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 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...

This paper develops a simple approach to overcome the shortcomings of using a standard, single treatment-effect event study to assess the ability of an empirical model to measure heterogeneous treatment effects. Equally as important, we discuss how the standard errors reported in a typical...

Adopting a panel event study framework, we estimate the effect of unemployment on health outcomes by exploiting the variation in the timing of entering unemployment using longitudinal data for Greece. We find, that in the periods ahead of an unemployment event, health outcomes decline and unmet...

We assess the impact of announcements corresponding to different fiscal and monetary policy measures on the 10-year sovereign bond yield spreads (relative to Germany) of the 10 EMU countries during the period 01:1999 - 07:2016. Implementing pooled and country-fixed effects OLS regressions, we...

In this paper, information processing in spot and forward freight markets with respect to the Organization of the Petroleum Exporting Countries (OPEC) output announcements is investigated. We use the event study methodology to study returns in tanker freight spot and forward markets around OPEC...
