Beta Forecasting With Realized Beta Estimators and Machine Learning Algorithms

Journal of Forecasting, EarlyView.
ABSTRACT This paper applies machine learning algorithms to the modeling of realized betas for the purposes of forecasting stock systematic risk. Higher levels of beta forecast accuracy are demonstrated, relative to other studies in the literature. These improvements are also highly significant, both statistically and economically.

A Multi‐Objective Periodic Vehicle Routing Model for Sustainable Healthcare Waste Collection

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT The collection of infectious waste from healthcare facilities (HCF) constitutes a recurring operational challenge. Indeed, despite the inherent health risks posed by the storage and the transportation of infectious materials, most of the existing waste collection systems tends to prioritise cost optimization and to underaddress the safety ...

Researcher–Entrepreneur Relationship and Performance of Innovative Startups

International Journal of Finance &Economics, EarlyView.
ABSTRACT Many innovative startups are joint ventures between researchers and entrepreneurs, who collaborate in R&D and product commercialization. Government policies such as grants, subsidies, and patent licensing fees act as Pigouvian subsidies, incentivizing R&D by bridging the gap between the social and private returns of innovation.

How Is FinTech Shaping Household Portfolio Behaviour?

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines how FinTech adoption influences household portfolio allocation across major advanced economies. Using a flow‐of‐funds framework and the Almost Ideal Demand System (AIDS), we model household demand for currency, deposits, loans, debt securities, and equity in the United States, United Kingdom, Euro Area, Japan and Australia.

Postpartum anemia and maternal wellbeing: A cohort analysis of the WOMAN‐2 trial

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We examined the association between postpartum anemia and maternal wellbeing in women who gave birth with anemia. Methods We conducted a cohort analysis using secondary data from the WOMAN‐2 trial. Between August 2019 and September 2023, women with moderate or severe anemia who were giving birth vaginally were recruited from ...

Central limit theorems for weighted quadratic forms of dependent processes with applications in specification testing [PDF]

In this paper, we establish some new central limit theorems for generalized U-statistics of dependent processes under some mild conditions. Such central limit theorems complement existing existing results available from both the econometrics literature ...

Interpersonal Predictors of Youth Internalizing Symptom Trajectories During the COVID‐19 Pandemic

Journal of Adolescence, EarlyView.
ABSTRACT Introduction The COVID‐19 pandemic disrupted youths' interpersonal relationships, posing risks for internalizing distress. Yet, evidence remains limited beyond the early pandemic waves and with changing interpersonal contexts. This study examined trajectories of youth internalizing symptoms across five timepoints of the pandemic and ...

Two Two‐Tier Stochastic Frontier Replications

Journal of Applied Econometrics, EarlyView.
ABSTRACT We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools.

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Advice taking across social class: Why (and when) high‐SES consumers are more likely to take advice from marketplace agents

Journal of Consumer Psychology, EarlyView.
Abstract The present research investigates whether consumers of low or high socioeconomic status (SES) are more likely to take advice from marketplace agents. Across five studies (and an additional three in the Methodological Details Appendix), including an analysis of the World Values Survey, and across a range of different advice taking contexts, we ...
