Forward guidance supercharges monetary policy transmission

Shanghai Jiao Tong University Journal Center

A groundbreaking study from New Zealand demonstrates that central bank "forward guidance" significantly strengthens the transmission of monetary policy. Analyzing New Zealand's banking data, the research finds that providing clear communication about the future path of interest rates enhances the pass-through from the official policy rate to bank deposit and lending rates. The results show improved long-term pass-through, especially for time deposits and fixed mortgages, alongside a slight acceleration in short-term adjustments. These findings offer critical evidence for central banks worldwide on the power of communication as a policy tool.

Socially aware AI helps autonomous vehicles weave through crowds without collisions

ELSP
Peer-Reviewed Publication

Researchers from Tongji University and Shanghai Jiao Tong University have developed a socially aware prediction-to-control pipeline that lets autonomous vehicles safely navigate dense crowds by anticipating multiple ways pedestrians might move. Instead of betting on a single forecast, their system combines a Social GAN trajectory predictor with a real-time Model Predictive Control (MPC) planner, treating each predicted path as a moving obstacle. In dynamic crowd simulations, the integrated Social GAN+MPC controller achieved zero safety violations and maintained comfortable motion, all while meeting strict real-time computing limits—offering a practical route toward zero-collision autonomous driving in busy urban environments.

To make AI more fair, tame complexity

University of Texas at Austin
Peer-Reviewed Publication

Biases in AI’s models and algorithms can actively harm some of its users and promote social injustice. Documented biases have led to different medical treatments due to patients’ demographics and corporate hiring tools that discriminate against female and Black candidates.

New research from Texas McCombs suggests both a previously unexplored source of AI biases and some ways to correct for them: complexity.
