Algorithmic trading, what if it is just an illusion?

We experimentally investigate whether and how the potential presence of algorithmic trading (AT) in human-only asset markets can influence humans’ price forecasts, trading activities and price dynamics. Two trading strategies commonly employed by high-frequency traders, spoofing (SP) – associated with market manipulation – and market making (MM) – seen as liquidity provision – are considered. These experiments reveal that, first, the mere expectation of SP traders can, at first, impair price convergence towards fundamentals. Second, the expected presence of AT, especially MM traders, induce larger initial price forecasts deviations from fundamentals. Third, despite the absence of AT in our experiments, the information about the presence of AT, employing MM strategy, is sufficient to alter subjects trading behavior over time and the impact of past realized prices on subjects’ order prices.

Less marketing for a better world !

Marketing seems to be slow to fully recognize its role, place and responsibility in changes in climate, biodiversity and resources. This reluctance can be attributed, at least in part, to the implicit assumptions of sustainable marketing, which tend to minimize the scale of the paradigm shifts needed to remain hopeful of a habitable planet. Consequently, the dominant approaches to “sustainable marketing” find it difficult to question the fundamental principles and ideological foundations of the market system. This is why we are calling for radical changes in marketing research in order to envisage a truly sustainable future. We are therefore formulating a program based on five proposals with the aim of inviting profound transformations in the discipline.

What the Experiences of Young Doctors in Management Tell Us

We consider the doctoral thesis as a tool to develop skills and expand the expertise of doctoral students. We identify two fundamental roles related to the thesis, namely that of emancipator and that of utilitarian, which are perceived as being in tension and competition. Textual analysis of the chapters also revealed the importance of the thesis implementation environment in promoting the development of skills and the action capacities of doctoral students.

What is the Initial Coin Offering?

An Initial Coin Offering (ICO) is a modern fundraising method for start-ups, similar to crowdfunding but using digital tokens instead of traditional cash or rewards. Investors purchase these tokens, which they can later use to buy the product or resell for potential profit. ICOs provide entrepreneurs with a global financing opportunity while offering investors early access to innovative projects. Overall, ICOs connect entrepreneurship, finance, and blockchain technology, making them a revolutionary tool for start-up funding.

Environmental Tax Policies in Emerging Markets: Does Confidence in Political Institutions Matter?

The goal of this study is to examine how environmental taxes influence the comparative advantage in environmental products and carbon emissions within emerging economies. To gain a better understanding, we examine whether this impact changes depending on the level of government integrity. The results indicate that increased environmental taxes mitigate the comparative advantage in environmental goods for emerging markets. However, for countries with high levels of government integrity, higher environmental taxes enhance their competitive edge in environmental goods. Additionally, our findings show that although a rise in environmental taxes is associated with higher carbon emissions, raising such taxes results in a reduction in carbon emissions for emerging economies with solid government integrity. These findings suggest that robust political institutions are crucial in promoting the comparative advantage of emerging markets in environmental goods and mitigating climate change. In the absence of substantial confidence in political or governmental institutions, the efficient implementation of climate taxes poses considerable challenges. Furthermore, we observe that an increase in the comparative advantage of environmental goods results in a decrease in carbon emissions.

In Machine Learning We Trust: A Bankruptcy Prediction Application

Recently, ensemble-based machine learning models have been widely adopted and have demonstrated their effectiveness in bankruptcy prediction. However, these algorithms often function as black boxes, making it difficult to understand how they generate forecasts. This lack of transparency has led to growing interest in interpretability methods within artificial intelligence research. In this paper, we assess the predictive performance of Random Forest, LightGBM, XGBoost, and NGBoost (Natural Gradient Boosting for probabilistic prediction) on French firms across various industries, with a forecasting horizon of one to five years. We then apply Shapley Additive Explanations (SHAP), a model-agnostic interpretability technique, to explain XGBoost, one of the best-performing models in our study. SHAP highlights the contribution of each feature to the model’s predictions, enabling a clearer understanding of how financial and macroeconomic factors influence bankruptcy risk. Moreover, it allows for the explanation of individual predictions, making black-box models more applicable in credit risk management.

The walking dead: Are Zombie firms environmentally and socially responsible? A global perspective

This study examines the association between zombie firms and their environmental and social performance. Using a global dataset of listed firms from 49 countries between 2002 and 2019, we find that zombie firms perform poorly on environmental and social responsibility fronts. This finding supports the argument that zombie firms are characterized by consistent losses and that their existence is risky without external support. Zombie firms, while struggling for survival, may not be able to undertake environmental and social activities that require huge investments, thus falling behind other firms. Further analysis highlights that eco-innovation, the presence of a sustainability committee, and industry nature (i.e., heavily polluting industries) mitigate the negative impact of firms’ zombie status on their environmental and social performance. Moreover, a zombie firm’s engagement in environmental and social activities improves its financial performance. Our main findings are robust to a battery of estimation techniques, alternative proxies, selection bias, and endogeneity issues.
