PurposeThe purpose of this paper is to investigate whether revenue-expense matching is inversely associated with cost of capital and information asymmetry, respectively, in the equity markets.Design/methodology/approachThis paper uses a firm-specific measure of revenue-expense matching consistent with Dichev and Tang (2008). To obtain a proxy for cost of equity, this paper uses the average ex ante implied cost of capital estimate calculated from analysts’ forecast data, which are based on the Feltham–Ohlson residual income valuation framework. In additional tests, this paper uses the probability of informed trades (PIN) as a proxy for information asymmetry among equity investors. This paper employs both OLS and fractional logit regression models to test main predictions.FindingsThis paper documents that firms with high revenue-expense matching enjoy a lower cost of capital, supporting the direct impact of high matching on cost of capital by increasing the precision of public information signals. Further, matching of contemporaneous revenues and expenses is inversely associated with information asymmetry, suggesting that the indirect impact of high matching on cost of capital through its impact on information asymmetry is also plausible.Originality/valueAlthough an extensive body of literature has established a link between various disclosure/earnings properties and cost of capital, this research is the first to establish a link between matching and cost of capital. This paper fills the void in the literature by showing that revenue-expense matching – a fundamental property of accounting earnings – affects equity investors’ required rate of returns.
