Impact of the crisis and the 2020-2021 budget measures on firms (with Laurent Bach, Arthur Guillouzouic & Clément Malgouyres)

Published:

Using high-frequency VAT data, we find that the corporate sales impact of the Covid-19 shock in the spring of 2020 was very heterogeneous both between and within sectors. Emergency subsidies (loan guarantees, short-time work) do target firms with the biggest sales drops, albeit not perfectly. Corporate tax cuts, on the other hand, do not provide significantly more help to firms more affected by the pandemic. More info here

Will French companies be able to repay their state-backed loans (PGEs)? (with Laurent Bach, Arthur Guillouzouic and Clément Malgouyres)

Published:

Using new registry data for firms ending their fiscal year in mid-2020, we document the take-up by French firms of the Prêts garantis par l’État (PGE, the French iteration of the pandemic loans). The PGEs were very popular with French companies in 2020, including among the largest companies. The analysis of corporate balance sheets indicates, as one would expect, that the gross debt of the beneficiaries has risen sharply. However, this was not actually accompanied by an increase in net debt to alarming levels because some recipients received other grants, and others were only using the PGE scheme as a precautionary measure.

Micro-econometric evaluation of the THD Plan (Fast-Speed Internet) (with Paul Dutronc-Postel, Arthur Guillouzouic, Clément Malgouyres)

Published:

This analysis is based on micro-econometric tools that aim to estimate the causal effect of the installation of HSBB in a zone defined at a fine level (alternatively the commune and the cadastral parcel), by comparing it with other similar zones not benefiting from HSBB at that time. In particular, by comparing these two types of area before and after the arrival of THD, we can quantify the effect of this event.More info here
