A forecast is a prediction of economic conditions. It is based on a number of factors, such as inflation, interest rates, unemployment, and production. These factors can be affected by a variety of events, such as natural disasters or political unrest. Forecasting helps businesses make informed decisions that can increase their profits.
For example, when an employee in a manufacturing company sees that sales are likely to rise, the business may purchase more materials to prepare for increased orders. This can help lower costs as the company doesn’t waste resources on excess inventory. Forecasting also helps businesses learn from past mistakes by studying data from previous years. This can allow companies to avoid making the same errors.
Many of these predictions are made using complex mathematical models. However, even these models have limitations. For example, they are generally not capable of predicting a sudden change in the economy such as a recession. In addition, some models require forecasters to input their own beliefs or assumptions, which can lead to subjective or biased projections.
McCracken said that forecasts are often influenced by the type of economic theory the forecaster believes in. For instance, if a forecaster believes that the economy is determined by the supply of money, they might tend to pay more attention to financial series like stock market prices. In contrast, if a forecaster believes that hefty government spending is bad for the economy, they might tend to focus on labor-force data such as unemployment rates.
