GDP is a vitally important economic indicator that is often critical in making important policy and business decisions which effect millions of people every day. However, correctly calculating GDP requires the detailed analysis of a huge quantity of statistical information, which means that a reliable calculation is usually not available until months after the fact. Often, the real GPD figure is quite different from the estimate used by economists and policy makers. Now-casting Economics ltd uses a highly sophisticated mathematical economic model to analyse a wide range of economic indicators and accurately `forecast` the current GDP statistics for multiple economies. Their model is based on the work of the foremost researchers who are pioneering this new field of economics. Their service is now available to subscribers.
