The question then arises about policy responses. There are several
ways to classify these responses. Goyal and Howlett (2021) divided
them into 16 groups: curfew and lockdown, border restriction,
quarantine and tracing, government services, information
management, (non)essential business, testing and treatment, public
gathering, education, physical distancing, funding and stimulus,
advisory and warning, protective equipment, public event, health
screening, health resources. It can be seen that M. Howlett et al. have
adopted a broad concept in the evaluating policy responses, including
those aimed at stimulate economic growth and social propaganda. G.
Capano et al. classified different policies into 18 groups: tax payment
deferral, tax regulation relaxation, business loan, leave and
underemployment, travel advisory and restriction, social distancing,
monetary policy, health facilities, medical supplies, social security,
immunization and treatment, patient care, information and advice,
support for the vulnerable, school and university closure, COVID-19
epidemiology, financing relief, health-care spending. G. Capano et al.
have chosen an even border concept in defining the policy responses
for COVID-19, including epidemiology research and financing. In the
‘CoronaNet’ research project, researchers classified policies into 6
different categories, which are business restrictions, health resources,
health monitoring, school restrictions, mask policies, and social
distancing. The classification is rather rough but easy to manage for
such a sizeable project like ‘CoronaNet’.
This article would follow the classification peovided by T. Hale,
N. Angrist et al., which is as follows: school closure, workplace closure,
cancel public event, restriction on gathering, closed public transport,
public information campaigns, stay-at-home, restriction on internal
movement, international travel control, testing policy, contract tracing,
face covering, vaccination policy. These policies are specific and easy
to measure and can be assigned to a index to measure stringency of
each.
The point in time chosen for sampling in this research was mid-
March 2020, when all countries were just beginning to take action
