ConsumerDemands 0.5.0

================
ConsumerDemands
================

A Python package for computing general consumer demand systems from
preference primitives.

Given preference parameters (alpha, beta, phi) for a Constant Frisch
Elasticity (CFE) demand system, this package computes:

- Frischian demands (given marginal utility of income and prices)
- Marshallian demands (given budget and prices)
- Hicksian demands (given utility level and prices)
- Budget shares, income elasticities, and Engel curves

Installation
============

With pip::

    pip install ConsumerDemands

For plotting support (Engel curves)::

    pip install ConsumerDemands[plot]

From source::

    git clone git@bitbucket.org:ligonresearch/demands.git
    cd demands
    pip install -e .

Quick start
===========

::

    from consumerdemands import marshallian

    y = 10.0                          # budget
    p = [1.0, 2.0]                    # prices
    parms = {'alpha': [1., 1.],       # preference weights
             'beta':  [1., 1.],       # Frisch elasticities
             'phi':   [0., 0.]}       # subsistence parameters

    x = marshallian.demands(y, p, parms)
    w = marshallian.budgetshares(y, p, parms)
