What an incredible journey the PhD has been! Yesterday I graduated from @tcddublin.bsky.social and I'm officially Dr. Arrigoni! 🎓☘️
And as this chapter ends, a new one is about to begin. I’m thrilled to share that in September I will join the @banquedefrance-off.bsky.social as a Research Economist!

Fantastic to see @economist.com covering our data and paper, published in The Journal of Economic Inequality (with @taramcindoecalder.bsky.social Laura Boyd)! 🚀

The piece examines inheritance's renewed role in wealth, inequality, and marriage choices, among rich countries.

Exciting news! I successfully defended my PhD thesis yesterday at @tcdeconomics.bsky.social ☘️🎉
A huge thanks to the viva commission - Mark Spiegel, Paul Scanlon, @fontananicola.bsky.social - for the invaluable feedback + my supervisors A. Bénétrix & @davideromelli.bsky.social , for their guidance!

Model's bottom line: inequality shapes foreign monetary policy spillovers to GDP mainly via the financial channel.
Do the data support this? Yes.
I study the interaction between inequality and financial openness. Financially closed (open): higher inequality = weaker (stronger) spillovers.

Bond mkt access within-country: constrained ×, unconstrained ✓.
But unconstrained HHs differ btwn countries (home bias, fees,...).
I raise foreign bond holding cost for country 3, now representing an EME. This replicates the empirical result for EMEs: higher inequality = weaker spillovers.

In the baseline scenario (classic spillover), US monetary tightening causes a GDP contraction in foreign countries, a stronger dollar, and reduced exports.
As in the empirics, higher inequality (higher proportion of constrained households) amplifies negative spillovers in foreign countries.

Why? 🔍Theoretical framework
Scope: understand what drives the discrepancy of the effects between AEs and EMEs.
Open-economy model of Eichenbaum et al. (2021)
+ household heterogeneity: financially constrained vs unconstrained HHs. Gini generated by income differences between the two HHs.

🗝️ Results
Inequality does influence how foreign GDP responds to a US tightening. GDP contracts 2/3 times more when inequality is higher than average.
But... Greater inequality amplifies the negative spillover effects to GDP in AEs, while it mitigates them in EMEs.

📢I'm on the #EconJobMarket!
My #EconJMP studies how inequality in foreign economies shapes the effects of Fed's tightening on their GDP.
Spoiler: higher ineq = larger (smaller) GDP drop in AEs (EMEs). Mainly via financial channel.
