The International Monetary Fund (IMF) has been publishing, since 2017, a regular survey on macroprudential policy measures (IMF 2018), which can be a good starting point for empirical work. Second, in order to assess the effects of financial education, it is sufficient to link education received by an individual to outcomes at the individual level.
Assessing the effects of financial stability policies, in contrast, requires linking interventions that affect decisions at the micro-level to aggregate outcomes. Focusing on the big picture and on the question of how micro-incentives and decisions add up to aggregate behaviour is thus needed.
