Week 1 Notes • Titanic example of macroeconomics-the ship is the economy and its difficult for the economy to respond to an immediate iceberg approaching because the economy/ship is too big to shift its course that swiftly • Scarcity-restricts options and demands choices, resources are limited • Opportunity cost-the price you paid/the thing you gave up in order to get something • Utility-pleasure or satisfaction • Marginal-extra, additional • Marginal analysis-comparison of marginal benefit and marginal cost • We assume everyone acts with rational self-interest, not selfishly • Other-things-equal/ceteris paribus-the things that aren’t being studied are assumed to have no effect on the results (Pepsi example-we assume we only change the price of Pepsi, not price of Coke or taste of Pepsi etc.) • Microeconomics-the study of individual consumers, firms, or markets (ex. increase in the market of fashion) • Macroeconomics-the study of the market more generally/the entire market (ex. the unemployment of the United States) • Positive economics-economic statements that can be true or false, factual (ex. the economy fell 3 points yesterday) • Normative economics-economic statements that involve value judgment, up for debate (ex. the unemployment rate ought to be lower) • Economizing problem-the need to make choices because economic wants exceed economic means • Budget line-a schedule that shows various combinations of two products a consumer can purchase with specific income (ex. DVD’s and books) • Trade-offs-giving up purchasing one thing in order to purchase another • Economic resources-capital (machines, things that go into the production of consumer goods), entrepreneurial ability (innovative ideas, risk taking, bringing resources together), land (natural resources), and labor (manual and intellectual) • Consumer goods-goods that satisfy consumers immediately • Capital goods-goods that help grow economy, goods that help enhance production of consumer goods • Production possibility curves/tables o Law of increasing opportunity cost-as the production of a particular good increases, the opportunity cost of production of an additional unit increases (ex. additional robot is 4 , 3/ ,2 / , and 1 unit of pizza), you have to use less skilled resources or more scarce materials to produce more units (resources are not interchangeable) o Economic growth-trade, additional resources, education, technology that uses resources more efficiently, shifts curve outward o Specialized trade can increase the consumption possibility curve by increasing the production of the good that has a lower opportunity cost of the other country and trade the specialized good for the non-specialized good (ex. opportunity cost for Country A is 1 pizza=1 CD, but Country B will trade 2 pizzas for 1 CD, now Country A can get more CD’s and pizza by specializing in producing CD’s and trading for pizza) • Fallacy of composition-good for one person doesn’t mean good for society (ex. Google maps) • Something can be related but that doesn’t mean that one causes the other (ex. there is a 99% correlation in Maine between the consumption of margarine and the divorce rate, this does not mean that an increase in margarine consumption causes divorces)
