I confirm that I have reviewed and complied with the relevant Instructions to Authors and the Authors’ Responsibilities defined in the Editorial Policy. I am also aware of the publisher’s retraction policy. All persons who meet authorship criteria are listed as authors, and all authors certify that they have participated sufficiently in the work to take public responsibility for the content, including participation in the concept, design, analysis, writing, or revision of the manuscript. Furthermore, each author certifies that this material or similar material has not been and will not be submitted to or published in any other publication before its appearance in the Journal of Contemporary Economics.


CRediT (Contributor Roles Taxonomy) was introduced with the intention of recognizing individual author contributions, reducing authorship disputes and facilitating collaboration. The idea came about following a 2012 collaborative workshop led by Harvard University and the Wellcome Trust, with input from researchers, the International Committee of Medical Journal Editors (ICMJE) and publishers, including Elsevier, represented by Cell Press.

CRediT offers authors the opportunity to share an accurate and detailed description of their diverse contributions to the published work.

• The corresponding author is responsible for ensuring that the descriptions are accurate and agreed by all authors.
• The role(s) of all authors should be listed, using the relevant above categories.
• Authors may have contributed in multiple roles.
• CRediT in no way changes the journal’s criteria to qualify for authorship.
