Are Water Resources Keeping Up with U.S. Economic Needs?
Access to water is necessary to sustain human civilization and agricultural production. Recent analysis finds that most of U.S. land area, economic activity, and agricultural production are in regions with stable to positive trends in local water availability. This provides reassuring news about overall U.S. vulnerability to water resource depletion. However, some Western and Southwestern regions are facing serious water risks that scientists expect to become more severe over time, suggesting that efforts to alleviate this concern should have a regional focus.

The Effects of U.S. Public R&D on Global Growth
This paper provides the first causal estimates of the global social returns to U.S. public R&D. We use a narrative identification strategy to quantify the effects of exogenous shocks to U.S. R&D appropriations on the dynamic TFP response of 69 foreign economies from 1980–2019. A U.S. R&D appropriations shock equal to 1 percent of the federal R&D capital stock raises foreign TFP by approximately 1 percent after 12 years. This response is driven primarily by nondefense rather than defense R&D and is concentrated in non-OECD economies. These patterns are most consistent with diffusion ...
