(20 points) Suppose the production function is given by Y=zK0.45N0.55 Consider the following data: (1) Calculate the Solow residual for each year from 1995 to 2007 (hint: don't convert millions to billions or vice versa). (2) Calculate percentage rates of grwoth in output, capital, employment, and total factor productivity for each year from 1996 to 2007. Overall, what factor contributes the least to the growth in aggregate output? Do you see that the 2001 recession makes the growth of GDP slower (in other words, is the growth rate in years 2001-2007 higher or lower than the years 1996-2000)? (Note: use the log-difference to calculate the growth rates)
