Diese Dissertation umfasst drei Studien über die Relevanz von Finanzinformationen für Investitionsentscheidungen. Alle drei Studien sind empirischer Natur und untersuchen Finanzinformationen deutscher Firmen mit verschiedenen Forschungsmethoden. Die erste Studie beschreibt den Umfang und Detailierungsgrad von Finanzinformationen mit Bezug auf ein spezifisches Akquisitionsmerkmal: Earnouts. Sie liefert explorative Einblicke in die Berichterstattung über Earnouts und deren Zielerreichung in dem Zeitraum nach der Akquisition. Die Ergebnisse weisen darauf hin, dass Firmen aussagekräftige Earnout-Informationen veröffentlichen, wenn es sich um wesentliche Akquisitionen für das erwerbende Unternehmen handelt. Die zweite Studie untersucht den separaten Ausweis von außerordentlichen Posten in der Gewinn- und Verlustrechnung von kapitalmarktorientierten sowie nicht-kapitalmarktorientierten Unternehmen. Die Ergebnisse deuten darauf hin, dass kapitalmarktorientierte Unternehmen außerordentliche Posten häufiger aber nicht in unterschiedlicher Höhe ausweisen als nicht-kapitalmarktorientierte Unternehmen. Weiterhin bietet der separate Ausweis von außergewöhnlichen Posten den Nutzern von Finanzinformationen bedeutende Einblicke über deren Relevanz für die zukünftige finanzielle Entwicklung des jeweiligen Unternehmens. Die dritte Studie basiert auf einem Umfrageexperiment mit originalen Finanzinformationen und echten Kleinanlegern. In dieser Studie wird untersucht, wie die Übersetzung(squalität) von Finanzinformationen die Wahrnehmung von Kleinanlegern in Bezug auf Textmerkmale und mögliche Investitionsentscheidungen beeinflusst. Die Ergebnisse zeigen, dass Textmerkmale relevant für die Investitionsentscheidung von Kleinanlegern sind. Weiterhin kann die Übersetzung von Finanzinformationen die Wahrnehmung der Kleinanleger von Textmerkmalen beeinflussen. / This dissertation comprises three essays on the value relevance of financial accounting information for investment decisions. All three essays are of empirical nature and investigate financial accounting information disclosed by German firms via different research methods. The first essay focuses on the extent and level of detail of financial accounting information disclosed by firms with respect to a specific contractual acquisition feature: earnouts. It provides exploratory insights on the reporting on and the performance of earnouts in the period after an acquisition has been executed. Results suggest that firms disclose meaningful information on earnouts when the acquisition is material for the acquiring firm. The second essay examines the reporting of extraordinary items within the income statement for public and private firms. Results indicate that public firms report extraordinary items more frequently but not in different magnitude than private firms. Moreover, a clear separation of ordinary and extraordinary items within the income statement offers additional information to financial statement users with respect to their relevance for the firm’s future performance. The third essay is based on a survey experiment with real firm disclosures and genuine retail investors. It explores how translation (quality) of financial narratives impacts the perception of retail investors in respect to textual characteristics and potential investment decisions. The results suggest that textual characteristics are relevant for retail investors’ investment decisions. Moreover, the translation of financial accounting disclosures can affect an investor’s perception of textual characteristics.

