Measuring labor supply and demand shocks during COVID-19.

Area of Science:

• Economics
• Labor Economics
• Macroeconomics

Background:

• The COVID-19 outbreak presented unprecedented challenges to labor markets globally.
• Understanding the drivers of labor market fluctuations during the pandemic is crucial for economic policy.
• Sector-specific impacts of the pandemic on labor demand and supply require detailed analysis.

Purpose of the Study:

• To quantify labor demand and supply shocks at the sector level during the initial phase of the COVID-19 outbreak.
• To determine the relative contributions of labor supply and demand shocks to the aggregate decline in hours worked.
• To validate the estimated labor supply shocks using alternative measures.

Main Methods:

• Employed a Bayesian structural vector autoregression (BVAR) model.
• Utilized monthly data on hours worked and real wages at the sector level.
• Correlated estimated supply shocks with sectoral teleworkability measures for validation.

Main Results:

• Most sectors experienced substantial negative labor demand and supply shocks in March and April 2020.
• Significant heterogeneity in shock magnitudes was observed across different economic sectors.
• Labor supply shocks explained approximately two-thirds of the aggregate decrease in hours worked.

Conclusions:

• The initial economic impact of COVID-19 on labor markets was significantly driven by supply-side disruptions.
• Sectoral differences in shock transmission highlight the varied effects of the pandemic.
• The correlation with teleworkability provides empirical support for the estimated labor supply shocks.
