Demand could be the answer, so what factors could affect the demand to increase or decrease.
Growth of Population in Japan - Rice production could not keep up with this increase. Lack of Raw Materials in Japan - Valuable commodities such as oil, rubber, iron had to be imported.
Changes in factors such as consumer income, preferences, prices of related goods, and expectations can shift a demand curve. An increase in consumer income or preferences for a product can shift the demand curve to the right, indicating higher demand. Conversely, a decrease in income or preferences can shift the demand curve to the left, indicating lower demand.
An increase in aggregate demand is not always desirable, as it can lead to inflation if the economy is already operating at or near full capacity. While higher demand can stimulate economic growth and reduce unemployment in the short term, it may also result in rising prices and potential overheating of the economy. Additionally, if the increase in demand is driven by unsustainable factors, such as excessive credit or government spending, it could lead to long-term economic instability. Thus, the effects of increased aggregate demand depend on the economic context and underlying conditions.
Complementary goods are consumed with other goods and the prices for these goods can affect demand for automobiles. These factors can include petrol prices, tyre prices or vehicle registration costs. In general, if any of these increase, their demand will decrease, along with demand for automobiles.Supplimentary goods are consumed instead of other goods, in other words, they are alternatives to a certain good. In this case, they could include bicycles, motorcycles, footpaths and public transport. If any of these goods increase in price, then automobiles will become more in demand due to being a cheaper alternative, whereas if the price of the goods decrease, demand for automobiles will likely decrease.
Higher interest rates mean that the demand for cars have increased, due to an increase in consumer demand. Lower interest rates mean that there is a lower demand and the FOMC is lowering the rates to increase consumer demand. Lower rates, however could also increase the demand for cars. This is why the Feds have to higher the interest rates, to ensure that the supply and demand are at an equilibrium point.
Factors that could potentially cause a shift of the aggregate demand curve to the left include a decrease in consumer confidence, higher interest rates, reduced government spending, and a decrease in exports.
an increase in demand for the good. Such as a successful marketing campaign for the good.
Increases in demand are shown by a shift to the right in the demand curve. This could be caused by a number of factors, including a rise in income, a rise in the price of a substitute or a fall in the price of a complement.
A complementary good. Substitute and complementary goods are determined by cross elasticity of demands. A substitute good has positive cross elasticity: the mercantile characteristics of this good increase if the same characteristic of a different good decreases. If the only two drinks in the world were orange juice and apple juice and the price of orange juice went up (causing concomitant reduction in demand for it), the demand for apple juice would increase. A complementary good has negative cross elasticity: the mercantile characteristics increase if the same characteristic of the complementary good also increases. Maybe if the demand for salami increased the demand for bread would also increase because most people who buy salami eat it on sandwiches. Obviously these are both classroom theoreticals because a lot of things go into determining demand for an item...the demand for salami could increase without a concomitant increase in demand for bread because people have found salami makes a great salad ingredient, or the demand for peanut butter could increase without a similar increase in jelly demand if everyone makes peanut butter cookies.
Change in demand is subjective, it could be increase or decrease in the qauntity of good or services asked for, while change in quantity demand is objective, it refers to actual quantity/amount of good or seevices requested /demanded .
Consumers want more and more goods and services. Stronger consumer demand for goods with a limited or fixed supply. A price level increase due to an increase in aggregate demand.
