Economics Online Seminars As education moves to the internet, so are research seminars. Some of these seminars are regular and others appear to be temporary due to the covid-19 and the lockdown. 

Here are some examples from the American Economic Association


Regular seminar(s)


The Chamberlain Seminar - A regular open online international
inter-institutional econometrics seminar in honor of Gary Chamberlain
(1948–2020)

Temporary Seminars


Virtual Macro Seminar Series 
Online Seminar in Gender Economics
Virtual IO seminar
...



And also,


Princeton Webinar Series on COVID Economics


Beyond the AEA list and the Princeton webseminar, I am looking for links to find conferences, workshops, and talks hosted by economic research institutions from all over the world. One requirement is that registration be open to all, as some of the online seminars are reserved for faculty only.



Update

Virtual Economics stores various online seminars with a super useful calendar.
I have two here to add to your list.  

Brookings Insitute

https://www.brookings.edu/events/

St. Louis Fed  Economic lowdown
(FREE)

https://www.econlowdown.org/

There is also the National Association of Business Economics (NABE)
But to get access to their webinar resources you have to register on their site.
I know this won't qualify as it is not free but they are a good source of up-to-date information.  I felt that this would be a good share.
