Suppose the production function is given by: Y = K 1 3 (AN) 2 3 . The savings rate s is equal to 10%, and the depreciation rate delta is equal to 5%. Also, assume that the number of workers increases by 2% per year, and the rate of technological progress is 3% per year. 1. Find the steady-state values of: 3 (a) Capital per effective worker (b) Output per effective worker (c) Growth rate of capital, output and consumption per effective worker (d) Growth rate of capital, output and consumption per worker (e) Growth rate of capital K total output Y 2. According to your findings in (1), does the model exhibit a balanced growth? 3. Now, suppose that the rate of technological progress doubles to reach 8% per year. What happens to the answers to question 1? Justify. 4. Suppose now that the rate of technological progress remains at 4% per year, but the growth rate of the number of workers increases to 6% per year. What happens to the answers to question 1 ? Justify.

Shen is stranded in a war zone in a foreign land. His only chance of survival is to reach Sudland, which lies 100 miles away. There are just two routes to Sudland; one is through a desert, and the other is a long and perilous trek through the mountains. Both routes are terribly dangerous. In the past, 38% of all who tried to reach Sudland failed. Of all attempts to reach Sudland, 7 out of every 29 were by the desert route. Although it is the longer route, the mountains seem to provide more success: 69% of those who attempted to reach Sudland through the mountains were successful. To save time, Shen intends to go via the desert. What are his chances of making it through to Sudland? Round your answer to two decimal places. (If necessary, consult a list of formulas.)

A heat exchanger has the following transfer function model: \begin{equation*} G_\nu(s) = \frac{3e^{-4s}}{15s+1}, \quad G_\theta(s) = \frac{2e^{-7s}}{10s+1} \end{equation*}with $G_\nu = G_m = G_t = 1$. (a) Design a feedforward controller based on a steady-state analysis. (b) Design a feedforward controller based on a dynamic analysis. (c) Design a PI feedback controller based on the ITAE method for PI disturbance case. (d) Simulate the closed-loop response to a unit step change in the disturbance variable using feedforward control only and the controllers of parts (a) and (b). Does the dynamic controller of part (b) provide a significant improvement? (e) Repeat part (d) for the feedforward-feedback control scheme and the controllers of parts (a) and (c), as well as (b) and (c). (f) Which control configuration provides the best control?
