Aiyagari: solve the standard Aiyagari model in 0.04 – 0.14 seconds with EGM + Young method (2010). Useful note (by Josep Pijoan-Mas) is available: Very short notes on the endogenous grid method. Code using iteration on marginal utilities or value functions: Aiyagari Code quick replication.
Entrepreneurial model: solve efficiently the Cagetti & DeNardi (2006, JPE) with endogenous borrowing constraint in 3s with DC-EGM, code available upon-request.
Housing model: solve standard housing macroeconomic models of Sommer & Sullivan (2018, AER) with EGM and DC-EGM. Useful note: Numerical Note: Solving Housing Macroeconomic Models with Discrete Choices, code available: Replication Code Sommer & Sullivan AER (2018).
