The results identify two types of recessions: those driven by labour-aumenting efficiency—such as the fin de siècle Depression and the Great Depression—and those primarily shaped by the household labour wedge—namely, the Great Stagflation, European Recession, Great Recession, and the covid-19 crisis. Tax dynamics played a key role in the Great Stagflation, but not in the more recent crises. Openness and employment composition are informative about labour-aumenting efficiency trend, while institutional labour market features — such as temporary contracts and unemployment benefits — are closely linked to the household labour wedge. The analysis confirms the growing relevance of the household labour wedge in explaining macroeconomic fluctuations in Spain, even when accounting for a stochastic downward trend in hours worked.
