Charging infrastructure reliability and accessibility remain significant impediments in the transition to electric vehicles (EVs). While the Bipartisan Infrastructure Law included substantial investments to expand the charging network, potential EV buyers often struggle to determine whether chargers are functioning and available when needed. In Charging Uncertainty: Real-Time Charging Data and Electric Vehicle Adoption (NBER Working Paper 33342), researchers Omar Isaac Asensio, Elaine Buckberg, Cassandra Cole, Luke Heeney, Christopher R. Knittel, and James H. Stock examine how improving real-time charging data availability could affect EV adoption rates...

From an asset market perspective, there are three main drivers of variation in the dollar exchange rate. First, foreign investors value dollars more if dollar investments pay out higher interest rates than abroad. This is the interest rate channel. Second, foreign investors value dollars more if the dollar appreciates when volatility in global financial markets spikes. In this case, the dollar offers protection against increases in global volatility, and foreign investors are willing to accept a negative excess return on dollar assets, the equivalent of paying an insurance premium to hold the dollar. This is the currency risk premium channel. Third, foreign investors value dollars because of the safety and liquidity of dollar-denominated safe assets, such as Treasury bonds. Foreign investors earn extra convenience yields from holding…

Alzheimer's Disease and Related Dementias (ADRD) represent a growing global health crisis, with cases projected to reach 131.5 million by 2050. The economic burden is substantial: In 2020, ADRD cost the United States $305 billion, with forecasts suggesting a threefold increase over the next 35 years in the absence of effective interventions. While previous research has associated lower educational attainment with increased ADRD risk, establishing causality has proved challenging due to potential confounding factors including childhood circumstances, socioeconomic background, and genetic predisposition.

In Education and Dementia Risk (NBER Working Paper 33430), researchers Silvia H. Barcellos, Leandro Carvalho, Kenneth Langa, Sneha Nimmagadda, and Patrick Turley leverage a natural experiment to investigate...

Immigrants to the US are more entrepreneurial than the native population and overrepresented among high-growth startups and venture-backed tech firms. In Immigrant Entrepreneurship: New Estimates and a Research Agenda (NBER Working Paper 32400), Saheel Chodavadia, Sari Pekkala Kerr, William Kerr, and Louis Maiden use business surveys and administrative employment records to provide new evidence on the prevalence and predictors of immigrant...
