We introduce a deep learning-based forecasting method that addresses spillover effects in shared markets using time series data and counterfactual controls. This method is demonstrated through an empirical analysis of promotional deals in US grocery stores.

Our study reveals that for "spectacle"-oriented films, piracy can complement box-office sales by enhancing the viewing experience, while for "story"-oriented films, it tends to displace sales, highlighting how the value of creative content and its distribution context affect copyright infringement impacts.

The study assembles new data to construct a census of worldwide web server use across the globe. We find that open-source software adaption is not primarily driven by income factors, rather than by the skill of the workforce.
