Row Crops and the U.S. Agricultural Trade Deficit: Recent Trends and Policy Issues
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Row crops such as soybeans, corn, wheat, and cotton are the backbone of the U.S. farm sector, accounting for around $60 billion of exports in 2023. While U.S. row crop exports remain robust, growing concerns over the rising U.S. agricultural trade deficit underscore the need to appraise the ongoing market and policy dynamics affecting the ...

The Mechanism and Potential Therapeutic Strategies of Vascular Aging
AGING MEDICINE, EarlyView.The phenotypes of vascular aging vary across different blood vessels. Endothelial dysfunction is observable in the endothelium of all vessels, while vascular structural remodeling primarily occurs in arteries. A decline in organ vascular density mainly affects arterioles, venules, and capillaries, whereas thrombosis predominantly occurs in the ...

Agribusiness, EarlyView.Abstract Futures markets are critical to price discovery and often dominate spot markets. We analyze the linkages between daily corn futures and spot prices in the United States using dynamic time warping. This nonparametric pattern recognition technique has several advantages over traditional time series methods.
