Data visualization is a powerful tool for supporting decision-making. Researchers at the University of Tsukuba systematically reviewed major data visualization research papers from the past 16 years, analyzing their scope using a multidimensional decision-making framework. They found that data visualization primarily supports decision-making at the organizational and community levels. The results provide valuable insights that will foster the development of new visualization technologies and expand their applications in decision support through data visualization.

The stringent environmental regulations in China could potentially be enhancing productivity in the new energy sector, research from Harbin University of Science and Technology and Edith Cowan University (ECU) has found.

This study explores the effectiveness of pair trading strategies within the cryptocurrency market, focusing on three key statistical methods: distance, cointegration, and a novel hybrid approach combining both. Using high-frequency and daily trading data from the top 50 cryptocurrencies on Binance during bullish, stable, and bearish periods from 2020 to 2022, the research conducts a rigorous sensitivity analysis of entry and exit thresholds, as well as portfolio size. The findings demonstrate that pair trading yields substantial profitability, especially on shorter time frames such as 15- and 5-minute intervals. Fixed entry thresholds outperform dynamic ones, while the hybrid approach significantly improves pair selection efficiency. These results offer practical, data-driven guidance for traders, portfolio managers, and fintech professionals seeking to capitalise on the inefficiencies and volatility of the crypto market.

In 2024, the National Association of Realtors paid $418 million to settle an antitrust lawsuit. Part of the settlement gives homebuyers more leverage over their agents’ compensation, potentially lowering the cost of buying a home. But new research from Texas McCombs shows the settlement may not have gone far enough. John Hatfield, professor of finance, suggests more flexible compensation can benefit sellers as well as buyers. He finds that when properties offer lower commissions to buyer agents, those agents tend to steer their clients away from looking at them. 

Five years ago, in the aftermath of the George Floyd murder, Black-founded startups had “a moment” when venture capitalists (VCs) were eager to invest. In the two years after Floyd’s death, the share of VC dollars that went to Black businesses jumped by 43%. Unfortunately for those fledgling companies, and the ones that have followed, that interest and those dollars were short-lived, according to new Cornell research.
