People usually take advantage of opportunities to make themselves better off Incentives V Allocate Choices Cost What is the opportunity cost Market choice Market system Innovation and productivity Before organizing a market there are some important questions to ask rst What will be produced How will it be produced Who will produce it For whom will it be produced Economic systems and the management of choice How do each of the type of economic systems manage choices in their respective market environments constrained by scarce resources and scarce opportunities How might each of

gt planned socialist Choice gt consumers producers and government gt mixed economy The function of markets in principles Without dividing into the politicized discussion of private versus public economies a mixed marketplace should function along 4 tenets 1 Serve as a medium to coordinate activities in response to private and public incentives signaling unlimited needs and wants in a resource constrained environment 2 Serve as a medium for the allocation of scarce resources through the use of pricing mechanism regulated or nonregulated or adoption of some acceptable private and or public practice 3 Making use of a pricing mechanism for the allocation of scarce resources or adoption of some type of acceptable private or public practice for the allocation of resources land labor and capital to persons or entities that will make for the most productive use of such resources 4 Create exploitable trade and exchange opportunities for participants that will maximize private and public gains and returns to society Comparative vs absolute advantage gt Comparative advantage the opportunity cost of producing the good is lower for that individual than for other people gt Absolute advantage if he or she can do it better than other people Careful DON T confuse comparative advantage with absolute advantage Positive versus Normative Analysis Positive analysis is testable Normative

wages all go up by 2 there is no gal change in your purchasing power People with money illusion think they are richer in this case Nominal wage The wage in current dollars analogous to nominal GDP Real wage Nominal wage adjusted for in ation changes in the price level Another money illusion example If nominal wages go up by 3 but prices go up by 5 money illusion may cause you to think of yourself as wealthier but your real wages have actually decreased Menu costs The costs of changing prices Example a restaurant will have to print new menus for all price changes Uncertainty about

selling an asset for more than its purchase price Problem often the price rises due to in ation rather than an increase in the value of the good Example Buy a house in 1980 for 80000 Sell the house in 2012 for 230000 for a 150000 capital gain You have to pay taxes on this 150000 However the CPI rose from 80 to 230 in those years so the real value of the house is the same Using CPI to compare dollar values across time Prices from different time periods can be confusing In 1924 you could buy a fully constructed house for 1969 To compare we can transform this into a price in today s dollars Price
