[Roberto Iacono @Roberto__Iacono]

Glad to be finally (in person!!) at @uioecon for the kick-off of the #TaxFair @forskningsradet-funded project led by @pgpiacquadio. Exciting years (and research) ahead!

[Johannes Fleck @_jofleck]

Many thanks @Jonheathcote - studying the progressivity of US state governments with you, @KStoresletten & @glviolante is a genuine privilege and pleasure!

[Jonathan Heathcote @Jonheathcote]

Johannes is a great student -- & co-author! His exciting JMP is about variation across US states in MPCs out of stimulus checks (a la @ProfJAParker & Souleles). He correlates this variation with cross-state variation in tax progressivity & connects the two in a structural model.

[Johannes Fleck @_jofleck]

@kari_charlotte Many thanks. Very humbled 😌

Congrats @pgpiacquadio! Very well-deserved

[Paolo Piacquadio @pgpiacquadio]

This is a great honor for me! Thanks to the EEA and the editors of JEEA.
Despite my head of department warmly suggests I focus on writing papers (for tenure sake), I find refereeing really important and rewarding. So I am really happy of this award!

"You can suspend many things. But not gravity, the speed of light and other facts."

[Johannes Fleck @_jofleck]

Do ethnic enclaves perpetuate cultural fault lines?

No - says @achard_pascal's JMP & indicates what does

Fascinating data (pill use of girls, no kidding!) + identification (random placement of asylum seekers)

Applied micro at its finest

What I learned from JMP of @kristoberg

Income taxes reflect preferences for vertical AND horizontal equity

Great job at explaining the magic needed to decompose their contributions (theory + empirics)

@voxeu @ecb @Adrian_Mo_ @stroebel_econ @StefanoGiglioEc @m_maggiori @ProfJAParker 4/4 Take away:

1) EU portfolio heterogeneity is also driven by cross-country differences in beliefs

2) How much do beliefs matter relative to other relevant factors? -> More research needed

3) Erosion of trust in social and communal institutions can show up in portfolios

[Johannes Fleck @_jofleck]

@voxeu @ecb @Adrian_Mo_ 3/4 Related exciting research

@stroebel_econ @StefanoGiglioEc @m_maggiori and Utkus study beliefs of wealthy retail investors – we focus on households

Meeuwis @ProfJAParker Schoar and Simester study beliefs in models of the world – we focus on social and communal insurance
