RISE at a glance
=====================

RISE is the acronym for **R**\ationality **I**\n **S**\witching **E**\nvironments.

It is an object-oriented Matlab toolbox primarily designed for solving and estimating nonlinear
dynamic stochastic general equilibrium (**DSGE**) or more generally
Rational Expectations (**RE**) models with **regime switches** .

The switching process can be endogenous. RISE uses perturbation to approximate the nonlinear Regime Switching DSGE
(RS-DSGE) model and solves it using efficient algorithms.

In the paper "Efficient Perturbation Methods for Solving Regime-Switching DSGE Models", :cite:`Maih2015`
describes the basic problem and the solution approach in RISE. Other good references in the field include
various papers by `Tao Zha and Dan Waggoner <https://www.tzha.net/>`_, by Eric Leeper, among others.

RISE also implements special cases of the general RS-DSGE model, including

- The DSGE model with constant parameters
- The DSGE-VAR model
- **VAR**\s with and without switching parameters 
- **Panel VAR**\s with and without switching parameters 
- **Proxy VAR**\s with and without switching parameters 
- **SVAR**\s with and without switching parameters
- etc.

Within the DSGE framework, RISE also includes the solution and estimation of

- Loose commitment (or optimal policy) models
- hybrid expectations models
- models in which agents have information about future events
