INCOME of buyers -normal goods v. inferior goods -as income increases the demand for normal goods INCREASES; as income increases, the demand for inferior goods DECREASES. 3. TASTE/PREFERENCES of consumers; people want different things which can increase/decrease demand- if they really want something it will increase 4. EXPECTATIONS; when consumers expect price changes of certain goods; expect price to increase, demand will go UP before the spike (get it quick!) 5. RELATED goods: substitutes/complementary goods 6.

REGULATION - MORE regulation = LESS supply 5. EXPECTATIONS - HIGHER expectations = MORE supply 6. TAXES & SUBSIDIES - HIGHER taxes = LESS supply (bc it costs more to produce) - MORE subsidies = MORE supply (bc more gov assistance so it costs less for them to produce..

No mention of government 2. No interaction between firms 3. No mention of international sector 4. ALL EXPENDITURE = ALL INCOME10 examples of uncommon sense in economics1. Wars are bad for the economy and reduce living standards 2. Competition can direct self-interest toward broader interest, and may promote overall goods 3. Prices are information 4. Our real income is determined from labor productivity, not credentials (example, a college degree does not guarantee a good income) 5. we pay taxes according to implicit bargaining power, not according to explicit tax laws. 6. Entrepreneurs in private businesses don't always face "correct" market incentives (under/overproduce) 7. Price controls and regulations often have unintended consequences. 8. small groups often have advantages over large groups 9. Economies need the financial sector, but it is also subject to recurring crises. 10. There are no quick/easy paths to wealthBroken Window Fallacyrelates to the idea that wars are bad for the economy-repairing damage does require a lot of work, but doesn't increase overall wealthEconomicsa studies how people perceive causal connections between scarce resources and alternative end uses for these resources.What do we mean by scarce resources/economic goods?Just about anything that isn't unlimited to people. Time is a scarce resource. Air is not. But scarce resources must be allocated, and economics studies how they are allocated (i.e. why we use diamonds for jewelry and not for something else maybe)The Planning Probleminability of many people to take advantage of the most advantageous means of settling the allocation problem. This happens when we don't really know the true causal connections scarce means and desired goods.Rationalitypeople try to identify causal connections between scarce means and their ends as best as possible.Buchanan-Becker approachok so these two guys applied econ to a bunch of social studies like marriage, family planning, crime, charity, etc.academic imperialismwhen economists take over topics studied and taught by political scientists, anthropologists, and sociologists.macroeconomicsfocus on trends in statistical aggregates of the economic systemmicroeconomicsfocuses on individual markets and organizationPositive issueswhat actually happens in economics, like facts and statistics. i.e "Some women choose to have abortions"normative economicswhat should happen in economics, like how things should work. i.e. "Women should not have abortions"Ad Populum Fallacythe idea that something is true because a majority believes it.Appeal to AuthoritySomething to avoid-it is when people believe someone simply because they have high credentials. It doesn't mean that person is correctThe Psychologist's Fallacybelief that one's own perception of one's own experiences is universally and objectively trueThe Historian's Fallacythe idea that a current belief is correct because it is modernThe Fallacies of belief include:Ad Populum Appeal to Authority Psychologist HistorianNirvana Fallacieswhen people use economic theory to imagine ideal systems, then criticize or reject actual economic institutions/systems because an imaginary system looks better includes the false dilemma, and the moralistic fallacyFalse dilemmathe idea that we can only choose between a real (imperfect) option and a superior imagined alternative.Moralistic fallacythinking that something is feasible because it is good. (i.e preventing auto fatalities is good, but we can't prevent all auto fatalities)Fallacy of compositionthinking that if something is true for one person, it must be true for the whole groupFallacy of divisionthinking that things that are good for groups are good for the individual.Post hoc fallacy"after this, therefore caused by this" aka believing that something was caused by something else because it came after it.Appeal to Emotionscience relies on logic, not pity, fear, humor, whateverloaded terminologywords that evoke strong emotionsopportunity coststhe expected value of whatever a person gives up in order to get what they want in the future.Laissez-Faire Economyan economic system with private ownership of industry, directed by entrepreneurs. The entrepreneurs are regulated by private competition in markets. Government officials protect property and settle disputes.Activist EconomyOpposes L-F Economy, where government officials activist government consists of public agencies that design and implement plans intended to override or change the economic results of rivalry in private marketsFalse dilemmawhat prices result in the most efficent use of scarce resources?prices that achieve a balance of everyones personal interests and get the most gains from trademarketssocial orders where people sell goods and serviceslow opportunity cost consumersome people have a high preference for one type of product and dont much like the alternatives (good customers) pg42Adam Smith's "The Invisible Hand" of marketsasserts that regulation by competition mechanism in L-F economics outweighs the activist economy. Basically, the markets are self-regulating and self correcting. It limits how entrepreneurs make profits, rivalry may guide entrepreneurs to "do the right things" demand influences supply, if demand for one good rises the suply of alternatives goes downThe Tragedy of the CommonsAristotle's contribution to econ, which says people have strong incentives to use and care for their own property, and strong incentives to use public property, but personal incentives to care for public property.losses from tradeequal the difference between the high end of the supply curve and the low end of the demand curve (look at pg 42)gains from tradea money price or exchange value that is below the personal use value of any consumer provides net gains to these consumersSmith-Hume theorythey thought price reflects the cost of labor/production to make a good (wrong, btw), and invisible hand drives progress. Marx would disagree on the progress bit. This other guy, Ricardo, liked the Smith-Hume theory, but saw that prices didn't always match production cost.private enterprisesorganizations within which people organize to achieve goals (make profit)high opportunity cost producerthey produce but have many other valuable opptions and therefore have highopportunity costs of production pg 42positive sum gamewhen both parties in a trade make out with gainsentrepreneurs surplusexcess of market price of over marginal costs, below the selling price of P*when do people get the most gains from trade?people get the most gains when the market is in equilibriumconsumers surplusexcess of use value, or wilingness to pay, below the demand curve and above the price pg 46reverse valuationmeans people trade goods in reverse order of valuation -

