We claim that political stability, corruption, and women in politics significantly influence CO2 emissions. Using the autoregressive distributed lag approach and an extensive dataset that represents more than 145 countries worldwide, we provide strong and robust evidence that low corruption practices and women's representation in politics statistically and economically reduce carbon emissions. We also show that high political stability significantly reduces CO2 emissions in the short run, but not in the long run. Our findings highlight the importance of these factors in reducing pollution worldwide and provide incentives for international regulators and policymakers toward stronger and mandatory decisions that positively evolve less politically stable and corrupt countries.},

The findings also demonstrate that rank-up and high-polluting firms continually increased their efforts to be sustainable, which increased the positive effect of carbon performance on firm value.

Corporate social responsibility and earnings quality in family firms Journal Article

volume = {23},
number = {5},
pages = {1114-1134},
abstract = {The purpose of this paper is to investigate the relationship between corporate social responsibility and earnings quality, specifically in family firms.
Design/methodology/approach
Based on a sample of French-listed firms from the period 2005 to 2016, the authors use the instrumental variable approach based on a two-stage least-squares (2SLS) estimator.
Findings
The results show that Corporate Social Responsibility (CSR) performance is positively associated with the relevance and faithful representation of earnings. This means that companies that commit to CSR activities are more likely to provide high earnings quality. The results also show that the positive association between CSR performance and earnings quality is more prevalent in family firms suggesting that socially responsible family firms are willing to preserve their socio-emotional wealth by disclosing high quality earnings.
Research limitations/implications
The results suggest that French firms commit to CSR to satisfy the interests of their stakeholders by disclosing high-quality information supporting the conflict resolution view of CSR. The findings also support the socio-emotional wealth perspective and suggest that family firms that engage in CSR activities provide a rich informational environment through high earnings quality.
Practical implications
This study's findings can be thus useful to investors for their portfolio management decisions by enabling them to identify the profile of companies with high earnings quality. These results may also help standard-setters and capital-market regulators improve market transparency by introducing new requirements to encourage investing in CSR.
Originality/value
This study extends the research on the relationship between CSR and earnings quality by focusing on two fundamental characteristics including relevance and faithful representation. This paper focuses on the effect of CSR on earnings quality in the specific context of family firms. This study offers then a better understanding of whether socially responsible family firms communicate stronger or weaker earnings quality than non-family firms based on the agency and socio-emotional wealth perspectives.},

abstract = {We assess the corporate performance and corporate governance consequences of mandatory employee board representation through a natural experiment: the passage of the 2015 Rebsamen law in France, which requires 1 or 2 board seats to be allocated to employee representatives. We hypothesize that such formal institutional arrangements to give workers a voice in corporate governance are irrelevant for family firms, which have been shown to commit to implicit contracts with their employees. We find evidence that affected family firms' share prices reacted negatively to the passage of the law. Moreover, standard OLS regressions of operating performance suggest that family control neutralizes the positive effect associated with employee directors. A more sophisticated difference-in-differences approach shows that affected family firms experienced a significant subsequent decrease in their return on assets. Our investigations of board composition also suggest that family firms rely on avoidance strategies to offset the influence of employee representatives. Overall, this paper casts doubt on the efficiency of minority worker representation in the boardrooms of family-owned companies and thus cautions against a ?one-size-fits-all? approach to corporate governance practices.},

We find that the algorithm produces a semantically meaningful set of topics, which significantly improves the model performance in identifying successful projects. The most value-relevant topics concern the technical features of the ICO. However, we find that white paper's informativeness substantially diminishes after the token is listed. Moreover, we show that credibility-enhancing mechanisms (i.e., regulations and ICO analysts) reinforce the information value of ICO white papers. Overall, our results suggest that the topics discussed in white papers and the attention devoted to each topic are useful ICO performance indicators.},

The results show that dynamic sequential ambidexterity promotes higher firm performance than balanced or simultaneous forms of ambidexterity. Alternating pursuit of exploitation and exploration characterized by a regular frequency of change over time enhances corporate investors' financial performance. The results suggest that CVC firms develop additional expertise in pursuing both exploitation and exploration activities over time which helps to enhance their performance. The findings also show that in times of crisis, the combined use of both exploration and exploitation in CVC investments enables firms to enhance their financial performance. The results are robust to alternative measures of financial performance and to endogeneity concerns.

