Q1: Download the data WDI.zip from the course site.
Q2: Build and estimate a regression to explain the factors which drive infant mortality rates. Justify your modeling choices with economic intuition and econometric evidence. Things you may want to consider include (but are not limited to) logs vs. levels, non-normality, outliers, sample selection, omitted variables, measurement error, multicollinearity, and group/interaction effects.
Q3: Determine whether your regression errors are heteroskedastic and correct for this heteroskedasticity using (i) robust standard errors and (ii) FWLS to obtain a potentially more efficient estimator. Compare all of your results.
Q4: Present and interpret your results thoroughly. Are the factors you isolate casual? Why or why not? What are the most important factors determining infant mortality? Assess the validity and strength of your results.

Describe the factors that the auditors should consider in evaluating oral evidence provided by client officers and employees.
An electric switch manufacturing company has to choose one of the three different assembly methods. Method A will have a first cost of $40,000, an annual operating cost of 9,000 and a service life of 2 years. Method B will cost $80,000 to buy.
Assume that there is no substitution effect from changes in wages. Use two graphs to show the effects of the increase in the wage on the quantity of labor demanded.
Compute the discount factor 1/(1+r)^t for r=1, 5, or 10 perent interest rates and t=30 and 50 years. remember that 1 percent is .01. based on your computation, is teh choice of discount factor important for deciding whether to do somehtinga bout g..
Assume a consumer with the utility function U= U (X, Y) = (X + 2) (Y + 1) And the budget constraint (M = 95, Px =10 and Px =5) 95 = 10x + 5Y a. Set up the constrained maximization problem, and derive the first-order conditions.
A researcher is interested in the size of the current balance of credit card holders. To estimate this, he obtains the size of the current balance of a random sample of 25 credit card holders. A 90% confidence interval for the mean current balance..
Determine the uniform quarterly series in quarters 0 through 12 of a cash inflow of $5,000 in quarter 1; $10,000 in quarters 2 to 5; and $12,000 in quarters 6 - 12 with an interest rate of 15 %.
Find the general expression for the consumer's expected utility maximization problem for investing x dollars in the risky asst.Let u(w) represent the general utility function.Characterize the solution to this problem by finding the first order con..
Your own in-house staff will be responsible for integration and quality control. Because the software and the PBC are contract items, you must carefully monitor the integration phase.
compute the standard error of estimate and the standard error of the coefficient for the following data set: X = 95, 85, 80, 70, 60 and Y = 85, 95, 70, 65, 70. Lastly, set up and perform the hypothesis test to determine if a student's aptitude sco..
Now suppose that there is a second ?rm with cost function c1 (q) above. Whichever cost function ?rm 1 chooses, the second ?rm will observe this choice and then have the option of entering the market or not. If he does not enter, ?rm 1 remains a mo..
Suppose that there are only three types of fruit sold in the United States. Annual sales are 1 million tons of blueberries, 5 million tons of strawberries, and 10 million tons of bananas.
