Supply Shocks in the Fog: The Role of Endogenous Uncertainty

Staff working paper 2026-12 Anastasiia Antonova, Mykhailo Matvieiev, Celine Poilly
Recessions feature elevated uncertainty. We develop a nonlinear imperfect-information New Keynesian model where procyclical information quality generates endogenous countercyclical uncertainty and precautionary saving. This demand channel can overturn the inflationary impact of negative supply shocks, making them deflationary, unless monetary policy stabilizes the output gap.

Let’s Get Physical: Impacts of Climate Change Physical Risks on Provincial Employment

Staff working paper 2024-32 Thibaut Duprey, Soojin Jo, Geneviève Vallée
We analyze 40 years’ worth of natural disasters using a local projection framework to assess their impact on provincial labour markets in Canada. We find that disasters decrease hours worked within a week and lower wage growth in the medium run. Our study highlights that disasters affect vulnerable workers through the income channel.

Classical Decomposition of Markowitz Portfolio Selection

Staff working paper 2020-21 Christopher Demone, Olivia Di Matteo, Barbara Collignon
In this study, we enhance Markowitz portfolio selection with graph theory for the analysis of two portfolios composed of either EU or US assets. Using a threshold-based decomposition of their respective covariance matrices, we perturb the level of risk in each portfolio and build the corresponding sets of graphs.

Adverse Selection with Heterogeneously Informed Agents

Staff working paper 2018-7 Mohammad Davoodalhosseini
A model of over-the-counter markets is proposed. Some asset buyers are informed in that they can identify high quality assets. Heterogeneous sellers with private information choose what type of buyers they want to trade with.

On the Evolution of the United Kingdom Price Distributions

We propose a functional principal components method that accounts for stratified random sample weighting and time dependence in the observations to understand the evolution of distributions of monthly micro-level consumer prices for the United Kingdom (UK).

Technology Adoption in Input-Output Networks

Staff working paper 2019-51 Xintong Han, Lei Xu
We study how input-output networks affect the speed of technology adoption. In particular, we model the decision to adopt the programming language Python 3 by software packages. Python 3 provides advanced features but is not backward compatible with Python 2, which implies it comes with adoption costs.
