Corporate Governance and Firm Performance: Results from Greek Firms

In this paper, we construct a Governance Index for a sample of Greek companies quoted on the Athens Stock Exchange. We then classify firms, using each firm governance index, into three governance portfolios. Furthermore, the Fama and French model, extended to include a momentum variable, is tested for each of the three governance portfolios. Our findings suggest that most of the firms in our sample are semi-democracies followed by democracies and dictatorships respectively. Good governance appears to be of value in as much as we found higher Tobin’s q ratios for democracies followed by semi-democracies and dictatorships. We, also, report significant negative abnormal returns for shareholder-friendly and manager-friendly firms. The findings of significant negative abnormal returns are consistent with inefficient capital markets. At a practitioner level, the results imply that firms should practice vigorously good governance, as it is a policy of value to shareholders and possibly to other stakeholders.Corporate Governance, Firm Performance, Democratic and Dictatorship Firms

What International Accounting Standards (IAS) bring about to the financial statements of Greek Listed Companies? The case of the Athens Stock Exchange

The aim of the present study is to investigate the repercussions of the accounting changeover from the Greek Accounting Standards (GAS) to the International Accounting Standards (IAS) in relation to the published financial statements of Greek listed companies for the year 2004. The results show that tangible assets, fixed assets, and total liabilities record significantly higher prices under the IAS. Furthermore, it was recorded that, in opposition to the net income after taxes, the book value appears to play a more significant role under the IAS, compared to that under the GAS. There is also evidence that the adjustments of GAS to net income improve incremental value relevance, while the adjustments of GAS to book value do not improve it.International Accounting Standards (IAS), Greek Accounting Standards (GAS), Value relevance, Incremental value relevance, Accounting Standards, Fair value

Corporate governance and its effect on firm value and stock returns of listed companies on the Athens stock exchange

Recent researches have worked on the relationship between Corporate Governance and expected rates on return as well as historical returns. Firstly, we construct an Index of Corporate Governance (CGQL) that measures the quality implementation of Corporate Governance of the enlisted firms on the Athens Stock Exchange distinguishing the firms into Democracies and Dictatorships. An investment strategy that buys Democracies and shorts Dictatorships earns abnormal returns of around 18% annually during the sample period. In this paper we investigate if Corporate Governance matters in investors’ decisions. We try to observe if Corporate Governance is a proxy for firm valuation, a factor of creating and altering abnormal returns, or a risk factor, which can be a “substitute” for market risk (beta), using uni- and multi-variate analyses. The conclusions call into question the utility of Corporate Governance upon firm attractiveness.peer-reviewe

ESGs and customer choice : some empirical evidence

The goal of this paper is to determine whether a company’s performance on environmental, social, and governance (ESG) indicators influences customer choice, and if so, which ones are the most important, as well as whether the COVID-19 pandemic had an effect on changing this hierarchy. Additionally, it intends to investigate the influence of regional and demographic factors on its formation. To achieve this goal, primary data were gathered in Greece via a questionnaire survey. According to the findings, a company’s performance on ESGs influences consumer choice, with an emphasis on environmental and social indicators. It was also demonstrated that a company’s social indicator performance is relevant to both urban and suburban customers. Customers in urban areas place a higher value on a company’s performance in governance indicators than those in suburban areas, who place a higher value on a company’s performance in environmental indicators. Finally, no significant COVID-19 effect was evidenced on the findings, although the emphasis on “social indicators” was further reinforced, probably due to the increase in social awareness of citizens during the pandemic

A Stochastically Optimized Two-Echelon Supply Chain Model: An Entropy Approach for Operational Risk Assessment

Minimizing a company’s operational risk by optimizing the performance of the manufacturing and distribution supply chain is a complex task that involves multiple elements, each with their own supply line constraints. Traditional approaches to optimization often assume determinism as the underlying principle. However, this paper, adopting an entropy approach, emphasizes the significance of subjective and objective uncertainty in achieving optimized decisions by incorporating stochastic fluctuations into the supply chain structure. Stochasticity, representing randomness, quantifies the level of uncertainty or risk involved. In this study, we focus on a processing production plant as a model for a chain of operations and supply chain actions. We consider the stochastically varying production and transportation costs from the site to the plant, as well as from the plant to the customer base. Through stochastic optimization, we demonstrate that the plant producer can benefit from improved financial outcomes by setting higher sale prices while simultaneously lowering optimized production costs. This can be accomplished by selectively choosing producers whose production cost probability density function follows a Pareto distribution. Notably, a lower Pareto exponent yields better supply chain cost optimization predictions. Alternatively, a Gaussian stochastic fluctuation may be proposed as a more suitable choice when trading off optimization and simplicity. Although this may result in slightly less optimal performance, it offers advantages in terms of ease of implementation and computational efficiency
