Topic: Abstraction <=PAGE BACK | PAGE NEXT=>

Economic theories are abstractions of the real world.

Three ways to abstract:
  • Words. The earliest human method of abstraction was to represent objects with words. Words also represent ideas. But words can have different meanings.
  • Graphs. Pictures, especially graphical pictures. Many economic theories are abstractly represented with graphs. A picture or graph can be less confusing that words.
  • Equations. Graphs are two-dimensional pictures of mathematical equations. Economic theories are often abstractly represented by equations. Equations can represent relationships between three or more things, like that for X, Y and Z:
Y = 3 + 2X - 4Z

LOGROLLING

The trading of votes to ensure a favorable outcome for two or more separate decisions. Logrolling occurs when each of two people agree to vote for the other's project to ensure that both are passed. A votes for B and B votes for A. Logrolling is commonly used when neither decision is able to obtain the necessary majority of the votes needed for passage on their own accord. Explicit logrolling is when each of two voters agree to cast separate votes for two separate programs. Implicit logrolling is when two separate programs or policies are combined into a single package, which is then subject to a single vote. Logrolling can generate either an efficient or an inefficient allocation of resources, meaning that efficiency is irrelevant to the logrolling process.

This isn't me! What am I?

The standard "debt" notation I.O.U. does not mean "I owe you," but actually stands for "I owe unto..."
