Research Objectives and Focus

The primary objective of this thesis is to organize and simplify the complex academic literature regarding the relationship between corporate disclosure levels and a firm's cost of capital. By analyzing theoretical foundations and evaluating existing empirical methodologies, the study seeks to clarify how information transparency influences investor perceptions and market outcomes, ultimately providing a structured framework for practitioners.

• The theoretical relationship between corporate disclosure and capital costs.
• Methodological challenges and common proxies used in empirical research.
• Comparative analysis of priced risk versus information asymmetry studies.
• The concept of a "good-practice level" of disclosure for business efficiency.
• Future research directions and the necessity of holistic empirical approaches.

Summary of Chapters

1 Introduction: This chapter outlines the thesis by defining the research scope, the rationale for examining the link between disclosure and capital costs, and the academic objectives of the study.

2 Relevance and Components of the Costs of Capital: It defines the cost of capital from various perspectives and introduces the Weighted Average Cost of Capital (WACC) as a dominant metric.

3 Causal Link between Disclosure and Costs of Capital: This section explores the theoretical impact of corporate transparency on reducing information asymmetry, estimation risk, and transaction costs.

4 Methodological Measuring Approaches: It discusses the diverse and often complex proxies used by scholars to empirically quantify disclosure levels and their effects on costs of equity and debt.

5 Empirical Evidence for the Impact of Disclosure on Costs of Capital: This chapter categorizes existing empirical studies and evaluates contradicting results based on methodological drawbacks like self-selection bias.

6 Conclusion: It summarizes the findings, addresses the current state of research, and offers suggestions for future investigations while discussing the gap between academic and practitioner views.

Frequently Asked Questions

What is the core subject of this thesis?

The thesis examines the theoretical and empirical relationship between the level of corporate disclosure provided by a firm and its resulting cost of capital, covering both debt and equity.

What are the primary thematic areas covered?

The work focuses on the components of capital costs, the impact of information asymmetry, the challenges of measuring these intangible variables, and the existing empirical findings in the literature.

What is the primary objective of this research?

The main goal is to structure and simplify the vast and often confusing academic literature into a coherent framework that bridges the gap between theoretical research and practical business application.

Which scientific methodology does the author employ?

The thesis adopts a deductive approach, starting with a theoretical overview of capital cost concepts and moving into a comprehensive literature review that categorizes and evaluates existing empirical studies.

What topics are discussed in the main body?

The main body covers the definitions of disclosure, the theoretical link to risk reduction (estimation and transaction risk), common measurement proxies, and a critical categorization of studies based on their focus (e.g., priced risk vs. information asymmetry).

Which keywords define this work?

The work is defined by terms such as Costs of Capital, Voluntary Disclosure, Estimation Risk, Information Asymmetry, and the "good-practice level" of disclosure.

What is the "good-practice level of disclosure" concept?

It is a findings-based perspective suggesting that firms benefit from disclosing information up to a certain benchmark, beyond which additional disclosures offer only marginal returns to investors.

How does the author view the "self-selection bias" in previous studies?

The author considers it a critical limitation, noting that firms often choose reporting strategies after observing the content of the information, which distorts the perceived impact of disclosure on capital costs.