This thesis induces a theory for the pre-measurement phase of the asset recognition process in the financial reporting domain centred upon the use of the induced artefact-based asset recognition criteria which are applicable to all assets. In common with standard-setting bodies, such as the International Accounting Standards Board (IASB), I adopt a social constructionist stance (Miller, 1994). It is one that is constructed from a process of consultation. I consult in order to, first, explore the accounting asset recognition process from a conceptual point of view and, second, so that my social construction in that regard can be legitimised, for the most part, on the basis of a consensus of those consulted. However, unlike the standard setters‘ regulatory process, my analysis is structured using a grounded theory approach. The target audience comprises those experts who have been and/or who are currently involved in some way with the development of the IASB‘s conceptual framework (CF) project, including IASB board members. Different data collection methods were adopted combing both qualitative and quantitative data. In respect of the qualitative research, I carried out two sets of interviews. The first set was conducted with Canadian Accounting Standards Board members in May 2008 and International Accounting Standard Board members in June, 2008. The second set was conducted with more International Accounting Standard Board members, UK-Accounting Standard Baord members and other experts within the area being studied. These two sets of interviews were useful for determining the preliminary concepts and categories in the open coding and axial coding structure. In respect of the quantitative research, the concepts and categories raised from the first two sets of interviews were then used to construct an on line questionnaire. The questionnaires were emailed to national standard setters in Canada, the USA, Australia, Germany and the United Kingdom. This has been followed up with an interview with UK ASB director to help in finalising the theory saturation and to validate the reliability of the generated theory. The generated theory demonstrates a three-circled set of criteria for the pre-measurement phase of an asset recognition process. The three-circled set of asset recognition criteria presented in this thesis breaks free from the narrow definitional and rule based perspective of accounting epistemology to offer an alternative view based on the recognition of artefacts.

This research focused on a formal (theory based) approach to designing Intelligent Tutoring System (ITS) authoring tool involving two specific conventional pedagogical theories—Conversation Theory (CT) and Cognitive Apprenticeship (CA). The research conceptualised an Augmented Conversation and Cognitive Apprenticeship Metamodel (ACCAM) based on apriori theoretical knowledge and assumptions of its underlying theories. ACCAM was implemented in an Intelligent Learning Activity Builder System (ILABS)—an ITS authoring tool. ACCAM’s implementation aims to facilitate formally designed tutoring systems, hence, ILABS―the practical implementation of ACCAM― constructs metamodels for Intelligent Learning Activity Tools (ILATs) in a numerical problem-solving context (focusing on the construction of procedural knowledge in applied numerical disciplines). Also, an Intelligent Learning Activity Management System (ILAMS), although not the focus of this research, was developed as a launchpad for ILATs constructed and to administer learning activities. Hence, ACCAM and ILABS constitute the conceptual and practical contributions that respectively flow from this research. ACCAM’s implementation was tested through the evaluation of ILABS and ILATs within an applied numerical domain―the accounting domain. The evaluation focused on the key constructs of ACCAM―cognitive visibility and conversation, implemented through a tutoring strategy employing Process Monitoring (PM). PM augments conversation within a cognitive apprenticeship framework; it aims to improve the visibility of the cognitive process of a learner and infers intelligence in tutoring systems. PM was implemented via an interface that attempts to bring learner’s thought process to the surface. This approach contrasted with previous studies that adopted standard Artificial Intelligence (AI) based inference techniques. The interface-based PM extends the existing CT and CA work. The strategy (i.e. interface-based PM) makes available a new tutoring approach that aimed fine-grain (or step-wise) feedbacks, unlike the goal-oriented feedbacks of model-tracing. The impact of PM—as a preventive strategy (or intervention) and to aid diagnosis of learners’ cognitive process—was investigated in relation to other constructs from the literature (such as detection of misconception, feedback generation and perceived learning effectiveness). Thus, the conceptualisation and implementation of PM via an interface also contributes to knowledge and practice. The evaluation of the ACCAM-based design approach and investigation of the above mentioned constructs were undertaken through users’ reaction/perception to ILABS and ILAT. This involved, principally, quantitative approach. However, a qualitative approach was also utilised to gain deeper insight. Findings from the evaluation supports the formal (theory based) design approach—the design of ILABS through interaction with ACCAM. Empirical data revealed the presence of conversation and cognitive visibility constructs in ILATs, which were determined through its behaviour during the learning process. This research identified some other theoretical elements (e.g. motivation, reflection, remediation, evaluation, etc.) that possibly play out in a learning process. This clarifies key conceptual variables that should be considered when constructing tutoring systems for applied numerical disciplines (e.g. accounting, engineering). Also, the research revealed that PM enhances the detection of a learner’s misconception and feedback generation. Nevertheless, qualitative data revealed that frequent feedbacks due to the implementation of PM could be obstructive to thought process at advance stage of learning. Thus, PM implementations should also include delayed diagnosis, especially for advance learners who prefer to have it on request. Despite that, current implementation allows users to turn PM off, thereby using alternative learning route. Overall, the research revealed that the implementation of interface-based PM (i.e. conversation and cognitive visibility) improved the visibility of learner’s cognitive process, and this in turn enhanced learning—as perceived.

