An empirical study that shows that countries’ reserve holdings are sensitive to the rates at which they can borrow on international financial markets, this analysis confirms the view that holding major currencies as reserve assets has costs that are frequently unrecognized. Between 1978-82 for...

This paper analyzes the stochastic inventory control problem when the demand distribution is not known. In contrast to previous Bayesian inventory models, this paper adopts a non-parametric Bayesian approach in which the firm’s prior information is characterized by a Dirichlet process prior....

Building on recent work on the role of speculation and inventories in oil markets, we embed a competitive oil storage model within a DSGE model of the U.S. economy. This enables us to formally analyze the impact of a (speculative) storage demand shock and to assess how the effects of various...

Effective public investment requires governments to address the "recurrent cost problem" to ensure operations and maintenance (O&M) expenditures are sufficient to sustain the flow of productive public capital services to private factors of production. Building on the model of Buffie et al...

We create a network of bilateral correlations of changes in sovereign bond yields and individual bank equity price changes since 2000. We extract some stylized facts from this network of asset price correlations and document the clear differences in asset price correlations between safe havens...

We consider a moral hazard economy in banks and production to study how incentives for risk taking are affected by the quality of supervision. We show that low interest rates may generate excessive risk taking. Because of a pecuniary externality, the market equilibrium may not be optimal and...

The paper examines the joint impact of inflation targeting (IT) and fiscal rules (FR) on fiscal behavior and inflation in a broad panel of advanced and developing economies over the period 1990-2009. The main contribution of the paper is to show that, as suggested by the theoretical literature,...

The global financial crisis highlighted that the financial system can be most vulnerable when it seems most stable. This paper models non-linear dynamics in banking. Small shocks can lead from an equilibrium with few bank defaults straight to a full freeze. The mechanism is based on...
