We propose a simple model to study the efficiency of private liquidity creation by financial intermediaries. Liquidity is provided by both safe and risky debt, and liquidity crises arise when risky debt is defaulted on and stops providing liquidity services. Because of a novel externality...

We propose an integrated treatment of the problems of optimal monetary and fiscal policy, for an economy in which prices are sticky and the only available sources of government revenue are distorting taxes. Our linear-quadratic approach allows us to nest both conventional analyses of optimal...

We would like to propose a new framework for monetary policy analysis that encompasses, as a special case, the Neo-Wicksellian paradigm. A general form of an aggregate-demand equation reveals a role for liquidity, as well as less effective movements in future real rates with respect to current...

We analyze a two-country economy with complete markets, featuring two national currencies as well as a global (crypto)currency. If the global currency is used in both countries, the national nominal interest rates must be equal and the exchange rate between the national currencies is a...

The paper presents a new empirical regularity between the volatility of productivity growth and long-run unemployment, for a given level of long-run productivity growth. A theoretical framework based on asymmetric real wage rigidities is shown to have the potential to rationalize this finding....

Standard discussions of flexible inflation targeting as an optimal monetary policy abstract completely from the consequences of monetary policy for the government budget. But at least some of the countries now adopting inflation targeting have substantial difficulty in controlling fiscal...

This paper provides first and second-order approximation methods for the solution of non-linear dynamic stochastic models in which the exogenous state variables follow conditionally-linear stochastic processes displaying time-varying risk. The first-order approximation is consistent with a...

Asset prices and the equity premium might reflect doubts and pessimism. Introducing these features in an otherwise standard New-Keynesian model changes in a quite substantial way the nature of the policy that maximizes the welfare of the consumers in the model. First, following productivity...

In this research, we provide new empirical evidence on the importance of time-varying uncertainty for the exchange rate and the excess return in currency markets. Following an increase in monetary policy uncertainty, the dollar exchange rate appreciates in the medium run, while an increase in...
