Tables and figures must be labelled with a clear description of their contents. If applicable, a brief explanation of the symbols used (regardless of their detailed explanation in the text) and of the notes added or taken over by the author must be placed directly below the figure.

Tables and figures must be numbered consecutively in Arabic numerals (1, 2, 3, etc.). Each table and figure must be referenced in the text using the number (e.g. "Table 2 summarises the state of research on financial incentives").
