Article processing charges (APCs) support peer review coordination, editorial management, production, DOI registration, and long term digital archiving. APCs are applied after acceptance and do not influence editorial decisions.

IJNR is committed to transparency and affordability for researchers who publish negative or null results.

• Editorial assessment and peer review management
• Copyediting, layout, and publication production
• DOI registration and metadata validation
• Long term archiving and platform maintenance
• Open access hosting and global dissemination

Authors from World Bank classified low income and lower middle income countries may be eligible for partial APC waivers. Requests are evaluated on a case by case basis and must be submitted before acceptance.

Membership options offer discounted APCs for eligible authors and institutions. Contact the editorial office for guidance.
