Because patterns of comparative advantage can change over time, some producers may find their competitiveness diminishing, especially those who fall behind in research and development, technology, and equipment (the same idea applies to individuals). Therefore, producers are under continuous pressure to "reinvest themselves". No producer can maintain the world's lowest-cost producer forever, and producers need to hone their skills to be more competitive in other profitable areas, as comparative advantages change over time. Please give a detailed example of a company (or an individual) that lost its comparative advantage over time (and may have gone out of business after being the best), or an example of a company that is working hard to reinvent itself to remain highly competitive. What is your advice for a company (or an individual) to remain successful?