For example, candy bars are an elastic demand. If the price of candy is around $1, most people will buy the candy and it will be high in demand. However, if that same candy bar's price rose up to $4, most people would not buy the candy.inelastic demandPeople will buy goods with an inelastic demand no matter what the price is. A good example of this would be gas. People complain and complain about gas prices, yet they still buy it because they need it, even if it $3 a gallon. Another example would be life-saving medications. Even if they are expensive, people will still buy them or else they could possibly die.perfect markets-free entry /exit -perfect info -zero transaction costs -perfect defined property rightsmarket imperfections (normal market)-low entry/ exit barriers -optimal info -low transaction costs -imperfect property rightsmarket failure-high entry-exit barriers -no info -huge transaction costs -no property rightswhat does relative elasticity tell us?it tells us about bargaining power -inelastic side of market= more bargaining power(both supply and demand )transaction costscosts of negotiating and carrying out the trading process ( never 0) -serve as impediments from gains from tradesearch costdevoting time to search (opportunity cost ) - spending money on info - longer search = higher costrational ignorance- knowing that you don't need to know certain things (everything)optimal information- the info needed for a market (no more no less)aysemetric information- where some people have private info that is pertinent to decisions made by others (each side plays up strengths and down weaknesses )how to achieve better info and avoid losses from trade- incentive compatibility -search goodincentive compatabilityincentives line up to bring about or signal (pertinent ) private info credibly - so incentivise the reveal of private info to enable better trades to happen thereby making markets work bettersearch good- a good in which characteristics of which can be learned in advance so we can be reasonably confident in assessment of marginal benefits -can't learn somethingscreedence goodeven with experience you cant know if its goodknowledge compatabilityexists when person forms plans that contain all pertinent info from the plans of others - ability to use all goods best - prices convey info - info exchanged efficiently -experience, search, compatible schemes -prices all info that enable industries to be coordinated from consumersplan alignmentwhen market prices are close to equilibrium they are sending info to sellers and buyers - prices convey info about supply side and info to supply sidegame theory/prisoners dilemmadescribe how players interact based on their informationNash EquilibriumWhere each player in a game has incentive to play strategy that is optimal given the strategy played by other players.

