We analyze the effects of taxation in two-sided matching markets where agents have heterogeneous preferences over potential partners. Our model provides a continuous link between models of matching with and without transfers. Taxes generate inefficiency on the allocative margin, by changing who...

We analyze the value of insurance when individuals have access to credit markets. Loans allow consumers to smooth financial shocks over time, decreasing the value of consumption smoothing from insurance. We derive formulas for the value of insurance that can be taken to data, and show how that...

Policymakers subsidizing health insurance often face uncertainty about future market prices. We study the implications of one policy response: linking subsidies to prices, to target a given post-subsidy premium. We show that these price-linked subsidies weaken competition, raising prices for the...

Subsidies in many health insurance programs depend on prices set by competing insurers -- as prices rise, so do subsidies. We study the economics of these "price-linked" subsidies compared to "fixed" subsidies set independently of market prices. We show that price-linked subsidies weaken price...

We study the implications of one policy response: linking subsidies to prices, to target a given post-subsidy premium.

Health insurers increasingly compete on their covered networks of medical providers. Using data from Massachusetts' pioneer insurance exchange, I find substantial adverse selection against plans covering the most prestigious and expensive "star" hospitals. I highlight a theoretically distinct...

We analyze the financial value of insurance when individuals have access to credit markets. Loans allow consumers to smooth shocks across time, decreasing the value of the smoothing (across states of the world) provided by insurance. We derive a simple formula for the incremental value of...
