- 7. Models: Apply the supply-and-demand model to the following markets. In each case, state the key endogenous variables in the market as well as some important exogenous variables or parameters. Also, express each model as a system of mathematical equations. As an example, Q = F(P, X) might be the demand curve in the computer market, where X captures some exogenous variables like the availability of the iPad or computer games. How many equations are there within each example? How many unknowns? 1. The computer market. 2. The market for your favorite music. 3. The market for a particular currency, such as the dollar, the yen, or the euro. (Hint: This last example suggests an important point about "exogenous variables": what is exogenous in one model, as in a narrow study of the supply and demand for dollars, may be endogenous in a richer model-like a study of the entire U.S. macroeconomy.)14. What assumption is important in using economic model to make predicitons? a) the law of demand b) the rationality assumption c) ceteris paribus/ other things being equal d)evryone being a price takerWhich of these situations describe an equilibrium, and which does not? If not, what would an equilibrium look like? Remember that the definition of equilibrium means, in part, that there is no incentive or push/pull to change from the current described state. Many people regularly commute from the suburbs to the downtown area of a local city. Due to traffic congestion, the trip takes 30 minutes when you travel by highway, and15 when you go by side streets. There are 2 gas stations at the intersection of Main and Vine. One charges $3.75 for regular and the other charges $3.25. Customers can get gas immediately at the first station, but must wait in long lines at the second. Every student who enrolls in econ principles must also attend a weekly tutorial. This semester, 2 sections are offered, which meet at the same time, in adjoining classrooms and are taught by equally competent and liked instructors. Section A is overcrowded with people sitting on the floor and unable to see the board…

An exogenous variable is a variable that is taken as given and is not explained by an economic model. True O FalseIn a microeconomic model, how would you differentiate between an 'exogenous' variable and an 'endogenous' variable? O Endogenous variables are those determined within the model, while exogenous variables are given from outside the model. O Exogenous variables are those which economists do not study, while endogenous variables are heavily studied. O Exogenous variables are variables that economists cannot measure, while endogenous variables are measurable. Exogenous variables cannot influence endogenous variables in any economic model. O More than one of the above.

Why isn’t it useful to construct an economic model that contains only exogenous variables (and no endogenous variables)?Please help me with this macroeconomics question! 4
- Define the Market Economy term and provide an original, economics-based explanation of the term. Aslo provide a real/hypothetical contextual example (different from that provided in the text) of the term as it is applied to economics.14. Consider the following figure. Describe and explain what this figure presents and the economic forces that this figure summarises. Please keep your answer short and to the point. Unnecessarily long answers that include irrelevant information will be penalised.Macroeconomics: What effect will each of the following have on the demand for small automobiles such as the Honda Civic or Ford Focus? A supply schedule or curve shows that, other thingsequal, the quantity of a good supplied varies directlywith its price. The supply curve shifts because of changes in (a) resource prices (b) technology (c) taxes or subsidies (d) prices of other goods (e) expectations of futureprices (f) the number of suppliers A change in supply is a shift of the supply curve; achange in quantity supplied is a movement from onepoint to another on a fixed supply curve. Questions: Consumers anticipate that the price of small autos will greatly come down in the near future. The price of gasoline substantially drops.
