Visit the Bureau of Labor Statistics of the U.S. Department of Labor at www.bls.gov/data. See if you can find monthly time series of private sector weekly earnings between January 2008 and 2018 and the consumer price index over the same period. Use the data to plot the nominal and real increases in weekly earnings over the eleven-year period. (Nominal increases are based on the actual quoted hourly rates, while real increases are obtained by first adjusting the actual quoted rates by dividing them by the inflation or consumer price index). How might these graphs and data prove useful for a company?
