#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Description:
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Created by Mani Rouhi Rad on 11/13/2017
#
# This version includes early diff in diff results of PIEA land use changes
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# To Do's:
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# 1) Parallel trends assumption: Different combinations of treatment and control to check the parallel trends assumption.
# 2) Add land use for each year as control. Provide summary statistics for land use change. Blair is taking care of that.\
# 3) Check how these land use changes compare to a broader range of incentive based land use change programs
# 4) how much increase do we expect? we have hectares that have changed for each region
# 5) try the regressions with net forest loss
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Questions:
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Important mentions:
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# data_reg = data_reg[year > 2004] line 276-ish. If we get better rainfall data, we can use data prior to 2005 as well.
