A consumer allocates all of her income between two goods, food and clothing, with the quantity of food consumed captured by the variable F while that of clothing by the variable C. The consumer has usual strictly convex preferences between the two goods. Assume that food is an inferior good and it is kept on the horizontal axis.

Suppose that the consumer’s income remains unchanged but prices of both of these goods change.

• Scenario A: Assume that both prices fall with price of food falling by a higher percentage relative to clothing.

(a) State the impact of the price changes you are required to examine on the relative price of food.

(b) Determine whether clothing should be treated as a normal or inferior good and explain your answer.

(c) Now proceed with doing a geometric analysis to portray one case that is logically consistent with the price change scenario you need to examine as specified in (a). In doing so, illustrate and explain how the consumer’s optimal bundle might change in response to the cumulative impact of these price changes.

(d) Comment on whether the direction of total change in optimal quantities of food and clothing that you have shown in your diagram for part (c) are the only logically consistent possibilities. Or, is it also possible that changes could also be in the opposite direction? Explain your answer. You do not need to do additional diagrammatic analysis to answer this part.

Conch Republic spent $750,000 to develop a prototype for a new smart phone that has all the features of the existing one but adds new features such as wifi tethering. The company has spent a further $200,000 for a marketing study to determine the expected sales figures for the new smart phone. Conch Republic can manufacture the new smart phone for $205 each in variable costs. Fixed costs for the operation are estimated to run $5.1 million per year. The estimated sales volume is 64,000, 106,000, 87,000, 78,000, and 54,000 per year for the next five years, respectively. The unit price of the new smart phone will be $485. The necessary equipment can be purchased for $34.5 million and will be depreciated on a seven-year MACRS schedule. It is believed the value of the equipment in five years will be $5.5 million. Net working capital for the smart phones will be 20 percent of sales and will occur with the timing of the cash flows for the year (i.e., there is no initial out-lay for NWC). Changes in NWC will thus first occur in Year 1 with the first year's sales. Conch Republic has a 35 percent corporate tax rate and a required return of 12 percent. Shelly has asked Jay to prepare a report that answers the following questions:

e. How sensitive is the NPV to changes in the price of the new smart phone?

f. How sensitive is the NPV to changes in the quantity sold?

g. Should Conch Republic produce the new smart phone?

This patient’s ependymoma was located in the tapered caudal end of the spinal cord, which is supplied by branches of the aorta and spinal arteries. Ependymomas in this region are particularly vulnerable to vessel damage due to higher mobility and vascularization, and movement can lead to vessel rupture and hemorrhage, as occurs in this case. In this case, the patient suffered from a sudden onset of symptoms, presumably following hemorrhage. Answer the following questions regarding the loss of motor and sensory function observed.

Justify the patient’s sudden onset of lower limb paralysis by answering the following questions:

a. Using words and/or drawings, be sure to describe the structure of the corticospinal pathway. Identify the location of the upper and lower somatic motor neurons, decussation, and white matter tracts in the spinal cord. Then, describe how the patient’s ependymoma and subsequent hemorrhage impacted excitability of somatic neurons in this pathway.

b. Justify the patient’s paralysis in both lower limbs. Describe how changes in excitability in lower motor neurons leads to changes in excitability in a skeletal muscle fiber (cell). In your answer, be sure to briefly describe the structure and function of the neuromuscular junction (NMJ), identifying any membranebound proteins and the sequence of events required for skeletal muscle excitation and subsequent force generation. State how ependymoma hemorrhage changes graded and action potentials in a skeletal muscle fiber (cell), the concentration of intracellular calcium, and cross-bridge formation in the muscle.

Multiple choice: Consider the following scenario: Changing conditions on an island lead to the death of all plants producing medium sized seeds.

Consider an economy in which the government employs teachers to provide education services to the public which are funded entirely by taxes. These government employees (i.e. doctors) earn salaries for this work. Assume that a pandemic starts which causes many parents not to send their children to school. Assume that enrollment drops by 50%. The number of teachers as well as their pay (i.e. salaries) stay the same during the same period. (a) Using the expenditure approach, determine how the GDP changes over time? Explain. 1 (b) Now suppose that all education services are provided by the private sector. Private schools charge each student a fee or tuition. Assume that the same pandemic hits, and half of parents choose not to send their children to school. The number of teachers as well as their pay (i.e. salaries) stay the same during the same period. Using the expenditure approach, determine how the GDP changes over time? Explain, and contrast your answer with the part (1a). (c) Consider the following additional information. Children who are not sent to school by their parents receive education from parents at home, i.e. they get homeschooled. Assume that the quality of home-schooling is as high as that of regular schools. For simplicity, assume that home-schooling does not imply a time cost to parents. What are the welfare implications of this for both (1a) and (1b)? Does the change in GDP reflect the changes in welfare accurately? Explain.
