Figures A, B, and C are taken from a paper by Chad Bown "The Pattern of Antidumping and Other Types of Contingent Protection" (World Bank, PREM Notes No. 144, October 21, 2009), and updated from Chad Brown, 2012, "Global Antidumping Database," available at econ.worldbank.org/ttbd/

a. Figure A shows the number of newly initiated trade remedy investigations, including safeguard (SF), China safeguard (CSF), antidumping (AD), and countervailing duty (CVD) (a countervailing duty is used when foreign firms receive a subsidy from their government, and then the CVD prevents them from charging lower prices in the importing country). Each bar shows the number of new cases in each quarter of the year (Q1, Q2, etc.) for 2007 through Q1 of 2012. The number of cases is graphed separately for developing countries and developed countries. What does this graph tell us about what has happened to the number of such cases since 2007? What might have caused this pattern?
b. Figure B shows the number of safeguard (SF) tariff initiations by WTO members. Since 1995, what three years saw the largest numbers of safeguards? What might explain these increases?
c. According to Figure B, year 2002 had the most safeguards actions by WTO members. How many actions were started that year, and what U.S. safeguard case that year was discussed in this chapter?
d. Figure C shows the number of newly initiated antidumping (AD) investigations, for quarters of the year from 2007 through Q1 of 2012. Compare the number of cases in this graph with Figure A, which included safeguard (SF), China safeguard (CSF), antidumping (AD), and countervailing duty (CVD). What can you conclude about the total number of SF, CSF, and CVD cases as compared to the number of AD cases?