The concern about how business should behave as one of the dominant institutions in society, widely referred to as corporate social responsibility, has been a subject of interest among academics and practitioners all over the world. The increasing global outlook of business activities and the need to understand environments in most parts of the globe have also made this concept relevant for all time. This thesis therefore relates to a study, which assesses the perceived role of ethics and social responsibility for organisational effectiveness in a developing and African country. It was argued that ethics and social responsibility must first be perceived to be important for business success, before managers’ behaviour can become ethical and reflect greater social responsibility. Using a mainly qualitative approach and aided by some quantitative analysis, the study explored the perceived importance of this construct (ethics and social responsibility) for organisational effectiveness among insurance managers in the Nigerian insurance industry. This exploration and the analysis are based on the theoretical assumptions that personal and situational factors do influence managers’ perception of the importance of ethics and social responsibility and its business assumption. These, therefore, constitute major outcomes of the study. Given that the study is the first of its kind in the insurance industry, and Nigeria, a developing economy, its outcomes further aids our understanding of how managers in an African socio-economic context perceive the construct and their readiness to translate it into business practice. Above all, the thesis demonstrates that the perceived importance of ethics and social responsibility for organisational effectiveness is a function of industry and product nature, individual moral values, corporate ethical values and organisational commitment. The findings suggest that meeting customers’ expectations reinforce trust-relationship, which in turn is moderated by some other personal-situational factors. The findings also indicate that highly idealistic managers were more sympathetic towards the welfare of others, and have higher perception of the important role of ethics and social responsibility for business success.

This research assessed market efficiency, volatility behaviour, asset pricing, and oil price risk exposure of the oil and gas companies quoted on the London Stock Exchange with the aim of providing fresh evidence on the pricing dynamics in this sector. In market efficiency analysis, efficient market hypothesis (EMH) and random walk hypothesis were tested using a mix of statistical tools such as Autocorrelation Function, Ljung-Box Q-Statistics, Runs Test, Variance Ratio Test, and BDS test for independence. To confirm the results from these parametric and non-parametric tools, technical trading and filter rules, and moving average based rules were also employed to assess the possibility of making abnormal profit from the stocks under study. In seasonality analysis, stock returns were tested for the day-of-the-week and month-of-the-year effects. Volatility processes, estimation, and forecasting were undertaken using both asymmetric and symmetric volatility models such as GARCH (1,1) and Threshold ARCH or TARCH (1,1,1) to investigate the volatility behaviour of stock returns. To determine the effect of an exogenous variable on volatility, Brent crude oil price was used in the models formulated as a variance regressor for the assessment of its impact on volatility. The models were then used to forecast the price volatility taking note of the forecasting errors for the determination of the most effective forecasting model. International oil price risk exposure of the oil and gas sector was measured using a multi-factor asset pricing model similar to that developed by Fama and French (1993). Factors used in the asset pricing model are assessed for statistical significance and relevance in the pricing of oil and gas stocks. Data used in the study were mainly the adjusted daily closing prices of oil and gas companies quoted on the exchange. Five indices of FTSE All Share, FTSE 100, FTSE UK Oil and Gas, FTSE UK Oil and Gas Producers, and FTSE AIM SS Oil and Gas were also included in the analysis. Our findings suggest that technical trading rules cannot be used to gain abnormal returns, which could be regarded as a sign for weak form market efficiency. The results from seasonality analysis have not shown any day-of-the-week or monthly effect in stock returns. The pattern of stock returns’ volatility can be estimated and forecasted, although the relationship between risk and return cannot be generalised. On a similar note, the relationship between volatility attributes and the efficient market hypothesis cannot be clearly established. However, we have established that volatility modelling can significantly measure the quantum of risk in the oil and gas sector. Market risk, oil price risk, size and book-to-market related factors in asset pricing models were found to be relevant in the determination of asset prices of the oil and gas companies.

