    44:42 can anyone explain how efficient producers have higher producer surplus?

    • @DavidRotin
      @DavidRotin 8 місяців тому

      Because if they are efficient that means that they can produce the products for cheaper and that mean that compared to inefficient producer they would have a higher margin of profit due to efficient production.

    Is LR demand always more elastic than SR demand?

    • @kamilkadziolka4113
      @kamilkadziolka4113 3 роки тому

      I'm not an expert here, but I think when we consider demand for a whole market e.g. 'food industry' then demand will be inelastic in both cases as there's no real substitute, so I think there's few cases but in general demand in lr will be more elastic

    • @apnaustaad9818
      @apnaustaad9818 3 роки тому

      Depends on the good, where close substitutes are easily available SR demand will always be more elastic than LR.

  • @marybuford9591
    @marybuford9591 2 роки тому

    What if the demand remains the same but the supplier wants more money and charges more? Will people buy less gas and hell stagnate so he reduces his supply and cost goes up etc. He'll reach equilibrium again when only a few consumers buy at a very high rate. He doesn't really care because he's making more money for less work. That's how u make a third world huh? There is a philosophy behind a good market.
