John L. Campbell是美國(guó)佐治亞大學(xué)特里商學(xué)院(Terry College of Business at the University of Georgia)會(huì)計(jì)與金融學(xué)教授,以及赫伯特·E·米勒金融會(huì)計(jì)講席教授(Herbert E.

Campbell博士的研究主要處于會(huì)計(jì)與金融的交叉領(lǐng)域。他的論文探討了會(huì)計(jì)與稅務(wù)信息對(duì)資本市場(chǎng)的影響,研究成果通常具有金融市場(chǎng)監(jiān)管方面的啟示。他的研究發(fā)表在頂尖的會(huì)計(jì)和金融學(xué)期刊上,包括The Accounting Review、Journal of Accounting and Economics、Review of Financial Studies、Review of Accounting Studies、Contemporary Accounting Research、Journal of Financial and Quantitative Analysis。John L.

內(nèi)容提要:
We examine how the informativeness of mandatory risk factor disclosures has evolved over time. While prior research suggests these disclosures became less informative after the 2008 financial crisis due to increased length, boilerplate language, and persistence, we argue that increased standardization reflects disclosure maturity, not reduced informativeness. Empirically, we find that the associations between risk disclosures and firms’ future Beta, stock return volatility, and return comovement have strengthened, supporting the view that risk factor disclosures are increasingly effective at capturing underlying economic risks, thereby validating the SEC's continued mandate.
我們探討了強(qiáng)制性風(fēng)險(xiǎn)因素披露的信息含量隨時(shí)間的變化趨勢(shì)。已有觀點(diǎn)認(rèn)為,2008年金融危機(jī)后,此類披露因模板化、長(zhǎng)度增加而信息含量下降。我們則認(rèn)為,隨著制度成熟,披露內(nèi)容趨于精細(xì)調(diào)整與穩(wěn)定性增強(qiáng),仍能有效反映企業(yè)潛在風(fēng)險(xiǎn)。實(shí)證結(jié)果顯示,風(fēng)險(xiǎn)披露與企業(yè)未來(lái)Beta值、股票收益波動(dòng)性及企業(yè)間收益聯(lián)動(dòng)性的關(guān)聯(lián)性隨時(shí)間顯著增強(qiáng),支持了風(fēng)險(xiǎn)因素披露日益有效的觀點(diǎn),也為SEC繼續(xù)要求企業(yè)披露風(fēng)險(xiǎn)因素提供了進(jìn)一步依據(jù)。
