Fokker-Planck equations and n-dimensional Poincaré inequalities for isotropic densities

We consider new connections between the problem of trend to equilibrium for the n-dimensional Fokker-Planck equation of statistical physics, and weighted Poincaré inequality. To this aim we consider a class of n-dimensional Fokker-Planck equations with variable isotropic coefficient of diffusion and drift, inspired by the analogous one-dimensional Fokker-Planck equation appearing when studying the evolution of wealth distribution.

Welfare Effects of Electric Aircraft Introduction in the Italian Air Transport Market: A Structural Approach

We measured the social welfare effects of the introduction of all-electric aircraft using data from the air transport sector in Italy. The estimation of the welfare effects was done through a structural model typical of empirical industrial organisation work, in which equilibrium is estimated through the interaction of demand (from passengers) and supply (from airlines), and its perturbation due to the introduction, in some routes where it is technologically possible, of electrically powered ...

Flight Delays, Operational Responses, and Their Environmental Cost: Evidence from European Skies

This paper investigates the operational and environmental consequences of flight delays in the European airline industry. Using detailed 2023 data on aircraft rotations, we develop three complementary empirical models. The first quantifies within-flight mitigation, capturing how airlines strategically absorb departure delays through en-route and destination-side adjustments. The second examines delay propagation across consecutive flights, shedding light on the effectiveness of turnaround buf...

Leaving Home for University or Commuting? The Impact of Relocation Scholarships on Academic Progression

This study examines the causal impact of additional financial aid granted to students living far from university on their academic performance. It exploits an Italian policy that supports the relocation of scholarship recipients to the university city. Using a fuzzy regression discontinuity design based on a travel-time eligibility threshold, we compare the academic outcomes of scholarship holders enrolled at a medium-sized public university. Results indicate that relocated students accumulat...

Firm-level Drivers of Export Performance and External Competitiveness in Italy

This paper provides an in-depth study on the main firm-level drivers of external competitiveness during the recent crisis in Italy. We contribute to the debate on the Italian international position by presenting evidence based on a unique sample survey database (the MET dataset). Overall, our results confirm the high degree of heterogeneity of the Italian corporate sector and the well-known differences between internationalised and domestic companies in terms of performance as well as structu...
