1. After the reopening of borders with mainland China following the COVID-19 lockdown, residents
living near the border now have the option to shop for food on either side. In Hong Kong, the cost
of food is at its listed price, while across the border in mainland China, the price is only half that
of Hong Kong's. A recent report indicates a decline in food sales in Hong Kong post-reopening.
**
Diagrams need not be to scale; Focus on accurately representing the relevant concepts
and relationships rather than the exact proportions.
(a) Using a diagram, explain why Hong Kong's food sales might have dropped after the border
reopening. Assume that consumers are indifferent between purchasing food in Hong Kong or
mainland China, and therefore, their indifference curves have a slope of one like below.
Additionally, consider that there are no transport costs and the daily food budget for consumers
is identical whether they shop in Hong Kong or mainland China. I

2. Health Food Company is a well-known global brand that specializes in healthy and organic food
products. One of their main products is organic chicken, which they source from small farmers
in the area. Health Food Company is the sole buyer of organic chicken in the market.
(a) In the context of the organic chicken industry, what type of market structure is Health Food
Company operating in?
(b) Using a diagram, explain how the identified market structure affects the input pricing and
output decisions of Health Food Company. Specifically, include the relevant curves and
any key points such as the profit-maximizing price and quantity. ()
(c) How can encouraging small chicken farmers to form bargaining associations help improve
their trade terms? Explain how this works by drawing on the graph in answer (b) to
illustrate your answer.
2. Suppose that a farmer has two ways to produce his crop. He can use a low-polluting
technology with the marginal cost curve MCL or a high polluting technology with the
marginal cost curve MCH. If the farmer uses the high-polluting technology, for each unit of
quantity produced, one unit of pollution is also produced. Pollution causes pollution
damages that are valued at $E per unit. The good produced can be sold in the market for $P
per unit.

If you could please write down your steps so I can see how it's done please.arrow_forwardSuppose that a random sample of 216 twenty-year-old men is selected from a population and that their heights and weights are recorded. A regression of weight on height yields Weight = (-107.3628) + 4.2552 x Height, R2 = 0.875, SER = 11.0160 (2.3220) (0.3348) where Weight is measured in pounds and Height is measured in inches. A man has a late growth spurt and grows 1.6200 inches over the course of a year. Construct a confidence interval of 90% for the person's weight gain. The 90% confidence interval for the person's weight gain is ( ☐ ☐) (in pounds). (Round your responses to two decimal places.)arrow_forwardSuppose that (Y, X) satisfy the assumptions specified here. A random sample of n = 498 is drawn and yields Ŷ= 6.47 + 5.66X, R2 = 0.83, SER = 5.3 (3.7) (3.4) Where the numbers in parentheses are the standard errors of the estimated coefficients B₁ = 6.47 and B₁ = 5.66 respectively.

It sent out proxies to its stockholders on March 15 and asked stockholders who plan to attend the meeting to respond. To plan for a sufficient number of information packages to be distributed at the meeting, as well as for refreshments to be served, the company has asked you to forecast the number of attending stockholders. By April 15, 378 stockholders have expressed their intention to attend. You have available the following data for the last 6 years for total attendance at the stockholder meeting and the number of positive responses as of April 15: Year Positive Responses Attendance 2007 322 520 2008 301 550 2009 398 570 2010 421 600 2011 357 570 2012 452 650 1.
