Economists have long been interested in how space – or distance – affects economic activity between buyers and sellers, firms and workers, or global trading partners. But until recently, traditional models have struggled to incorporate spatial complexity, even as more and more data have become available. For Costas Arkolakis, an economics professor at Yale and EGC affiliate, this tension has been a major research motivation.

In a Q&A, Yale’s John Wettlaufer, a foreign member of the Royal Swedish Academy, gives a behind-the-scenes look into the storied scientific tradition.

A new study co-authored by Yale researchers reconstructs the evolutionary relationships among species to find evidence of tree-dwelling primates’ survival.

Public health messaging that emphasizes protecting others’ health is also more effective at promoting the habit in the U.S., a new Yale co-authored study finds.

Yale’s Mark Johnson was recognized by the American Chemical Society for outstanding work in developing new tools to document how chemical reactions occur.

Auction-based water markets, which distribute the greatest amount of water to the highest bidders, have been lauded for their ability to meet demand efficiently. Amid increasing threats of water scarcity, they have become a favored approach in countries like the United States and Australia. However, analyses of water auctions’ efficiency have typically omitted key factors, such as rainfall volatility, sustainability of water supply, and farmers’ liquidity constraints (limitations on their cash to purchase water). In certain contexts, however, other water distribution systems may be more effective.

Outdoors, in the fire extinguisher training station, incoming graduate students hoisted red canisters of carbon dioxide to snuff out flames in a burn pan. Inside, in the pyrophoric reagents station, they witnessed a safe transfer of a highly flammable chemical from one flask to another via a Iuer-syringe and balloons. And at the gas cylinder station, they watched gas escape from a pressure vessel – a potential hazard for fires, explosions, poisoning, and cold or chemical burns.

Yale researchers have found that climate-induced changes to atmospheric rivers could drastically increase extreme precipitation in some parts of the world.

A new Yale study finds that the rise in demonstrations and the subsequent media coverage prompted by the movement had a profound effect on the nation’s youth.

Yale’s Fischer will lead the National Science Foundation’s mission to set national astrophysics science priorities and guide and support ongoing research.
