This study investigates whether tax subsidy is associated with the information effect of future earnings (Future Earnings Response Coefficient, hereafter 'FERC'). Prior studies related with tax subsidy suggest that high- tax subsidy is associated with high-Conservatism. And high-tax subsidy is associated with low-information asymmetry. The hypothesis is tested by using sample firms listed on the Korean Stock Exchange from the year of 2002 to the year of 2009 inclusively. We followed methodology of Tucker and Zarowin (2006). We find that the regression coefficient for tax $subsidy{\times}X_{t3}$ shows a significant positive sign. Also, we performed additional test after controlling for variables related with FERC. The regression coefficient for tax $subsidy{\times}X_{t3}$ is consistent with main results. This result means that the changes in the current stock price of higher-tax subsidy contain more information about their future earnings than the changes in the stock price of lower-abnormal audit hours. The evidence suggests that investors positively understand high-tax subsidy.

This paper examines the effect of the analysts' earnings forecast revisions on stock price after the dividend announcement of the firms has been released. We show that the analysts' upward revisions on earnings forecasts are followed by the positive cumulative abnormal return. We also investigate the signalling effect and the confirmation effect with respect to the effect of the dividend announcement and the earnings forecast revisions on stock price. The test results show that the confirmation effect is stronger than the signalling effect. That is, the investors react only when the analysts' forecasts coincide with the preceding dividend announcement.

This study analyzed how management earnings forecasts would have an effect on future earnings quality. The analysis period of study was from 2003 till 2009 (ofrom 2004 till 2011) based on variables of interest (dependent variables) and the annual data from a total of 475 companies that publicly announced manager's operating earnings forecasts among securities listing companies were used for analysis. As a result, first, it appeared that the more optimistic the manager's earnings forecasts were for the current term, the lower the future earnings quality was. Second, it was found that the lower the accuracy of the manager's earnings forecasts was for the current term, the lower the future earnings quality was. Such findings suggest that management earnings forecasts will be used for determining future earnings quality.

The informativeness of accounting earnings to investors may be used as a measure of the quality of accounting information. The ownership structure is considered to be related to both of two variables, the reliability of earnings reflecting the economic performance of the enterprise and the existence of alternative information sources. Earnings manipulation may mitigate the correlation between accounting earnings and the economic performance and alternative information sources decrease the value of accounting earnings as an information. Thus ownership structure could influence the informativeness of accounting earnings. This paper classifies ownership into three categories, management or inside ownership, institutional investors and large outside blockholders, and diffuse outside ownership and examines theoretically the difference of information effectiveness under each ownership structure. The earnings manipulation hypothesis supports the assertion that the separation of ownership from control motivates earnings manipulation. And differential information hypothesis suggests that more non-accounting information of firms with institutional or concentrated outside ownership is provided. Outside blockholders have alternative information sources that make accounting manipulation ineffective. While most previous studies have examined the effect of ownership on the informativeness of earnings from earnings manipulation hypothesis, this study is motivated by both earnings manipulation hypothesis and differential information hypothesis.

This study first examines whether the matching principle reduces information asymmetry and verifies the effect on earnings sustainability and information asymmetry. In the presence of information asymmetry between managers and information users, managers can reduce information asymmetry by increasing the quality of earnings. Information asymmetry is measured by the financial analysts' earnings forecast variance. When we look at the results of previous studies, verify whether information asymmetry decreases as the response to the revenue cost increases and whether negative relationship between profit persistence and information asymmetry appears when the response to the revenue cost is high. As a result, firms with high revenue cost response showed a decrease in information asymmetry. The persistence of the earningss from the high earnings-cost response shows that the analysts' earnings forecast dispersion decreases. This means that the better the response to the revenue cost, the better the quality of the earnings and the less the information risk about the uncertainty of the enterprise. This study is different from the previous studies in that it analyzed whether the persistence of the earnings that responded to the high revenue cost reduces the information asymmetry. The results of this study suggest that managers can reduce the information asymmetry by carrying out appropriate revenue - cost responses, which provides important implications for stakeholders who use accounting earnings information.

기업의 부실화과정에서 경영자는 그 누구보다도 먼저 부실화의 재무적 징후를 포착할 수 있을 것이며, 부정적인 정보가 외부에 누출되는 경우 발생할 수 있는 은행의 대출중단 등의 치명적 비용을 피하기 위하여 긍정적인 정보를 조작 유포시킬 강한 유인이 존재한다. 이러한 인식에 근거하여 경영자의 이익조절 가능성이 높아지는 기업부실화의 일정시점에서 기업부실예측의 현실적인 모형을 추정하는 데 본 연구의 목적이 있다. 본 연구에서는 부실기업에서 재무정보의 이익조절행위 가능성을 검증하기 위하여 1995년에서 1998년까지 부실화된 115개 상장기업들의 부실전 재무정보를 분석하였고, 총 20개의 재무변수와 그 변화율을 고려하여 부실예측모형을 추정하였다. 이러한 본 연구의 결과는 다음과 같이 요약할 수 있다. 첫째, 부실표본기업의 경우에 재무정보 상호간의 논리성이 와해되거나 크게 약화되어 경영자의 심각한 이익조절행위가 있는 것으로 추정되며, 수익성 정보에 집중되어 부실 2년전부터 심해지고 있는 것으로 나타났다. 둘째, 경영자의 이익조절행위로 인해 논리적 상관관계가 와해되지 않은 재무정보들은 부실예측에 대한 설명력을 갖고 있으며, 본 연구에서 9개의 재무변수로 추정한 부실예측모형은 부실 1년전 80%의 우수한 예측력을 보여주고 있다.

