Some Key Terms For Ch 2 of the SG
So I will list the words that I didn't grasp fully or was confused about in certain contexts (e.g. I knew what these words meant in some context but not in others)
Source: HERE
1. Utility: measure of relative satisfaction from or desirability of consumption of various good & services. In plain English = A scale of (probably on a graph) of how much satisfaction we get from a goods & services (product)
2. Neoclassical economics: Old school economic concepts.
3. Rationality: An old school econ, oops, neoclassical economics concept. It is precisely defined in terms of imputed utility-maximizing behavior under economic constraints.
Plain English: people getting the maximum satisfaction out of their limited resources (remember the PPF!!! Always go back to the PPF), in other words they are on a point at the PPF, not under. If they are under the graphed line, then it is irrational behaviour.
4. Indifference Curve: plots the combination of commodities that an individual or a society requires to maintain a given level of satisfaction.
Plain English: Please leave a comment, on how to put this in plain English, LOL, cuz I don't know!
5. Ordinal utility: states that while the utility of a particular good and service cannot be measured using an objective scale, a consumer is capable of ranking different alternatives available.
Plain English: Basically it's how a customer rates how much one product over the other (remember the ~ indifferent to, and > prefers) using the scale system (like 1 to 5 or 1 to 10 or 4 stars, etc)
6. Cardinal utility: The magnitude of utility differences is treated as an ethically or behaviorally significant quantity. (Remember the SG, pg 69, Example 2)
Plain English: How much more does someone like A over B over C, etc.
7. Transitive: Noting a relation in which one element in relation to a second element and the second in relation to a third element implies the first element is in relation to the third element, as the relation “less than or equal to.”
Plain English: (Personally this word drove me the craziest as to what it meant). If there's product A & B, and if you prefer one over the other, then it's transitive, so you need 2 or more items for basis of comparison.
8. Complete: Of or pertaining to a set in which every fundamental sequence converges to an element of the set.
Plain English: (This also drove me crazy), it basically means when the comparisons are done, e.g. A > B > C, it is transitive because you're comparing and it's complete because you finished/concluded the comparison :)
I hope this was helpful, if you have any questions or see any mistakes please feel free to leave a comment and I'll correct them or if you have a simpler explanation, please leave a comment.

Study Notes from Last Weekend
2. Rationality - This is a neo-classical economic concept (modern day vernacular would be Optimization or Utility), in a nutshell means Theory of Individual Behaviour and Motivation (Supply & Demand), so we can say this is a Micro Economic Concept, so for those of you not reading the main text, just read the chapter in other texts that talk about individual/household choices.
The word CONSTRAINT, once again shows up here, remember it's a fancy way of saying "LIMIT" in Economics. That means we could only (given there are 2 products) produce so many combinations of salads or pastas. IF it's our allowance/paycheck, then we can only buy so many combinations of pizza or sushi or pizza and beer :)
Rational in Economics term does not mean "NORMAL" and irrational in Economics does not mean "NOT NORMAL." In Economics, it just means we're not producing/spending at a point on the graph (Irrational) or we are producing/spending at a point on the graph (rational).
Page 63: Here the ability to produce increased, this can be because the wife hit him in the head or we just learned how to make salads & pasta faster (technological efficiency/improvement). When it comes to the pizza/sushi, pizza/beer combo, then it would mean we won the lottery, got a raise or changed jobs and got a bigger paycheck. So our individual rationality (the graph/curve) would change (see page 64 of the SG). When you become confused about this graph, just go back to the PPF, when production is not occurring at a point on the line of the graph, then you're not at maximum utilitzation, and if you're not at the point of the line of the individual rationality graph then you're being irrational.
Please refer to page 63: Inconsistency - This in economics term is not when an athlete has a great game one day and tanks it the next. This refers to our changes in taste or preferences :)
Page 65 - Preferences - This is to measure ranking of one product over another, not quantifying her satisfaction/pleasure. To express:
A > B = A is preferred to B
A ~ B = indifferent between A & B
Let's clear the misunderstanding of the word indifference here. It does not necessarily mean that you're indifferent (in the dictionary sense), it would mean that you don't have a preference of one item over another, or you like both equally the same.
e.g.
iPhone > all other cell phones = this means I prefer the iPhone over all other cell phones (unfortunately it's unavailable in South Korea)
Brand A Cell Phone ~ Brand B Cell Phone = I have no preference over any other brands of cell phones.
Let's rank this:
iPhone > Brand A Cell ~ Brand B Cell
I prefer the iPhone over Brand A Cell Phones & Brand B Cell Phones, but am indifferent to Brand A Cell between Brand B Cell.
Hope this was helpful.
One final note, only real numbers can be expressed here (good news for us at least mathematically)

