Evidence on the Trade-Off between Real Activities Manipulation and Accrual-Based Earnings Management
Evidence on the trade-off between real activities manipulation and accrual-based earningsmanagementAmy Y. ZangThe Hong Kong University of Science and TechnologyAbstract: I study whether managers use real activities manipulation and accrual-based earnings management as substitutes in managing earnings. I find that managers trade off the two earnings management methods based on their relative costs and that managers adjust the level of accrual-based earnings management according to the level of real activities manipulation realized. Using an empirical model that incorporates the costs associated with the two earnings management methods and captures managers’ sequential decisions, I document large sample evidence consistent with managers using real activities manipulation and accrual-based earnings management as substitutes.Keywords:real activities manipulation, accrual-based earnings management, trade-off Data Availability:Data are available from public sources indicated in the text.I am grateful for the guidance from my dissertation committee members, Jennifer Francis (chair), Qi Chen, Dhananjay Nanda, Per Olsson and Han Hong.

I gratefully acknowledge the financial support from the Fuqua School of Business at Duke University, the Deloitte Foundation, University of Rochester and the HKUST. Errors and omissions are my responsibility.I.INTRODUCTIONI study how firms trade off two earnings management strategies, real activities manipulation and accrual-based earnings management, using a large sample of firms over 1987–2008. Prior studies have shown evidence of firms altering real activities to manage earnings (e.g., Roychowdhury 2006; Graham et al. 2005) and evidence that firms make choices between the two earnings management strategies (Cohen et al. 2008; Cohen and Zarowin 2010; Badertscher 2011). My study extends research on the trade-off between real activities manipulation and accrual-based earnings management by documenting a set of variables that explain the costs of both real and accrual earnings management. I provide evidence for the trade-off decision as a function of the relative costs of the two activities and show that there is direct substitution between them after the fiscal year end due to their sequential nature.Real activities manipulation is a purposeful action to alter reported earnings in a particular direction, which is achieved by changing the timing or structuring of an operation, investment or financing transaction, and which has suboptimal business consequences. The idea that firms engage in real activities manipulation is supported by the survey evidence in Graham et al. (2005).1 They report that 80 percent of surveyed CFOs stated that, in order to deliver earnings, they would decrease research and development (R&D), advertising and maintenance expenditures, while 55 percent said they would postpone a new project, both of which are real activities manipulation.1 In particular, Graham et al. (2005) note that: “The opinion of many of the CFOs is that every companywould/should take actions such of these [real activities manipulation] to deliver earnings, as long as the real sacrifices are not too large and as long as the actions are within GAAP.” Graham et al. further conjecture that CFOs’ greater emphasis on real activities manipulation rather than accrual-based earnings management may be due to their reluctance to admit to accounting-based earnings management in the aftermath of the Enron and Worldcom accounting scandals.Unlike real activities manipulation, which alters the execution of a real transaction taking place during the fiscal year, accrual-based earnings management is achieved by changing the accounting methods or estimates used when presenting a given transaction in the financial statements. For example, changing the depreciation method for fixed assets and the estimate for provision for doubtful accounts can bias reported earnings in a particular direction without changing the underlying transactions.The focus of this study is on how managers trade off real activities manipulation and accrual-based earnings management. This question is important for two reasons. First, as mentioned by Fields et al. (2001), examining only one earnings management technique at a time cannot explain the overall effect of earnings management activities. In particular, if managers use real activities manipulation and accrual-based earnings management as substitutes for each other, examining either type of earnings management activities in isolation cannot lead to definitive conclusions. Second, by studying how managers trade off these two strategies, this study sheds light on the economic implications of accounting choices; that is, whether the costs that managers bear for manipulating accruals affect their decisions about real activities manipulation. As such, the question has implications about whether enhancing SEC scrutiny or reducing accounting flexibility in GAAP, for example, might increase