1>On the long-run aggregate supply curve, * An increase in the price level increases the aggregate quantity of GDP supplied
An increase in the price level increases the level of potential GDP
An increase in the price level reduces the aggregate quantity of GDP supplied
An increase in the price level has no effect on the aggregate quantity of GDP supplied
2>Suppose that firms become more optimistic about the future profitability of new investment. Which of the following will happen in the short run? *
Price level will decrease
Aggregate demand will shift to the left
Output will decline
Unemployment will decline
3> A fall in the foreign exchange rate of the dollar *
Increases aggregate demand
Increases the aggregate quantity demanded
Decreases the aggregate quantity demanded
Decreases aggregate demand
4> Which of the following is true about the long- run aggregate supply curve? *
It is vertical at the level of potential GDP
It does not shift in response to temporary changes in aggregate demand
It shows the relationship between the price level and real GDP when wages and other costs are at an equilibrium level
All of the above
5> Because of the slope of the aggregate demand curve we can say that *
An increase in the price leads to a higher level of real GDP demanded
A decrease in the price level leads to a higher level of real GDP demanded
An increase in the price level leads to a shift in the aggregate demand curve
A decrease in the price level leads to a shift in the aggregate demand curve

Imagine us is a startup that offers high definition 3d prenatal ultrasounds for high-end customers. the service process includes four activities that are conducted in the sequence described below. (the time required for each activity is shown in parentheses): activity 1: welcome a patient and explain the procedure. (20 minutes)activity 2: prep the patient (e.g., show them to the room, apply ultrasound gel). (17 minutes) (*your id number represents the amount of time needed to complete this task)activity 3: take images. (5 minutes)activity 4: discuss diagnostic with patient. (20 minutes)at each location there are employees (servers) s1, s2, and s3. the assignment of tasks to servers is the following: s1 does activities 1 and 2.s2 does activity 3.s3 does activity 4.a. what is the capacity of this process (in customers per hour)? b. suppose 3 patients arrive every hour on average. ignoring any “start of day” or “end of day” effects, what are the utilizations of all three servers (%)? c. suppose each activity can be done by any server and any server can do any set of activities. however, each activity is done by only one server. for example, a possible assignment includes: s1 does activity 1, s2 does activity 2, and s3 does activities 3 and 4. of course, the original assignment of servers to activities is also feasible. what is the maximum capacity of the process (in customers per hour)? d. now consider the capacity measures in (c) and (a), what is the percentage change? why can you improve capacity without using additional resources? (there is no free lunch, right? )note: for all hw assignments, show your process of getting the results. only providing the final answers is not acceptable and will get 0%. if necessary, use a separate sheet of paper to show your work.
