I would suggest that one could start with some reflections (e.g. involving a PhD or Master student, or a team of economics students) on systems thinking and economic theory. For example, one could reflect on
the various concepts that make up economic theory from the perspective of Biomatrix Systems Theory, as presented on www.biomatrixtheory.com and exemplified by the examples below on the law of diminishing returns and opportunity cost, economic growth and the market and financial paradigm.
the implication of the various concepts of Biomatrix Systems Theory for economic theory, as shown by the following examples of mei, limits, systemic governance the distinction between physical and conceptual reality.
The output from these two types of inquiries could reveal some patterns that can be explored further.
