In this paper, we describe a computational implementation of the Synthetic difference-in-differences (SDID) estimator of Arkhangelsky et al. (2021) for Stata. Synthetic difference-in-differences can be used in a wide class of circumstances where treatment effects on some particular policy or...

On March 19, 2020, California Governor Gavin Newsom issued Executive Order N-33-20 2020, which required all residents of the state of California to shelter in place for all but essential activities such as grocery shopping, retrieving prescriptions from a pharmacy, or caring for relatives. This...

Both the White House and state governors have explicitly linked thresholds of reduced COVID-19 case growth to the lifting of statewide shelter-in-place orders (SIPOs). This "hardwired" policy endogeneity creates empirical challenges in credibly isolating the causal effect of lifting a statewide...

We evaluate a guaranteed job program launched in 2020 in Austria. Our evaluation is based on three approaches, pairwise matched randomization, a pre-registered synthetic control at the municipality level, and a comparison to individuals in control municipalities. This allows us to estimate...

We analyse how the financial support for long-term elderly care affects the level of household savings. Using a difference-in-differences estimator, we investigate the 2002 Scottish reform, which introduced free formal personal care for all the elderly aged 65 and above residing in Scotland. Our...

In this paper, we investigate the response of female lone parents to two reforms to the welfare system in Australia. We look at changes to both hours and participation and focus on the channels of adjustment, in particular the role of job changes for adjustment in hours. We highlight the...

This paper exploits a quasi-natural experiment – the U.S. granting of Permanent Normal Trade Relations (PNTR) to China after China's accession to the World Trade Organization – to examine whether trade liberalization affects the incidence of child labor in China. PNTR permanently set U.S....

This paper suggests a causal framework for disentangling individual level treatment effects and interference effects, i.e., general equilibrium, spillover, or interaction effects related to treatment distribution. Thus, the framework allows for a relaxation of the Stable Unit Treatment Value...

We exploit the 1996 reform of the German child benefit program to identify the causal effect of heterogeneous child benefits on fertility. While generally the reform increased child benefits, the exact amount of the increase varied by household income and the number of children. We use these...

We estimate the effects of the arrival of 2.5 million Syrian migrants in Turkey by the end of 2015 on the labor market outcomes of natives, using a difference-in-differences IV methodology. We show that relaxing the common-trend assumption of this methodology - unlike recent papers in the same...