How does time affect elasticity?The more elastic, the more bargaining power. The more time, the more elasticWhat determines price. Labor input, or marginal cost and benefit and opportunity cost?marginal cost and benefit plus opportunity cost, because labor is a sunk cost. As marginal cost is low, ATC is decreasing, so profits likely are increasing and the price is moving toward equilibrium. As marginal cost increases, ATC increases and price moves away from equilibrium.ScarcityThe situation where our unlimited wants exceed the limited resources available to meet those wants. Consequently, whenever we make the decision to use our limited/scarce resources in one way, we cannot use them in their next-best way (i.e. opportunity cost). Hence, we need to try to develop ways of using the limited resources we have in the best way possible (i.e. we need to figure out how to make the best choices!).EconomicsThe study of how we (individuals and societies) attempt to best meet unlimited wants with limited/scarce resources, which have alternative uses.Resources/Factors of ProductionsThe inputs (land, labor, capital, entrepreneurship) used to make goods and services.LandAll natural resources.LaborHuman talents/resources used in the production process.CapitalSomething made so that it can make something else. In this class, capital is physical capital and is NOT referring to money, stocks, bonds, etc.EntrepreneurshipManagerial and risk-taking talent that joins all the other inputs together.Opportunity CostThe next-best alternative sacrificed when a choice is made.Pure CapitalismAn economic system (based on the ideas of Adam Smith from his book The Wealth of Nations 1776) in which buyers and sellers, operating in "free markets," operate with little government intervention ("laissez faire").Pure Command/Control EconomyAn economy in which government controls virtually all allocation, production, and distribution. The government (also called the "state") owns the capital and plans the production levels and production and distribution methods for most goods and services.Traditional EconomyAn economy in which economic activities today occur based on the way things have been done in the past.Mixed EconomyAn economy which combines (to varying degrees) reliance on markets, tradition, and government involvement to deal with the problem of scarcity of resources.Technical EfficiencyProducing the maximum possible output from our currently available inputs.Economic EfficiencyProducing the maximum possible output from our currently available inputs and having that output match the desires of the society. While there are many ways to be technically efficient, there is only ONE way to achieve this type of efficiency. In capitalist economies, prices/markets determine what the society "desires," while in command/control economies, the government makes those choices.EquityThis term means "fairness." The idea of fairness depends on the type of economic system in place. In capitalism, fairness means rewarding people based on what they produce that is of value in the market. In command/control economies, fairness is based on the Marxian concept of meeting each person's basic needs, irrespective of what each person produces.John RawlsPhilosopher whose "original position" thought experiment challenges us to define what "equity" would look like. Specifically, the "original position" experiment asks us to consider what type of economic system we would establish if we hadn't yet been born but were going to be born, with equal odds of being born into the richest family in the society or the poorest family in the society.Adam SmithAuthor of The Wealth of Nations (1776), in which he sets out the characteristics of a purely capitalistic economic system - one that relies on competition, private property rights, and free markets (prices), with very minimal role for the government ("laissez-faire"). This author argues that when each person pursues their own "self-interest," their choices end up maximizing the benefits for the overall society (via the "invisible hand" of the marketplace).Karl MarxAuthor of Das Kapital (1867+) and The Communist Manifesto (1848). This man believed that capitalism would destroy itself because of the conflict/struggle between the oppressed working class (the "proletariat") and oppressive capitalist owners (the "bourgeoisie"), leading to revolution and an overthrow of the capitalist system. This man's ideas inspired individuals such as Vladimir Lenin (1st Communist leader of the Soviet Union) and others to pursue government control of the economy and a "communal" view of economic life.Production Possibilities Frontier (PPF)A graph illustrating the maximum output combinations an economy could possibly produce, given the existing state of technology and currently available quantity and quality of inputs.Law of Increasing Opportunity CostsAs we produce more and more of one good, we sacrifice increasingly larger amounts of other goods. Graphically, this means the PPC curve of a nation is "concave to the origin." The reason this law holds is that inputs are better suited to some tasks than others (i.e. they are "imperfect substitutes" for each other).In economics, we assume that our wants and needs are ___________ our ability to satisfy themgreater thanWhich of the following best describes what economists assume is true about human behavior?People make rational decisions about how to allocate scarce resources and are motivated by self interestMost college students work outside of school, but they typically work at jobs unrelated to their future career plans, i.e. at restaurants or other part-time jobs.

Calculated as the Absolute Value of (The Percentage Change in the Quantity Demand of a Good)/(The Percentage Change in the Price of that Good)Inelastic DemandThis occurs when demand is not very responsive to price changes. Specifically, this exists when the percentage change in quantity demanded of a good is less than the percentage change in the price of that good. Equivalently, this exists when pEd < 1.Elastic DemandThis occurs when demand is quite responsive to price changes. Specifically, this exists when the percentage change in quantity demanded of a good is greater than the percentage change in the price of that good.

This "law" explains why the U.S. agricultural sector has declined as a percent of the U.S. economy, while sectors like financial services have grown as a percent of the U.S. economy.Cross-Price Elasticity of Demand (xpEd)A measure of the responsiveness of demand for some good X when there is a change in the price of some other good Y. Calculated asSubstitute GoodsGoods/services that serve (at least to some degree) the same purpose to buyers. (e.g. PDQ gas and Kwik Trip gas).