The introduction of the single currency (Euro) in Europe has been referred to as the ‘world’s largest economic experiment’ and has led to major research on the effects of the adoption of a common currency on economic activity with considerable emphasis on its effect on trade flows at the macroeconomic level. However, the investigation of the euro effect on individual sectors has received very little attention and this provides the motivation for the research. The main contribution of this thesis is to the sectoral analysis of the single currency’s effect on bi-lateral trade flows, specifically the effects on the transport equipment manufacturing sector. In order to achieve this, a comparison of the different estimation methods applied in the gravity model literature will be employed to investigate this effect and to identify the factors affecting trade in this sector. This study uses a panel data set which comprises the most recent information on bilateral trade for the EU15 countries from 1990 to 2008. This research aims to build on the results obtained in previous studies by employing a more refined empirical methodology and associated tests. The purpose of the tests is to ensure that the euro’s effect on trade is isolated from the other pro- trade policies of the European integration processes, particularly the introduction of the Single Market. The desirable feature of this approach is that, while other studies limit their attention to a particular issue (zero trade flow, time trend, sectoral analysis, cross-correlation, etc.), very few, if any, apply a selection of techniques. Overall, the results demonstrate that the single currency’s effect on trade in this sector is limited with only the fixed effects formulation with year dummy variables showing a significant positive effect of the euro. An obvious policy implication for countries looking to adopt a single currency is that they should be cautious regarding the potential for growth in intra-bloc trade in a particular sector, although they will benefit from the on-going process of integration.

The objective of this study is to obtain an in-depth understanding of the practical working of property tax administration in Jamaica. It highlights the major enforcement and compliance practices along with how the invisible and underlying interactions of actors in the field shape these practices. It also explores those issues and circumstances along with the existing patterns of interests which have contributed to the continued practice of the central administration of the property tax. The study also emphasizes struggles in the property tax field between the various players: the tax authority, the politicians, the developers, the local authorities, the central government and the taxpayers and how each one uses its capital to maintain or dominate its position within the property tax field. The findings revealed that there were various tensions and struggles among the different players within property tax field in Jamaica. The players in the field used their ‘capitals’ to maintain, dominate and or attempt to make changes to the property tax rules. The findings suggest that some property tax enforcement practices were the means through which these tensions were manifested and resolved or on the other hand, the tax authority attempted to use the current practices as hidden agendas to highlight those tensions in order to stand their ground or obliquely suggest changes or even to demonstrate its tacit support of government policies. The findings also suggest that the non-localization of the property tax may be due to varied political interests, mistrust in the local authorities and also the perception by some players that there’s a lack of capital at the local level to manage the tax. Finally, taxpayers’ used their social, economic and cultural capital to resist enforcement and compliance efforts cheating the government of much needed revenues Property tax although not an important national tax is a critical source of revenue for local communities globally. An increased understanding of the working of the practices is beneficial and has implications for both taxpayers and policymakers. The three research questions posed in my study address and highlight the main property tax enforcement strategies and how the tax authority and policymakers use their capital to shape these practices; the extent to which non-localization of the property tax within the Portmore Municipality is influenced by the political dispositions of the players in the field and thirdly the dimensions of property tax compliance and non-compliance in Jamaica. The questions seek to demonstrate how the combination of the actions and interactions of tax administrators, taxpayers, politicians, developers, government bureaucrats reshape administrative practices in the property tax field which have implications for revenue generation and the provision of services. In keeping with the adoption of an interpretive inductive approach, face-to-face interviews were conducted with tax administrators, policymakers, councillors, mayors, taxpayers, members of civil society, a developer and a tax professional. A theoretical framework is created which combines the major themes and theoretical concepts within three strands of literature: tax administration, fiscal decentralization, and Bourdieu’s theory of practice. The structure provides the explanatory lens through which the findings are presented and interpreted. The study contributes to the tax scholarship through an interpretive methodical approach which gives an additional perspective on property tax administration. It answers the call for well-developed tax research dispelling the notion that tax research is adequately dealt with. This study contributes to the tax literature by demonstrating that taxation isn’t just a technical issue; that the legal framework and administrative framework don’t necessarily coincide with practice; that tax practice is shaped by the actions and interactions of players in the field, making it a social construction; that players use their power to influence property tax practice and that players actions are conditioned by their background. The study also contributes a conceptual framework for property tax practice.