the levels of real activities manipulation engaged in by firms.I start by analyzing the implications for managers’ trade-off decisions due to the different costs and timing of the two earnings management strategies. First, because both are costly activities, firms trade off real activities manipulation versus accrual-based earnings management based on their relative costliness. That is, when one activity is relatively more costly, firms engage in more of the other. Because firms face different costs and constraints for the twoearnings management approaches, they show differing abilities to use the two strategies. Second, real activities manipulation must occur during the fiscal year and is realized by the fiscal year end, after which managers still have the chance to adjust the level of accrual-based earnings management. This timing difference implies that managers would adjust the latter based on the outcome of real activities manipulation. Hence, there is also a direct, substitutive relation between the two: if real activities manipulation turns out to be unexpectedly high (low), managers will decrease (increase) the amount of accrual-based earnings management they carry out.Following prior studies, I examine real activities manipulation through overproduction and cutting discretionary expenditures (Roychowdhury 2006; Cohen et al. 2008; Cohen and Zarowin 2010). I test the hypotheses using a sample of firms that are likely to have managed earnings. As suggested by prior research, earnings management is likely to occur when firms just beat/meet an important earnings benchmark (Burgstahler and Dichev 1997; DeGeorge et al. 1999). Using a sample containing more than 6,500 earnings management suspect firm-years over the period 1987–2008, I show the empirical results that real activities manipulation is constrained by firms’ competitive status in the industry, financial health, scrutiny from institutional investors, and the immediate tax consequences of manipulation. The results also show that accrual-based earnings management is constrained by the presence of high-quality auditors; heightened scrutiny of accounting practice after the passage of the Sarbanes-Oxley Act (SOX); and firms’ accounting flexibility, as determined by their accounting choices in prior periods and the length of their operating cycles. I find significant positive relations between the level of real activities manipulation and the costs associated with accrual-based earnings management, and also between the level of accrual-based earnings management and the costs associated with realactivities manipulation, supporting the hypothesis that managers trade off the two approaches according to their relative costliness. There is a significant and negative relation between the level of accrual-based earnings management and the amount of unexpected real activities manipulation, consistent with the hypothesis that managers “fine-tune” accruals after the fiscal year end based on the realized real activities manipulation. Additional Hausman tests show results consistent with the decision of real activities manipulation preceding the decision of accrual-based earnings management.Two recent studies have examined the trade-off between real activities manipulation and accrual-based earnings management. Cohen et al. (2008) document that, after the passage of SOX, the level of accrual-based earnings management declines, while the level of real activities manipulation increases, consistent with firms switching from the former to the latter as a result of the post-SOX heightened scrutiny of accounting practice. Cohen and Zarowin (2010) show that firms engage in both forms of earnings management in the years of a seasoned equity offering (SEO). They show further that the tendency for SEO firms to use real activities manipulation is positively correlated with the costs of accrual-based earnings management in these firms.2 Compared to prior studies, this study contributes to the earnings management literature by providing a more complete picture of how managers trade off real activities manipulation and accrual-based earnings management. First, it documents the trade-off in a more general setting by using a sample of firms that are likely to have managed earnings to beat/meet various earnings targets. The evidence for the trade-off decisions discussed in this study does not depend on a specific period (such as around the passage of SOX, as in Cohen et al. 2008) or a significant corporate event (such as a SEO, as in Cohen and Zarowin 2010).2 Cohen and Zarowin (2010) do not examine how accrual-based earnings management for SEO firms varies based on the costs of real and accrual earnings management.Second, to my knowledge, mine is the first study to identify a set of costs for real activities manipulation and to examine their impact on both real and accrual earnings management activities. Prior studies (Cohen et al. 2008; Cohen and Zarowin 2010) only examine the costs of accrual-based earnings management. By including the costs of real activities manipulation, this