201 Indifference Curves & Budget Constraints

Congratulations! You have successfully completed chapter 1! I hope you found it a breeze and as we move on to slightly more advanced topics, you will definitely get a hang of it! So, keep it up, people!!!

To introduce Chapter 2: Consumer Theory and Individual choice, let me give you an illustration. We all love shopping, do we!? I know I do! So I’m walking around town and I enter 2 stores: D&G and L.V.. Thing is… I have a limited budget of $100000!!

I’m a fashion freak and I live on fashion, baby! But, how many of each brand am I going to buy??? How do I decide?? What makes me satisfied with my purchase at the end of the day? Why do I make certain choices?

That is what this video is about, understanding the basics of how individuals maximize the use of their monetary resources.

At the end of this video, you should be able to:

  • Draw and denote important points of the Budget constraint and the indifference curve.
  • Understand the concept of Real Income.
  • Explain what an Indifference Curve is.

Additional Notes:

  1. The budget equation is important in answering certain questions. I0 = Px0.Xo + Py0.Y0 , where I0 is Income in monetary terms, Px0/Py0 is the price of X/Y and X0/Y0 is the quantity of X/Y purchased at point A.

    I’ve been looking for economics videos like these for ages. I love how clearly you explain the most important points. Plus, the mind maps?! It’s almost too good to be true! 🙂

    Hi,

    Please could you advise what the formula is for the indifference curve (which is in yellow) @ 05:39?

    I find the yellow is very, very difficult to see on youtube.

    Thank you for the great videos, it is really helpful.

      Hello! My bad, I stopped using yellow after a few videos. You mean the wordings below the “consumer indifferent”?
