Question

Draw an aggregate demand and supply diagram for Japan. In the diagram, show how each of the following affects aggregate demand and supply. a. The U.S. gross domestic product falls. b. The level of prices in Korea falls. c. Labor receives a large wage increase. d. Economists predict higher prices next year.

Short answer

Question: Considering the four events (U.S. GDP falls, price level in Korea falls, large wage increase, and higher predicted prices next year), explain the overall effect on Japan's aggregate demand and aggregate supply. Answer: The overall effect on Japan's aggregate demand and aggregate supply depends on the magnitude of each shift caused by the four events. U.S. GDP falling and price level in Korea falling both decrease aggregate demand, while the latter two events increase aggregate demand. On the other hand, the large wage increase has a mixed effect on aggregate supply, as it increases demand but also reduces supply due to higher production costs. The prediction of higher prices next year increases both demand and supply. Thus, depending on the magnitudes of these shifts, the overall effect on aggregate demand and supply could be either an increase or a decrease.

Step-by-step solution

Draw the aggregate demand and supply diagram

To begin, draw the aggregate demand (AD) curve, which is downward-sloping, and the aggregate supply (AS) curve, which is upward-sloping. Label the intersection of the AD and AS curves as the equilibrium point.

U.S. gross domestic product falls

When the U.S. GDP falls, it means that the U.S. is experiencing an economic slowdown. Since the U.S. is a major trade partner with Japan, this event will decrease Japan's exports, which in turn reduces aggregate demand. To represent this effect on the diagram, shift the AD curve to the left.

Price level in Korea falls

When the price level in Korea falls, Korean goods and services become relatively cheaper compared to those in Japan. As a result, consumers may shift their preferences to Korean goods, leading to a decrease in demand for Japanese goods. This will cause Japan's aggregate demand to decrease. On the diagram, shift the AD curve further left to represent this effect.

Labor receives a large wage increase

When labor receives a large wage increase, it leads to higher income for workers. This may cause increased consumption, which could result in higher aggregate demand. On the diagram, we can shift the AD curve to the right. However, a significant wage increase can also lead to higher production costs for firms, which could reduce aggregate supply. In this case, shift the AS curve to the left on the diagram.

Economists predict higher prices next year

If economists predict higher prices next year, consumers may increase their spending now to avoid higher prices later, leading to an increase in aggregate demand. Shift the AD curve to the right on the diagram. At the same time, firms may decide to increase production in anticipation of higher demand, which would lead to an increase in aggregate supply. In this case, shift the AS curve to the right as well.

Combine the effects to show the final diagram

Show the cumulative effects of all four events on the aggregate demand and supply diagram. In this case, the overall effect depends on the magnitude of each shift of the AD and AS curves. Analyze the direction of the shifts to determine whether overall aggregate demand and supply have increased or decreased. Depending on the specific magnitudes, the new equilibrium point will either be to the left (decreased demand and supply) or to the right (increased demand and supply) of the original equilibrium point.

Key concepts

U.S. Gross Domestic Product

Understanding the U.S. gross domestic product (GDP) is crucial for analyzing economic health and its effects on global markets. GDP represents the total dollar value of all goods and services produced over a specific time period within the United States. It is an important indicator of the country's economic performance.

When the U.S. GDP falls, it indicates a slowdown in economic activity. This has direct implications for trade partners, such as Japan. A decrease in U.S. consumption can lead to reduced demand for exports from Japan, as American buyers may have less income to spend on foreign products. In such a scenario, the aggregate demand (AD) in Japan would decline, shifting the AD curve leftward on an aggregate demand and supply diagram. This shift reflects a drop in the overall demand for Japanese goods and services.

An economist would illustrate these changes by drawing the initial AD curve and then showing its leftward shift. In practical terms, Japanese businesses might experience a lower volume of sales, which can lead to a contraction in their economy if the United States is a significant trade partner.

Price Level in Korea

Price levels in a country indicate the average of current prices across the entire spectrum of goods and services produced in the economy. In Korea, if the price level falls, Korean products become cheaper relative to those of neighboring countries, such as Japan.

For Japan, the implication of a drop in Korea's price level is straightforward: cheaper Korean goods may attract consumers, both within Korea and internationally, to choose Korean products over Japanese ones. This substitution effect causes a decrease in aggregate demand for Japanese goods. Economists representing this would shift the Japanese AD curve leftward.

Incorporating economic predictions into real-world strategies, businesses might consider diversifying markets or improving competitiveness through innovation or cost-cutting measures. All these potential changes underscore why keeping an eye on regional price levels is vital for maintaining a stable economy in a closely connected global marketplace.

Labor Wage Increase

Wage levels are a fundamental element of an economy, as they affect both consumer spending and business production costs. A large wage increase for labor signifies that workers have more income, potentially leading to increased consumption and demand for goods and services. This boost in consumers' purchasing power would typically shift the AD curve to the right.

However, the story doesn't end there. Higher wages also mean increased costs for businesses that could cut into their profits unless they raise prices. If businesses face higher costs without an equivalent increase in productivity, the aggregate supply (AS) curve may shift to the left.

Thus, an economist analyzing the impact of wage increases must consider both the potential increase in AD due to higher spending by workers and the potential decrease in AS due to higher business costs. The net effect on the economy depends on the balance between these two opposing forces.

Economic Predictions

Economic predictions have a profound impact on consumer and producer behaviors. When economists predict higher prices in the future, it can lead to immediate increases in spending as consumers try to purchase goods before prices go up. This anticipatory behavior can lead to a rightward shift in the AD curve, as overall demand for goods and services increases.

Similarly, firms might increase production to capitalize on expected higher future demand, shifting the AS curve rightward as well. These shifts demonstrate the powerful role expectations play in economics, often termed 'animal spirits' by Keynesian economists. By understanding these dynamics, businesses and policymakers can better adapt to the future and make informed decisions that help stabilize and grow the economy.

While predictions can be uncertain, they are essential for strategic planning. Companies may build up inventories, and governments may adjust fiscal and monetary policies in anticipation of changing economic conditions. These proactive measures can help mitigate potential issues that arise from predicted economic shifts.
