Studies show that young athletes are increasingly focusing

Question

1. The theory of comparative advantage predicts that athletes perform better when they specialize. Studies show that young athletes are increasingly focusing on a single sport. Do you think this is a good idea?
2. Yes, this is a good idea. According to the comparative advantage theory, unique products or firms producing better products at a lesser cost have comparative advantage over other firms. Likewise, if an athlete focuses on only a single sport, he will get better at it and will be at a comparatively advantageous position as compared to others who try out all the sports.
3. Are there any disadvantages to children and teenagers specializing and playing just a single sport?
