    I have SO much trouble in my economics class and couldn't find the loss because I didn't know you had to subtract the base. Thanks so much!

    My goodness thank you for this. I have a eco class every morning from 10:45AM-12PM on zoom where attendance isn't taken and my professor just records the class and posts it online. But I don't watch because I'm just too lazy. Your videos have been really helpful for a lazy dude like me.

    Your explanation regarding the tax situation (: If MC’ is our true marginal cost, then deadweight loss exists, because we want to be here (pointing at your new equilibrium) instead of here (pointing at your old equilibrium))sounds a bit misleading to me.
    Although you were right that taxation generates a deadweight loss, your description of the desired equilibrium is incorrect. Tax causes the supply curve to shift toward ( S’=MC’) and thus creates your new equilibrium. Your new equilibrium is where “we are” after taxation, whereas the desired equilibrium point (the allocatively efficient point) is the old one. In other words, the new equilibrium price and quantity are inefficient. (note that this differs from the process of solving the impact of externality on market outcomes.)
    3:22: No need for correction. Price after tax: 6; price before tax: 4.

    4:29 You’re wrong at this part.Because we’re doing calculation on our triangle. So that’s why our base is 2 and height is 1.
    But still it’s a really good video though Thnks :))

  • @Marco-mv1fc
    @Marco-mv1fc 6 ปีที่แล้ว +1

    might be a stupid question, but isn't the area of a triangle 1/2*base*perpendicular height meaning that the triangle should include a 90' angle? or does this not apply to calculating deadweight loss?

    • @FreeEconHelp
      @FreeEconHelp  6 ปีที่แล้ว +1

      The equation applies to all triangles.
      You may be able to demonstrate this to yourself by drawing a rectangle around any triangle and then filling in the void that is left in the rectangle (eg. area not covered by the triangle) to see that it fills exactly half of the newly drawn rectangle. For example: jeremykun.files.wordpress.com/2011/06/triangle1.png?w=596&h=302

    How do you know the third point is exactly at 4$?... Like I have these datas, what is the DWL: Qd=1200-2p, Qs=p-300, what is the DWL after 15 unit of tax? P=500, Q=200, P*=505, Q*=190, but there is no third P to be able to calculate the triangle's size...

    • @FreeEconHelp
      @FreeEconHelp  6 ปีที่แล้ว

      To solve this you need to add the tax to the appropriate function. It would be easiest to solve for the inverse demand (or supply) function and then add the tax to the function. EG. P=600-1/2Qd-15 (because the tax is fifteen and they are willing to pay 15 less for any given Qd). Alternatively, you can add the tax to the Qd function by adding it within the price: eg. Qd=1200-2(p+15).

    Deadweight loss is the loss in consumer and producer surplus. So how is deadweight loss represented in right side for negative externalities? There's no consumer or producer surplus

  • @stefancz4084
    @stefancz4084 10 ปีที่แล้ว +6

    isn't it the base that is 2 and the height that is one ? i mean it's the same result but it can be very bad to teach someone this.

    • @FreeEconHelp
      @FreeEconHelp  10 ปีที่แล้ว

      In this example, the height is 2 and the base is one (6-4) and (5-4) respectively, it's possible you learned it differently some where else.
