Dual-currency economies as multiple-payment systems
Monetary search models are valuable for studying how a second currency's acceptability arises endogenously in an economy that lacks a stable domestic currency and other more sophisticated payment systems. Search models' basic assumptions (absence of credit, lack of smoothly functioning banking systems, reliance on currency as the sole medium of exchange, and primitive trading environments) are not necessarily consistent with modern financial systems. They do, however, provide good descriptions of transitional and developing economies, particularly in the countries of the former Soviet Union, ...

Money and capital
We revisit classic questions concerning the effects of money on investment in a new framework: a two-sector model where some trade occurs in centralized and some in decentralized markets, as in recent monetary theory, but extended to include capital. This allows us to incorporate novel elements from the microfoundations literature on trading with frictions, including stochastic exchange opportunities, alternative pricing mechanisms, etc. We calibrate models with bargaining and with price taking in the decentralized market.

Currency competition in a fundamental model of money
The authors study how two fiat monies, one safe and one risky, compete in a decentralized trading environment. The equilibrium value of the two currencies, their transaction velocities and agents' spending patterns are endogenously determined. The authors derive conditions under which agents holding diversified currency portfolios spend the safe currency first and hold the risky one for later purchases. They also examine when the reverse spending pattern is optimal.

Currency portfolios and nominal exchange rates in a dual currency search economy
The authors analyze a dual-currency search model in which agents may hold multiple units of both currencies. They study equilibria in which the two currencies are identical and equilibria in which the two currencies differ according to the magnitude of the "inflation tax" risk associated with each. When one currency has the right amount of risk, equilibria exist in which the safe currency trades for multiple units of the risky one (pure currency exchange). As a result, the steady state has a distribution of nominal exchange rates. The mean and variance of this distribution typically change ...

Bargaining and the value of money
Search models of monetary exchange have typically relied on Nash (1950) bargaining or strategic games that yield an equivalent outcome to determine the terms of trade. By considering alternative axiomatic bargaining solutions in a simple search model with divisible money, we show how this choice matters for important results such as the ability of the optimal monetary policy to generate an efficient allocation. We show that the quantities traded in bilateral matches are always inefficiently low under the Nash (1950) and Kalai-Smorodinsky (1975) solutions, whereas under strongly monotonic ...

Appointing the median voter of a policy board
A description of a model which demonstrates that delegating monetary policy to an independent policy board with discretionary powers substantially reduces policy uncertainty while maintaining political accountability.

On the Essentiality of Credit and Banking at Zero Interest Rates
We investigate the welfare-increasing role of credit and banking at zero interest rates in a microfounded general equilibrium monetary model. Agents differ in their opportunity costs of holding money due to heterogeneous idiosyncratic time-preference shocks. Without banks, the constrained-efficient allocation is never attainable, since impatient agents always face a positive implicit rate in equilibrium. With banks, patient agents pin down the borrowing rate and in turn enable impatient agents to borrow at no cost when the inflation rate approaches the highest discount factor. Banks can ...

What Does the Beveridge Curve Tell Us about the Likelihood of Soft Landings?
Any assessment of the likelihood and characteristics of a soft landing in the labor market should take into account the current state of the labor market and the likely dynamics in the labor market going forward. Modern labor market models centered around the Beveridge curve are a useful tool in this assessment. We use a simple model of the Beveridge curve to investigate what conditions are necessary for a soft landing in the labor market to occur and what the likelihood of these conditions was during the height of the pandemic-period inflation. We find that a soft landing was a plausible ...

What does the Beveridge curve tell us about the likelihood of a soft landing?
Any assessment of the likelihood and characteristics of a soft landing should take into account the situation in the labor market currently and the likely dynamics in the labor market going forward. Modern labor market models centered around the Beveridge curve are a useful tool in this assessment.

The Federal Reserve’s responses to the post-Covid period of high inflation
In the face of the COVID-19 pandemic in March 2020, the Federal Reserve committed to using its full range of tools to support the U.S. economy. Over the next year and a half, with progress on vaccinations and strong policy support, indicators of economic activity and employment strengthened while inflation moved higher. Faced with a tight labor market and elevated inflation, the Federal Open Market Committee (FOMC) began a process of unwinding the very accommodative stance of monetary policy and moving to a restrictive policy stance to address inflation pressures. Here we review the sequence ...
