Pandemic Inflation: What Labour-Force Participation Revealed

Q1. What did the first two quarters of 2020 reveal about the apparent unemployment gap during the pandemic shock?
- It appeared negative because unemployment rose while labour-force participation fell
- It became strongly positive because participation increased
- It was unchanged because unemployment did not move
- It disappeared because inflation stopped responding to labour-market conditions
Answer: It appeared negative because unemployment rose while labour-force participation fell. The fall in participation made the observed unemployment rate understate the deterioration in available labour, making the unemployment gap misleadingly negative.
Q2. What is the participation gap intended to capture in analysing pandemic labour-market slack?
- The gap created by people leaving or not entering the labour force
- The difference between consumer and producer prices
- The gap between short-run and long-run inflation
- The difference between employment in the USA and the euro area
Answer: The gap created by people leaving or not entering the labour force. It accounts for labour-market slack hidden by the decline in participation, rather than relying only on the unemployment rate.
Q3. According to the article's estimate, how much higher would inflation have been absent the pandemic-related participation decline?
- About 0.4 percentage points
- About 0.04 percentage points
- About 4 percentage points
- About 40 percentage points
Answer: About 0.4 percentage points. The estimate indicates that accounting for the participation shortfall materially changes the inferred inflation pressure.
Q4. Why did the unemployment-only Phillips curve give a misleading reading of inflation pressure during the pandemic?
- It omitted slack associated with the participation decline
- It included too many measures of labour supply
- It treated inflation as unrelated to unemployment
- It measured participation but not unemployment
Answer: It omitted slack associated with the participation decline. An unemployment-only curve could miss labour-market slack when people leave the labour force, whereas an augmented curve adds participation information.
Q5. How does an augmented Phillips curve differ from an unemployment-only Phillips curve in this context?
- It includes a participation-gap measure alongside the unemployment gap
- It replaces inflation with the participation rate
- It excludes unemployment from the analysis
- It assumes labour supply did not change
Answer: It includes a participation-gap measure alongside the unemployment gap. The augmented specification reflects both observed unemployment and the labour supply withdrawn from the market, producing a different assessment of pandemic inflation pressure.
