Heterogenous Agents Resources & toolKit
Often a control variable has a limited domain. For example, `c
A desideratum for future versions of HARK is a syntax for mathematical expressions in model definitions. This syntax need not be the native Python syntax, though this is what is...
Continuing from [here](https://github.com/econ-ark/HARK/issues/620#issuecomment-813603497) > But, per our earlier discussion that the "problem" may change, say, at different ages of life, if we can have an architecture can handle that for...
No default MrkvArray parameter for πΌππππππ²πππππππππ’ππ, which cause an error on initialization with πΌππππππ²πππππππππ’ππ() ``` ~/projects/econ-ark/HARK/HARK/ConsumptionSaving/ConsMarkovModel.py in updateSolutionTerminal(self) 763 764 # Make replicated terminal period solution: consume all resources, no...
As is, our only method for automatically generating discretized joint distributions is `combineIndepDstns`. HARK.utilities should also contain methods for making discrete approximations to correlated multivariate distributions. Three requests: 1) To...
These are features that are of interest to HARK that are not yet supported in Dolo, that are high priority according to @llorracc > 1. "Cycles" in which the agents...
@llorracc has recommended looking into [bellman](https://bellman.dev/docs/latest/index.html), a toolkit for model-based reinforcement learning (MBRL), as inspiration for HARK. What is `bellman`? It's an implementation of a kind of reinforcement learning algorithm...
The point of the FramedAgentType is to make an AgentType class that has all of the model-specific logic modularized out into configurable Python functions and objects. (Eventually, these will be...
Originally discussed here: https://github.com/econ-ark/HARK/pull/1071#issuecomment-972894786 In the FramedAgent example, I've tried to use the `read_shocks` functionality to use the exact same shocks in the PortfolioConsumerType and the PortfolioConsumerFrameType, on the theory...
A true model is an infinite, continuous model with a single solution. There are many ways to approximate such a model with finite agents and discretization of continuous spaces. The...
