We propose a novel structural estimation framework in which we train a surrogate of an economic model with deep neural networks. Our methodology alleviates the curse of …
Solving dynamic economic models that capture salient real-world heterogeneity and non- linearity requires the approximation of high-dimensional functions. As their dimensionality …

New generation airborne embedded system has deployed Graphical Processing Units (GPUs) to raise processing capability to meet growing computational demands. Comparing …
We propose a scalable method for computing global solutions of nonlinear, high- dimensional dynamic stochastic economic models. First, within a time iteration framework …
This paper introduces the concept of``self-justified equilibria" as a tractable alternative to rational expectations equilibria in stochastic general equilibrium models with heterogeneous …
