The purpose of the study is to study time variations in 2016-2021 of the distribution of countries on the plane of "rectified" economic indices {s,r}. The index r ("Productivity") is related to the value of GDP per capita. The index s is related to the well-known Corruption Perceptions Index CPI. It was revealed that the parameters of the linear regression equation between the "rectified" indices s and r (including the coefficient of determination R2) change little from year to year. The temporal stability of the linear regression parameters between s and r was also found in certain parts of the productivity axis r, for example, for the fifty most productive countries. It was found that for about seventy of the least productive countries, the correlation between the "rectified" indices s and r is insignificant (the coefficients of determination R2 are small). The scientific novelty lies in identifying these statistical characteristics of the distribution of countries on the plane of "rectified" economic indices and in an attempt to estimate their time dynamics, as a result, the presented data make it possible to identify a measure of some global stability of the world economy in the considered time period, they also allow us to suggest the possibility of significant errors in statistical data for countries with a high level of corruption (small values of the index s) and low productivity (small values of the index r).
