Due to problems with the data I am temporarily retracting this study. Thanks to Pierre de Villiers from AOSIS for alerting me to the problem. In brief, for 2010 data I used original currency rather than USD. For this reason, for most publishers this data compares
apples and oranges. I will recalculate and re-publish in late March or early April.

<div>Abstract</div>
<div><br>
</div>
Most fully open access journals do not have publication charges. This study focuses on an update of a sample of 844 APC charging journals listed in DOAJ that were studied by Solomon and Björk in 2010. 98% of these journals are still active and 96% are confirmed
as still having publication charges. Pricing trends are diverse, with most journals showing little to no changes in price over 6 years with outliers showing a wide range from a price
<em>decrease</em> of $1,343 USD to a price <em>increase</em> of $1,844 USD. “Publisher” is a significant factor in trends at the p < .001 level, i.e. some publishers are raising prices on average (13 publishers have increased prices in the past 6 years by 100%
– 300% on average), others decreasing on average (19 publishers with lower prices in 2016 than 2010 on average). Limitations of the study: the original dataset was based on a sample of DOAJ journals charging APCs, and there is likely some conflation of pricing
trends and currency fluctuations. This dataset supports an hypothesis of ongoing volatility in the APC market as we originally noted in our 2014 survey (Morrison et al, 2015).
