Aggregation Bias in Proxy Measurement: Nighttime Lights and Local Economic Activity

Davide Fiaschi, Angela Parenti, Cristiano Ricci

This paper studies when high-resolution signals aggregated to administrative units can recover unobserved local economic activity. We develop a reverse-regression framework for sig…

The invisible hand as an emergent property: a gradient flow approach

Giorgio Fabbri, Davide Fiaschi, Cristiano Ricci

We develop a general equilibrium model in which, at each instant, a short-run competitive equilibrium arises. Heterogeneity in factor allocation generates differential profit rates…

An integral transformation approach to differential games: a climate model application

Raouf Boucekkine, Giorgio Fabbri, Salvatore Federico +3

We develop an Integral Transformation Method (ITM) for the study of suitable optimal control and differential game models. This allows for a solution to such dynamic problems to be…

The spatial evolution of economic activities: from theory to estimation

Davide Fiaschi, Angela Parenti, Cristiano Ricci

This paper studies the evolution of economic activities using a continuous time-space aggregation-diffusion model, which encompasses competing effects of agglomeration and congesti…

Unveiling spatial patterns of population in Italian municipalities

Davide Fiaschi, Angela Parenti, Cristiano Ricci

We study the evolution of population density across Italian municipalities on the based of their trajectories in the Moran space. We find evidence of spatial dynamical patterns of…

A non-invariance result for the spatial AK model

Cristiano Ricci

This paper deals with the positivity condition of an infinite-dimensional evolutionary equation, associated with a control problem for the optimal consumption over space. We consid…
