This dissertation investigates the impact of various policies on labor supply, household savings, and mortgage debt at the microeconomic level. By analyzing these policies in depth, this dissertation seeks to provide a comprehensive understanding of how these policies affect individual decision-making and broader economic outcomes. Chapter two exploits a natural experiment stemming from a pension system reform and investigates its causal effect on wealth accumulation and transitions from wage-employment to self-employment. Chapter three examines the displacement effects of mandatory occupational pension savings on private household wealth across different groups. Chapter four evaluates the causal effects of this macroprudential policy on wealth accumulation in the form of mortgage prepayments at the micro-household level.
