- Sarah is considering two investment proposals. Proposal A is to purchase a new computer. Proposal B is to purchase a new printer. She will not buy the printer unless she buys the computer. The relationship between Proposals A and B is best described by which of the following? a. B and A are mutually exclusive b. B is contingent on A c. A is contingent on B d. Not enough information is given to determine a relationshipDiscuss the difference between endogenous and exogenous variables.i. List all the endogenous and exogeneous variables in the model.
- The demand and supply of pizza is defined by the following equations: Qd = D(P, Y ) = 1 + Y − 2P Qs = D(P, PM) = 2 P/PM where, Qd is quantity demand, P is the price of each pizza sold, Y is the average income of consumers, Qs is the quantity supplied, and Pm is the price of inputs used in the production of pizza. (a) List the endogenous and exogenous variables of this model (b) Find the equilibrium price Pe and quantity Qe of pizza as a function of the exogenous variables. (c) Use a simple demand and supply diagram to show what happens to the equilibrium price and quantity when there is an increase in one of the exogenous variables.You and your research partner want to use Instrumental Variable analysis to write an econometrics paper and find causal estimates. Your partner argues that because the residuals and the instrument are uncorrelated, the exogeneity requirement is satisfied. What do you tell your research partner: a) You agree, the exogeneity requirement is satisfied by construction b) You agree, the exogeneity requirement is satisfied by their demonstration c) You disagree, you would need the results of the White Test to make this conclusion d) You disagree, the exogeneity requirement cannot be tested as we do not observe the error terms e) You cannot make any conclusions with the current informationA teacher observes that the mitterm grades of students in the class varies depending on “the number of classes that the student takes”, “the difficulty of the assignments”, and the “stress experienced by the student”. She assigns to you the task of doing a research project on this and wants you to do the following: a. Give the project a suitable title b. What is the research question? c. Clearly label the variables (dependent and independent) d. Develop three hypotheses
- Which of the following statements about the inclusion of dummy variables in econometric equations is false? a- The dependent variable on the left side of an equation can be a dummy variable b- An equation can have both a slope dummy an intercept dummy on the right hand side c- If there is a dummy variable as the dependent variable on the left side of an equation, intercept dummy cannot be placed as the explanatory variable on the right side; only a slope dummy can be placed on the right side d- If there is a dummy variable as the dependent variable on the left side of an equation, both intercept and the slope dummy can be placed as the explanatory variable on the right side What is the answer?Which of the statements best describes an exogenous variable in an economic model? An exogenous variable is a variable whose value does not have a relationship with the other variables in the model. An exogenous variable is a variable whose value is not included in the model An exogenous variable whose value does not change as the state of the economy changes An exogenous variable is a variable whose value does change as the stae of the economy changesVariables typically included in a multivariate demand function (other than the price and quantity of the item the demand function represents) are consumer tastes and preferences, the number of buyers, spendable (disposable) income, prices of substitute goods, prices of complementary goods, advertising expenditures, weather, and expectations. Recalling that the price of the item being considered is placed on the vertical axis, and the quantity on the horizontal axis, the other variables are termed demand shifters. Please answer the following questions about the affect changes in other variables might have on the demand for the item. These changes will either cause demand to increase (shift right) or decrease (shift left). Use either word as applicable, for the short answer. If the price of a good increases because the demand for it increases, What would you expect the demand for its complement to do? If the demand for coffee beans increases, then what is likely to happen…
- You have been tasked with developing a research report based on an economy of your choice anywhere in the world. The economy you select should be a growing economy or an economy that has experienced growth at some stage in its development. Present the finding of your research under the following headings. DETERMINANTS OF DEMAND Identification and in-depth discussion of the determinants of demand that have led to an increase in market demand in one of the critical industries in your chosen economy. (Make reasonable assumptions where necessary). (250 - 300 words)Suppose you have been hired by a research firm trying to understand the market for Widgets (a hypothetical product). Your analysis of the data indicates that the Demand curve for Widgets is estimated to be linear and given by equation Qd = 150 – 3P and the Supply curve for Widgets appears to be linear as well and is estimated as Qs = 2P – 20. Graphically draw these two curves, labeling all relevant points (such as intercepts for each line) on the horizontal and vertical axes.Consider the following Model (notation is standard):C=c(y-τ) I=i(r) y = C+I+G Md/P = L(y, r) Md= Ms=My = f(n) n = h(W/P) f´(n) = W/P Calculate the effects of a change in τ on C, I, r, y and P.