Production Possibility Frontier (PPF) aka Transformation Curve
Wednesday, October 15, 2008
Terms we should remember
Page 38.
1. Modelling
2. logical truth
3. Production Possibility Frontier (PPF) aka Transformation Curve.
4. means of production
5. constrained
6. technology (in economic terms)
Page 40:
Remember the formula 1/2Y + X is equal to or less than 100
Page 42:
1. Productive efficiency
2. productive efficient
3. Opportunity cost
Page 43
1. Opportunity cost formula
2. binding
3. Inefficient allocations
3. best alternative production
Pa 50:
1. average
2. marginal opportunity cost
3. margin
4. marginal.
I'm not a big proponent of memorization method of studying BUT if we don't know what these words mean and understand the concept of them we'll never get going in our studies in economics. So when we talk to each other let us speak in this language to one another because if you use a word in everyday language then you'll have it memorized forever. Just like when I learned Japanese & Korean & Spanish. Talk this language to your friends, b/f, g/f family, etc. :)
Great Helpful Site
Chapter 1 of the study guide talks about the PPF, so for a great explanation, click HERE
A little note on the opportunity cost formula. Remember Rise over run in math? Change in Y over Change in X??? Think of it as the same but without the "Change in", so it would be
Y/X
Y= What we had to give up
X = What we got in return
So the opportunity cost of a Unit of X = Y/X

Stanford's Entrepreneurship Corner: David Rothkopf Part 5
If the people who set the prices are the same people who set the production levels, then it's not really a market, and true supply and demand are a farce. David Rothkopf, author of Superclass: The Global Power Elite and the World They are Making, says that Europe is leading the planet in green energy technology thanks to government subsidies, including biofuels and wind energy. Rothkopf is optimistic that the US will eventually adopt these policies toward energy, though our current system is corrupted by nearsighted, pure financial interest.

If we don't recognize that the unequal distribution of wealth is unsustainable, then, perhaps, says author David Rothkopf, more sinister political tensions and divisions will ensue. He advocates that the planet needs to reflect upon why we have one set of rules for our geographic community, and a different set of rules for institutions, among them the for-profit sector. Only when we hold the powerful players in economics responsible for contributing to the welfare of our community as we would a neighbor, says Rothkopf, will the interests of the globe at large become balanced.
Stanford's Entrepreneurship Corner: David Rothkopf Part 3
Sheer brainpower, strength in numbers, and good old fashioned networking is how the nature of world influence is established. Skewed and disproportionate, modern power structures that regulate global problems happen only when the elite meet, says author David Rothkopf. And decisions made based on these meetings often do not adequately represent the people or the interests that they are meant to serve.
Stanford's Entrepreneurship Corner: David Rothkopf Part 2
We can't legislate against historical trends in the global age, but we can look more closely at the well-networked superclass - those who have broad influence across international borders on a regular basis. The Superclass has money, power, and influence - but it's woefully short on ethics in the global interest. Author David Rothkopf describes this influential core of the global power structure and stresses that economic prosperity can't be the only metric of a civilization's success.
Stanford's Entrepreneurship Corner: David Rothkopf Part 1
Just twenty percent of the members in any group or social system own eighty percent of the assets, indicative that scale indicates a growing concentration of power. The top 2,000 companies employ and influences a million people in the modern world, says author David Rothkopf. With cross-ownership and networking in all circles - business, military, religion, and the Internet among them - a few succeed, but the majority of participants within any given system are marginal.

Unit information sheets
My theory & speculation on what will be on the test based on the Info Sheet:
General Equilibrium - the IS-LM model.
Prices, Inflation, & Unemployment - Aggregate Demand (AD) in the price output plane, the problems with deriving Aggregate Supply (AS); the Keynsian & the classical AS.
The Phillips Curve
Macro - Aggregation
Read the rest of the Info sheet, a very big clue on at least which graphs, math formulas to remember :)
