The OzLand government is interested in whether trade union membership has a causal impact on a worker’s wages.  Theory suggests that trade union membership can directly affect a worker’s wages; and as well can indirectly increase a worker’s wages by increasing their job tenure (length of time working for the same employer).  You are asked to advise on the type of regression model that the government should estimate.  The dependent variable in the regression is wages of individual workers.  If the government wants to estimate the causal impact of trade union membership on wages it {should/should not} include job tenure as an explanatory variable in addition to a variable for union membership.  Whereas if the government wants to make the best prediction of an individual worker’s wages it {should/should not} include job tenure as an explanatory variable in addition to a variable for union membership.  What is your advice?Group of answer choicesCausal impact: Should not; Prediction: ShouldCausal impact: Should; Prediction: ShouldCausal impact: Should not; Prediction: Should notCausal impact: Should; Prediction: Should not

A leader of the Workers Union in New Zealand would like to study the movement in the average hourly earnings of New Zealand workers. He collected and recorded data on average earnings (AE, $), labour cost[1] (LC, $) and rate of inflation (RI, %). His data are saved in the t9e3 file.a) Set up a suitable regression model to investigate the impact of labour cost and rate of inflation on the hourly earnings of an average New Zealand worker.b) Do you expect the slope parameters to be positive or negative?c) Estimate the regression model.d) Do the estimated slope coefficients have the logical signs? Carefully explain the meanings of the estimated slope coefficients.e) What do the unadjusted and the adjusted coefficients of determination tell you about the quality of the fit?
