Ład korporacyjny a unikanie zobowiązań podatkowych – porównanie przedsiębiorstw brytyjskich i japońskich
No full textThe present study was designed to determine the relationship between corporate governance and tax avoidance in an international setting. Financial and governance data sourced from the Datastream database for a sample of Japanese and UK firms between 2012 and 2017 are used. First, we examine the direct effect of several corporate governance mechanisms on tax avoidance. Second, we divide the full sample into two groups (common law and code law legal system) to explore the relationship between law, corporate governance, and tax avoidance. We use both univariate and feasible generalized least square (FGLS) regression methods to examine our hypotheses. This study finds that the board size, independent directors, and the presence of women on boards of directors reduce the likelihood of tax avoidance. However, we find an insignificant association between ownership concentration and tax avoidance. Second, it also finds that firms in countries with higher country-level governance engage in less tax avoidance. The results also suggest that the role of corporate governance is more pronounced for firms operating in common law countries than those in code law countries. This manuscript is one of the few studies that examine the relationship between corporate governance and tax avoidance in an international setting with different legal and institutional environment. This relationship differs across the two countries. This paper clearly identifies implications for research, practice, and society. It documents that when a country implements a good system of governance, which targets improving transparency and accountability, it will lead to less corporate tax avoidance.Celem niniejszego artykułu jest zbadanie wpływu ładu korporacyjnego na unikanie zobowiązań opodatkowych w ujęciu międzynarodowym. W badaniu wykorzystano dane finansowe i dotyczące ładu korporacyjnego dla wybranych przedsiębiorstw japońskich i brytyjskich z okresu 2012–2017, pochodzące z bazy danych Datastream. Najpierw zbadano bezpośredni wpływ kilku mechanizmów ładu korporacyjnego na unikanie zobowiązań podatkowych. Następnie dokonano podziału wybranych przedsiębiorstw na dwie grupy (oparte o system prawa zwyczajowego i system prawa kodeksowego), aby zbadać związek między systemem prawa, ładem korporacyjnym, a unikaniem zobowiązań podatkowych. Do weryfikacji sformułowanych hipotez zastosowano zarówno jednoczynnikowe metody regresji, jak i Stosowalną Uogólnioną Metodę Najmniejszych. Kwadratów (FGLS). Badanie wykazało, że wielkość zarządu, występowanie niezależnych dyrektorów oraz obecność kobiet w zarządach, zmniejszają prawdopodobieństwo unikania zobowiązań podatkowych. Zaobserwowano jednak nieistotny związek między koncentracją własności a unikaniem zobowiązań podatkowych. Wykazano również, że przedsiębiorstwa w krajach o wyższym poziomie zarządzania na szczeblu krajowym są mniej podatne na unikanie zobowiązań podatkowych. Wyniki sugerują też, że rola ładu korporacyjnego jest większa w przypadku firm działających w krajach opartych o system prawa zwyczajowego niż w krajach opartych o system prawa kodeksowego. Opracowanie jest jednym z nielicznych badań, które badają związek między ładem korporacyjnym a unikaniem zobowiązań podatkowych w ujęciu międzynarodowym, z uwzględnieniem różnic w otoczeniu prawnym i instytucjonalnym. Związek ten jest różny w zależności od kraju. W tym artykule wyraźnie wskazano implikacje dla badań naukowych, praktyki i społeczeństwa. Wykazano w nim, że wdrożenie przez państwo prawidłowego systemu zarządzania, którego celem jest poprawa przejrzystości i odpowiedzialności, umożliwia ograniczenie unikania zobowiązań podatkow przez przedsiębiorstwa

A One-Way Car-Sharing Based Approach for Combined Shared Mobility of Freight and Passengers
No full textClimate change stresses the need for research and development of innovative sustainable mobility solutions that provide reliable and convenient door-to-door services for both passengers and freight. The increase in urban population and the popularity of e-commerce further highlights the need for action. In this regard, crowd-shipping is often perceived as an efficient, cost-effective, and sustainable alternative (or complement) to the management of urban freight mobility through efficient utilization of current transportation capacities. In this framework, inspired by the concept of MaaS (Mobility as a Service) in integrating various forms of transport and transport-related services into a single on-demand mobility service, this paper proposes a car-sharing-based service for the combined mobility of passengers and freight. In doing so, one-way car-sharing and crowd-shipping concepts are integrated in order to serve part of the existing freight demand in a sustainable and cost-efficient way for users, societies, and the environment. An optimization model is proposed to optimally plan the activation of one-way car-sharing and crowd-shipping services and to determine the optimal number of vehicles to assign to them. Such decisions are aimed at minimizing the total imbalance by serving passenger and freight demand during different time periods. In doing so, the willingness of users to carry freight in their vehicles is also taken into consideration. The capability of the proposed approach is evaluated through representative numerical examples aimed at showing the impact of the model parameters on the solution.Transport and Plannin
Dynamic Hedging Strategies in Clean and Dirty Cryptocurrency Markets: Analyzing Volatility and Portfolio Optimization with TVP-VAR
