4、 J. J. SimidianSimidian, 2007., 2007.3Chapter OneProfessor Greg Mankiw is not only a prolific, talented, and ingenious economist, but humble and kind-hearted. His unique and extraordinary creative ability to impart knowledge makes him both an economist and artist. I am so honored and grateful again
5、be a part of supplementing his unprecedented craftsmanship.My mentor, and friend for over a decade Professor Mike McElroy (North Carolina State University) was the first to see the novelty in these tutorials while I was an undergraduate student at Duke University. His contributions and influence wil
6、l be a part of my work indefinitely. My gratitude is endless as well to Professors David Denslow, Mark Rush, Ed Tower, and Jeff Frankel.My love and gratitude goes to my dear friend and surrogate father Dr. Lawrence Brockman, D.M.D, an endodontist but an economist in spirit who has been my teacher, i
7、nspiration and dearest friend for over a decade. I also want to thank the following special people in my life: my mother, Jane, Michael Hill, Elle at any given price, pizzerias find that the sale of pizza is more profitable, and thus the supply of pizza rises. This translates into a rightward shift

Result: price falls, quantity rises.Result: price falls, quantity rises.P PD DS SQ QS S 9Chapter OneEconomists typically assume that the market will go into an equilibrium of supply and demand, which is called the market clearing process. This assumption is central to the pi
9、zza example on the previous slide. But, assuming that markets clear continuously, is unrealistic. For markets to clear continuously, prices would have to adjust instantly to changes in supply and demand. But, evidence suggests that prices and wages often adjust slowly.So, remember that although mark

Market-clearing models may not describe every instant in an economy, but they do depict the equilibrium toward which the economy gravitates.10Chapter OneMicroeconomics is the study of how ho
11、useholds and firms make decisions and how these decision makers interact in the broader marketplace. In microeconomics, an individual chooses to maximize his or her utility subject to his or her budget constraint.Macroeconomic events arise from the interaction of many individuals trying to maximize
12、their own welfare. Because aggregate variables are the sum of the variables describing individuals decisions, the study of macroeconomics is based on microeconomic foundations.11Chapter OneThe modules mirror the sequencing of the text, Macroeconomics, 7th ed.