Based on a copula approach, the results show that all studied markets are affected by the COVID-19 outbreak and the presence of financial contagion for all American and Asian countries. The results also show that contagion is more intense for American countries than Asian ones. These findings have practical implications, especially for investors, risk managers, and policy makers. The latter should continue to provide liquidity to the international market during this pandemic.},

Based on an international sample of 41,535 firm-year observations from 2005 to 2018, the results show that tax avoidance negatively affects the value of excess cash. This negative effect is only prevalent for firms operating in countries with strong investor protection. This study also explores the role of economic policy uncertainty and shows that tax avoidance lowers the discount on the value of excess cash in uncertain times because investors may underestimate any negative reputational and risky practices. These findings have important implications for investors, policymakers and the welfare of the overall economy.},

However, none have investigated how this effect is driven. This study examines whether earnings quality is an effective channel through which the IFRS can mitigate the level of information asymmetry. Based on a sample of French listed companies, we find that information asymmetry decreases significantly after the adoption of IFRS. Using a path analysis and maximum likelihood estimations, the results show that the faithful representation component of earnings quality is the only channel through which IFRS decrease the level of information asymmetry. This finding suggests that the faithful representation of earnings increased under IFRS regulation, which, in turn, enhanced the quality of the informational environment. Our findings are robust using several sensitivity analyses.},

We then delve deeper and examine the mechanisms by which we measure if access to investors' complementary resources has an influence on the innovation performance of the companies they fund. Our sample consists of 1547 U.S. biotechnology companies founded between 1998 and 2013 and financed by IVC or CVC funds. We find that CVC-backed companies display higher rates of innovation output, as measured by their patenting outcomes, than their IVC-backed counterparts. We specify three mechanisms that affect the influence of complementary resources of corporate investors compared to those of IVC: (1) absorptive capacity enhances the ability of the company to grasp and utilize investor knowledge; (2) business similarity helps nurture the technologies of innovative companies, and (3) geographic proximity enables approachability.},

Relying on a large international dataset of approximately a million daily observations over the period 2011-2020 from nine countries (Canada, France, Germany, Japan, Russia, South Korea, Switzerland, the UK, and the US), we find that this recent measure of institutional investor attention has a strong positive effect on stock volatility and liquidity. Confirmed by a battery of robustness tests, our findings suggest that this continuous barometer of attention by institutional investors can be used by financial practitioners to predict future stock volatility and liquidity.},

We propose a different approach based on convex duality instead of martingale measures duality: The prices are expressed using Fenchel conjugate and bi-conjugate without using any no-arbitrage condition. The super-hedging problem resolution leads endogenously to a weak no-arbitrage condition called Absence of Instantaneous Profit (AIP) under which prices are finite. We study this condition in detail, propose several characterizations and compare it to the usual no-arbitrage condition NA.},

Based on a sample of weekly returns on 1,850 U.S. firms over the period 2012â??2020, our econometric estimations report a positive relationship between investor attention to FFD and excess stock returns for U.S. fossil fuelâ??related firms. Therefore, contrary to what the FFD campaigners might expect, the stigmatization of the fossil fuel industry does not drive down the stock returns on fossil fuelâ??related firms.},

Under this framework, we analyze the empirical ability of our model to capture the spread dynamics of three different Investment-grade US Corporate bonds indexes. Our findings show that when compared to the Benchmark, our model improves the empirical performance reducing the yield spread mispricing by 35%, 37%, and 29% for the High grade, Upper medium grade, and Lower medium grade index, respectively.},

abstract = {Globalization is a complex phenomenon, best represented by a general framework in which all financial markets and some goods markets adjust quickly, while for the other goods markets prices vary across countries. We consider a two-period financial model. In the first period, agents consume, buy and sell financial assets to diversify their portfolios. In the second period, they spend their endowments and financial gains to purchase con- sumption goods. We define the concept equilibrium ?, in which the total nominal value of trade is balanced and, for any non-negative individualized system of prices, the total nom- inal value of demand does not exceed the total value of supply. This equilibrium ?coincides with the standard concept of equilibrium when the Law of One Price (LOP) is satisfied for any country. In this model, we introduce imperfect international trade. Assuming that Un- covered Interest (rate) Parity (UIP) holds in all financial markets and the LOP does not hold in some goods markets, we prove that an equilibrium ?does exist; for markets in which the LOP fails, however, the equilibrium becomes autarkic. This result explains why finan- cial markets and some goods markets are globally integrated, while trade fails in other markets. The world economy is fully globalized only if the LOP holds everywhere.},

Up to a threshold, bad news is released to investorsall at once, leading to a drop in the stock prices. We also find that analysts' coverage mitigates the effect of powerfulmanagers on SPCR in widely held firms. However, the relationship between the power of controlling shareholders andSPCR is less prevalent in companies with independent boards. These findings highlight the importance of efficientgovernance devices to curb opportunistic decision-makers and protect the interests of external shareholders.

