1. Suppose that we are interested in measuring the relationship between hourly wage and output productivity in the U.S economy. Variables hrwage(t) and outphr(t) denote the average hourly wage and output productivity in the U.S economy for year t. We start by estimating the model specification shown in equation (1) below: log(hrwage) = Bo + B₁ log(outphre) + ut. where log(.) denotes the natural logarithm and ut is the error term.

You model the relationship between citizens' consumption and their monthly income. Based on your experience, you know that people with lower income usually spend 60% of their income on consumption. For people with higher income, some may spend only 40% on consumption, while others spend 70% on consumption. What is the potential problem when you use a linear regression model? E[u\x] #0 Heteroskedasticity Perfect colinearity No variability in x None of above

3) You want to study the effects of disposable income, anti-smoking advertising and cigarette prices on the per capita consumption of cigarettes in US. You collect data on these variables across the 51 states over 20 years. You thus have 51x20=1,020 data points. For each state and year, you measure: Y=per capita consumption of cigarette (the fraction of the state population that smoked in that year); Xı=per capital income in the state (in US$); Xx=total expenditure in anti-smoking advertising in that state (in USS); and X3=average cigarette price in the state (in US$). You can then run a model: Y= Bo+Bi*X++ B2*X+ B3*X3+e Explain how you would test that the model is useful in predicting Y: How you would test the alternative hypothesis that you have at least one of the coefficients B1, ß2 or ß3 is different from zero. (That is, the null is that all three coefficients are zero.) Use a significance level a=0.05. (Again, there is no need to “run" the data. Just explain what you would do.…
A trade policy analyst is planning to assess the relationship between Foreign Direct Investment (FDI) and exports using a panel data of 20 countries over a period of 15 years.
