title: Barriers to entry
text: In economics, barriers to entry (also known as barrier to entry) refers to the things that makes it difficult for a firm or a person to enter a market. These are called obstacles and makes it harder for a firm or a person to enter a market. Examples of barriers to entry include government regulation for firms and the need for a certain level of education for a person.
  
  Barriers to entry helps to protect existing firms in the market from new firms entering a market and thus reduces competition in the market, which causes prices to be higher than what is accepted by society. Monopolies and market power is thus formed due to the existence of barriers to entry.
