Lost in Translation? Risk‐Adjusting RMSE for Economic Forecast Performance

Journal of Forecasting, EarlyView.
ABSTRACT When used for parameter optimization and/or model selection, traditional mean squared error (MSE)–based measures of forecast accuracy often exhibit a weak or even negative correlation with the economic value of return forecasts measured by, for example, the Sharpe ratios of the resulting portfolios.

Forecasting With Dynamic Factor Models Estimated by Partial Least Squares

Journal of Forecasting, EarlyView.
ABSTRACT Dynamic factor models (DFMs) have found great success in nowcasting and short‐term macroeconomic forecasting when incorporating large sets of predictive information. The factor loadings are typically estimated cross‐sectionally with principal component analysis (PCA) or maximum likelihood (ML), which ignore whether the factors have predictive ...

Practice adoption in MNCS: A multi‐level interactionist model of trait activation

Global Strategy Journal, EarlyView.
Abstract Research Summary Sharing knowledge through organizational practices is an important source of advantage for multinational corporations (MNCs). While prior research on practice adoption by subsidiaries of MNCs has identified several individual and organizational factors, this study examines their interplay in the context of HQ‐mandated ...

How Signals of Silence Sustain Sexual Harassment and What to Do About It

Human Resource Management, EarlyView.
ABSTRACT Sexual harassment has persisted for decades as an open secret within organizations, creating an ongoing challenge for Human Resource practitioners. Many employees experience or witness harassment yet say nothing. When they contemplate complaining, they are discouraged from doing so. Some still muster the courage to speak out about these abuses,

The Impact of the 2016 EU Audit Reforms, Oversight, and Corruption on Earnings Management: Evidence From European Banks Using a Dynamic Panel Approach

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study investigates earnings management in European banks in the context of the 2016 EU audit directive. Using a dynamic panel of 134 banks over 2012–2023, we apply two‐step System‐GMM estimators with three profitability measures—Earnings Before Provisions and Taxes (EBPT), Return on Assets (ROA), and Return on Equity (ROE).
