Working Paper
Optimal disclosure policy and undue diligence

While both public and private financial agencies supply asset markets with large amounts of information, they do not generally disclose all asset-related information to the general public. This observation leads us to ask what principles might govern the optimal disclosure policy for an asset manager or financial regulator. To investigate this question, we study the properties of a dynamic economy endowed with a risky asset, and with individuals that lack commitment. Information relating to future asset returns is available to society at zero cost. Legislation dictates whether this ...

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.

What is the Value of Being a Superhost?

We construct a search model where sellers post prices and produce goods of unknown quality. A match reveals the quality of the seller. Buyers rate sellers based on quality. We show that unrated sellers charge a low price to attract buyers and that highly rated sellers post a high price and sell with a higher probability than unrated sellers. We fi nd that welfare is higher with a ratings system. Using data on Airbnb rentals, we show that Superhosts and hosts with high ratings: 1) charge higher prices, 2) have a higher occupancy rate and 3) higher revenue than average hosts.

Liquidity Premiums on Government Debt and the Fiscal Theory of the Price Level

We construct a dynamic general equilibrium model where agents use nominal government bonds as collateral in secured lending arrangements. If the collateral constraint binds, agents price in a liquidity premium on bonds that lowers the real rate on bonds. In equilibrium, the price level is determined according to the fiscal theory of the price level. However, the market value of government debt exceeds its fundamental value. We then examine the dynamic properties of the model and show that the market value of the government debt can fluctuate even though there are no changes to current or ...

Channel systems: Why is there a positive spread?

An increasing number of central banks implement monetary policy via two standing facilities: a lending facility and a deposit facility. In this paper we show that it is socially optimal to implement a non-zero interest rate spread. We prove this result in a dynamic general equilibrium model where market participants have heterogeneous liquidity needs and where the central bank requires government bonds as collateral. We also calibrate the model and discuss the behavior of the money market rate and the volumes traded at the ECB?s deposit and lending facilities in response to the recent ...

Money, Banking and Financial Markets

The fact that money, banking, and financial markets interact in important ways seems self-evident. The theoretical nature of this interaction, however, has not been fully explored. To this end, we integrate the Diamond (1997) model of banking and financial markets with the Lagos and Wright (2005) dynamic model of monetary exchange?a union that bears a framework in which fractional reserve banks emerge in equilibrium, where bank assets are funded with liabilities made demandable in government money, where the terms of bank deposit contracts are affected by the liquidity insurance available in ...

Working Paper
Monetary policy with asset-backed money

We study the use of intermediated assets as media of exchange in a neo- classical growth model. An intermediary is delegated control over productive capital and finances itself by issuing claims against the revenue generated by its operations. Unlike physical capital, intermediated claims are assumed to be liquid-they constitute a form of asset-backed money. The intermediary is assumed to control 1) the number of claims outstanding, 2) the dividends paid out to claim holders and 3) the fee charged for collecting the dividend. We find that for patient economies, the first-best allocation can ...

Working Paper
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.

Working Paper
Optimal stabilization policy with endogenous firm entry

Monetary policy has significant but overlooked effects on entry and exit of firms. We study optimal monetary stabilization policy in a DSGE model with microfounded money demand and endogenous firm entry. Due to a congestion externality affecting firm entry, the optimal policy deviates from the Friedman rule in all states even though all prices are fully flexible. In contrast to previous Ramsey model with flexible price, our calibration exercises suggest that the model can generate a high volatility of the nominal interest rate which is a direct consequence of policy actions to control entry.

Working Paper
Monetary policy in a channel system

Channel systems for conducting monetary policy are becoming increasingly popular. Despite its popularity, the consequences of implementing policy with a channel system are not well understood. The authors develop a general equilibrium framework of a channel system and study the optimal policy. A novel aspect of the channel system is that a central bank can "tighten" or "loosen" its policy without changing its policy rate. This policy instrument has so far been overlooked by a large body of the literature on the optimal design of interest-rate rules.
