In order to achieve stable and rapid economic growth, it is crucial to have a diverse and competitive market with new innovative companies entering freely. Successful new entrants play a significant role in shaping the long-term performance of the economy. Simply having the threat of new companies entering the market is not enough for dynamic competition. A growing economy needs a continuous influx of optimistic new entrants, even though some may fail in the end. Financial innovations like junk bonds can help reduce barriers to entry, allowing both successful and unsuccessful companies to contribute to economic growth.
