Homework (Ch 23) 9. Economic fluctuations II The following graph shows the short-run aggregate supply curve (AS), the aggregate demand curve (AD), and the long-run aggregate supply curve ( LRAS) for a hypothetical economy. Initially, the expected price level is equal to the actual price level, and the economy is in long-run equilibrium at its natural level of output, $110 billion. Suppose a bout of severe weather drives up agricultural costs, increases the costs of transporting goods and services, and increases the costs of producing goods and services in this economy. Use the graph to help you answer the questions about the short-run and long-run effects of the increase in production costs that follow. (Note: You will not be graded on any adjustments made to the graph.) Hint: For simplicity, ignore any possible impact of the severe weather on the natural level of output. 130 LRAS
