CompEcon

A Python version of Miranda and Fackler's CompEcon toolbox

The aim of this toolbox is to provide a Python toolbox to replicate the funcionality of Miranda and Fackler's CompEcon toolbox, which was written to accompany their Computational Economics and Finance and is coded in Matlab.

The source for this project is available in Github.

A major difference in this implementation is that much of the code is object-oriented, providing classes to represent:

• Interpolation bases: Chebyshev, Spline, and Linear
• Dynamic programming models: with discrete and/or continuous state and action variables
• Nonlinear problems
• Optimization problems

Some other differences are:

• The solution of dynamic models is returned as a pandas dataframe, as opposed to a collection of vectors and matrices.
• Some additional functionality is included, most notably for Smolyak interpolation.
• Basis objects are callable, so they can be used to interpolation function by "calling" the basis.

The toolbox also replicates some of the demos and examples from Miranda and Fackler's textbook. The examples can be found in the .\textbook directory, while the demos are in the directories .\demos (for .py files) and .\notebooks (for Jupyter notebooks).

At this time the documentation is incomplete, so the best way to get going with this toolbox is by exploring the notebooks.

compecon's Issues

Issue on page /notebooks/slv/05 Cournot equilibrium model.html

Hola Randall, hoy instale Compecon y estaba probando el código con el ejercicio que dejo en la clase de Cournot con el método de Broyden. Como el error que me genera habla del jacobiano, pensé que podría ser la nueva actualización.
Error:

Cualquier cosa mi código es este (si es un error mío disculpas):

Muchas gracias por su tiempo y saludos,

Errors installing/importing in python3.6

Hi Randall,

Thanks for putting this project together. I'm using python3.6 and attempting a plain install python setup.py install and getting the following error:

File "build/bdist.macosx-10.5-x86_64/egg/compecon/quadrature.py", line 9
    def __init__(self, dist, *args):
                                   ^
SyntaxError: unexpected EOF while parsing

Weird as it is, it doesn't break the install. When I try to from compecon import Basis I get this error:

In [2]: from compecon import Basis
  File "/Users/btengels/Dropbox/Econ/VCS_Tengelsen/Book code/CompEcon-python-master/compecon/demos/setup.py", line 106
    fname = name + f'--{n+1:02d}.pdf'
                                    ^
SyntaxError: invalid syntax

Is this familiar at all?

Error in Asset Replacement Model model.solve()

Dear Randall,

I'm getting an error when trying to run the Asset Replacement Model notebook in the Discrete Time Continuous State Dynamic Programming section, specifically in the model.solve() code.

please your support
thanks
