The founding father of modern microeconomic theory analysis.
----
Term
What did Ernst Engel prove?

At least one good in a consumer's budget must be a normal good.

Where the budget constraint intersects with an indifference curve.
----
Term
How does one Algebraically Calculate Budget Constraints?
----
Definition
Total Income= ("Price of Good X" x "Amount of Good X Purchased") + ("Price of Good Y" x "Amount of Good Y Purchased")

Term
What is Corner Equilibrium/Solution?
---
Definition
Consumer equilibrium (Utility Maximization) in which one of the goods is not consumed at all. The Utility maximization point is right where the (y-axis or x-axis depending on which good is not being consumed) touches the budget line.
