Economic forecasting is the process of making predictions about the economy. Forecasts can be carried out at a high level of aggregation—for example for GDP, inflation, unemployment or the fiscal deficit—or at a more disaggregated level, for specific sectors of the economy or even specific firms.
Many institutions engage in forecasting, including international organisations such as the IMF, World Bank and the OECD, national governments and central banks, and private sector entities, be they think tanks, banks or others. Some forecasts are produced annually, but many are updated more frequently.
The Economic Outlook is the OECD’s twice-yearly analysis of the major economic trends and prospects for the next two years. Information on their forecasting methods and analytical tools and sources and methods is available online.
In early 2014 the OECD carried out a self-analysis of its projections in OECD forecasts during and after the financial crisis: a post mortem. "The OECD also found that it was too optimistic for countries that were most open to trade and foreign finance, that had the most tightly regulated markets and weak banking systems" according to the Financial Times.
The World Bank model is available for individuals and organizations to run their own simulations and forecasts using its iSimulate platform.
FocusEconomics and Consensus Economics Inc., among others, compile the macroeconomic forecasts prepared by a variety of forecasters, and publishes them every month. The Economist magazine regularly provides such a snapshot as well, for a broad range of countries (a recent example is provided here).
There are a lot of studies completed on the subject of forecast accuracy. Accuracy is one of the main, if not the main criteria, used to judge forecast quality. Some of the references below relate to academic studies of forecast accuracies.
The financial and economic crisis that erupted in 2007—arguably the worst since the Great Depression of the 1930s—was not foreseen by most of the forecasters, even if a few lone analysts had been crying wolf for some time (for example, Nouriel Roubini and Robert Shiller). The failure to forecast the "Great Recession" has caused a lot of soul searching in the profession. The Queen of England herself asked why had nobody noticed that the credit crunch was on its way, and a group of economists—experts from business, the City, its regulators, academia, and government—tried to explain in a letter.
