We had two great in-house (virtual) seminars - fun and useful - thanks to all and especially to @MilenaAlmagro, @clementi_gl, @pedrohcgs and others not on twitter 14/
Bonus tweet: a movie that shows how the model scales: the city on the right has 4*the area, 4*the population, 4* the initial cluster in symmetric locations. The dynamic as a fraction of the population is identical. 15/end

Quanto rendono i fondi pensione in Italia? Un informativo articolo de @ilpost usa dati @covip per confrontare i rendimenti dei fondi pensione, la loro distribuzione e i loro costi 1/
ilpost.it/?blog_post=qua…
L'articolo dipinge un quadro sconfortante. Il rendimento, anche dei fondi negoziali (quelli istituiti in base ad accordi sindacali), è ben lontano dai benchmark. La varianza è enorme 2/
I costi di tali fondi, anche quelli negoziali, sono alti. 3/

A paper with @albertobisin: Learning Epidemiology by Doing: The Empirical Implications of a Spatial SIR Model with Behavioral Responses.
papers.ssrn.com/sol3/papers.cf… 1/
How does geography affect the diffusion of COVID-19? How can we compare the U.S. to Ireland? New York to Miami? How do we make sense of figures like this? 2/
In this paper, we simulate a Spatial SIR model with behavioral responses showing how geography places restrictions over the empirical predictions of the epidemic models 3/

THE ECONOMICS OF INSTITUTIONAL DISCRIMINATION: A PRIMER
Much has been written recently about the failure of economics to study institutional discrimination. But, I believe there are important contributions to improve upon. Here is a survey (with a bias for my own work -sorry) 1/
In the last JEP, sociologists Small and Pager (pubs.aeaweb.org/doi/pdfplus/10…)
claim that economists do not study implicit biases and institutional discrimination. @WSpriggs in an open letter adds that economists should study race as a social construct bit.ly/37x0k1x 2/
Economists have tools to study these issues and have done so. The critics focus on the old (but textbook-popular) notion of statistical discrimination modeling (exogenous) stereotypes (=group averages), which they dislike because it places the burden of change on the victims 3/

Un articolo sul @fattoquotidiano (con molti altri, come @Avvenire_Nei) titola minaccioso "Coronavirus, negli Usa i disabili non hanno diritto alle cure contro il Covid". Trattasi di bufala. L'articolo distorce non poco i fatti, che vado a descrivere indicando le fonti. 1/9
Di vero nell'articolo c'è che alcune associazioni di categoria hanno intrapreso iniziative (meritevoli!) per prevenire la possibilità che la disabilità venga usata come criterio, ma queste iniziative non affermano che questo sia un criterio in uso 2/ dredf.org/covid-19-advoc…
Questo e gli altri articoli sull'argomento riprendono (senza citarlo) un articolo di qualche giorno fa apparso sul New York Times, anch'esso impreciso (ma non così fuorviante). Ma era un editoriale, non un articolo 3/ nyti.ms/3bgjlpN

I am not a taxation expert but I would like to suggest an interpretation of the @gabriel_zucman - @wwwojtekk
diatribe (a good summary of links here by @Undercoverhist: ). Hope this helps the few readers patient enough to follow /1
TL;DR: The question "Who pays how much taxes?" is
ill-posed. Better question: "who pays how much taxes RELATIVE TO WHAT SCENARIO?" There is an even better question but I'll write it later /2
Zucman/Kopczuk are ultimately debating over which counterfactual makes more sense. But counterfactuals are a bitch... I thought a lot about counterfactuals in my research. They require clarifying what is changing and what is fixed. That is almost never obvious without a model /3
