“…(2) where y ln( ) ismt is the outcome for municipality i, month ∈ m {1, …, 8}, sector s and year ∈ t {2017, 2018, 2019, 2020}; α i is a municipality fixed effect; γ s is a sector fixed effect; λ m is a month fixed effect; and ε ismt is an error term. The indicator variables are Y2020 for the year 2020, ∈ i , {1, …, 308} Bertrand et al, 2004). 15 When we estimate (1) for a single sector, we omit the corresponding fixed effect.…”
