Hufbrauer, G. “The Payoff from Globalization” (https://www.piie.com/commentary/op-eds/payoff-globalization)

1. Is trade a zero sum game, i.e. are there any losers to increased liberalization? Why or why not?
   Wolak, “Our Comparative Advantage” (https://www.nytimes.com/roomfordebate/2011/01/18/can-the-us-compete-with-china-on-green-tech/ourcomparative-advantage)
2. Why do we see more innovation and development in the U.S? Why might this lead to an undesired outcome?
   Dizikes, “Economists find evidence for famous hypothesis of ‘comparative advantage’” (https://news.mit.edu/2012/confirming-ricardo-0620)
3. Why is it difficult to prove comparative advantage?
4. Are there ways to "find" comparative advantage? (You may need to be a bit creative here).
   Prestowitz, “The Losses of Trade” https://www.huffpost.com/entry/the-losses-of-trade_b_985820
5. Why are the costs more substantial than what is normally assumed under conventional trade theory? (Be sure to have a look at what Prestowitz states).
