A Theory of Dynamic Product Awareness and Targeted Advertising

Rapid technological advances in advertising have enabled firms to better target those consumers most likely to buy their products. We develop a novel framework of demand as a network, where heterogenous consumers dynamically become ``aware'' of differentiated products, expanding their choice sets and improving on their possible matches thanks to advertising.

Commitment and Investment Distortions Under Limited Liability

We investigate how a combination of limited liability and preexisting debt distort firms’ investment and equity payout decisions.

Differentiable State-Space Models and Hamiltonian Monte Carlo Estimation

We propose a methodology to take dynamic stochastic general equilibrium (DSGE) models to the data based on the combination of differentiable state-space models and the Hamiltonian Monte Carlo (HMC) sampler.
