Contestable markets

Question 1

features of contestable market

Answer 1

• face actual and potential competition
• entrants have free access to production techniques and tech
• no barriers to entry or exit
• good info
• constant comp entering market
• ‘hit and run’ comp for incumbent firms
• no sunk costs

Question 2

how does tech affect contestable markets

Answer 2

• tech decreases barriers to entry and exit

• contestable incumbent markets worried about new firms entering due to incentive of supernormal profit
  = they produce @ normal profit

Question 4

adv contestable market

Answer 4

• allocative efficiency= decrease P and increase choice
• productive efficiency= increase EoS= decrease costs and price
• low x-inefficiency= low waste
• high job creation as labour is a derived demand

Answer 6

• length of contestability= in LR use of anti-comp strategies won’t be contestable
• depends on role of tech= use of patents copyrights decrease contestability
• depends on levels of regulation
  = high reg decreases issues of cost cutting and anti-comp strategies to protect contestability
• depends on sunk cost levels e.g. advertising= barrier to contestability
