I know this is really not related to our chapter. However, if we think about how South Korea will do to protect their cow business, we can realize that it is related to our chapter. South Korean worry about mad cow disease. However, every other country people may think if South Korean didn't buy American beef, that is no problem. But, the American beef is really cheeper than Korean beef. Also, they know the American cow has mad cow disease and this is really harm to human. If the American beef is imported to Korea, most restaurant would use American cow because it is really cheep. Also, some restaurant fake to Korean. Every people couldn't eat food only their home. Therefore, they ban about American cow. In this case, what the South Korean government should do? There are two ways. The first way is that they take some excise tax to American beef. The other way is that they imposes a nonbinding price floor to Korean beef. The ways can protect Korean beef because customer want to buy more cheeper product.
