EconPol Policy Briefs

Testing for Covid-19 is a bottleneck that we face in front of the pandemic. Test production is currently much below what is necessary for mass testing strategies which are required in order to control the pandemic while letting people go back to work. In this paper, Christian Gollier (EconPol Europe, Toulouse School of Economics University of Toulouse- Capitole) and Olivier Gossner (CNRS – CREST, Ecole Polytechnique, London School of Economics) show how group testing can be optimized in three applications to multiply the efficiency of tests against Covid-19: Estimating virus prevalence to measure the evolution of the pandemic; bringing negative groups back to work to exit the current lockdown; and testing for individual infectious status to treat sick people. 

António Afonso (EconPol Europe, Lisbon School of Economics and Management of the Universidade de Lisboa) has estimated the real growth rate of GDP in Portugal in 2020 and predicts a budget deficit of around 3% or 4% of GDP, implying a break and not a fiscal regime switch. Of particular relevance, he says, is private consumption and investment, with households cutting spending significantly and an increase in government spending necessary to cover the lack of domestic demand.

Wage smoothing is beneficial for firms and workers, but wage rigidities can lead to bilaterally inefficient separations. By comparing the impact of four policy measures regarding their impact on welfare, output and government expenditures, Martin Kerndler (TU Wien) and Michael Reiter (IHS Vienna, NYU Abu Dhabi, EconPol Europe) have identified a reasonable policy mix to counter the negative employment effects of wage rigidities. 
 

This EconPol policy brief, using figures from the ifo Institute, calculates potential costs of coronavirus to the German economy of up to 729 billion, with up to 1.8 million jobs cut and six million workers affected by lower hours - however it stresses that the aim of any action must be to shorten the partial shutdown of the economy without compromising the fight against the epidemic, with strategies that combine a resumption of production with further containment of the epidemic.

The rise of China in the world economy and its growing importance as investor in industrialised and developing countries has raised concerns of policy makers in some countries. Contrary to the trade situation between China and the US, trade between the euro area aggregate and China is almost balanced. On an individual country level, Germany, Ireland and Finland record trade surpluses with China. As trade between the euro area and China is balanced, there is no need for policy action to address any imbalance, however, European markets should only be opened for Chinese companies and investment if this is reciprocated.
