A math department consisting of p faculty members, F1; F2; : : : ; Fp, will offer p
courses, C1;C2; : : : ;Cp, in the coming semester and each faculty member will teach exactly one course. Based on personal preferences, each faculty member names his or her first and second choices for a course.
A. We say that a course assignment is a feasible assignment if every faculty member teaches either their first or second choice course. Formulate the problem of finding a feasible assignment as a shortest path, max flow, or min-cost flow problem.
B. A feasible assignment is said to be k-feasible if it assigns at most k faculty members to their second choice course. Formulate the problem of finding a k-feasible assignment for any given k, as a shortest path, max flow, or min-cost flow problem.
C. We say that a feasible assignment is an optimal assignment if it maximizes the number of faculty members assigned to their first choice course. Formulate the problem of finding an optimal assignment as a shortest path, max flow, or min-cost flow problem.

Explain finding a feasible assignment as a shortest path
: We say that a course assignment is a feasible assignment if every faculty member teaches either their first or second choice course. Formulate the problem of finding a feasible assignment as a shortest path, max flow, or min-cost flow problem.

What have we witnessed if price level now remains constant
: The economy is initially in long-run equilibrium. The AD curve shifts to the right and the price level rises. Assuming that the economy is self-regulating, the SRAS curve will shift to the left and the price level will rise even further.

What happens in the simple quantity theory of money version
: Suppose we are at a long-run equilibrium point in an AD-AS model. Then the money supply falls. In the short run, is there any difference between what happens in the simple quantity theory of money (SQTM) version and the monetarist version of the m..
