This paper derives optimal top tax rate formulas in a model where top earners respond to taxes through three channels: labor supply, tax avoidance, and compensation bargaining. The optimal top tax rate increases when there are zero-sum compensation-bargaining effects. We present empirical...

We examine the effects of presentation and information on the take-up of financial subsidies for retirement saving in a large randomized experiment carried out with H&R Block. The subsidies raise take-up and contributions with larger effects when the subsidy is characterized as a matching...

This paper uses tax return data to analyze bunching at the kink points of the US income tax schedule. We estimate the compensated elasticity of reported income with respect to (one minus) the marginal tax rate using bunching evidence. We find clear evidence of bunching around the first kink...

Recent evidence on the effect of dividend taxes on firm behavior is inconsistent with neoclassical theories of dividend and corporate taxation. We develop a simple agency model in which managers and shareholders have conflicting interests to explain the evidence. In this model, dividend taxation...

We characterize welfare gains from government intervention when the private sector provides partial insurance. We analyze models in which adverse selection, pre-existing information, or imperfect optimization create a role for government intervention. We derive formulas that map existing...

Connecting private dwellings to the water main is expensive and typically cannot be publicly financed. We show that households' willingness to pay for a private connection is high when it can be purchased on credit, not because a connection improves health but because it increases the time...

Participation of beneficiaries in the monitoring of public services is increasingly seen as a key to improving their quality. We conducted a randomized evaluation of three interventions to encourage beneficiaries' participation to India: providing information on existing institutions, training...