Equivalently, two goods with a cross-price elasticity of demand, xpEd > 0.Complementary GoodsTwo goods/services which are often consumed together. (e.g. cars and gasoline). If the price of one good/service rises (falls), the demand for the other good/service falls (rises). Equivalently, two goods with a cross-price elasticity of demand, xpEd < 0.Independent GoodsTwo goods/services such that if the price of one good/service changes, the demand for the other good/service is not impacted at all. Equivalently, two goods with a cross-price elasticity of demand xpEd = 0.DemandThe entire relationship between each possible price of a good and the corresponding quantity the consumer would be willing and able to purchase, "ceteris paribus."Ceteris ParibusLatin phrase, meaning "all else held constant" or "all else equal." This modeling assumption allows us to focus only on the relationship between the two variables of interest with all other factors not being allowed to change.Law of DemandIf the price of an item falls (rises), then buyers are willing to buy more (less) of it, ceteris paribus. Graphically, this law means the Demand curve is negatively-sloped (with a few exceptions where the curve is vertical or horizontal).The Income EffectAs the price of a good rises (falls), the purchasing power of your dollars of income falls (rises). This is one explanation of the "Law of Demand."The Substitution EffectAs the price of a good rises (falls), that good becomes more (less) expensive relative to other goods, whose prices haven't changed. People will substitute toward relatively cheaper goods and away from relatively more expensive goods. This is one explanation of the "Law of Demand."Marginal utilityThe additional utility gained from consuming one additional unit of a good.Law of Diminishing Marginal UtilityAs additional units of a single good are consumed, eventually the additional/marginal utility derived from each additional unit of the good decreases. This is one explanation of the "Law of Demand."SubstitutesTwo goods/services that serve roughly the same purpose to buyers. (e.g. PDQ gas and Kwik Trip gas). If the price of one good/service rises (falls), the demand for the other good/service rises (falls).ComplementsTwo goods/services which are often consumed together. (e.g. cars and gasoline). If the price of one good/service rises (falls), the demand for the other good/service falls (rises).Inferior goodA good whose demand falls (rises) when buyers' incomes rise (fall).

Graphically, this shows as a movement down and to the right along a given demand curve to a larger quantity as the price goes down."Decrease in Quantity Demanded"This happens ONLY when there is an increase in the price of the good in question. Graphically, this shows as a movement up and to the left along a given demand curve to a smaller quantity as the price goes up."Increase in Demand"This happen when something other than the price of the good itself changes and causes people to be willing to buy more of the good at any given price. Graphically, this is shown as a SHIFT of the whole demand curve to the right. (see the class handouts for examples of what might cause this increase)."Decrease in Demand"This happen when something other than the price of the good itself changes and causes people to be willing to buy less of the good at any given price. Graphically, this is shown as a SHIFT of the whole demand curve to the left. (see the class handouts for examples of what might cause this increase).SupplyThe entire relationship between each possible selling price of a good and the corresponding quantity firms would be willing and able to produce for sale, "ceteris paribus."Law of SupplyIf the selling price of a good rises (falls), the firms/sellers are willing to sell more (less) of that good, ceteris paribus. Graphically, this means the Supply curve is positively-sloped (with a few exceptions where the curve is vertical or horizontal)."Increase in the Quantity Supplied"This happens ONLY when there is an increase in the selling price of the good in question. Graphically, this is shown as a movement up and to the right along a given supply curve to a larger quantity as the selling price goes up."Decrease in the Quantity Supplied"This happens ONLY when there is a decrease in the selling price of the good in question. Graphically, this is shown as a movement down and to the left along a given supply curve to a smaller quantity as the selling price goes down."Increase in Supply"This happen when something other than the selling price of the good itself changes and causes firms/suppliers to be willing to produce more of the good at any given selling price. Graphically, this is shown as a SHIFT of the whole supply curve to the right. (see the class handouts for examples of what might cause this increase)."Decrease in Supply"This happen when something other than the selling price of the good itself changes and causes firms/suppliers to be willing to produce less of the good at any given selling price. Graphically, this is shown as a SHIFT of the whole supply curve to the left. (see the class handouts for examples of what might cause this increase).SubsidyA payment given to firms or individuals when they undertake a particular activity or produce a particular product. This is the opposite of a tax.MarketAn institution or mechanism allowing buyers (demanders) and sellers (suppliers) to make exchanges.Equilibrium Price and Equilibrium QuantityThe price and quantity of a good such that quantity demanded equals the quantity supplied. In equilibrium, there is NO shortage or surplus. Graphically, the market equilibrium price and quantity occur where the Supply and Demand curves cross each other.Price floorA minimum price allowed by law for a given good or service (e.g. minimum wage).Price ceilingA maximum price allowed by law for a given good or service (e.g. rent controls).ShortageWhen quantity demanded exceeds quantity supplied. This typically occurs when the existing price is "too low" (i.e. when the existing price is below the market equilibrium price).SurplusWhen quantity supplied exceeds quantity demanded. This typically occurs when the existing price is "too high" (i.e. when the existing price is above the market equilibrium price).1.
