Version 2 of VFI Toolkit vfitoolkit.com/updates-blog/2…

OLG Transition Paths: Example based on Conesa & Krueger (1999) vfitoolkit.com/updates-blog/2…

getIMFData() adds GFS databases. Requires minor update to inputs for CPIS and DOT databases. See github for example using GFS.

24min video about 'Introduction to Life-Cycle Models' vimeo.com/750251629 (talks about the Intro to Life-Cycle Models which uses 25+ examples in VFI Toolkit to show how to build and solve a life-cycle model, as well as covers important concepts and modelling techniques)

An Introduction to OLG Models vfitoolkit.com/updates-blog/2…

1000 Downloads!!! The wrong way :P vfitoolkit.com/updates-blog/2…

Portfolio-Choice with Epstein-Zin preferences vfitoolkit.com/updates-blog/2… Portfolio-choice models have households choosing both savings, and the division of savings between safe and risky assets. Version 2.1 of VFI Toolkit introduces Case3 to solve these.

Behavioural Life-Cycle Models Impatience, Temptation and Self-Control, Loss Aversion and Ambiguity Aversion can now all be handled in life-cycle models! (and OLG ;) vfitoolkit.com/updates-blog/2…

v2.2: Same same, but faster! 🔥 VFI Toolkit is now much faster thanks to implementing Tan improvement for all agent distribution computations (it is so fast the FnsToEvaluate got embarassing, so these were overhauled for speed too) Huge shout to Eugene Tan for this genius idea!

GMM Estimation of Life-Cycle models shorturl.at/lvnU9 Life-Cycle models 45-50 in the Intro to Life-Cycle models show how to do GMM estimation in VFI Toolkit with just 5-10 lines of code (after model and data work). I'm excited about this! :D

Human Capital! Life-Cycle Model 42: Female Labor Force Participation History Life-Cycle Model 43: Uncertain Human Capital shorturl.at/VgAwc (two new life-cycle models in the Intro to Life-Cycle Models, both have assets + human capital)

(New) Example: Huggett, Ventura & Yaron (2006) discourse.vfitoolkit.com/t/example-hugg… Does two things: i) use PSID data in Matlab to estimate life-cycle profiles ii) calibrate life-cycle model with human capital to reproduce the life-cycle profiles

VFI Toolkit contains discretization methods for: AR(1), AR(1) w/ gaussian-mixture, AR(1) with stochastic volatility, AR(2), VAR(1), life-cycle AR(1), life-cycle AR(1) w/ gaussian-mixture. Codes harmonize inputs, outputs, notation. Examples: shorturl.at/A6yX2

(New) Life-Cycle Model 27 Discretize earnings dynamics 'Model 5' of Guvenen, Karahan, Ozkan & Song (2021), use in exo-labour life-cycle model. All discretization methods are extensions of Tanaka-Toda method. Lots of gaussian-mixtures :D surl.li/pjeetp

Online Video Workshop on VFI Toolkit vfitoolkit.com/2025-workshop-… Original was taught in-person at LSE in May 2025. Videos cover toolkit concepts and walk through codes. All slides & codes available to play with. Great intro to VFI Toolkit.
