MDPI 2019: price increases, some hefty, and more coming in July

In brief: MDPI has increased prices, in many cases quite substantially (some prices have more than tripled). Even more price increases are anticipated in July 2019, which will have the effect of doubling the average APC and tripling the most common APC. Unlike other publishers’ practices, there are no price decreases.

Comment and recommendation: open access advocates, along with policy makers and research funders, and keen to support a transition to open access. In my opinion, the enthusiasm of payers to support APC journals is causing an unhealthy and unsustainable distortion in the market. My advice: stick with green OA policy. Require deposit of funded works in an open access repository. This is a better means to ensure ongoing preservation and open access, and exerts market pressure in a way that is more suited to the development of an economically sustainable open access system.

Details

Details, data, and links to very raw data follow. Comments and math-checking are most welcome.

February 2018 to February 2019.

MDPI lists 203 journals as of February 13, 2019. Of these, since this time last year, 74 or 36% have either started charging APCs, or have increased their APCs by 7% – 227% or 100 CHF – 1,250 CHF. For example, the APC of Cells rose from 550 to 1,800 CHF, a 227% increase, that is, the price more than tripled. As of today, according to XE Currency Converter, the CHF is worth .99 of USD, or very close to par. 17 journals are new. MDPI had no price decreases in 2019.

February to July 2019

MDPI lists price changes coming in July 2019 on their website (kudos for transparency). 160 of MDPI’s journals (79% of their journals) will have a price change in July 2019, either introducing an APC for the first time or increasing in price by 9% – 243% or 100 – 850 CHF. The net effect is a doubling or tripling of central tendencies. The average APC doubles from 546 CHF to 1,077 CHF. The median or mid-point and mode or most common APC triples from 350 CHF to 1,000 CHF. These figures exclude “free” journals, which are currently the mode or most common price.

MDPI pricing (thanks to MDPI CEO Franck Vazquez, PhD)

Thanks to MDPI CEO Franck Vazquez, PhD, for permission to re-post his contributions to a discussion on APC pricing on the SCHOLCOMM listserv and my replies. This is useful information and a good model of how transparency can help to advance our understanding of how to move toward sustainability in open access.

Highlights: this post presents data on MDPI’s APCs and an explanation of MDPI’s business practice: new journals are free to publish in, later APCs and APC increases are based on market value. It is important for publishers and funders to understand that there is an essential conflict with funders of scholarly communication, that is, universities and their libraries, and research organizations. For these organizations,  budgets tend to be based on cost with little or no flexibility to accommodate pricing and price increases based on market value. This incompatibility of organizational strategy is equally relevant whether the revenue model is subscriptions, APC, or other production-based support.

My reply April 16, 2018

Thank you Franck this is very helpful.

According to this website, the current inflation rate for Switzerland is .8, i.e. less than one per cent:

I see that a quarter of MDPI’s journals have an average price increase of 27.3%. It appears that MDPI is not making decisions about price increases based on such factors as consumer price increase or inflation rates.

List members who are interested in supporting OA through paying APCs could benefit from understanding how this works in order to budget for future needs. Can you explain MDPI’s current and/or projected future pricing strategy?

MDPI is one of the publishers who offers “free for now” publishing in order to attract content for new journals. As an author, I have benefited from this as well as from MDPI’s high quality professional editing and peer review. However, if those who pay APCs do not take this practice into account, they will find themselves short of funds in future when established journals start charging APCs, as 10% of MDPI’s journals did this year by your account

Two other notes / questions from MDPI for this year that I wonder if you would like to comment on?

* new pricing coming in July
* partnership with Knowledge Unlatched – on MDPI’s APC price list that
some journals are
“* free for authors; APC funded by Knowledge Unlatched

Franck’s reply April 17:

Thanks Heather, I am glad you had a good experience publishing in /Publications/ (and /Data/)!

