  • Input-output isoquant is a curve that shows all the combinations of inputs that can produce a given level of output. It was developed by Wassily Leontief.
  • CES production function is a type of production function that allows for substitution between different factors of production. It was developed by Charles Cobb and Paul Douglas.
  • Duopoly model is a model of market competition in which there are only two firms. It was developed by Augustin Cournot.
  • Kinked demand curve is a type of demand curve that is kinked at the current price. It was developed by Paul Sweezy.

Here are some additional details about each of the concepts:

  • Input-output isoquant is a curve that shows all the combinations of inputs that can produce a given level of output. It is a useful tool for understanding how firms make production decisions.
  • CES production function is a type of production function that allows for substitution between different factors of production. This is important because it allows firms to be more efficient in their use of resources.
  • Duopoly model is a model of market competition in which there are only two firms. This is a useful model for understanding how firms interact with each other in a market.
  • Kinked demand curve is a type of demand curve that is kinked at the current price. This is a useful model for understanding how firms set prices in a market.
