Explanation of Solution

The Keynesian transmission mechanism maintains that money supply affects the aggregate demand through the changes in rate of interest or exchange rates. That is, the Keynesians maintains the indirect transmission mechanism.

Macroeconomics (Book Only), Chapter 15, Problem 1VQP

In Figure 1, panel (a), (b), and (c) represents the operation of Keynesian transmission mechanism. Panel (a) represents the money market, in which a rightward shift in the money supply from S1 to S2 reduces the rate of interest from I1 to I2. Panel (b) represents the investment goods market, in which a decrease in interest rate increases the investment. Panel (c) represents the goods and service market. Here, an increase in investment increases the total expenditure and shifts the aggregate demand curve to the right. As a result, there is an increase in real GDP from Q1to Q2. From this, it is clear that an increase in money supply affects the aggregate demand indirectly via changes in the interest rate.

Round Tree Manor is a hotel that provides two types of rooms with three rental classes: Super Saver, Deluxe, and Business. The profit per night for each type of room and rental class is as follows. Rental Class Super Saver Deluxe Business Room Type I Type II $30 $35 $20 $30 $40 Round Tree's management makes a forecast of the demand by rental class for each night in the future. A linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. The demand forecast for a particular night is 140 rentals in the Super Saver class, 50 rentals in the Deluxe class, and 40 rentals in the Business class. Round Tree has 100 Type I rooms and 120 Type II rooms. (a) Formulate and solve a linear program to determine how many reservations to accept in each rental class and how the reservations should be allocated to room types. (Assume S₁ is the number of Super Saver rentals allocated to room type I, S₂ is the number of Super Saver…
