Our latest paper "Innovation on Wings ✈️" is out on Management Science (and open access!), joint with @prithwic, Do Yoon Kim & @shwesley!

We find that when inventors are in locations connected by nonstop flights they are more likely to cite & collaborate w/ each other.

🧵1/4 We exploit a discontinuity in flights at 6000 miles due to regulations building on prior work by @FilipeCampante & Yanagizawa-Drott. These discontinuity allows us to exploit how non-stop flights "shorten" distances when it comes to innovation

Nuestro paper, con @anamibanez & @svrozo, estudiando el impacto de la regularización masiva de Venezolanos en Colombia en el 2018 en los mercados laborales ha sido aceptado por la revista Journal of Development Economics!

Aquí un pequeño resumen. En el 2018 el Presidente @JuanManSantos decretó la regularización de estatus migratorio de ~500K venezolanos viviendo en Colombia. El Presidente @IvanDuque implementó la decisión (una bella muestra de que para los Colombianos tenderle la mano a los Venezolanos cruza partidos).

🚨PAPER ACCEPTED🚨
Our paper w/@anamibanez & @svrozo documenting the effects of providing regular migratory status to 300K Venezuelans in Colombia in 2018 has been accepted by the Journal of Development Econ, just as Colombia ruled it’ll extend the amnesty to 1.8 million Vzlns 🧵 In 2018 outgoing President @JuanManSantos decreed that ~500K undocumented Venezuelan refugees in Colombia will receive a special visa (PEP) which with they can work & access services. President @IvanDuque implemented the decision.

Really recommend you watching this super insightful lecture by @pol_antras on the current state and (post-COVID) future of globalization at the ECB with some super interesting stylized facts. This is a thread with my takeaways... 1/8

Full video here: First, we're seeing a "slowbalization" rather than deglobalization. Despite a slowdown in recent years most measures of globalization (take trade as % of GDP) continue to be quite high historically. Note too that these measures are upper bounded so they can't go up forever 2/8

THREAD: In light of @AKurmanaev's fabulous @nytimes piece on the collapse of #Venezuela (nytimes.com/2019/05/17/wor…) the discussion on "who is to blame" for this might not be urgent, but some have took the task of blame that on someone other than the Venezuelan regime 1/14 For example, last month Jeffrey Sachs & Mark Weisbrot claimed 2017 US sanctions imposed on Venezuela caused 40K+ deaths. Their analysis is based on one graph comparing oil production of Venezuela & Colombia, where any difference post-2017 is BECAUSE of sanctions 2/14

@BootsRiley Boots, this will be my last answer in an attempt to have a serious, genuine, conversation about the facts. If not for you, at least for the many that are reading. Here's a thread. @BootsRiley 1/ I'm aware that there is a vast history of US interventions in LatAm and other regions, that have ended very badly. And I understand that the American people are weary of falling into those mistakes again. I really do.

According to reports it is expected that today @POTUS Trump will recognize @jguaido as interim President of #Venezuela after he is sworn in following the Venezuelan constitution. I explain why. 1/x Article 233 of the Venezuelan constitution specified that in the absence of a president elect, the president of the National Assembly becomes the interim president and should call to elections within 30 days 2.x
