Question details

Regressions. You are interested in analyzing whether states with higher banking regulation have higher unemployment rates than states with lower banking regulation. You have the following cross-sectional data on 4 states. unemployment rate is the states unemployment rate measured as a percent. regulation index is a sum of dummy variablès that describes the number of banking regulations implemented by the state. 3. state unemp rate C regulation index Estimate the coefficients (A-A) of the linear model shown below using OLS and write the resulting regression equation a) unemp rate, = β。+ ARegulation Index s + Es b) Interpret each of the coefficients (Bo. B1) in this regression. c) What sign would you expect B to have? Explain your reasoning. d) Give one alternative explanation for B1 to be the opposite sign of what you answered in question 3c. (e.g. if you said you expect pi to be negative, describe a scenario where the relation between regulation and unemployment rates is positive). Suppose you then think that states with higher unemployment rates may have different incentives to implement banking regulation than states with low unemployment rates. How would you modify the linear regression model in question 3.a to reflect this change? (Hint: Think about how dependent and independent variables appear in the regression model.] e) D Estimate the coefficients of the linear model you specified in question 3.e g) Interpret the coefficients (Bo.B) in this new regression (from question 3.f h) Calculate the prediction error for each state under each model Prediction error Prediction error under model 3.a under model 3,f state i) Which regression appears to generate more accurate predictions?
