Abstract
The Japanese economy is on the edge of collapse, so revision from a long-term perspective requires. However, in formulating specific economic policies, each ministry and agency prepare its own short-term, medium-term, and long-term economic forecasts for its own purposes. Therefore the numbers could be more consistent. For example, the MHLW presumably estimates the long-term GDP optimistically, expecting a rise in productivity, but the labour input as another factor for GDP determinant should be discussed seriously. For this reason, it may be time to prepare economic forecasts that ensure consistency over the short, medium, and long term, present a total package of economic policies and stimulate public debate.
