Mapping a causal scheme of indicators in the COVID-19 crisis

The COVID-19 crisis has been accompanied by an extensive use of indicators, such as those related to COVID infections and deaths, but also a good number of COVID policy indicators. This paper discusses these indicators from the perspective of a legal scholar with an interest (and some expertise) in comparative law and empirical legal studies. This means that this paper does not engage in the details concerning epidemiological and medical issues of COVID infections and deaths. Rather, it focuses on two main issues: first, it develops and maps a general causal scheme of indicators and their underlying real-world phenomena in the COVID crisis; second, it shows how such a causal scheme has been, and can be, applied in comparative empirical legal research. Yet, it also notes the difficulties of proving causal relationships and some attempts to overcome them.
