The head of Angela Merkel’s Chancellery has warned that people’s behavior this weekend will be pivotal in determining whether strict shelter-in-place curfews are imposed in Germany to control the spread of the coronavirus.

Helge Braun, 47, Chancellor Angela Merkel's chief of staff, speaks with DER SPIEGEL about the rapidly rising number of coronavirus infections and about whether more stringent measures will have to be implemented.

The German health-care system is considered one of the best in the world. But the coronavirus is mercilessly exposing its weaknesses, with some hospitals already facing difficulties. Can Germany prevent the kind of collapse seen in Italy?

Germany's federal and state governments have agreed to further tighten restrictions on public life. Here's an overview of what's now allowed and what's not.

The German cabinet on Monday agreed to an unprecedented aid package to prop up the country's economy as the coronavirus pandemic takes hold. Parliament is set to approve the package later this week.

A railgun is an experimental weapon that uses electricity instead of explosives to fire long-range projectiles. In a railgun, a conductive projectile is propelled electromagnetically along two parallel rails. Though the device uses a tremendous amount of energy, it can launch objects hundreds of miles at many times the speed of sound. Both the US and Britain have developed and fired experimental models. What are the advantages and disadvantages of railguns compared to traditional guns?

The February Revolution was the first of two revolutions in Russia in 1917. Though spontaneous and poorly organized, the revolution resulted in the abdication of Tsar Nicholas II, the end of the Romanov dynasty, and the start of a new, provisional government. It resulted from a number of factors—low confidence in the monarchy, a looming famine, and a series of failures in World War I, which Russia was ill-equipped to fight. How did Rasputin help to spur the revolution, even though he was dead? Discuss

We study the impact of non-pharmaceutical policy interventions (NPIs) like “stay-at-home” orders on the spread of infectious disease. NPIs are associated with slower growth of Covid-19 cases. NPIs “spillover” into other jurisdictions. NPIs are not associated with significantly worse economic outcomes measured by job losses. Job losses have been no higher in US states that implemented “stay-at-home” during the Covid-19 pandemic than in states that did not have “stay-at-home”. All of these results demonstrate that the Covid-19 pandemic is a common economic and public health shock. The tradeoff between the economy and public health today depends strongly on what is happening elsewhere. This underscores the importance of coordinated economic and public health responses.

Ambient pollution is a byproduct of economic activity. It has been widely reported that COVID-19 and associated lockdowns have generated large improvements in air quality worldwide, including to China's notoriously-poor air quality. We analyze China's official pollution monitor data and account for the large, recurrent improvement in air quality following Lunar New Year (LNY), which essentially coincided with lockdowns in 2020. With the important exception of NO2, China's air quality improvements in 2020 are smaller than we should expect near the pandemic's epicenter: Hubei province. Compared with LNY improvements experienced in 2018 and 2019 in Hubei, we see smaller improvements in SO2 while ozone concentrations increased in both relative and absolute terms (roughly doubling). Similar patterns are found for the six provinces neighboring Hubei. We conclude that whether COVID-19 actually decreased pollution in China depends on the pollutant and reference period considered.

We conducted a large-scale survey covering 58 countries and over 100,000 respondents between late March and early April 2020 to study beliefs and attitudes towards citizens’ and governments’ responses to the COVID-19 pandemic. Most respondents reacted strongly to the crisis: they report engaging in social distancing and hygiene behaviors, and believe that strong policy measures, such as shop closures and curfews, are necessary. They also believe that their government and their country’s citizens are not doing enough and underestimate the degree to which others in their country support strong behavioral and policy responses to the pandemic. The perception of a weak government and public response is associated with higher levels of worries and depression. Using both cross-country panel data and an event-study, we additionally show that strong government reactions correct misperceptions, and reduce worries and depression. Our findings highlight that policy-makers not only need to consider how their decisions affect the spread of COVID-19, but also how such choices influence the mental health of their population.

Do new societal needs increase charitable giving or simply reallocate a fixed supply of donations? We study this question using IRS datasets and the natural experiment of deadly tornadoes. Among ZIP Codes located more than 20 miles away from a tornado's path, donations by households increase by over $1 million per tornado fatality. We find no negative effects on charities located in these ZIP Codes, with a bootstrapped confidence interval that rejects substitution rates above 16 percent. The results imply that giving to one cause need not come at the expense of another.

Despite widespread interest, there is little systematic evidence on the relationship between income, wealth, and charitable giving. We use the Panel Study of Income Dynamics to provide descriptive statistics on this relationship. We find that, irrespective of specifica­tion, donative behavior increases with greater resources.

We explored two measures of inequality that described the full income distribution in cities. One measure is an income gini based on family incomes in 1929 for 33 cities and in 1933 for up to 48 cities in 1933 were spread throughout the country. We also estimated gini coefficients that made use of contract rents for renters and implicit rents for home owners for up to 955 cities throughout the country. We were able to expand to all counties when looking at a top-end inequality measure, the number of taxpayers per family. All three measures varied substantially across the country. We show the correlations between the various measures and also estimate the relationship between the measures and various relief programs developed by governments at all levels during the period.

Many countries in Eastern Europe are taking drastic measures to slow the spread of COVID-19 -- in part because their health-care systems may not be up to the task.

With the wave of coronavirus infections washing over Europe, countries have turned inward to protect themselves. European Commission President Ursula von der Leyen has struggled to define the EU's role in the crisis as border checks have been reintroduced across the Continent.

Family members aren't allowed into hospitals nor can they take part in funerals. Crematoriums are overloaded. The horrors of coronavirus still have a firm hold on northern Italy.

The European Commission is limited in what it can do to combat the spread of the SARS-CoV-2 virus, but this only makes it more imperative for Brussels to set the correct priorities.
