Macroeconomic forecasting involves predicting the entire economy of a country or the world. It can be theoretical, empirical, or micro-founded, and aims to understand the effects of factors such as interest rates and taxation. Empirical forecasting involves examining past data, while micro-founded forecasting breaks down the economy into the smallest possible parts to predict the effects of a particular change.
Macroeconomic forecasting involves forecasting the entire economy of a country or even the world. Some of these forecasting techniques are described as empirical: they look at the past relationship between different economic data and assume that the same cause and effect pattern will continue. Other types of macroeconomic forecasting involve working on the assumption that everyone involved in an economy will make rational choices.
The purpose of macroeconomic forecasting is to look at an entire economy. This is in contrast to microeconomics, which looks at a particular market, such as how supply and demand affects the sales and price of widgets, or the job market for widget makers. Macroeconomics is more complicated as it involves not only many individual markets, but also the effects of factors such as interest rates and taxation.
The simplest type of macroeconomic forecasting is theoretical models. They work on basic rules that are believed to be true. For example, one such “rule” might be that if interest rates are cut in half, people’s disposable income will increase by 20 percent due to lower mortgage payments, and this will result in a 10 percent increase in sales of goods in the country. economy with prices that five percent. The two main drawbacks of such forecasting are that it is difficult to know how accurate the models are, and that the sheer complexity of a large economy can greatly exaggerate any inaccuracies in the model.
A more complicated variant of macroeconomic forecasting is known as empirical forecasting. This involves examining past data and drawing conclusions. For example, a forecaster might look at the changes in income taxes and changes in total purchases each year in the past and try to establish a common relationship. This will not necessarily be what one would expect from a purely theoretical perspective. This past relationship can then be applied to future predictions. Such models vary enormously in complexity depending on how much data is used and how many factors are taken into account.
Probably the most complicated type of macroeconomic forecasting are those classified as micro-founded, such as dynamic stochastic general equilibrium models. Microfounded forecasting involves breaking down the economy into the smallest possible parts, preferably for each person or organization that makes decisions, such as consumers deciding what to buy, producers deciding where to buy supplies, or governments deciding the level of tax on sales. The technique then involves establishing which decisions might best serve self-interest, whether that means consumers getting value for their money, producers seeking to increase profits, or governments seeking to maximize tax revenues without hurting the economy. Economists then build this into a complicated model that can predict the effects of a particular change when each side acts in the most rational way.
