Two insulation thickness alternatives have been proposed for a process steam line subject to severe weather conditions. One alternative must be selected. Estimated savings in heat loss and installation cost are given below:

b.) Useful life of 2 cm Thickness alternative is 8 years and useful life of 5 cm thickness alternative is 7 years. Which thickness would you recommend for a MARR= 9% per year and negligible market (salvage) values using Present Worth Analysis and Annual Worth Analysis ? (Use repeatability assumption)

News reports from the western United States occasionally report incidents of cattle ranchers slaughtering many newborn calves and burying them in mass graves rather than transporting them to markets. Assuming that this is rational behavior by profit-maximizing "firms," explain what economic factors may influence such behavior. Justify your answer.

In prospect theory, the interplay of overweighting of small probabilities and concavityconvexity of the value function leads to the so-called fourfold pattern of risk attitudes. Each quadrant shows an individual’s choice between two prospects (x; p) in the first row and the individual’s risk attitude in the second row.

For each quadrant, explain the individual’s risk attitude with reference to the choice between the two prospects. Show your calculations clearly.

Choose 1 of the following topics related to the Great Recession:

• The housing price bubble, collapse, foreclosures, bailout of underwater mortgages
• Subprime mortgages and derivatives, bailout of FNMA, Freddie Mac and AIG
• The banking industry crisis, bailout of commercial and investment banks

Write a 350- to 700-word analysis of 1 of the following corrective actions taken by the Federal Reserve as a result of the crisis:

• Quantitative easing
• Purchase of toxic assets from financial institutions
• Paying interest on reserve balances

Address the following in your analysis:

• Actions taken by the Federal Reserve to mitigate the crisis

• How the corrective action should prevent recurrence of a similar crisis

1.1 Each entry-level Economics undergraduate in Glasgow, Scotland, has either high or low ability. All potential employers value a high-ability worker at £18,000 per month and a low-ability worker at £9,000 per month. The supply of high-ability workers is ?? ? = 0.05(? − 2,000) and the supply of low-ability workers is ?? ? = 0.1(? − 2,000), where ? is the monthly wage.

If workers’ abilities are observable to employers, what are the equilibrium wages? How many workers of each type do employers hire? If employers do not observe workers’ abilities, what is the equilibrium wage? How many workers of each type do employers hire? What is the deadweight loss due to asymmetric information?

1. EXCHANGE RATES: AUSTRALIAN DOLLAR (AUD) [15 marks]
   1. Consider the following hypothetical (separate) events from December 2020 to December 2021:

1. Speculators are seriously concerned about long-term effects on the Australian economy of the coronavirus.
2. India and China increase their demand for Australia’s metals such as iron ore and lithium.
3. US Federal Reserve lowers the US cash rate from 1.50% to 0.50%, while the Reserve Bank of Australia raises its cash rate from 0.50% to 1.00%.

For each event, identify the specific factor and explain the likely effect on the price of the Australian Dollar (AUD) in the foreign exchange market. Use a relevant demand and supply for AUD diagram in each of your answers.

                                                                                               [9 marks]

1. b.Suppose in Australia the AUD in 2020 strongly depreciated against major currencies. Is there likely to be a contractionary or expansionary effect on the Australian economy from the depreciation of the AUD? Explain your answer.

                                                                                               [3 marks]

c) Discuss the likely effects a large appreciation of the AUD would have on: (i) consumers travelling overseas; (ii) wheat exporters; (iii) import-competing Australian firms such as manufactures. [3 marks]

Assume that effective forecasting requires a combination of technique, system support, and administration. Your supervisor in your consumer products firm has requested that you identify some initiatives to enhance forecast accuracy. What specific initiatives would you recommend for consideration regarding the technique, system support and administration components?

1. GDP, UNEMPLOYMENT and FISCAL POLICY [15 marks]

1. Describe the relevant criteria that government statisticians use in Australia to determine whether a person is ‘unemployed’. Describe two ways in which the current method of calculating official ‘unemployment rate’ in Australia has been criticised for underestimating unemployment.  

                                                                                                   [3 mark]        

2. Identify whether there is likely an increase or decrease in measured Australian GDP in the following scenarios and discuss whether GDP is a ‘good’ measure of progress in each case:

1. a major increase in the extraction of coal to meet electricity demands of Chinese firms;
2. a large increase in the proportion of employed people volunteering (i.e. spending quality time, unpaid) with the poor and unemployed;
3. a sharp rise in the rate of theft (e.g. break-ins) of households and businesses.

                                                                                         [6 mark]

3. Suppose Britain’s formal departure from the European Union in 2020 results in some significant structural challenges to the British economy. The following hypothetical data show the state of the British economy from December 2020 to December 2021:

• the Consumer Price Index (CPI) falls from 110 to 100
• the underemployment rate rises from 4.7% to 10.1%
• real GDP per capita growth rate falls from 2.0% to -0.2%

Explain the phases of the business cycle the British economy is likely to be experiencing from December 2020 to December 2021. Provide specific reasons for your answer. Use a well-labelled AD/AS diagram to show the position of this economy in December 2021. Explain whether the British government should use expansionary or contractionary fiscal policy to move the economy back to the long run, full-employment GDP equilibrium. Draw the AD curve shift(s) associated with this policy on your diagram.

Copper and zinc work equally well as a chemical catalyst to mitigate pollution created in the production of lithium batteries. However, copper is currently 10% more expensive than zinc. And so, zinc is the current preferred material. The following diagrams represent the copper, zinc, and lithium battery markets.

However, some recent advances in pharmaceutical research have substantially increased demand for zinc in pharmaceutical manufacturing.

Using this example, explain how markets see to the most appropriate allocation of resources between competing uses. Limit your response to no more than 500 words. Be sure to include in your response the preceding diagrams, demonstrating the relevant change in each respective market. You may use Word drawing features or draw the diagrams, use your phone to capture them, and then insert them into your response. If you need help, ask. Your answer will be evaluated based on correctness, completeness, and clarity. Be attentive to your writing.
