Following growing amounts of incoming donations exceeding seven digits in 2013 as recently reported,[49] the Foundation has reached a threshold of assets which qualify its consideration under the principles of industrial organization economics to indicate the need for the re-investment of donations into the internal research and development of the Foundation.[272] Two of the recent projects of such internal research and development have been the creation of a Visual Editor and a largely under-utilized "Thank" tab which were developed to ameliorate issues of editor attrition, which have met with limited success.[49][255] The estimates for reinvestment by industrial organizations into internal research and development was studied by Adam Jaffe, who recorded that the range of 4% to 25% annually was to be recommended, with high-end technology requiring the higher level of support for internal reinvestment.[273] At the 2013 level of contributions for Wikimedia presently documented as 45 million dollars, the computed budget level recommended by Jaffe and Caballero for reinvestment into internal research and development is between 1.8 million and 11.3 million dollars annually.[273] In 2016, the level of contributions were reported by Bloomberg News as being at $77 million annually, updating the Jaffe estimates for the higher level of support to between $3.08 million and $19.2 million annually.[273]
