Estimate redistributed fishing effort and welfare loss/gain from changes in policy or change in other factors that influence fisher location choice.
Usage
run_policy(
project,
mod.name = NULL,
policy.name = NULL,
betadraws = 1000,
marg_util_income = NULL,
income_cost = NULL,
zone.dat = NULL,
group_var = NULL,
enteredPrice = NULL,
expected.catch = NULL,
use.scalers = FALSE,
scaler.func = NULL
)
Arguments
- project
Name of project
- mod.name
Model name. Argument can be the name of the model or the name can be pulled the `modelChosen` table. Leave
mod.name
empty to use the name of the saved `best` model. If more than one model is saved,mod.name
should be the numeric indicator of which model to use. Usetable_view("modelChosen", project)
to view a table of saved models.- policy.name
List of policy scenario names created in zone_closure function
- betadraws
Integer indicating the number of times to run the welfare simulation. Default value is
betadraws = 1000
- marg_util_income
For conditional and zonal logit models. Name of the coefficient to use as marginal utility of income.
- income_cost
For conditional and zonal logit models. Logical indicating whether the coefficient for the marginal utility of income relates to cost (
TRUE
) or revenue (FALSE
).- zone.dat
Variable in primary data table that contains unique zone ID.
- group_var
Categorical variable from primary data table to group welfare outputs.
- enteredPrice
Price data. Leave as NULL if using price data from primary dataset.
- expected.catch
Required for conditional logit (
logit_c
) model. Name of expected catch table to use. Can be the expected catch from the short-term scenario (short
), the medium-term scenario (med
), the long-term scenario (long
), or the user-defined temporal parameters (user
).- use.scalers
Input for
create_model_input()
. Logical, should data be normalized? Defaults toFALSE
. Rescaling factors are the mean of the numeric vector unless specified withscaler.func
.- scaler.func
Input for
create_model_input()
. Function to calculate rescaling factors.
Details
run_policy
is a wrapper function for model_prediction
and welfare_predict
.
model_prediction
estimates redistributed fishing effort after policy changes, and welfare_predict
simulates welfare loss/gain.
