Create person-reform dataset

[MaxGhenis]

How about this schema, with one row per person per reform, i.e. 3x # person records:

• Person-level demographics:
  • Disability status
  • Region
  • Age group
  • Weight (household weight)
• Baseline household-level:
  • Net income
  • Net income decile
  • Capital income
  • Family archetype
  • Housing benefit receipt (needs to be aggregated to household from BU)
• Household-level reform effects:
  • Net income
  • Change in net income
  • % change in net income
  • UBI amount
  • Change in tax liability
  • Change in benefits
