The configuration file is the main control file for DaySim. The configuration file informs DaySim about inputs/outputs and various model settings.  These settings include input/output file names, types and locations, sample rates, DaySim pathbuilding weights, and also allow users to specify which DaySim model components should be executed.  A detailed description of the setting used in the NERPM-AB model is provided in section 4.3.

<h2>Seed Shadow Price</h2>

Shadow prices are constants that are added to individual microzones during the simulation of work and school location choice models. This is done to result in a good match between the following:

*Work locations of workers and employment
*School locations of students and enrollment

In DaySim, the long-term models (work and school location choice) are run ten times while updating shadow prices for all microzones during every iteration to create a seed shadow price file to be used as input to the full model run. The intent is to make sure that there is a good match between the number of job available in a microzones and the number of workers choosing the microzones as their usual work location. The same applies for students and school locations.

When the user updates the employment and/or school enrollment data, the Shadow Price step should be rerun.
