Stackelberg

  • 2 firms with identical products
  • p=a-bQ
  • Leader (firm 1) sets output first and firm 2 follows and sets q2.
  • First mover advantage- can antcipate the follower's actions and can therefore manipulate the follower. 
  • Finding equillibrium: P=1000-4Q MC1=MC2=20
  • Anayse the followers decision, it observes q1 and chooses q2 to maximise profits:
  • -
  • Expand the brackets
  • -
  • Find the F.O.C and set equal to q2
  • -
  • Now analsye firm 1's decision 
  • -
  • Sub in q2

Price Competition

  • Products are indentical
  • First mover commits to a price greater than MC
  • The second mover will undercut his price and take the marker
  • Firms continually undercut eachother until P=MC
  • Equilibrium is P=MC
  • Identical to simultaneous game

Commitment

  • If leaders move is reversible, the threat it carriers is not credible and the leader's move loses all commitment power. 
  • Paradox of commitment: it is by limiting my own options that I can manage to influence the rival's course of actions in my interest.
  • How to commit?
    • Quantity Competition: proir reputation, investment in additonal capacity, place the stated output on the market...
    • Price Competition: "most-favoured customer clause", print catalogues ...
