Commute-Zone Micro-Market Tightness Granularity
Observational StudyClinical Trial
Measuring labor market tightness at broad national or regional levels masks localized disparities in vacancy-to-unemployment ratios across specific industry sectors and commuting zones.
Picture this
Checking the average temperature of an entire country provides little useful detail; measuring temperature room by room across individual houses gives an accurate climate map for every neighborhood.
What the evidence says
The distribution of granular micro-market tightness yielded a median value of 0.35 across experimental firm locations, matching national macroeconomic slackness while enabling fine-grained subgroup treatment evaluations.
- Who was studied
- N = 322 commute zones (`zone d'emploi`) across mainland France combined with 74 NAF industrial sector categories.
- How
- Micro-market level aggregation measuring vacancy-to-unemployed ratios within commuting zone by sector cells.
What to do
Calculate labor market tightness at the intersection of commuting zone and industrial sector to capture localized supply-demand frictions.
From the source
"We calculate tightness again at the micro-market level (commute-zone x sector) to obtain a more granular indicator of the labor market conditions faced by sample firms at the beginning of the intervention."
