Monopolistic Competition in International Trade - Assumptions of The Model

Assumptions of The Model

  • 1. Each firm is presumed to be able differentiate its product from that of its rivals. Cars are a good example here; they are very different, yet in direct competition with each other. This means there will be some customer loyalty, which allows for some flexibility for the firm to move to a higher price. In other words, not all of a firm's customers would leave for other products if the firm raised its prices.
  • 2. This model dismisses the issue of interdependence when a firm sets its price. The firm will act as if it were a monopoly regarding the price it sets, not considering the potential responses from its competitors. The justification is that there are numerous firms in the market, so each receives only scant attention from the others.

    To me it was dilution. Where do these
    Innate assumptions come from?
    Philip Larkin (1922–1986)

    I had a wonderful job. I worked for a big model agency in Manhattan.... When I got on the subway to go to work, it was like traveling into another world. Oh, the shops were beautiful, we had Bergdorf’s, Bendel’s, Bonwit’s, DePinna. The women wore hats and gloves. Another world. At home, it was cooking, cleaning, taking care of the kids, going to PTA, Girl Scouts. But when I got into the office, everything was different, I was different.
    Estelle Shuster (b. c. 1923)
