The current study aims to investigate the mediating role of executive stock options in the nonlinear relationship between financial constraints and research and development (R&D) investment through two measures of financial constraints.

This study is based on a sample of 90 French firms for the period extending from 2008 to 2020. The authors employ a panel threshold method to analyze whether the impact of financial constraints on R&D investment depends on the level of financial constraints or not.

Using SA index (Hadlock and Pierce, 2010) and FCP index (Schauer et al., 2019) as measures of financial constraints, the authors demonstrate that the relationship between financial constraints and R&D investment is nonlinear. Moreover, the authors find that executive stock options mediate partially the relationship between financial constraints and R&D investment. More specifically, the authors show that stock options could play two roles depending on the level of the financial constraints; inconsistent mediation for firms with low/medium level of financial constraints and partial mediation for highly constrained firms.

This paper is the first to the best of the authors' knowledge to investigate the nonlinear relationship between financial constraints and R&D investment as well as the mediating role of executive stock option using dynamic panel threshold models.

The purpose of this study is to examine the nonlinear relationship between financial constraints and the chief executive officer (CEO) stock options compensation and to analyze whether the impact of financial constraints on the CEO stock options compensation changes at certain level of financial constraints or not.

This study is based on a sample of 90 French firms for the period extending from 2008 to 2019. To deal with the non-linearity, the authors use a panel threshold method.

Using different measures of financial constraints [KZ index (Baker et al., 2003), SA index (Hadlock and Pierce, 2010) and FCP index (Schauer et al., 2019)], the results reveal that the impact of the financial constraints (SA index and FCP index) is positive below the threshold value and it becomes negative above.

The non-linearity between financial constraints and CEO stock options shows that the level of financial constraints can be a major determinant of the CEO compensation structure. More specifically, this study sheds light on the key role played by the level of financial constraints and how this latter influence management decisions.

This paper is the first to the best of the authors' knowledge to examine the nonlinear relationship between financial constraints and the CEO stock options compensation using a panel threshold model.

This paper explores whether the Euro-area sovereign credit default swap market is prone to contagion effects. It investigates whether the sharp increase in sovereign CDS spread of a given country is due to a deterioration of the macroeconomic variables or some form of contagion.

For this purpose, the authors use an innovative approach, i.e. spatial econometrics. Although modeling spatial dependence is an attractive challenge, its application in the field of finance remains limited.

The empirical findings show strong evidence of spatial dependence highlighting the presence of pure contagion. Furthermore, evidence of wake-up call contagion-increased sensitivity of investors to fundamentals of neighboring countries and shift contagion-increased sensitivity to common factors are well recorded.

This study aims to study a crucial financial issue that gained increased research interest, i.e. financial contagion. A methodological contribution is made by extending the standard spatial Durbin model (SDM) to analyze and differentiate between several forms of contagion. The results can be used to understand how shocks are spreading through countries.

This study aims to explore the failures of Tunisian secondary corporate bond market liquidity to understand the determinants of corporate bond market liquidity at large.

We adopted a qualitative approach to studying the Tunisian Stock Exchange. Dealers’ perceptions were collected through semi-structured face-to-face interviews; the data was recorded, transcribed and thematically analysed.

Secondary corporate bond market failures are due, in part, to microstructural choices – especially the use of an over-the-counter market as a trading venue. The absence of a corporate bond yield curve, a narrow investor base, market participants’ lack of financial education and authorities’ attitudes are equally responsible.

This study is useful to researchers, policymakers and practitioners, as it identifies microstructural and other factors affecting the Tunisian secondary corporate bond market. We interviewed only Tunisian dealers while ignoring other categories of market participants. Furthermore, a focus group discussion could have improved our understanding of the determinants of the Tunisian secondary corporate bond market.

This paper aimed to qualitatively discuss several issues related to the Tunisian secondary corporate bond market. To date, little academic research has addressed this topic in the illiquid and non-transparent corporate bond markets.

The purpose of this study is to examine the relationship between stock options compensation and firm strategic risk-taking, employing a quantile regression (QR) model. This study aims to analyze whether the impact of stock options on firm strategic risk-taking changes across various quantiles and investigates the moderating role of firm performance.

This study is based on a sample of 90 French firms for the period extending from 2008 to 2019. To deal with the non-uniform association, the authors use a panel quantile method.

The results reveal that the impact of chief executive officer (CEO) stock options on firm strategic risk-taking varies across risk-taking quantiles. More specifically, the study’s results show a positive association at low quantile levels of strategic risk-taking, measured by research and development (R&D) and a negative linkage at high levels. The authors also find that firm performance moderates the impact of CEO stock options on strategic risk-taking.

The non-uniform relationship between CEO stock options and firm strategic risk-taking shows that the weight of CEO stock options in the total compensation can be a major determinant of the firm's strategic risk-taking attitude.

This study extends existing research on executive compensation and strategic risk-taking. Thus, this study has the potential to help stakeholders, board of directors and regulators, who are attempting to understand how the compensation contract – in particular, stock option pay – is related to the risk behavior of the agents and guide them to structure the executive compensation in an optimal way.
