One of the most important indicators of the visibility and engagement of a scientific journal is its citation impact factor, as calculated and published by Thomson-Reuters.
There are two-year and five-year citation impact factors. The two-year impact factor for 2016 is calculated by looking at all the citations in 2016, from all Thomson-Reuters listed journals in all disciplines, of articles published in JOIE in 2014 and 2015. This number of 2016 citations is then divided by the total number of articles published in JOIE in 2014 and 2015.
The 2016 five-year impact factor is similarly calculated, by addressing all articles published in JOIE in the period 2011-2015.
The 2016 Impact Factor for JOIE is 0.794 and the journal currently ranks 194th out of 347 journals in the Economics JCR in Thomson Reuters. This is a small decrease on the 2015 Impact Factor of 0.939 when the journal was ranked 154th out of 344 journals. It is really encouraging to see that although the Impact Factor has fallen, JOIE has received an increased number of citations as well as an improvement in the 5-year Impact Factor.
JOIE also received a 5-year impact factor of 1.106 in 2016. This is the first time that either Impact Factor has exceeded 1.000 and it is a great indication of the rising levels of citation to JOIE.
