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…
(In)stability in the Dynamics of the Cross-Country Distribution of Income Per Capita
Davide Fiaschi, Paul Johnson
Using a panel of 102 countries from PWT 10.0 covering 1970-2019, we examine the veracity of the assumption that a time-homogeneous, first-order process describes the evolution of t…
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…
The spatial evolution of economic activities and the emergence of cities
Davide Fiaschi, Cristiano Ricci
This paper examines the spatial agglomeration of workers and income in a continuous space-time framework. Local markets feature spatial spillovers and both exogenous and endogenous…
