Leader‐Follower Dynamics in Shareholder Activism

The Journal of Finance, EarlyView.
ABSTRACT We propose a theory of coordination and influence among blockholders. Privately informed activists time their trades in sequence to lower acquisition costs, prompting a strategic use of order flows: leader activists create trading gains for their followers, ultimately influencing their willingness to bear greater value‐enhancing intervention ...

Unveiling Propriety, Validity and Consensus: A Multi‐level Examination of Legitimacy Following the Global Financial Crisis

Journal of Management Studies, EarlyView.
Abstract Previous work on legitimacy has conceptualized its multi‐level nature, encompassing individual‐level propriety and collective‐level validity. Recently, scholars have introduced the construct of consensus, the degree to which evaluators agree in terms of their propriety beliefs.

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Density‐Valued ARMA Models by Spline Mixtures

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper proposes a novel framework for modeling time series of probability density functions by extending autoregressive moving average (ARMA) models to density‐valued data. The method is based on a transformation approach, wherein each density function on a compact domain [0,1]d$$ {\left[0,1\right]}^d $$ is approximated by a B‐spline ...

Fully Modified GLS Estimation for Seemingly Unrelated Cointegrating Polynomial Regressions

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A new feasible generalized least squares estimator is proposed. Our estimator incorporates (1) the inverse autocovariance matrix of multidimensional errors, and (2) second‐order bias corrections. The resulting estimator has the intuitive interpretation of applying a weighted least squares objective function to filtered data series.

Optimizing Human Resource Conditions for 20‐Year Initial Public Offering (IPO) Survival

Personnel Psychology, EarlyView.
ABSTRACT The entrepreneurship literature emphasizes the importance of imprints founders leave on companies; those imprints can change at transformational events such as the initial public offering (IPO). Prior research has found that objective measures (such as structure or compensation systems) can imprint and predict survival post IPO.

Extremism at the center: Uncovering political diversity among midpoint responders on the left–right self‐placement item

Political Psychology, EarlyView.
Abstract The midpoint of the left‐right self‐placement item is hiding important political diversity, and may be conflating moderate responders with populists and other political sub‐groups. Survey researchers should consider this problem when examining relationships between political orientation and political attitudes.
