Research questions
How does the labour market react during financial crises and other downturns?
Are labour market reactions to financial crises systematically different from normal downturns?
Unemployment, employment and outputHysteresis and long-term unemployment
Wages and wage rigidityEmployment and output effects
2010
Overall evaluation
Lots of interesting charts and empirical analyses
Cover a broad range of important issues Provides a useful overview of labour
market reactions in downturns
Does not ”dig deep” on any specific issueOften low statistical significanceLittle analysis of heterogeneity and mechanisms

Wage equation

Wage equation
No wage share term – in contrast to theory and to a wealth of evidence on time series and panel data
Blanchflower & Oswald (1994), Nymoen & Rødseth (2003), Holden & Nymoen (2002), Forslund, Gottfries & Westermark (2008), Bårdsen & Nymoen (2009) ……….

Surprising that employment is not found to affect compensation – in contrast to most empirical studies
2010
”Compensation shocks lower employment growth, but regarding output and prices, the demand effect from higher wages seems to prevail and push up both.”

• Confidence bands in crises
2010
• Confidence bands in crises• “The impact on nominal growth rates however exceeds the output
effect. As a result, employment growth drops remarkably and eventually turns negative. “
2010
• Real compensation (?) and unemployment – two changes at the same time make it hard to interpret the results• How to interpret effect on unemployment?

“At the same time, note that there are several
countries where the real product wage had fallen
below 2008Q1 level already prior to 2009Q1. This is
in contrast to the ERM II crisis, where the real wage
shows far more inertia. In fact, the real wage shows
a countercyclical pattern in the large majority of the
countries during the ERM II crisis. This leads us to
conjecture that nominal wage inertia is less
prevalent during the current crisis.”