Our decision to introduce or increase the APC of a journal depends on many factors including the field of research, the reputation (visibility,citation, indexing), and volume (=age) of the journal. It is not always possible to cover the cost of our work directly and from the beginning. The newest journals are free for a few years, typically three years; researchers would not be able to raise funding to cover the APC of these journals. Also, some journals which support research fields in which OA funding remains marginal do not introduce an APC, even after Volume 6 or more, as it is the case for the journals /Publications/, /Arts/, or a few others. Therefore the costs associated with publishing in these journals must be subsided by the APC of established journals.

The “average 27.3% APC increase for 40 journals” we talk about here results in a mild increase in the average APC of these journals. Average increase is 219 CHF, from 802 CHF in 2017 to 1020 CHF in 2018 for these 40 titles. This is on the lower end of APC distribution for international publishers: https://treemaps.intact-project.org/apcdata/openapc/#publisher/

Concerning the planned increase in July:
Eight journals which were accepted for coverage in SCIE in November will have their APC increased, following the reasoning explained before. As usual we give a >6 months notice to authors before the APC increase becomes effective.

About the partnership with Knowledge Unlatched:
We are running this as a trial for 9 journals which normally apply the indicated APC. We are exploring this funding model as a viable alternative for our HSS journals. For transparency reasons and to give credit to KU for their initiative, we decided to list the APC on the website with the note “* free for authors; APC funded by Knowledge Unlatched” rather than erasing the APC from the website.

Best wishes
Franck


My reply April 17:

Thank you Franck.

What you are describing is normal business practice. In ordinary everyday terms, businesses of all kinds often start out with below-cost pricing (introductory special offers for example), in order to attract customers, then raise prices. When average people sell their homes or other goods, the default is to seek market value (the most I can get for this), rather than cost-based pricing.

MDPI’s transparency may be helpful to those wishing to support the APC approach (publishers and payers), as it gives us an opening to talk about an inherent conflict that might cause shock and setbacks, giving an opportunity to prepare and consider strategies to minimize or avoid the likelihood of this happening.

The inherent conflict stems from the desire of for-profit publishers to derive the maximum value from their work, in contrast to the cost-conscious, accountability focused customer (universities and funding agencies). In subscriptions publishing for many decades there has been an inelastic market, with publishers expecting to raise prices beyond inflationary rates year after year while university-customers do not have corresponding revenue growth to support this. In North America in the last few decades the trend has been flat or declining budgets. Hence the serials crisis, periodic breakdown such as Germany’s Elsevier cancellations and France’s Springer cancellations, and strong desire to change the system which is one of the drivers behind the OA movement, although not a motive shared by all.

What could easily happen is that those who wish to support a flip to OA via APCs will under-budget based on current spend and/or current list prices, resulting in shock and insufficient funds when publishers move to pricing more accurately reflecting costs and/or market value.

Another way to express this: when your library has to deal with budget cuts, or, at best, a flat budget (typical in North America), you are not likely to have much sympathy for a publisher raising prices by 27%, regardless of how rational this might be as a business practice.

This is what I mean in that Publications article when I describe the APC model as volatile. The market, in my opinion, is not sufficiently stable for systemic budgeting purposes. Support for this approach should be considered experimental at this time.

There are other approaches to supply-side funding to provide for open access, such as sponsorships, library publishing, and cost-based APC pricing as practiced by UK-based Ubiquity Press. Those who wish to support APCs, in my opinion, are wise to do so through consortia. Hence my interest in your partnership with Knowledge Unmatched.

MPDI : suivi des APCs

Résumé :

En comparant les frais de publication des différentes revues mentionnées sur le site MDPI entre mars 2016 et mars 2017 nous remarquons quelques différences entre les 2 années.

Ceci dit que les APCs ont augmenté dans 92 % des revues. Cette augmentation oscille entre 6% et 350 %.

Par exemple, les APCs pour la revue Coalitions est passé de 350 CHF en 2016 a 850 CHF en 2017.

Selon le site MDPI, environ 60 revues en libre accès n’exigent pas de frais de publication en 2017.

En observant de près les APCs des différentes revues, nous remarquons qu’il n’y a aucune baisse des frais de publication et que seulement 8% des revues ont gardé les mêmes frais de publication 2016-2017.

