ConsPortfolioFrameModel

This file contains classes and functions for representing, solving, and simulating agents who must allocate their resources among consumption, saving in a risk-free asset (with a low return), and saving in a risky asset (with higher average return).

This file also demonstrates a “frame” model architecture.

class HARK.ConsumptionSaving.ConsPortfolioFrameModel.PortfolioConsumerFrameType(**kwds)

Bases: FrameAgentType, PortfolioConsumerType

A consumer type with a portfolio choice, using Frame architecture.

A subclass of PortfolioConsumerType for now. This is mainly to keep the _solver_ logic intact.

birth_aNrmNow(N)

Birth value for aNrmNow

birth_pLvlNow(N)

Birth value for pLvlNow

solve()

Solve the model for this instance of an agent type by backward induction. Loops through the sequence of one period problems, passing the solution from period t+1 to the problem for period t.

Parameters:

verbose (boolean) – If True, solution progress is printed to screen.

Return type:

none
