Question: The following table gives data for the manufacturing sector of the Greek economy for the period 19611987. a. See if the CobbDouglas production function fits

The following table gives data for the manufacturing sector of the Greek economy for the period 1961€“1987.

Capital-to-Labor Labort Observation Capital Output* Ratio 1961 35.858 59.600 637.0 0.0936 643.2 1962 37.504 64.200 0.099


a. See if the Cobb€“Douglas production function fits the data given in the table and interpret the results. What general conclusion do you draw?

b. Now consider the following model:

Output/labor = A(K/L)βeu

where the regressand represents labor productivity and the regressor represents the capital labor ratio. What is the economic significance of such a relationship, if any? Estimate the parameters of this model and interpret your results.
