Eliza Barrett 1/8/2016 Econ 2000 Lecture 1 Introduction to Economics: 5 Foundations Chapter One - What is economics? The study of how people allocate their limited resources to satisfy their nearly unlimited wants and needs. • Scarcity: Refers to the limited nature of society’s resources, given society’s unlimited wants and needs. Everything is scarce. - Two Branches of Economics • Microeconomics: The study of individual units that make up the economy • Macroeconomics: The study of the overall aspects and workings of the economy The Five Foundations 1. Incentives matter 2. Life is about trade-offs 3. Opportunity costs 4. Marginal thinking 5. Trade creates values - 1. Incentives • Factors that motive you to act or exert effort. People respond to incentives! - Types of incentives: • Positive: Tax refund, pay raise, employee of the month, • Negative: Taxes, jail, fees, fines, failing class, getting fired • Direct: Clear trade off happening (example: Come to our party to get free pizza!) • Indirect: unintended consequences (less incentive to stay home and study, if at party getting free pizza) • Incentives and unintended consequences - Australia was experiencing declining birthrates in early 2000s. Government implemented a baby bonus of $3,000 for all babies born on or after July 1st, 2014. • What type of incentive is this? Positive direct incentive Potential unintended consequences? Unhealthy for delaying birth with harsh cut off, • government spending a lot of money, baby boom - 2. Trade Offs • Scarcity—> give up something to get something else. - Examples: • Eating donuts for breakfast instead of a bowl of fruit. • Attending Clemson means giving up attending another school • Taking four hours to watch a movie or watch a couple of TV shows - 3. Opportunity Costs • The highest-valued alternative that must be sacrificed in order to get something else. - Notice that it is not every alternative, just the next best one. - The economic cost of something is the cost of what you give up to get it. • Examples: - Opportunity cost of going to a “free” concert in Clemson the evening of Monday, January 11th. • The lost opportunity to watch the Clemson vs.Alabama football game - How do you decide? • Minimize opportunity cost by selecting the option that has the largest benefit. - What’s the cost of attending college? • You have to pay for tuition, textbooks, etc. What are you sacrificing? - If not attending college, you would likely have a full-time job - Cost of attending college includes this income which you have to give up - 4. Marginal Thinking • Evaluating whether the benefit of one more unit of something is greater than the cost of that unit. - Examples: • Driving down the highway to another town slightly over the speed limit, is it worth getting there earlier in risk of getting a speeding ticket. • Eating one more slice of pizza, the value of the pizza goes down the more you eat. • One more hour of studying, decide this based on other things you could be doing (sleeping, eating, etc). - 5. Trade Creates Value • Markets bring buyers and sellers together to exchange goods and services - Trade: The voluntary exchange of goods and services between two or more parties • Is there a winner and a loser in every trade? NO, just winners. Trade only occurs if both parties feel they gain from the trade and are better off than they were before. Lecture 2 - Trade requires people to create different things - ComparativeAdvantage – when an individual (or business or country) can produce at a lower opportunity cost than a competitor can. Ceteris Paribus • Latin for “Other things being equal” or “All else equal” Exogenous variables • Variables that are determined outside of the model Danger of FaultyAssumptions • Using faulty assumptions can lead to spectacular policy failures. • It is necessary to often examine and re-evaluate the assumptions in models. • Example:Assumption that housing prices always rise • Pre-2008, banks’computer models did not include a variable for declining housing prices. 1/13 Lecture 3 Gains from trade: comparative advantage Specialization and Gains from Trade Production Possibilities Frontier • Gilligan and Skip live on an island. They have limited resources (time), which they use to produce two things • Gilligan: 20 coconuts; or 10 fish • Skip: 40 fish, 20 coconuts - AbsoluteAdvantage: the ability of one producer to make more than another producer with the same quantity of resources • Fish? Skip • Coconuts? Neither - ComparativeAdvantage: the ability to make a good at a lower opportunity cost than another producer. Look at who is giving up less compared to the other thing. • Coconuts? Gilligan - coconuts/fish= 20/10= 2 - fish/coconuts= 10/20=1/2 • Fish? Skip - coconuts/fish=20/40=1/2 - fish/coconuts=40/20=2 - Specialization and Trade: specialization allows for greater productivity and growth • Without trade: Assume Gilligan and Skip each split their time between producing fish and coconuts - Gilligan produces and consumes 5 fish and 10 coconuts - Skip produces and consumes 20 fish and 10 coconuts • Total: 25 fish and 20 coconuts • With Trade: - What does Gilligan produce? 20 coconuts - Skip? 40 fish • Gilligan willing to trade 10 coconuts for 10 fish (it would cost him all 20 coconuts to catch 10 fish himself) • Skip accepts (he could only get 5 coconuts himself in the time he can catch 10 fish) • Gilligan consumes 10 fish and coconuts • Skip consumes 30 fish and 10 coconuts 1/15 Lecture 4 MC vs MC - Arational choice is always to consume up to the point where MC= MB • If MB>MC then do it • If MB<MC don’t Chapter 3: Supply and Demand Markets and Competition - Firms: supply goods and services - Consumers: want to purchase goods supplied by firms - Exchange happens through established prices in markets - Supply or demand factors can change the market price - Markets exist wherever goods and services are exchanged • grocery store • stock market • real estate • amazon.com - Acompetitive market has • many buyers and sellers • price takers (no one person sets the price) - Monopoly • single seller that supplies the entire market for a good or service • DeBeers diamond company owned 90% of world’s diamonds in early 1900s - Monopsony • when a market has a single buyer, who has an influence on the price Demand - Quantity Demanded: The amount of a good purchased at a given price • Not the same as “Demand” - Law of Demand: Ceteris Paribus, there is an inverse relationship between price and quantity demanded • If the price goes up, people demand less of the good, and vice versa - Demand schedule • Table showing the relationship between each quantity demanded and price - Demand curve • graphical representation of the schedule - When “demand” is referred to, it means the curve and the schedule Market Demand - Adding up each individual’s demand at each price - IF: • At a price of $1/lb for shrimp - Dan demands 4 lbs - Jenny demands 5 lbs • Then the market demand would be 9 lbs of shrimp Change in quantity demanded vs. change in demand - Movement along the demand curve is a change in the quantity demand • caused by a change in the price of the good - Ashift of the entire demand curve is a change in demand • caused by a change in something other than price • can also think of changing the demand schedule - Increase in demand • a shift out/up to the right - Decrease is a shift in/down to the left Demand shifters - changes in income - price of related goods - changes in tastes and preferences - future expectations - number of buyers in the market