This thesis deals with various issues regarding determinants of US corporate credit spreads. These spreads are estimated as the difference between yields to maturity for corporate bonds and default-free instruments (Treasury bonds) of the same maturity. Corporate credit spreads are considered as measures of default risk. However, the premium required by investors for holding risky rather than risk-free bonds will incorporate a compensation not only for the default risk but also for other factors related to corporate bonds such as market liquidity or tax differential between corporate and Treasury bonds. In this study we firstly examine the relationship between bond ratings and credit spreads given that bond rating changes are expected to carry some informational value for debt investors. The findings indicate that bond ratings generally carry some informational value for corporate bond investors. The Granger causal relationship is more evident for negative watch lists and during periods of uncertainty in financial markets. In line with previous studies, our results suggest that changes in credit spreads are significantly related to interest rate levels, systematic risk factors (Fama and French) factors and equity returns.

The thesis conveys three discrete, yet interconnected, studies embracing issues revolving around the exploration of integrated reporting adoption and embeddedness using an institutional theory lens. Integrated reporting can be described as ‘a holistic and integrated representation of the company’s performance in terms of both its finance and its sustainability’ (King III, 2009, p. 54). The first study explores the mimetic, normative and regulative institutional factors, at both an organisational field (meso) and country (macro) levels, affecting the adoption of integrated reporting. Moreover, it provides a portrayal for the adoption of the new practice among corporations. The study uses a relatively large sample driven from the Global Reporting Initiative (GRI) report list and tests it empirically using panel data from 2002- 2010. The second study develops a measure to capture sustainability embeddedness in corporate reports and uses the measure to explore and describe sustainability embeddedness in the integrated reports. Additionally, indicators on sustainability embeddedness in the de facto GRI guidelines are highlighted in comparison to the measure developed. Finally, the third study explores the determinants of sustainability embeddedness in integrated reports using a decoupling lens. More specifically, the study examines the effects of integrated reporting age (as a proxy for early and late adoption), the level of reporting of GRI sustainability guidelines (GRI application level), report assurance and corporate governance on sustainability embeddedness in integrated reports. The study finds that the application of integrated reporting emerged in 2001 amongst only a few corporations in Europe and South America, and was spread among all continents by 2010. While mimetic and normative factors at a meso level were significantly related to integrated reporting adoption, regulative and normative factors at a macro level were found to be of limited association with integrated reporting adoption. Interestingly, corporate size, a firm characteristic control variable, was found to be negatively associated with IR adoption. Exploring sustainability embeddedness in integrated reports in the second study reveals that on average integrated reporters covered 54.4% of the indicators on sustainability embeddedness on the constructed index. Integrated reporters were found to show that sustainability is embedded in some aspects as stakeholder dialogue, executive members’ commitment to sustainability and developing measures to report on various environmental impacts. Conversely, integrated reporters conducting business as usual and prioritised financial aspects in others aspects as remuneration, promotion and appraisal, employee sustainability engagement and investor dialogue regarding sustainability. The results also show that there are great discrepancies in the levels of sustainability embeddedness coverage between integrated reporters. Sustainability embeddedness scores were found to decline, especially in the most recent years of adoption. Regression results in the third study did not find evidence that early adopters of integrated reporting had significantly higher sustainability embeddedness than later adopters. Additionally, corporate governance mechanisms were also unable to explain sustainability embeddedness scores, with the exception of the positive association between corporate two-tier boards and sustainability embeddedness. Embedding sustainability was found to be mainly associated with GRI application level. There was limited evidence to suggest that integrated reporters providing assurance for their reports had higher sustainability embeddedness scores. The studies, taken together, contribute to the body of literature on CSR adoption in general and the adoption of integrated reporting and its practices in particular. The studies also provide contribution and implications by testing institutional theory in a new context.
