Journals are nowadays fairly open to preprints before submission (e.g. Nature policies here https://www.nature.com/nature-portfolio/editorial-policies/preprints-and-conference-proceedings). However, are they okay with institutional working papers?
For example, can I publish my work as an IMF or World Bank working paper and then submit the manuscript to a journal? I would some substantial change text and figures to fit scope but the results would be based on the same work (data + code).
