In an endowment economy, we analyze coexistence and competition between traditional fiat money (Dollar) and cryptocurrency (Bitcoin). Agents can trade consumption goods in either currency or hold on to currency for speculative purposes. A central bank ensures a Dollar inflation target, while...

We argue that long-run inflation has nonlinear and state-dependent effects on unemployment, output, and welfare. Using panel data from the OECD, we document three correlations. First, there is a positive long-run relationship between anticipated inflation and unemployment. Second, there is also...

Is asset liquidity a source of price volatility? We answer this question within a continuous-time, New Monetarist economy under extrinsic uncertainty and endogenous asset liquidity. We consider single or multiple assets, risk-free or risky assets, assets that have a positive intrinsic value, no...

This paper introduces an empirical measure of the cost of allocating money market volatility between the money stock and the Federal funds rate, the principal purpose being to devise a framework for data-based measures of the short-run implied by alternative operating procedures

The persistent nature of equity volatility is investigated by means of a multi-factor stochastic volatility model with time varying parameters. The parameters are estimated by means of a sequential matching procedure which adopts as auxiliary model a time-varying generalization of the HAR model...

In this paper we develop a general framework to analyze state space models with timevarying system matrices where time variation is driven by the score of the conditional likelihood. We derive a new filter that allows for the simultaneous estimation of the state vector and of the time-varying...
