We conducted an experiment in which we hired workers under different types of contracts to evaluate how flexible working time affects on-the-job productivity in a routine job. Our approach breaks down the global impact on productivity into sorting and behavioral effects. We find that all forms...

In this paper we investigate the recent fall in unemployment, and the rise in part-time work and labour market participation amongst prime-aged Germans. We show that unemployment fell because the Hartz reforms induced a large fraction of the long-term unemployed to deregister as jobseekers....

We investigate the impact on work absence of a massive reduction in paid sick leave benefits. We exploit a policy change that only affected public sector workers in Spain and compare changes in the number and length of spells they take relative to unaffected private sector workers. Our results...

This paper investigates the short-run impact of public insurance expansion under the Affordable Care Act on out-of-pocket medical spending (OOP) and risk exposure among low-income, eligible households as well as the incidence of the cost of providing insurance. Using data from the Medical...

We present real time survey evidence from the UK, US and Germany showing that the labor market impacts of COVID-19 differ considerably across countries. Employees in Germany, which has a well-established short-time work scheme, are substantially less likely to be affected by the crisis. Within...

This paper uses administrative employer-employee data to uncover the effects of a large payroll tax reduction for minimum-wage workers in France. Exploiting the change in labor costs both at the job level and at the firm level, I find that the policy spurred an additional 13 percentage points...

We use population-wide tax register data to document the impact of the COVID-19 pandemic on firm sales, tax revenues, and sick pay in Sweden. The pandemic impact is identified using within-year, between-year, and geographical variation, and our data allows us to run placebo tests. Our findings...

In this paper we study the effects on the survival rate in employment of a scheme that facilitates gradual retirement through working time reductions. We use information on the entire labour market career and other observables to control for selection and take dynamic treatment assignment into...

We provide new insights regarding the finding that Medicaid increased emergency department (ED) use from the Oregon experiment. We find meaningful heterogeneous impacts of Medicaid on ED use using causal machine learning methods. The treatment effect distribution is widely dispersed, and the...

The trade war initiated by the Trump administration is the largest since the US imposed the Smoot-Hawley tariffs in the 1930s and was still raging when he left office. We analyze how the trade war impacted the 2020 US Presidential election. Our results highlight the political salience of the...
