Pandemic knowledge and regulation effectiveness: Evidence from COVID-19.

The spread of COVID-19 led countries around the world to adopt lockdown measures of varying stringency, with the purpose of restricting the movement of people. However, the effectiveness of these measures on mobility has been markedly different. Employing a difference-in-differences design, we analyse the effectiveness of movement restrictions across different countries.

The 'Great Lockdown' and its determinants.

Since COVID-19 was declared a pandemic, countries on the same pandemic trajectory have adopted very different lockdown strategies. Using data for over 132 countries, and employing an event-study design, this paper identifies the role of political, economic and institutional factors in explaining the differential timing and intensity of stringency measures undertaken.