This study investigates the sensitivity reflected in the accounting earnings differs according to the difference in the characteristics of accounting information such as profit and loss for the same market information. For this, market information and accounting data were analyzed for 11,462 non-financial listed companies listed on the KOSPI and KOSDAQ markets from 2012 to 2020 by using Basu's measurement of conditional conservatism and Ball and Shivakumar's measurement of conservatism. Accounting earnings sensitivity was analyzed according to the combination of information. As a result of the study, it was confirmed that both earnings and losses corporates recognize losses with delay, while losses are recognized quickly by loss corporates and delayed recognition by earnings companies. It was confirmed that more strict conservatism was applied to the losses corporates compared to the earnings corporates by delaying the recognition of earnings while the early recognition of the losses. It provides empirical data on the causality between the asymmetric timeliness and the combined effect of market information and accounting information by verifying that the losses corporates responds sensitively to market information while the earnings corporates does not react sensitively to the market information.

증권관리위원회에 신고된 내부자거래는 6개월이내 단기투자에 따른 이익을 회사에 반환하여야 하므로 단기정보를 이용할 가능성이 낮다. 따라서 Fischer(1992)는 상장회사의 임원과 주요주주 등의 주식거래를 증권관리위원회에 신고하도록 하는 제도는 미공개 내부정보를 이용한 내부자거래를 방지하는 효과적 인 방법이라고 주장하고 있다. 본 연구에서는 증권거래소에 신고된 내부자의 거래자료와 상장기업의 기업정보공시자료를 이용하여 내부자의 주식거래가 미공개 내부정보를 이용하고 있는 지를 검토하였다. 1989년부터 1992년까지 4년간 증권거래소에 신고된 상장회사 내부자의 주식거래 중 거래후 1개월내에 기업정보의 공시가 있는 경우를 연구대상으로 한 실증분석결과 이러한 내부자의 주식거래가 일반적으로 미공개된 기업정보를 이용하고 있지 않는 것으로 나타났다. 내부자의 주식 매수 또는 매도후 기업정보 공시시 주가가 상승 또는 하락하는 경우가 각각 약 50%를 차지하고 있으며 내부자의 주식거래후 정보공시 빈도 수도 기대치보다 낮았다. 또한 주식거래에 따른 내부자거래이익은 매도시에는 내부자의 주식거래후 공시된 정보 내용에 따라 결정되며, 정보공시시 주가가 상승하는 비율이 약 50%이고 내부자거래이익이 0보다 작아 매도이후에 주가가 하락할 것이라는 예측은 지지되지 않았다. 내부자거래후 200 거래일까지 누적초과수익률을 분석한 결과에서도 매도시에는 정보이용 가능성이 있지만 매수시에는 내부자거래이익이 작아 정보이용 가능성이 없었다. 또한 내부자종류에 따른 내부자거래이익이 차이가 없어 증권거래소에 신고된 내부자의 주식거래는 곧 공개될 기업정보의 이용과는 관련이 적은 것으로 생각된다.

This study examines the relation between accruals components of earnings and stock return. Earnings are decomposed into four components: discretionary accruals, nondiscretionary accruals, nondiscretionary income and cash flow from operations. Because reported earnings in financial statement consist of cash flow from operations plus total accruals. We decompose total accruals into a discretionary accruals and a nondiscretionary accruals separately, This paper examines the incremental informational content of discretionary accruals and nondiscretionary accruals components of net income by regressing return on earnings'components in multivariate models. The empirical analysis is conducted on a sample of 1,580 firm-years comprising 158 firms during 1984-1995. Discretionary accruals are obtained by decomposing total accruals into discretionary and nondiscretionary accruals components, using a pooled variation of the Jones model(1991). These findings suggest that the discretionary accruals(measured using a variation the Jones model) is priced by the stock market. Specifically, the discretionary accruals and cash flow from operations are positively associated with the stock return, and also nondiscretionary income, discretionary accruals are positively associated with the stock return. While this result is consistent with the market prices the discretionary accruals because it captures value-relevant information. Additional test report evidence consistent with nondiscretionary accruals conveying information about the stock return.
