Efficient Likelihood-based Estimation via Annealing for Dynamic Structural Macrofinance Models
Andras Fulop, Jeremy Heng, Junye Li
Most solved dynamic structural macrofinance models are non-linear and/or non-Gaussian state-space models with high-dimensional and complex structures. We propose an annealed contro…
