Linear Algebra

- Consider the Acemoglu, Johnson, and Robinson (2001) data on economic development and property rights from class.

a) Regress log GDP per capita in 1995 (logpgp95) on the measure of property rights(avexpr) and report your results. Use hetereoskedasticity-robust standard errors.

b) Construct 95% confidence intervals for the intercept and slope coefficients.

c) Test Ho : B1 = 0 against Hị : B1 > 0. In answering, be sure to report the test statistic and p-value.

d) Test Ho : B1 = 0.5 against H1 : B1 > 0.5. In answering, be sure to report the test statistic and p-value.

e) Test Ho : B1 = 0 against H1 : B1 < 0. In answering, be sure to report the test statisticand p-value.

f) Test Ho : B1 = 0 against H1 : B1 # 0. In answering, be sure to report the test statistic and p-value.

g) Repeat parts b)–f) using homoskedasticity-only standard errors. Do your results change?

h) Plot the regression residuals against avexpr. Does this explain your answer to g)?Hint: You will need to use the command

Linear Algebra

In an election campaign, the popularity, B, as a percent of voters, of the governing Blue party can be modelled by a function of time, t, in days throughout the campaign as B(t) = 40 - 0.5t. The popularity, R(t), of the opposing Red party can be modelled by a composite function of B(t),R(B(t)) = 20 + 0.75[40 – B(t)].
Graph B(t) and describe the trend.
