The success of multi-faceted "graduation" programs at reducing poverty raises three questions: can the impacts of these programs be maintained when implemented by governments at scale, will positive effects be offset by negative spillovers, and can bundled programs be streamlined without losing...

We estimate a multi-country multi-sector New Keynesian model to quantify the drivers of domestic inflation during 2020-2023 in several countries, including the United States. The model matches observed inflation together with sector-level prices and wages. We further measure the relative...

In 2021, the U.S. Treasury reduced Government Sponsored Enterprises (GSEs) exposure to speculative mortgages. As a result, GSE purchases fell by about 20 percentage points. The policy reduced credit to speculative investors in housing, but increased credit to unaffected parts of the...

We study international monetary policy spillovers and spillbacks in a tractable two-country Heterogeneous Agent New Keynesian model. Relative to Representative Agent (RANK) models, our framework introduces a precautionary-savings channel, as households in both countries face uninsurable income...

This paper estimates the degree to which state spending is influenced by the spending of neighboring states. Focusing on mandated increases in welfare spending, I find that each dollar of state spending causes spending in neighboring states to increase by 37 to 88 cents. I use more plausibly...

This paper studies localization of academic and industrial knowledge spillovers. Using data on U.S. Research and Development laboratories, that quantify spatial aspects of learning about universities and firms as well as their locations, I find that academic spillovers are more localized than...

Convergence in per capita income turns on whether technological knowledge spillovers are global or local. Global spillovers favor convergence, while a geographically limited scope of knowledge diffusion can lead to regional clusters of countries with persistently different levels of income per...

Recent empirical work has examined the extent to which international trade fosters international spillovers' of technological information. FDI is an alternate, potentially equally important channel for the mediation of such knowledge spillovers. I introduce a framework for measuring...
