This paper examines the evolution of public policies before the scheduled political elections based on the government responses to the Covid pandemic. The results of an event study in a sample of countries that experienced political elections during the first year of the pandemic suggest that...

The persuasion rate is a key parameter for measuring the causal effect of a directional message on influencing the recipient's behavior. Its identification has relied on exogenous treatment or the availability of credible instruments, but the requirements are not always satisfied in...

We discuss important features and pitfalls of panel-data event study designs. We derive the following main results: First, event study designs and distributed-lag models are numerically identical leading to the same parameter estimates after correct reparametrization. Second, binning of effect...

Linear panel models, and the "event-study plots" that often accompany them, are popular tools for learning about policy effects. We discuss the construction of event-study plots and suggest ways to make them more informative. We examine the economic content of different possible identifying...

We discuss important properties and pitfalls of panel-data event study designs. We derive three main results. First, binning of effect window endpoints is a practical necessity and key for identification of dynamic treatment effects. Second, event study designs with binned endpoints and...

We provide evidence of the impact of the COVID-19 pandemic on racial hate crime in England and Wales. Using various data sources, including unique data collected through Freedom of Information (FOI) requests from UK police forces, a difference-in-difference and event study approaches, we find...

Linear panel models and the "event-study plots" that often accompany them are popular tools for learning about policy effects. In this paper, we introduce the "xtevent" package for Stata, which enables the construction of event-study plots following the suggestions in Freyaldenhoven et al....

We discuss properties and pitfalls of panel-data event study designs. We derive three main results. First, assuming constant treatment effects before and/or after some event time, also known as binning, is a natural restriction imposed on theoretically infinite effect windows. Binning identifies...

We document that a huge frustration shock, clearly unrelated to government's actions, was perceived to lead to substantial punishment at the polls months later. In particular, we provide evidence that Brazil's 7-1 humiliating defeat to Germany in the 2014 World Cup was perceived by financial...
