Friedman meets Hosios: efficiency in search models of money
In this paper the authors study the inefficiencies of the monetary equilibrium and optimal monetary policies in a search economy. They show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades (or search decisions). The Friedman rule eliminates the first inefficiency, and the Hosios rule the second. A monetary equilibrium attains the social optimum if and only if both rules are satisfied. When the two rules cannot be satisfied simultaneously, which occurs in a large set of economies, optimal ...

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.

A Short Introduction to the World of Cryptocurrencies
In this article, we give a short introduction to cryptocurrencies and blockchain technology. The focus of the introduction is on Bitcoin, but many elements are shared by other blockchain implementations and alternative cryptoassets. The article covers the original idea and motivation, the mode of operation and possible applications of cryptocurrencies, and blockchain technology. We conclude that Bitcoin has a wide range of interesting applications and that cryptoassets are well suited to become an important asset class.

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 ...

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 ...

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 ...

On the Negatives of Negative Interest Rates
Major central banks remunerate reserves at negative rates (NIR). To study thelong-run effects of NIR, we focus on the role of reserves as intertemporal stores of value that are used to settle interbank liabilities. We construct a dynamic general equilibrium model with commercial banks holding reserves and funding investments with retail deposits. In the long run, NIR distorts investment decisions, lowers welfare, depresses output, and reduces bank profitability. The type of distortion depends on the transmission of NIR to retail deposits. The availability of cash explains the asymmetric ...
