The purpose of this paper is to examine the curvilinear relationship between knowledge leadership and knowledge hiding and the moderating role of psychological ownership on influencing the curvilinear relationship.

In total, 403 data were collected from participants in a high-technology company via a two-wave survey. Hierarchical regression analyses were used to test the hypotheses.

Results revealed an inverted U-shaped relationship between knowledge leadership and knowledge hiding. The employees exhibited more knowledge hiding in a moderate level of knowledge leadership than in lower and higher levels of knowledge leadership. Moreover, psychological ownership significantly moderated the curvilinear relationship such that the inverted U-shaped relationship was more pronounced among employees with high psychological ownership.

Employees’ reaction to knowledge leadership may vary from different levels of knowledge leadership. Moreover, organizations should boost employees’ psychological ownership especially for the collective identity that helps them own knowledge as “ours.”

This study extends both the leadership and knowledge management behavior literatures.

The purpose of this paper is to study the capital structure of firms when controlling shareholders decide on the level of debt financing in an environment with poor legal protection.

Theoretically this paper uses a dynamic model to analyze how the controlling shareholder expropriates the firm's benefit through debt financing. Empirically this paper uses a sample of Chinese publicly listed firms from 2004 to 2007, through the method of OLS and panel data, to verify the theoretical predictions.

Theoretically this paper finds that firms with controlling shareholders will take excess debt financing in an environment of controlled interest rate and poor legal protection to minority shareholders. Government intervention exacerbates while controlling shareholder's cash flow rights constrains excess debt financing. The empirical results conclude that the improvement of the legal environment, limiting government intervention, and raising controlling shareholder's cash flow rights will effectively reduce excess debt level, as well as long‐term debt ratio.

First, this paper provides a theoretical model to explain the mechanism of how the ownership structure, legal environment and government intervention interact to impact debt financing. This result also provides a theory to explain the “paradox” in a transitional economy that better legal protection lowers debt level and long‐term debt ratio. Second, this paper provides further evidence on controlling shareholder's expropriation to minority shareholder through debt financing.

The authors wanted to study the antecedents of knowledge hiding from a leadership perspective.

The authors tested two hypotheses on high-tech employees in China. H1 was: “There is a curvilinear relationship between knowledge leadership and knowledge hiding behaviors.” H2 was: “Psychological ownership moderates the inverted U-shaped relationship between knowledge leadership and employees’ knowledge hiding behaviors such that this relationship is more pronounced among employees with high psychological ownership compared to employees with low psychological ownership.”

Results revealed an inverted U-shaped relationship between knowledge leadership and knowledge hiding. Psychological ownership moderates the link between knowledge leadership and knowledge hiding. The inverted U-shaped relationship between knowledge leadership and knowledge hiding was more significant among employees with higher psychological ownership, whereas the inverted U-shaped relationship became weaker among employees with lower psychological ownership.

The paper was significant because previous researchers had not studied the antecedents of knowledge hiding from a leadership perspective.

We investigate herding behavior and explore how risk aversion interacts with herding in a sample of selected sustainability indices. Furthermore, we evaluate volatility co-movements and dynamic and time-varying correlations of two notable indicators: the cross-sectional absolute deviation of returns (CSAD) and the risk aversion index (RAI). Moreover, we explore a spillover mechanism (in the short and long run) of risk aversion to sustainable investing.

Our study uses daily prices from 01/06/2012 to 15/07/2022 obtained from S&P Dow Jones Indices. We use autoregressive - Glosten, Jagannathan, and Runkle generalized autoregressive conditional heteroscedastic (AR(1)-GJR GARCH) methodologies to measure the impact of cross-sectional absolute deviation of returns (CSAD) and risk aversion (RAI) indicators on the conditional variance of selected sustainability indices. Furthermore, we employ dynamic conditional correlation with generalized autoregressive conditional heteroscedasticity, generalized autoregressive conditional heteroscedasticity generalized autoregressive conditional heteroscedasticity mixed data sampling and dynamic conditional correlation with mixed data sampling models to examine any dynamic correlation, spillover volatility effects and the predictability stance of the CSAD and the RAI factors on sustainable investing.

Our empirical outcomes capture no-herding behavior but display herding on the risk aversion indicator. The cross-sectional dispersion of returns positively affects the conditional variance of all selected sustainable markets, besides emerging markets, while the risk aversion factor negatively influences the conditional variance for Europe and the USA. We have identified long-term contagion effects relating to the variability of returns in our sample, with the exception of emerging markets.

The dispersion of returns can predict the swings of long-term volatilities of Nordic and Europe markets, while the risk aversion factor can predict the long-run volatilities of sustainable markets except Nordic.

The current study presents, for the first time in the sustainable finance literature, an empirical analysis of herding and risk aversion in sustainable investment returns over time. Our findings offer valuable insights to fund managers, finance professionals and investors, providing them with an opportunity to proactively manage their portfolios and reduce financial risk by understanding the volatility behavior of sustainable investing. Furthermore, it is crucial to explore and understand how the dispersion of returns and risk aversion interact with sustainable markets for the construction of optimal portfolios.
