Trade Fragmentation, Currency Unions and the Role of Fiscal Transfers

Abstract. I develop a dynamic quantitative New Keynesian model of trade to study how cross-country fiscal transfers can stabilize a monetary union following an asymmetric trade shock. The key departure from a representative-agent benchmark is that country-level marginal propensities to consume are substantial, heterogeneous, and below one, so temporary transfers affect current consumption and desired labor supply. I apply the model to the 2025 U.S. tariff shock in the euro area. A simple zero-sum fiscal rule reduces total labor-market distortions by approximately 6%, but offsets almost 75% of the additional distortions generated by the absence of independent monetary policy. Transfers operate mainly as income insurance rather than through large changes in labor demand: they reduce cross-country variation in consumption growth but have little effect on variation in observed employment. This stabilization can come at the cost of welfare losses when the shock affects mainly richer countries, as in the 2025 U.S. tariff episode.

The welfare implications of the China Shock across US States and Skill Groups 

Abstract. I build a dynamic quantitative spatial trade model with firm and worker heterogeneity, mobility frictions, and short-run unemployment to quantify the regional and distributional effects of the China Shock across U.S. states. The baseline model implies an average welfare gain (0.1%) but substantial heterogeneity across skill groups. Average welfare gains are 0.01% for unskilled workers —who lose in 17 of 50 states—versus 0.31% for skilled workers, who lose in only 7 states. The model predicts an average increase of 0.78% in the skill premium, with more exposed states experiencing larger increases. Finally, I find long-run gains in every state for both types of workers.

Mind the app: do European deposits react to digitalisation? , with Nadya Wildmann , Beatrice Scheubel , Livio Stracca , Francesco Asvisio and Luisa Fascione . 

Abstract. The March 2023 banking turmoil has intensified discussions whether social media and the digitalisation of finance have become significant factors in driving severe deposit outflows. We introduce the concept of deposits-at-risk and utilize quantile regressions for disentangling determinants of stressed outflows at the lowest tail of the distribution. For a sample of large banks directly supervised by the ECB, our findings indicate that an increased use of online banking services leads to a small amplification of extreme deposit outflows, but this effect is not further exacerbated by the availability of a mobile banking app. Online banking use and availability of a mobile app do not have a causal effect on deposit volatility in normal times. Finally, social media are impactful only in idiosyncratic cases.

Technology Diffusion at the Top, Firm-to-Firm Technology Transfers and the Welfare Gains from Openness. Second Year Paper, Boston University, 2023.

Abstract. I develop a static model to study the macroeconomic effect of multinational production (MP) and trade in the context of technology diffusion among the best firms in the sector and simultaneous firm-to-firm technology transfers between sectors. I show the importance of separately calibrating aggregate spillovers and firm-to-firm technology transfers in the buyer-supplier linkages. I focus my analysis on non-tradable suppliers, and show how different levels of technology transfer affect the gains from openness.
