What is econometrics? correct answers Tools of economic theory, math, and statistical inference are applied to the analysis of economic phenomena. How do we do econometrics? What are the steps involved? correct answers 1. Make a hypothesis 2. Collect data 3. Specify the model 4. Estimate the parameters 5. Check model specification - is the model good? 6. Test the hypothesis 7. Use the model to predict or forecast or answer questions Simple linear model correct answers yi= B1 + B2Xi +...

Using the notation of the text, letting β0 = 3.0 and β1=2.0 in a regression model implies that: correct answers Y is expected to increase by 2.0 units if X increases by 1 unit If R^2 = 0.8, then correct answers SSR/TSS = 0.2 In a linear regression the one regressor, the standard error of the regression (SER) is defined as correct answers sqrt(SSR/(n-2)) In the simple linear regression model, the regression slope correct answers indicates by how many units Y increases, given a one unit...

When there are omitted variables in the regression, which are the determinants of the dependent variable, then: correct answers the OLS estimator is biased if the omitted variable is correlated with the included variable If you have a regression model with two x's (independent variables), then omitting one variable which is relevant: correct answers can result in a negative value for the coefficient of the included variable, even though the coefficient will have a significant positive effect...

2a) Let income denote the person's income and age denote the persons age. We would like to run an OLS regression on the equation BMI=B0+B1fast+B2income+B3age+U. Write down all the assumptions that guarantee that the OLS estimators of the coefficients of this equation are unbiased correct answers 1)Linearity- E[U|fast, income, age]=0, The expected value of y is linear in X1,X2,X3 2)Exogeneity- E[U|fast, income, age]=0, unobservables are constant and do not effect BMI 3)Random Sampling- The dat...
