Hello !

I am an economic theorist, with a focus on information economics and dynamic games.

I am currently a 6th year PhD Candidate in Economics at Columbia University.

From September 2025, I will be a Postdoctoral Prize Research Fellow at Nuffield College, Oxford.

• The Dynamics of Instability
  Short abstract

  Even if pure instability does not generate any short term expected gains, players with opposed interests can leverage it to obtain long term changes. In equilibrium, the least favored player uses instability in a decreasing manner as we get closer to a stable state; long run outcome exhibit path dependency and can sustain high inequity.

• A Mean-Field Game Model for the Evolution of Cities
  Short abstract

  We propose a MFG model for the evolution of residents and firms densities, coupled both by labour market equilibrium conditions and competition for land use; the former induces a new optimal transport coupling in the system of two HJB and two Fokker-Planck equations. This MFG has a convex potential which enables us to find weak solutions by a variational approach. In the case of quadratic Hamiltonians, we reformulate the problem in Lagrangian terms and develop a numerical solution method.

Work in progress

• When and what to learn in a changing world
  Abstract

  I study a model of infrequent information acquisition about a changing state, in which a decision-maker facing repeated choices controls both the timing and content of periodic updates about current circumstances. I derive a general characterization of solutions. This pins down long run dynamics of beliefs, which reduce to a simple cyclical pattern despite the richness of the policy space. I use the model to study the effect of the environment (costs, underlying volatility) on the optimal information acquisition dynamics, as well as an application to a stylized investment problem.

  Draft coming soon.

• Cultural transmission and historical origins of attention to environmental issues
  Abstract

  The realized intensity of deviations from typical climatic conditions in ancestral generations influences how much descendants care about the environment. The effect exhibits a U-shape where more stable and more unstable climates lead to higher attention, with a dip for intermediate realizations. We propose a theoretical framework where the value of costly attention to environmental conditions depends on the perceived stability of the environment; prior beliefs about which are shaped through cultural transmission by the experience of ethnic ancestors. The U-shape results from a dual purpose of learning about the environment: optimal utilization of typical conditions and protection against extreme events.

• Dynamic information acquisition with memory loss
  Abstract

  Does memory loss lead to more or less information acquisition? When information may be forgotten before it can be used to make decisions, the marginal value of an individual signal is subject to two opposite forces: it decreases since it is less likely to improve decisions and improves since having more information may improve overall retention. This leads to asymmetric distortions in sequential optimal information acquisition: memory loss leads to lower standards for information that confirms the status quo but over-confirmation for information that contradicts it.
