International Sanctions and Emigration

open access: yesSSRN Electronic Journal
In this first empirical analysis of how sanctions affect international migration, we apply two estimation strategies, a panel difference-in-differences model and an event study approach. Our dataset covers 79,791 dyad-year observations, reflecting migration flows from 157 origin countries to 32 (largely OECD) destination countries between 1961 and 2018.

The number of prior knee arthroscopies is associated with an incremental increase in risk of revision in a subsequent total knee arthroplasty

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The aim of this study was to estimate the relative risk of revision for total knee arthroplasty (TKA) with prior knee arthroplasties compared to TKAs in knees without prior surgery. In addition, this study aimed to assess if there was a dose‐response relationship between the number of prior knee arthroscopies and the risk of TKA ...
