Causal Knowledge Guided Societal Event Forecasting [PDF]
Data-driven societal event forecasting methods exploit relevant historical information to predict future events. These methods rely on historical labeled data and cannot accurately predict events when data are limited or of poor quality. Studying causal effects between events goes beyond correlation analysis and can contribute to a more robust ...

Identification and Inference Using Event Studies [PDF]
We discuss the use of event studies in macroeconomics and finance, arguing that many important macro‐finance questions can only be answered using event studies with high‐frequency financial market data. We provide a broad picture of the use of event studies, along with their limitations.

Event-by-event hydrodynamics and elliptic flow from fluctuating initial state
We develop a framework for event-by-event ideal hydrodynamics to study the differential elliptic flow which is measured at different centralities in Au+Au collisions at Relativistic Heavy Ion Collider (RHIC).

Pre-event Trends in the Panel Event-study Design
We consider a linear panel event-study design in which unobserved confounds may be related both to the outcome and to the policy variable of interest. We provide sufficient conditions to identify the causal effect of the policy by exploiting covariates related to the policy only through the confounds.
