Machine Learning As Arbitrage: Can Economics Help Explain Ai?, Huahao Lu, Matthew Spiegel, Hong Zhang

Sim Kee Boon Institute for Financial Economics

Machine learning algorithms have shown to be remarkably successful tools for predicting asset returns. However, the underlying economic mechanisms behind their performance remain unclear. This paper proposes a model-based dynamic arbitrage trading strategy that combines economic and statistical nonstationarity to demystify this black box. In predicting stock returns based on 153 firm characteristics (anomalies), our strategy ranks anomalies similarly to neural networks in the cross-section. Overall, it accounts for approximately 87.9 bps monthly alphas of the high-minus-low portfolios selected by neural networks in the time series. When unpublished anomalies and microcap stocks are excluded from trading, this strategy can fully …

Research Report: Civil Discourse, Heather Akin, Cheryl A. Burkhart-Kriesel, Mary Emery, Katelyn Larson, Bradley Lubben, L. J. Mcelravy, Timothy Meyer, Rebecca J. Vogt

Nebraska Rural Poll

Most rural Nebraskans believe the lack of civil or respectful discourse in our political system is either a very serious or a somewhat serious problem. The responses were fairly similar to those received last year.

In addition, most rural Nebraskans think Americans are more divided over politics than they were 10 years ago. The responses are similar to those received last year.

Despite that feeling, most rural Nebraskans have friends who have political views that are very different from their own. Yet, some rural Nebraskans are no longer able to talk to friends or family members because of their views …

Successfully Transferring Ownership And Accountability: Necessary Discussions To Consider, Carol Wittmeyer

Business Faculty/Staff Publications

NSRA’s Next Generation Leadership Program (NextGen) is designed to help independently owned shoe stores transition from one generation to the next. The NextGen Program held prior to the Atlanta Shoe Market in January 2024, focused on preparing the NextGens for important conversations with their NowGens about the succession process. Succession can refer to many transitions including ownership and/or management. Oftentimes in family businesses, those transitions should – but may not – go hand in hand, causing significant issues for everyone involved and risking the successful transition that family firms dream about. The workshop addressed strategies to minimize this frequent disconnect.

Blackleg And Its Management In Canola, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Blackleg, caused by the fungus Leptosphaeria maculans, is the most common and serious disease of canola in Western Australia (WA). Blackleg can cause significant damage by infecting the cotyledons or first leaves early in the season, leading ultimately to crown lesions or cankers later in the season.

Changes in variety choice, crop rotation, earlier sowing times, and stubble retention have extended the risk of blackleg disease. Because of early emergence, later stages of crop growth are more likely to be exposed and infection can occur on all parts of the plant above ground, including canola flowers, stems, and branches (this …

Different Feathers Embedding Together: Integrating Diversity And Organizational Embeddedness, Debjani Ghosh, Jorge A. Gonzalez, Tomoki Sekiguchi

Management Faculty Publications

Despite the increase of demographic diversity in organizational environments, little is known about how and why employees from distinct demographic backgrounds (e.g., gender, race, and/or ethnicity) become embedded in their work organizations, which is a reason why employees stay and perform in their jobs. To address this research gap, we integrate job embeddedness and social identification/self-categorization theories and draw from critical diversity studies to theorize on the effects of varying degrees of demographic diversity on the organizational embeddedness of diverse talent. Specifically, we theorize on how monolithic, pluralistic, and multicultural organizational stages, reflecting distinct degrees of heterogeneity, structural integration, and …

Wheat Streak Mosaic Virus And Wheat Curl Mite And Their Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Wheat streak mosaic virus (WSMV) is a seed and mite-borne virus that infects wheat, causing severe leaf symptoms and reduced yields. The symptoms and damage are more severe in wheat than other hosts, in which infection is symptomless.

Wheat streak mosaic virus can cause crop failure when widespread infection occurs in seedling wheat, particularly when a heavily WSMV-infected green bridge is not controlled before sowing an early crop, and warm temperatures favour mites.

Wheat curl mite (Aceria tosichella) is the only known vector of WSMV. It can transmit the virus in its nymph and adult stages.

Big Data Analytics And Management Forecasting Behavior, Beng Wee Goh, Na Li, Tharindra Ranasinghe

Research Collection School Of Accountancy

This paper investigates whether the use of Big Data analytics by firms has a spillover effect on management forecasting behavior. Insights provided by Big Data could potentially improve firms’ ability to forecast earnings (supply channel) and investor demand for earnings information is likely higher for firms engaging in data analytics (demand channel). Using a text-based measure of firms’ commitments to and usage of Big Data analytics, we find that Big Data analytics usage is positively associated with the propensity to issue management earnings forecasts. Consistent with the “supply channel” explanation, we find that Big Data analytics usage is positively associated …
