3) Suppose the Phillips curve can be written as $\pi_t = \pi_t^e + 0.2 - 5u$ a) Derive the natural rate of unemployment for this economy. b) Suppose now that expectations are set via the expression $\pi_t^e = \delta\pi_{t-1}$where $\delta$ is a coefficient governing the response of expected inflation in the current period to actual inflation in the previous period. If $\delta = 0$, what does this say about how expectations are formed? Are the rational or adaptive? What about if $\delta > 0$? c) Assume that $\delta = 0$ and that the government of this country wants to reduce unemployment to 3.0% forever. What would the effect of this policy be on inflation in any given future year? Can this hold intuitively? d) Now suppose that the government insists on holding to the 3% unemployment rate policy. For the first three periods, agents' inflation expectations continue to be uninfluenced by past inflation. Starting in period 4, however, agents begin to wise up and change their expectations for inflation according to $\pi_t = \pi_t^e$. What is the rate of inflation in periods 4-6? Does this make more, or less sense than the outcome in part (c)?

5. (20 pts) An automated drill press requires the DC motor driving the bit to rotate as prescribed by the velocity profile specified in the below figure. The load torque generated from the interaction of the bit with the wood is constant and equal to Load Torque in the graph. The motor is powered by a 14 volt battery. You can assume that you have access to the function my_motor(int duty), which accepts an integer representing the duty cycle as a 10 bit digital number. Velocity[rpms] 1000 Angular velocity [rpm] 1000 Torque Time(s) 10 15 Write the necessary code to achieve this velocity profile within the provided real time interrupt code. You must comment your code. // You don't need to implement the PWM function or the setup. unsigned int ticks = 0; ISR(TIMER1_COMPA_vect)/* timer compare interrupt service routine*/{ ticks++; // ADD YOUR CODE HERE (recall that you can call the function my_motor() with the required duty)

Assignment 1 Problem 1: Write a program that converts pounds into kilo- grams. The program prompts the user to enter a number in pounds, converts it to kilograms, and displays the result. One pound is 0.454 kilograms. Below is a test case: Enter a number in pounds: 55.5 55.5 pounds is 25.197 kilograms Note: Name your Java class Convert. Problem 2: Write a program that reads the subtotal and the gratuity rate, then computes the gratuity and total. For example, if the user enters 10 for subtotal and 15% for gratuity rate, the program displays $1.5 as gratuity and $11.5 as total. Below s a test case: Enter the subtotal and a gratuity rate: 10 15 The gratuity is $1.5 and total is $11.5 Note: Name your Java class Tip.
