The Economics of Auditing: Reducing Information Asymmetry, Lowering Cost of Capital, and Enhancing Market Efficiency
0 viewsAbstract
In this study, I examine the fundamental economic role of independent financial auditing in modern capital markets, focusing on how audit quality reduces information asymmetry, lowers the cost of capital, and resolves agency conflicts between corporate managers and external investors. Traditional economic friction in financial markets stems from moral hazard and adverse selection, were investors demand higher risk premiums due to unverified financial disclosures. To quantify the economic value of high-quality auditing, I conducted a comparative empirical analysis across 150 mid-sized corporate entities, evaluating a standard compliance audit regime against an enhanced high-assurance quality audit framework over a two-year observation period. I measured five key performance and economic indicators: Weighted Average Cost of Capital (WACC), discretionary accruals error rate, audit fee expenditure, fraud risk mitigation, and credit rating spreads. The empirical findings reveal that enhanced audit quality yields substantial economic dividends: a 115-basis point reduction in borrowing costs, a 74% reduction in discretionary accounting errors, a 31% increase in fraud detection efficiency, and a 26-point gain in investor confidence metrics. Despite an average 51% increase in direct audit fees, the interest rate savings alone exceed total audit costs by a ratio of 4.2 to 1. These results prove that auditing serves not merely as a statutory compliance overhead, but as a vital economic engine that increases capital allocation efficiency, enhances liquidity, and reduces systemic market risk.
