Outside versus inside bonds: a Modigliani-Miller type result for liquidity constrained economies
When agents are liquidity constrained, two options exist - sell assets or borrow. We compare the allocations arising in two economies: in one, agents can sell government bonds (outside bonds) and in the other they can borrow (issue inside bonds). All transactions are voluntary, implying no taxation or forced redemption of private debt. We show that any allocation in the economy with inside bonds can be replicated in the economy with outside bonds but that the converse is not true. However, the optimal policy in each economy makes the allocations equivalent.

Demographics, redistribution, and optimal inflation
The authors study the interaction among population demographics, the desire for intergenerational redistribution of resources in the economy, and the optimal inflation rate in a deterministic life cycle economy with capital. Young cohorts initially have no assets and wages are the main source of income; these cohorts prefer relatively low real interest rates, relatively high wages, and relatively high rates of inflation. Older cohorts work less and prefer higher rates of return from their savings, relatively low wages, and relatively low inflation. In the absence of intergenerational ...

Optimal Taxes Under Private Information: The Role of the Inflation
We consider an overlapping generation framework with search and private information to study optimal taxation. Agents sequentially trade in markets that are characterized by different frictions and trading protocols. In frictional decentralized markets, agents receive shocks that determine if they are going to be consumers or producers. Shocks are private information. Mechanism design is used to solve for the constrained optimal allocation. We then study whether a government can replicate the constrained optimal allocation with an array of policy instruments including fiat money. We show that ...

Price level targeting and stabilization policy
We construct a dynamic stochastic general equilibrium model to study optimal monetary stabilization policy. Prices are fully flexible and money is essential for trade. Our main result is that if the central bank pursues a price-level target, it can control inflation expectations and improve welfare by stabilizing short-run shocks to the economy. The optimal policy involves smoothing nominal interest rates which effectively smooths consumption across states.