study provides evidence for the trade-off as a function of the relative costs of the two approaches. That is, the level of each earnings management activity decreases with its own costs and increases with the costs of the other. In this way, I show that firms prefer different earnings management strategies in a predictive manner, depending on their operational and accounting environment.Third, I consider the sequential nature of the two earnings management strategies. Most prior studies on multiple accounting and/or economic choices implicitly assume that managers decide on multiple choices simultaneously without considering the sequential decision process as an alternative process (Beatty et al. 1995; Hunt et al. 1996; Gaver and Paterson 1999; Barton 2001; Pincus and Rajgopal 2002; Cohen et al. 2008; Cohen and Zarowin 2010). In contrast, my empirical model explicitly considers the implication of the difference in timing between the two earnings management approaches. Because real activities manipulation has to occur during the fiscal year, but accrual manipulation can occur after the fiscal year end, managers can adjust the extent of the latter based on the realized outcomes of the former. I show that, unlike the trade-off during the fiscal year, which is based on the relative costliness of the two strategies, there is a direct substitution between the two approaches at year end when real activities manipulation is realized. Unexpectedly high (low) real activities manipulation realized is directly offset by a lower (higher) amount of accrual earnings management.Section II reviews relevant prior studies. Section III develops the hypotheses. Section IV describes the research design, measurement of real activities manipulation, accrual-based earnings management and independent variables. Section V reports sample selection and empirical results. Section VI concludes and discusses the implications of my results.II.RELATED LITERATUREThe extensive literature on earnings management largely focuses on accrual-based earnings management (reviewed by Schipper 1989; Healy and Wahlen 1999; Fields et al. 2001). A smaller stream of literature investigates the possibility that managers manipulate real transactions to distort earnings. Many such studies examine managerial discretion over R&D expenditures (Baber et al. 1991; Dechow and Sloan 1991; Bushee 1998; Cheng 2004). Other types of real activities manipulation that have been explored include cutting advertising expenditures (Cohen et al. 2010), stock repurchases (Hribar et al. 2006), sales of profitable assets (Herrmann et al. 2003; Bartov 1993), sales price reductions (Jackson and Wilcox 2000), derivative hedging (Barton 2001; Pincus and Rajgopal 2002), debt-equity swaps (Hand 1989), and securitization (Dechow and Shakespeare 2009).The prevalence of real activities manipulation as an earnings management tool was not well understood until recent years. Graham et al. (2005) survey more than 400 executives and document the widespread use of real activities manipulation. Eighty percent of the CFOs in their survey stated that, in order to meet an earnings target, they would decrease expenditure on R&D, advertising and maintenance, while 55 percent said they would postpone a new project, even if such delay caused a small loss in firm value. Consistent with this survey, Roychowdhury (2006) documents large-sample evidence suggesting that managers avoid reporting annual losses ormissing analyst forecasts by manipulating sales, reducing discretionary expenditures, and overproducing inventory to decrease the cost of goods sold, all of which are deviations from otherwise optimal operational decisions, with the intention of biasing earnings upward.Recent research has started to examine the consequence of real activities manipulation. Gunny (2010) finds that firms that just meet earnings benchmarks by engaging in real activities manipulation have better operating performance in the subsequent three years than do firms that do not engage in real activities manipulation and miss or just meet earnings benchmarks. Bhojraj et al. (2009), on the other hand, show that firms that beat analyst forecasts by using real and accrual earnings management have worse operating performance and stock market performancein the subsequent three years than firms that miss analyst forecasts without earnings management.Most previous research on earnings management examines only one earnings management tool in settings where earnings management is likely to occur (e.g., Healy 1985; Dechow and Sloan 1991; Roychowdhury 2006). However, given the portfolio of earnings management strategies, managers probably use multiple techniques at the same time. A few prior studies (Beatty et al. 1995; Hunt et al. 1996; Gaver and Paterson 1999; Barton 2001; Pincus and Rajgopal 2002; Cohen et al. 2008; Cohen and Zarowin 2010; Badertscher 2011) examine how managers use multiple accounting and operating measures to achieve one or more goals.Beatty et al. (1995) study a sample of 148 commercial banks. They identify