Chapter 1 Real GDP- measures the total income of everyone in the economy, adjusted for inflation. Inflation rate- measures how fast prices are rising. Unemployment rate- measures the fraction of the labor force that is out of work. Deflation- is a period of prices falling. Recession- a period of decreased GDP. Depression- a period of prolonged and severe recession. Market clearing- assumes that markets are normally in equilibrium, so the price of any good or service is found where the supply and demand curves intersect. Flexible prices- adjust to equilibrium when market circumstances change. Sticky prices- do not adjust quickly to a changed equilibrium point. Microeconomics- is the study of how households and firms make decisions and how these decision makers interact in the marketplace.

National income accounting- is the accounting system used to measure GDP and many related statistics. Stock- is a quantity measured at a given point in time. Flow- is a quantity measured per unit of time Value added- of a firm equals the value of the firm’s output minus the value of the intermediate goods that the firm purchases. Imputed value- is an estimate of the values of goods and services when including them in GDP. Nominal GDP- value of goods and services measured at current prices.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
