The Patient Protection and Affordable Care Act (ACA) is the most comprehensive reform of the U.S. medical system in at least 45 years. The ACA transforms the non-group insurance market in the United States, mandates that most residents have health insurance, significantly expands public...

We propose and study properties of several estimators of variance decomposition in the local-projections framework. We find for empirically relevant sample sizes that, after being bias corrected with bootstrap, our estimators perform well in simulations. We also illustrate the workings of our...

The central thesis of this paper is that the management of portfolios incorporating a variety of investment assets does require the use of time and other scarce resources in searching for, collecting, interpreting, and applying relevant information. Accordingly, the returns on these assets would...

We outline a method to provide advice on optimal monetary policy while taking policymakers' judgment into account. The method constructs Optimal Policy Projections (OPPs) by extracting the judgment terms that allow a model, such as the Federal Reserve Board's FRB/US model, to reproduce a...

This paper develops and applies a model of world trade and exchange rates to analyze dynamic interaction of the current account and exchange rate. The model is designed to concentrate on the determination of trade flows, prices and exchange rates for the OECD member countries but it also covers...

This paper analyzes data on a large sample of research and development (R&D) projects documented in the Defense Department's Independent R&O Data Bank, both to provide some stylized facts about R&O investment at the project level and to test the implications of a control-theoretical model...

In an earlier paper, we showed that the value of shadow prices depends on how the government contemplates re- equilibrating the economy to the perturbation associated with any project, except in the extreme case where the government has chosen all policy instruments optimally. Only under...

We use a large project-level dataset to estimate the length of the planning period for commercial construction projects in the United States. We find that these time-to-plan lags are long, averaging about 17 months when we aggregate the projects without regard to size and more than 28 months...

This paper contributes to the understanding of how to maximize the impact of publicly provided climate finance to leverage the private sector. Agencies seeking to promote private investment in support of climate change mitigation and adaptation may have a choice between subsidizing projects or...

This paper develops a general methodology for analyzing shadow wage (and other shadow prices). Our approach is to identify those reduced form relationships describing the economy which are central to the determination of the shadow wage, and use these to obtain simple formulae for the shadow...
