Lockdown policies and the dynamics of the first wave of the Sars-CoV-2 pandemic in Europe

This paper follows European countries as they struggled through the first wave of the Sars-CoV-2 pandemic. We analyze when countries were confronted with the virus, how long it took until the number of new infections peaked and at what level of infections that peak was achieved via social distancing and lockdown policies. Most European countries were able to successfully end the first wave of the pandemic–defined as a two-week incidence rate smaller than 10 cases per 100,000 people. We find that countries in which the virus made significant landfall later in time enjoyed a latecomer advantage that some of these countries squandered, however, by not responding quickly enough and that an early lockdown was more effective than a hard lockdown.