two accrual accounts (loan loss provisions and loan charge-offs) and three operating transactions (pension settlement transactions, miscellaneous gains and losses due to asset sales, and issuance of new securities) that these banks can adjust to achieve three goals (optimal primary capital, reported earnings and taxable income levels). The authors construct a simultaneous equation system, in which the banks minimize the sum of the deviations from the three goals and from the optimallevels of the five discretionary accounts.3 They find evidence that some, but not all, of the discretionary accounts (including both accounting choices and operating transactions) are adjusted jointly for some of the objectives identified.Barton (2001) and Pincus and Rajgopal (2002) study how firms manage earning volatility using a sample of Fortune 500, and oil and gas, firms respectively. Both studies use simultaneous equation systems, in which derivative hedging and accrual management are simultaneously determined to manage earnings volatility. Barton (2001) suggests that the two activities are used as substitutes, as evidenced by the negative relation between the two after controlling for the desired level of earnings volatility. Pincus and Rajgopal (2002) find similar negative relation, but only in the fourth quarter.There are two limitations in the approach taken by the above studies. First, in the empirical tests, they assume that the costs of adjusting discretionary accounts are constant across all firms and hence do not generate predictions or incorporate empirical proxies for the costs. In other words, they do not consider that discretion in some accounts is more costly to adjust for some firms. Hence, these studies fail to consider the trade-off among different tools due to their relative costs. Second, they assume all decisions are made simultaneously. If some decisions are made before others, this assumption can lead to misspecification in their equation system.Badertscher (2011) examines overvaluation as an incentive for earnings management. He finds that during the sustained period of overvaluation, managers use accrual earnings management in early years, real activities manipulation in later years, and non-GAAP earnings management as a last resort. He claims that the duration of overvaluation is an important determinant in managers’ choice of earnings management approaches, but he does not model the3Hunt et al. (1996) and Gaver and Paterson (1999) follow Beatty et al. (1995) and construct similar simultaneous equation systems.trade-off between real activities manipulation and accrual-based earnings management based on their relative costliness, nor does his study examine the implication of the sequential nature of the two activities during the year.Two recent studies examine the impact of the costs of accrual-based earnings management on the choice of earnings management strategies. Cohen et al. (2008) show that, on average, accrual-based earnings management declines, but real activities manipulation increases, after the passage of SOX. They focus on one cost of accrual-based earnings management, namely the heightened post-SOX scrutiny of accounting practice, and its impact on the levels of real and accrual earnings management. Using a sample of SEO firms, Cohen and Zarowin (2010) examine several costs of accrual-based earnings management and show that they are positively related to the tendency to use real activities manipulation in the year of a SEO. Neither study examines the costs of real activities manipulation or considers the sequential nature of the two strategies. Hence, they do not show the trade-off decision as a function of the relative costs of the two strategies or the direct substitution between the two after the fiscal year end.III.HYPOTHESES DEVELOPMENTConsistent with prior research on multiple earnings management strategies, I predict that managers use real activities manipulation and accrual-based earnings management as substitutes to achieve the desired earnings targets. Unlike prior research, however, I investigate the differences in the costs and timing of real activities manipulation and accrual-based earnings management, and their implications for managers’ trade-off decisions.Both real activities manipulation and accrual-based earnings management are costly activities. Firms are likely to face different levels of constraints for each strategy, which will leadto varying abilities to use them. A manager’s trade-off decision, therefore, depends on the relative costliness of the two earnings management methods, which is in turn determined by the firm’s operational and accounting environment. That is, given the desired level of earnings, when discretion is more constrained for one earnings management tool, the manager will make more use of the other. This expectation can be expressed as the following hypothesis: H1: Other things being equal, the relative degree of accrual-based earnings management vis-à-vis real activities manipulation depends on the relative costs of each action.Accrual-based