No full textThis study investigates connectivity, defined as the degree of interdependence and volatility spillovers among cryptocurrencies, in order to better understand their behavior during periods of financial stress. The methodological framework is based on the Time-Varying Parameter Vector Autoregressive (TVP-VAR) model, which enables a flexible analysis of the evolving dynamic relationships among financial assets over time.The main objective is to assess the role of three categories of cryptocurrencies so-called "dirty" cryptocurrencies (Bitcoin and Ethereum), "clean" cryptocurrencies (Algorand and Cardano), and stablecoins (USDT and USDC) in risk management and their effectiveness as hedging instruments in diversified portfolios, particularly during periods of heightened uncertainty such as the COVID-19 pandemic and the Russia–Ukraine conflict.Using daily data from July 2019 to July 2024, the analysis reveals strong interconnectedness among volatile cryptocurrencies, especially between Bitcoin and Ethereum. In contrast, stablecoins exhibit greater stability and resilience to shocks. These findings highlight the relevance of accounting for dynamic interlinkages between assets when designing portfolios that are resilient to financial crises

Embracing the future of the policy sciences: big data in pedagogy and practice
No full textAlthough the emergence of Big Data provides an opportunity to synthesize and mobilize ever greater amounts of policy-relevant knowledge, it has not received adequate attention in studies of policy pedagogy and practice. In this chapter, we highlight the relevance of Big Data to policy analysis, policy implementation, and policy studies through a discussion of basic machine learning techniques and an illustration of their application in the case of better understanding policy response to COVID-19. Subsequently – based on a bibliometric review of nearly 2,500 publications on big data in public policy and content analysis of course titles and descriptions in 122 programs worldwide – we make an evidence-informed appeal to increase the uptake of big data in policy research as well as teaching. We conclude that appropriate engagement with the big data phenomenon can help the policy sciences remain relevant and move a step closer to integrating policy research, pedagogy, and practice.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Organisation & Governanc
Impact of dividend policy on earnings management and the moderating effect of the board of directors and the audit committees: The French case
No full textResearch Question- To what extent can governance mechanisms (audit committee and board of directors) affect the relationship between dividend policy and earnings management? Motivation- The majority of the literature has showed that dividend policy can influence earnings management. However, the empirical results did not lead to the same results. Our study seeks to fill this gap by examining whether this impact can vary by taking into account certain moderating variables such as: the size of the board of directors, the number of board meetings, the independence and expertise of the members of the audit committees. Idea- This study examines the moderating effect of certain variables related to the effectiveness of the board of directors and the audit committee on the impact of the dividend policy on earnings management. Data- The authors selected French non-financial companies listed on the CAC All Tradable index during the 2008-2015 period. Tools- To test study's hypotheses, the authors applied linear regression with a panel data using the datastream database. Generalized least squares method is used to estimate the models. Findings- The results of this study show that the effect of the dividend policy on earnings management is more favorable in the case of companies where the board of directors is large. Contribution- This study shows that dividend policy constitutes an objective of earnings management especially in the companies with boards made up of a large number of directors. Investors and academics have an interest in better understanding the concepts: dividend policy and earnings management because the debates relating to these two variables have always been the subject of controversy. Thus, they can refer to corporate dividend policy as a mechanism for assessing the authenticity of corporate financial reports
Loan officers and soft information production
No full textAccording to the current paradigm of relationship lending in small business lending, loan officers produce soft information about their small- and medium-sized enterprises borrowers. We examine this common assumption by directly measuring soft information and testing how can loan officer accumulate this type of information. We used a data-set on Tunisian small businesses via a specially designed questionnaire addressed to loan officers and a data based on lines of credit files. We find that on balance loan officers play an important role in producing soft information. In fact, the specificity of loan officer, direct contact with the manager, and regular visit to the firm contribute to more information production, while frequent loan officer turnover hinders this mission. To further pursue the validity of our empirical methodology, we test whether the production of soft information by loan officers benefits borrowers. Our results confirm that besides soft information, audited financial statements improve loan contract terms while public banks are more devoted to relax financing constraints
Does CEO emotional bias affect performance?
No full textThis article is focused on tackling the issue of the impact of the bank CEO's emotional bias on the Tunisian banks' performance level while accounting for the mediating role of the control systems. In this regard, an empirical study has been set up through a questionnaire undertaken as an appropriately fit data collection method administered to a sample of 100 CEOs of Tunisian banks. Actually, the present research is intended to help in reflecting an original approach, since it serves to highlight the behavioral aspects' crucial role in explaining the performance level within the framework of the organizational architecture theory. To the best of our knowledge, this work represents a pioneering study that deals with exploring such a research area within the Tunisian context. Indeed, the achieved results reveal with no doubt that the behavioral dimension constitutes a central aspect in the organizational architecture as it helps greatly in reflecting the intermingling of the incentive aspect with the evaluation system with respect to the accounts manager
