Simon Kuznets, an expert on national income statistics, argues that an average margin of error for national income estimates of about 10 percent is reasonable.5  Considering this, it makes no sense to state changes in GDP with an accuracy of 1/10 of one percent!

In the light of Morgenstern's analysis this is completely futile. Most of the time, economists tend to predict fiscal growth well. have the solution x = 100001, y = 100000, while the almost identical equations. There's not actually much evidence that polls are becoming less accurate. With all these difficulties in mind, would it not be very important, not to mention more honest, to provide an error estimate for national income statistics? Economics is a complex subject filled with a maze of confusing terms and details which can be difficult to explain. have the solution x = - 99999 y = -100000. In contrast to physics, there is still no estimate of statistical error within economics. Accurate economic research group using math derived from skull measurements sees slower recovery. America's Great Depression. Synonym Discussion of accurate. 2nd ed. Armstrong Economics is an economics blog that states its mission is “to research historical cyclical patterns and market behavior in timing, price and crisis to better understand and identify potential future trends, using an extensive monetary database and advanced proprietary models.
