increase by 4.5%. for each percentage change in the differential national income, there will be a 3% change in the differential national income, there will be a 2% change in the value of the peso. Explain how the above changes will affect the value of exports of your company to Mexico.
