The effect of board composition on the informativeness and quality of annual earnings: Empirical evidence from Greece

This study examines how the informational quality of annual accounting earnings, varies according to the size and composition of the board of directors of publicly listed firms within the Greek capital market. Data analysis over a period of five years (2000-2004) revealed that the informativeness of annual accounting earnings is positively related to the fraction of outside directors serving on the board, but it is not related to board size. Additionally, firms with a higher proportion of outside board members proved to be more conservative when reporting bad news but on the contrary they do not display greater timeliness on the recognition of good news. Finally, firms with a higher proportion of outside directors report earnings of higher quality compared to firms with a low proportion of outside directors. Our results are robust to several sensitivity tests controlling for endogeneity, firm's fixed effects and alternative models for the estimation of discretionary accruals.     

R &D investments and profitability during the crisis: evidence from Greece

Innovation and Research and Development (R&D) investments have been considered in the literature as a significant determinant of corporate development and sustainability. Previous studies have examined the impact of intangibles on financial performance but not extensively within economic environments of intense financial turmoil. The scope of this study is to shed further light on this issue and examine whether R&D investments had an impact on the profitability of Greek firms especially during the sovereign debt crisis. We collected a sample of Greek corporations that have capitalized their R&D investments and paid significant amounts on R&D expenses during the period 2003–2016. Panel regression results indicated that R&D investments and R&D expenses had a negative impact on the profitability of sample firms before the crisis, but during the crisis (2011–2016) firms which managed to sustain or enhance their level of R&D investments achieved to improve their profitability. These findings corroborate our hypotheses that during a period of limited lending and hearse financial turmoil, R&D investments could be a vital tool for sustaining firms' financial performance. The study offers useful implications for managers and regulators, and contributes to the ongoing debate about the impact of R&D investments on corporate performance.     

European common stochastic long-run trends

The paper examines convergence on the European level by using production functions which include capital and labor as factors of production. The methodology is based on principal-components analysis of common trends appropriate for heterogeneous panels. Using data for the 1960–1997 period and alternative specifications, it is found that convergence can be decisively rejected, although the number of common trends is relatively low (about four or five).     

Size and Power of the Error Correction Model Cointegration Test. A Bootstrap Approach

The size and power of the ECM cointegration test are investigated by using the 'bootstrap critical values'. The purpose of this paper is to show the ability of the bootstrap technique to produce critical values which are much more accurate than the asymptotic ones. The properties of the test have been studied, using Monte Carlo methods, for three different data generating processes. As regards the size of the test, we find that the ECM cointegration test together with the bootstrap critical values perform better than the ECM cointegration test based on the asymptotic critical values. While as regards the power of the tests, the results prove to be similar for the different versions.     

An uncertainty-aware AGV assignment algorithm for automated container terminals

This paper studies job assignments for automated guided in container terminal settings under various conditions of uncertainty. An introduction to their operation is provided, along with a flexible dispatching algorithm, suitable for real-time control of AGVs. Using these concepts a new AGV dispatching approach is developed, capable of operating under uncertain conditions within a detailed container terminal model. Several performance indicators are presented, focused on generic features of vehicle operations as well the assessment of uncertainty levels inside the terminal. From the results of the simulation experiments, it is found that the proposed technique outperforms well known heuristics and alternative algorithms.     

The relevance of earnings and cash flows in a heavily regulated industry: Evidence from the Greek banking sector

This study examines the informational quality of annual accounting earnings within Greek banking institutions taking into consideration the most significant risks facing by such firms and specifically interest rate risk, credit risk, liquidity risk and solvency risk, alongside with the persistence of earnings and bank size as significant determinants of ERCs. Data analysis over a period of ten years (1995-2004) revealed that earnings have higher incremental importance in explaining stock return movements compared to cash flows since earnings change has been found to affect stock returns positively. Additionally, interest rate risk has a positive but not significant impact on the return-earnings relation but on the contrary solvency risk, credit risk and liquidity risk proved to have a negative impact on the valuation process for both small and big-sized banks. Finally, tests on the incremental informativeness of cash flows when earnings are transitory provide significant results suggesting that investors seek for alternative measures of banks' performance when earnings are characterized by increased extremity but inversely cash flows and earnings seem to be equally value relevant when investors evaluate big-sized banking institutions. The results are generally robust to the specification of the empirical models and the research design employed in our study.     

Productivity Trends and the Sterling Real Exchange Rates*

This paper provides favorable econometric evidence for a productivity‐based model of the pound/euro real exchange rate. We find that a 1% increase in UK productivity is consistent with a 3.5% real depreciation of sterling. Likewise, a 1% increase in euro area productivity is compatible with a 5.16% real appreciation of sterling. The asymmetric response of UK and foreign productivity shocks corresponds well with our model if UK labor supply is more elastic than euro area labor supply. Estimates of equilibrium exchange rates suggest that sterling was not overvalued at its 2004Q3 level vis‐à‐vis the euro.     

CORPORATE DIVIDEND POLICY DETERMINANTS: INTELLIGENT VERSUS A TRADITIONAL APPROACH

Dividend is the return that an investor receives when purchasing a company's shares. The decision to pay these dividends to shareholders concerns several other groups of people, such as financial managers, consulting firms, individual and institutional investors, government and monitoring authorities, and creditors, just to name a few. The prediction and modelling of this decision has received a significant amount of attention in the corporate finance literature. However, the methods used to study the aforementioned question are limited to the logistic regression method without any implementation of the advanced and expert methods of data mining. These methods have proven their superiority in other business‐related fields, such as marketing, production, accounting and auditing. In finance, bankruptcy prediction has the vast majority among data‐mining implementations, but to the best of the authors’ knowledge such an implementation does not exist in dividend payment prediction. This paper satisfies this gap in the literature and provides answers that help to understand the so‐called ‘dividend puzzle’. Specifically, this paper provides evidence supporting the hypothesis that data‐mining methods perform better in accuracy measures against the traditional methods used. The prediction of dividend policy determinants provides valuable benefits to all related parties, as they can manage, invest, consult and monitor the dividend policy in a more effective way.

New development: Public service enterprises and consumer-centric management

This article presents consumer satisfaction surveys for three very different public enterprises in the city of Edessa in Greece: the local water and sewerage company, the municipal conservatory of music and a café/restaurant. The majority of consumers were satisfied with the services provided to them by these three public enterprises. Relationships with consumers were managed very differently by the enterprises suggesting that service delivery should be based on the individual characteristics of the enterprise and the environment it operates in.     

Toward rigor and parsimony: a primary validation of Kolvereid’s (1996) entrepreneurial attitudes scales

Questioning the validity of scholarly work is not a typical path to publication in the management field. However, although considerable scholarship assesses entrepreneurial attitudes and intentions models of behaviour, methodological weaknesses in scale development have hampered scholars’ ability to rigorously interpret and build upon their research findings. We review 20 years of research and discover that the pioneer measure of entrepreneurial attitudes as a predictor of self-employment intentions, has yet to be empirically validated. We show that construct and measurement differences, one-off modifications to existing scales and a lack of adequate justification may partially explain why studies in the entrepreneurship education domain have produced inconsistent results. We address this limitation by performing factor analytic techniques on data from two sets of English-speaking university students from two North American countries. The result is a more parsimonious and streamlined ‘mini-Kolvereid’ scale. We further demonstrate that this scale is an effective predictor of entrepreneurial intentions.
