(a) How is the concept of concentration in the United States affected by the presence of foreign firms (not foreign firms that have factories or offices in the United States, but foreign firms that produce in their home countries and then export to the United States and are not included in the measures of C4 and HHI). Do these foreign firms tend to increase or reduce the degree of concentration in U.S. industry? Please explain.

(b) An industry consists of three firms with equal annual sales. What is the industry's HHI and C4? Please show your calculations.

Natsumi is a citizen and resident of Japan. She has a full-time job in Japan and has lived there with her family for the past 20 years. In 2017, Natsumi came to the United States on business and stayed for 240 days. She came to the United States again on business in 2018 and stayed for 120 days. In 2019 she came back to the United States on business and stayed for 120 days. Does Natsumi meet the U.S. statutory definition of a resident alien in 2019 under the substantial presence test?

The following data were drawn from the Latin American Migration Project, a collaborative research effort based at Princeton University and the University of Guadalajara, supported by the National Institute of Child Health and Human Development (NICHD) (http://lamp.opr.princeton.edu). A random sample of respondents was drawn from three Latin American countries: Nicaragua, Guatemala, and Costa Rica. The variable if interest is the duration (in months) of stay in the United States during respondents’ first migration to the United States.

Nicaragua: 4, 6, 6, 6, 12, 36, 36, 36, 36, 60, 72, 78, 96, 120, 126, 156, 162, 162, 186, 540 Guatemala: 1, 1, 12, 24, 24, 24, 36, 36, 42, 60, 78, 84, 102, 102, 102, 102,132, 144 Costa Rica: 12, 12, 12, 12, 14, 15, 15, 18, 18, 24, 36, 48, 66, 120, 150, 150, 174, 282, 288

a) What is the level of measurement of duration of stay during first U.S. migration?

b) Calculate the value of the mode for each country.

c) How does the mode for Guatemala compare to that of Costa Rica?

d) In light of your answer to c), perhaps one explanation is that respondents from Latin American countries that are closer to the United States have a higher modal duration of stay in the United States during their first U.S. migration than respondents from Latin American countries that are further away from the United States. Does the evidence from Nicaragua support this idea? (Hint: examine a map of Latin America to see whether you would expect the mode for Nicaragua to be greater than or less than that for Costa Rica and Guatemala.)

e) Given your results from b), you are interested in extending this idea to the value of the median. Which country would you expect to have the highest median duration of stay in the United States during first U.S. migration?

f) Calculate the value of the median for each country. Which of the three countries above in fact has the highest median value? Does this support your idea that respondents from Latin American countries that are closer to the United States have a higher median duration of stay in the United States during their first U.S. migration than respondents from Latin American countries that are further away from the United States? Explain.

g) Notice that both Guatemala and Costa Rica have some very low and very high values. Which measure of central tendency is most susceptible to such extreme values?

h) Given your results from b) and f), you are interested in extending the idea that respondents from Latin American countries that are closer to the United States have a higher mean duration of stay in the United States during their first U.S. migration than respondents from Latin American countries that are further away from the United States. Which country would you expect to have the lowest mean duration of stay during first U.S. migration?

i) Calculate the value of the mean for each country. Which of the three countries above in fact has the lowest mean duration? Does this support your idea that respondents from Latin American countries that are closer to the United States have a higher mean duration of stay in the United States during their first U.S. migration than respondents from Latin American countries that are further away from the United States? Explain.

j) For each country, identify the direction in which (if any) the distribution is skewed? Provide specific evidence using your answers from the previous questions.

What is the sanctions process in the United States, the United Nations, in the European Union?

• How would you suggest the United States reduce the cost of medical health insurance?

• Why do you think the United States has not adopted the approach to health care as Canada, France, and much of the developed world?

Several candidates running for President of United States are promoting and supporting Health Care for All. Should the United States join other countries that have Universal Health Insurance? If so, why? if not, why not? Minimum of 500 words.
