Economics and strategy

Policy simulation and agent-based modelling

Some decisions cannot wait for an evaluation, because the policy does not exist yet. Simulation lets you test it first. Agent-based models represent individual households, consumers or producers making decisions under their own budgets and constraints. Market-level outcomes then emerge from those decisions rather than being assumed.

Questions this answers

  • If household incomes rose by a given amount, how would spending on food, housing or health change?
  • Would a tax, subsidy or price change shift behaviour, and would part of the effect be lost to market price adjustments?
  • Which groups gain or lose under each policy option?
  • How sensitive are the results to the assumptions we are least sure of?

Methods

Agent-based and microsimulation models calibrated to survey and administrative data, scenario design, demand-system estimation, and structured sensitivity analysis. Each model is documented so that its assumptions can be challenged and changed.