Comparaison DOAJ et MDPI : Titres et APC

Résumé :

En comparant les frais de publication mentionnés par DOAJ et ceux de l’éditeur lui-même (MDPI) nous avons remarqué quelques différences : Selon le site MDPI, environ 175 revues en libre accès sont listées contre seulement 146 dans DOAJ.

Par ailleurs, parmi la liste MDPI, 107 revues exigent des frais de publication alors que DOAJ n’en mentionne que 21. Aussi, aucun des frais de publication DOAJ n’est inférieur à celui mentionné par MDPI. Seulement 3 revues ont les mêmes frais. Dans 31 des cas étudiés, les frais MDPI sont plus élevés de 50% et plus que ceux fournis par DOAJ.  Applied Science, l’exemple de différence le plus frappant, passe de 500 CHF en DOAJ à 1200 CHF sur le site MDPI.

Objectif :

Cette étude se propose de comparer la liste des revues répertoriées par DOAJ versus l’éditeur lui-même ; MDPI en l’occurrence; ainsi que la différence des frais de publication mentionnés.

Méthodologie :

L’échantillon est constitué de 107 revues de l’éditeur MDPI.

Nous avons commencé par repêcher les frais de publication sur le site de DOAJ en janvier 2017. Par la suite, nous avons cherché les frais de publication pour ces mêmes revues sur le site de l’éditeur lui-même, MDPI en l’occurrence et ce en février 2017.

Les données sont consignées sur un document Excel pour pouvoir par la suite calculer la différence des APC.

Résultats

  1. Selon le site MDPI, environ 175 revues en libre accès sont listées ; seulement 147 de ces revues sont recensées en DOAJ.

En comparant les APC (frais de publication par l’auteur) des revues répertoriées, nous constatons que DOAJ ne recense pas (ou la liste n’est pas a  jour)toutes les revues en accès libre de l’éditeur MDPI ; seulement 147 sur 175 titres y sont listées. Les 28 revues manquantes a l’appel sont :

  1. Big Data and Cognitive Computing
  2. Biomimetics
  3. ChemEngineering
  4. Condensed Matter
  5. Cryptography
  6. Data
  7. Designs
  8. Drones
  9. Epigenomes
  10. Fermentation
  11. Fishes
  12. Genealogy
  13. Horticulturae
  14. Infrastructures
  15. Instruments
  16. International Journal of Turbomachine Propulsion and Power
  17. Journal of Functional Morphology and Kinesiology
  18. Languages
  19. Logistics
  20. Magnetochemistry
  21. Mathematical and Computational Applications
  22. Multimodal Technologies and Interactions
  23. Philosophies
  24. Recycling
  25. Scientia Pharmaceutica
  26. Sinusitis
  27. Tropical Medicine and Infectious Disease
  28. Vision

Il est à noter que la majorité de ces titres sont de nouvelles revues 2017. Une seule revue « Chromatography » est listée dans DOAJ mais pas sur le site MDPI.

2. Parmi la liste MDPI, 107 revues exigent des frais de publication (APC) seulement 21 ont des frais de publication selon DOAJ (environ 20 %).

3. Pour ces 20 % des revues, aucun APC DOAJ n’est inférieur à celui mentionné par MDPI

En observant les APC fournis par les deux sites, nous remarquons qu’aucun des APC n’a diminué entre janvier 2017 et février 2017.  Seulement 3 desdites revues ont les mêmes frais de publication dans les deux répertoires (lignes vertes), ceci dit environ 86% des APC sont différents.

Cette augmentation des APC oscille entre 7% et 140 %. L’APC de la revue Applied Sciences est de 500 CHF selon DOAJ versus 1200 CHF selon MDPI.

Conclusion

En guise de conclusion, les observations ci-dessus nous amènent à se poser une question : Est-ce que l’information fournie par DOAJ est mise a jour?

Les chiffres obtenus démontrent une grande différence non seulement au niveau de la liste des revues en libre accès mais aussi au niveau de l’information fournie aux auteurs, les frais de publication en particulier.
