Hours and income dynamics during the Covid-19 pandemic: The case of the Netherlands (with C. Zimpelmann, H.-M. von Gaudecker, L. Janys, B. Siflinger) forthcoming in Labour Economics

Using customized panel data spanning the entire year of 2020, we analyze the dynamics of working hours and household income across different stages of the Covid-19 pandemic. Similar to many other countries, during this period the Netherlands experienced a quick spread of the SARS-CoV-2 virus, adopted a set of fairly strict social distancing measures, gradually reopened, and imposed another lockdown to contain the second wave. We show that socio-economic status is strongly related to changes in working hours, especially when strict economic restrictions are in place. In contrast, household income is equally unaffected for all socio-economic groups. Examining the drivers of these observations, we find that pandemic-specific job characteristics (the ability to work from home and essential worker status) help explain the socio-economic gradient in total working hours. Household income is largely decoupled from shocks to working hours for employees. We provide suggestive evidence that large-scale labor hoarding schemes have helped insure employees against shocks to their employees.

Working Paper

Norm Prevalence and Interdependence: Evidence from a Large-Scale Historical Survey of German speaking Villages (with Paul Schäfer)

We use large-scale survey data of German speaking villages from the 1930's to investigate drivers of cooperation, gender, and religious norms. Through geographic cluster analysis, we show that inter-regional variation explains only little heterogeneity in norms. Villages in the same physical and institutional environment still maintain different norms. We argue that local differences in the structure of social relationships can explain intra-regional heterogeneity in norms. We focus on a community's ability to transmit and enforce norms to derive theoretical links between correlates of community social relationships and the number of norms it maintains (norm prevalence). Empirically we find that: (1) norm prevalence is positively related to three correlates of community social relationships: religiously homogeneous villages, villages that border on other villages with a different majority religion, and villages with more within-village social gatherings; (2) villages with stronger community-level social relationships are also less likely to segment their reference group for the cooperation norm to smaller social units; (3) cooperation norms make other norms more likely.
