Use appropriate graph(s) to explain the effect of each of the following events, if any, on the position of the short- and long-run aggregate supply curves and the aggregate demand curve for a small open economy. a) The country becomes home to thousands of immigrants who significantly increase its labour force. b) The Central Organization of Trade Unions in the country wins a 10 percent increase in money wage rates for low-income workers. c) There is a decrease in the income of the country's major trading partners. d) The country starts to harness geothermal energy, which it puts to use and sells the excess energy to neighbouring states.

2. The theory of liquidity preference and the downward-slopingaggregate demand curve Suppose the money market for some hypothetical economy is given by the following graph, which plots the money demand and money supply curves. Assume the central bank in this economy (the Fed) fixes the quantity of money supplied. Suppose the price level increases from 90 to 105. Shift the appropriate curve on the graph to show the impact of an increase in the overall price level on the market for money. INTEREST RATE (Percent) 18 15 12 8 3 0 0 20 Money Supply Money Demand 40 60 80 MONEY (Billions of dollars) 100 120 Money Demand Money Supply Following the price level increase, the quantity of money demanded at the initial interest rate of 9% will be supplied by the Fed at this interest rate. As a result, individuals will attempt to bonds and other interest-bearing assets, and bond issuers will realize that they restored in the money market at an interest rate of % than the quantity of money their money…

The following graph shows the aggregate demand curve in a hypothetical economy. Assume that the economy's money supply remains fixed. PRICE LEVEL (CPI) 180 T 150 140 130 120 110 100 90 80 0 Aggregate Demand 100 200 300 400 500 600 REAL GDP (Billions of dollars) 700 800 (?) Which of the following are reasons the aggregate demand curve is downward sloping? Check all that apply. A higher price level makes domestically produced goods more expensive than foreign goods. A lower price level leads to a lower interest rate. A higher price level decreases consumption through the substitution effect. As the aggregate price level rises, the purchasing power of households' saving balances will demanded to This phenomenon is known as the effect. causing the quantity of output
