Notes:

We identify the approach to solving the research problem: quantitative, qualitative, qualitative (systematic literature review) or mixed method;

We identify the research methodologies as archival methods – solve the research problem based on empirical data from primary or secondary sources;

The data source is classified as primary, secondary or both primary and secondary;

We clarify the research theme. We consider the theme as either behavioural (studies about human or organisational behaviour) or market-based (use capital market data and focus)
