sure, sanctions may very well be one of the factors causing such high inflation levels (although I am hesitant to say that they completely explain away the massive increase in the money supply. FWIW, according to IMF, in 2008 Iran's M1 base has been around $70 billion[1]. Giving a population of over 75M a $1.5 * 365 does nicely increase that base by around 50%). My main main point however was not to claim that the UBI program caused the inflation, rather to challenge the reliability of the main claim of the report as to the change the UBI makes to people's working behavior. Under such high inflation, whatever the cause, people need to work more, rather than less, to make ends meet, so comparing their behavior to pre-inflation periods is just bad science.