We find that, during crisis periods, low quality and low liquidity stocks experience relatively higher losses than predicted in normal times, while high quality and high liquidity stocks experience rather relatively lower losses. These findings lend strong support to the presence of cross-market and within-market flight-to-quality and to-liquidity episodes during crisis periods. During low volatility periods, however, low quality and low liquidity stocks earn relatively larger returns, while high quality and high liquidity stocks yield lower returns; suggesting that low volatility conditions benefit junk and illiquid stocks but not quality and liquid stocks. Finally, our results reveal that liquidity level dominates liquidity beta in explaining stock returns across the different market volatility regimes.},

abstract = {This paper demonstrates the impact of the participation of CVC, IVC, and CVC-IVC syndicated investments on the overall concentration of investors involved in syndications. We examine the dynamics of the impact of these syndications and the channels (industry fit and location fit) that improve innovation effectiveness. Based on the main sample of 1017 ventures between 2010 and 2019, there is strong evidence of an existing superiority of CVC engagement in syndications that can further boost the innovation output contribution. Additionally, the results show that industry and location fit augment the innovation output of the venture.},

abstract = {We investigate the impact of family control on both the share price level and the decision to split the firm's stock. Low stock prices are associated with higher volatility and have been shown to attract more speculative trading, which may force managers to excessively focus on short-term earnings. Moreover, a reduction in the stock price level can hurt the firm's reputational capital. We hypothesize that family owners, who are typically long-term investors and are especially concerned about corporate reputation, prefer to set higher stock prices to mitigate short-termism, focus on long-term planning, and reinforce the firm's image. Using a comprehensive sample of firms in the Société des Bourses Françaises (SBF) 120 Index from 1998 to 2016, we find a positive correlation between share prices and family control. Our investigations also indicate that family firms are less likely to conduct price reductions through stock splits. These findings suggest that a high stock price is a distinctive feature of family firms and that family owners have a specific norm in mind with respect to prices.},

abstract = {This paper examines the effect of family control on corporate social responsibility (CSR) in French-listed companies. Based on quantile regressions, our results show that family identity and involvement in capital and management positively influence CSR performance, particularly for low-CSR firms. These findings support the socio-emotional perspective of family firms. However, families with excess control engage less in CSR activities for expropriation purposes. Additional analysis shows that board size and gender diversity attenuate the negative effect of excess family control on CSR performance and help then mitigating the expropriation risk by family-controlled firms.},

abstract = {Among the existing measures of heart rate variability (HRV), the pNN50 statistics is one of the most commonly reported. However, it is only a single member of a much larger family of HRV measures - the pNN statistics. In this research pNN was further extended, combining it with the Lempel-Ziv complexity (LZ76) in a controlled neonatal stress framework. Two different types of stress stimuli on forty healthy newborns - a routine heel stick blood sampling, and a dull heel pressure stimulation - were considered by recording time intervals between heartbeats. Instead of relying on a single value, the entire spectrum from pNN1 to pNN100 was calculated, along with LZ76 derived from binarized sequences for each NN. The results of this study show a downward shift of the pNN curves when newborns are stressed, with reduced LZ76 complexity when stressed. When ROC curves were utilized for the pNN statistics and LZ76, however, the highest AUC values were observed when both measures were combined, with the highest AUC values of 0.88 (0.80-0.94) and 0.85 (0.74-0.91) for discriminating resting states from stress phases. Combining the widely used pNN statistics with LZ76 extends the existing HRV toolbox, and shows a promising application in recognizing acute neonatal stress.},

abstract = {We examine the impact of undervaluation on a firm's use of trade credit. To address potential endogeneity bias, we construct our instrumental variable based on mutual fund outflow-driven price pressure, and our undervaluation measure allows us to distinguish misvaluation from fair valuation. We find that a firm's suppliers play an important role in providing temporary bridge financing when the firm is undervalued. The effect varies with the firm's information environment and with its dependence on external finance. In addition, based on a manually matched supplier-customer sample, we show that small customers in long-term relationships with their suppliers are more likely to obtain trade credit when facing stock market undervaluation, while small suppliers with a smaller customer pool extend more trade credit to their undervalued customers.},
