Nowadays, there are few issues in finance research which have not been modeled by applying game theoretic concepts, and therefore it is crucial to be familiar with the basics of game theory and its application in finance.
The objective of this paper is to provide an intuitive approach to game theory in finance by first giving an overview of the basic foundations of game theory, and then providing a survey of some selected applications most relevant to the financial practitioner.

Summary of Chapters
1 Introduction: This chapter contextualizes the shift from classical to game-theoretic financial models and outlines the paper's scope regarding corporate finance applications.
2 Game Theoretic Foundations: This section defines core game-theoretic concepts such as Nash equilibrium, dominant strategies, and asymmetric information, which are essential for understanding subsequent financial modeling.
3 Game Theory in the Context of Finance: This chapter evaluates the evolution of financial research, moving from early signaling models to more rigorous, explicitly game-theoretic frameworks that address subgame perfection.
4 Selected Applications of Game Theory in Finance: This part surveys practical applications, focusing specifically on how firms use dividends and capital structure choices as strategic signals under information asymmetry.
5 Critique & Concluding Remarks: The concluding chapter critically assesses the limitations of the rationality assumption while highlighting how newer methods like artificial agent-based analysis provide promising avenues for further research.

Frequently Asked Questions
What is the core focus of this paper?
The paper examines how game theory provides a formal, rigorous language to analyze strategic interactions and information asymmetries within corporate finance.
What are the primary thematic areas covered?
The paper focuses on the transition from classical financial theory to game-theoretic modeling, emphasizing dividend policy, capital structure decisions, and agency conflicts.
What is the main objective of the research?
The aim is to provide an intuitive approach to game theory for finance practitioners, demonstrating how these tools enhance the understanding of real-world corporate behavior.
Which scientific methods are utilized?
The author reviews existing literature, comparing non-game-theoretic signaling models with more modern, explicitly game-theoretic approaches that utilize extensive-form game structures.
What does the main body discuss?
The main body details foundational game theory definitions, the shortcomings of early signaling literature in finance, and detailed applications of these theories to dividends and debt financing.
Which keywords characterize this work?
Key terms include Game Theory, Asymmetric Information, Signaling, Capital Structure, Dividend Policy, and Agency Theory.
How does game theory improve upon the original Modigliani & Miller models?
Game theory allows for the incorporation of realistic elements like asymmetric information, providing a language that ensures logical consistency and empirical testability which early, simpler models lacked.
What is the "dividend puzzle" as addressed in the paper?
The dividend puzzle refers to the observation that firms pay significant dividends despite tax disadvantages; the paper explains how signaling models interpret these payments as credible signals of a firm's future profitability.
