Research Objective

To examine the sensitivity and validity of the debt signaling hypothesis by applying Extreme Bound Analysis (EBA) to understand the relationship between debt versus equity in emerging and transitional economies, specifically focusing on companies listed in the Pakistan Stock Exchange.

Methodology

The study utilized financial data from non-financial sector companies listed on the Pakistan Stock Exchange for the period 2012-2022. Interest rate data was sourced from the International Monetary Fund's International Financial Statistics. Market values were obtained from the Business Recorder website. The methodology involved applying regression analysis and Extreme Bound Analysis (EBA), a Bayesian solution to sensitivity analysis, to assess the robustness and fragility of the coefficients of various determinants of debt versus equity.

Discussion

The study posits that the signaling hypothesis of capital structure is a valid and sensitive measurement tool. It discusses how various capital structure theories, including Trade-off Theory and Pecking Order Theory, are supported by the findings. The research highlights that financial signaling and information asymmetry are critical issues, and the use of EBA is crucial for obtaining reliable estimates and avoiding biased results. The findings suggest that good corporate governance practices are essential to mitigate information asymmetries and enhance stakeholder reliability.

Key Findings

The analysis revealed that Agency Cost (AC), Liquidity (CR), Investment Growth Opportunity (IGO), Financial Flexibility (FF), Free Cash Flows (FCF), Relative Tax Effect (RTE), and Interest Rate (IR) reflect the robustness and sensitivity of Debt vs. Equity. Specifically, Agency Cost, Liquidity, Financial Flexibility, Investment Growth Opportunity, Free Cash Flows, Relative Tax Effect, and Interest Rate were identified as robust determinants.

Conclusion

The signaling hypothesis of capital structure is a valid and sensitive tool for measurement. The study concludes that factors such as asset tangibility, timing effect, agency cost, profitability, and relative tax may not be costless due to signaling significance. Financial signaling and information asymmetry are critical issues, and the Pecking Order Theory is relevant for companies listed on the Pakistan Stock Exchange. Effective corporate governance and business strategies are crucial for optimal capital structure management and maximizing firm wealth.
