The Cycle of Earnings Inequality: Evidence from Spanish Social Security Data
利用西班牙社会保障数据，研究了1988至2010年间男性收入不平等与就业的演变，发现不平等呈强逆周期，且与建筑业需求冲击密切相关。
We use detailed information from social security records to document the evolution of male earnings inequality and employment in Spain from 1988 to 2010. We find that inequality was strongly countercyclical: it increased around the 1993 recession, experienced a substantial decrease during the 1997–2007 expansion and then a sharp increase during the recent recession. This evolution went in parallel with the cyclicality of employment in the lower middle part of the wage distribution. Our findings highlight the importance of the housing boom and bust in this evolution, suggesting that demand shocks in the construction sector had large effects on aggregate labour market outcomes.