earnings management is constrained by scrutiny from outsiders and the available accounting flexibility. For example, a manager might find it harder to convince a high-quality auditor of his/her aggressive accounting estimates than a low-quality auditor. A manager might also feel that accrual-based earnings management is more likely to be detected when regulators heighten scrutiny of firms’ accounting practice. Other than scrutiny from outsiders, accrual-based earnings management is constrained by the flexibility within firms’ accounting systems. Firms that are running out of such flexibility due to, for example, their having made aggressive accounting assumptions in the previous periods, face an increasingly high risk of being detected by auditors and violating GAAP with more accrual-based earnings management. Hence, I formulate the following two subsidiary hypotheses to H1:H1a: Other things being equal, firms facing greater scrutiny from auditors and regulators have a higher level of real activities manipulation.H1b: Other things being equal, firms with lower accounting flexibility have a higher level of real activities manipulation.Real activities manipulation, as a departure from optimal operational decisions, is unlikely to increase firms’ long-term value. Some managers might find it particularly costly because theirfirms face intense competition in the industry. Within an industry, firms are likely to face various levels of competition and, therefore, are under different amounts of pressure when deviating from optimal business strategies. Management research (as reviewed by Woo 1983) shows that market leaders enjoy more competitive advantages than do followers, due to their greater cumulative experience, ability to benefit from economies of scale, bargaining power with suppliers and customers, attention from investors, and influence on their competitors. Therefore, managers in market-leader firms may perceive real activities manipulation as less costly because the erosion to their competitive advantage is relatively small. Hence, I predict the following: H1c: Other things being equal, firms without market-leader status have a higher level of accrual-based earnings management.For a firm in poor financial health, the marginal cost of deviating from optimal business strategies is likely to be high. In this case, managers might perceive real activities manipulation as relatively costly because their primary goal is to improve operations. This view is supported by the survey evidence documented by Graham et al. (2005), who find that CFOs admit that if the company is in a “negative tailspin,” managers’ efforts to survive will dominate their reporting concerns. This reasoning leads to the following subsidiary hypothesis to H1: H1d: Other things being equal, firms with poor financial health have a higher level of accrual-based earnings management.Managers might find it difficult to manipulate real activities when their operation is being monitored closely by institutional investors. Prior studies suggest that institutional investors play a monitoring role in reducing real activities manipulation.4 Bushee (1998) finds that, when4 However, there is also evidence that “transient” institutions, or those with high portfolio turnover and highly diversified portfolio holdings, increase managerial myopic behavior (e.g., Porter 1992; Bushee 1998; Bushee 2001). In this study, I focus on the average effect of institutional ownership on firms’ earnings management activities without looking into the investment horizon of different institutions.institutional ownership is high, firms are less likely to cut R&D expenditure to avoid a decline in earnings. Roychowdhury (2006) also finds a negative relation between institutional ownership and real activities manipulation to avoid losses. Unlike accrual-based earnings management, real activities manipulation has real economic consequences for firms’ long-term value. Institutional investors, being more sophisticated and informed than other investors, are likely to have a better understanding of the long-term implication of firms’ operating decisions, leading to more effort to monitor and curtail real activities manipulation than accrual-based earnings management, as predicted in the following subsidiary hypothesis:H1e: Other things being equal, firms with higher institutional ownership have a higher level of accrual-based earnings management.Real activities manipulation is also costly due to tax incentives. It might be subject to a higher level of book-tax conformity than accrual-based earnings management, because the former has a direct cash flow effect in the current period, while the latter does not. Specifically, when firms increase book income by cutting discretionary expenditures or by overproducing inventory, they also increase taxable income and incur higher tax costs in the current period.5 In contrast, management of many accrual accounts increases book income without current-period tax consequences. For example, increasing the estimated useful lives of long-term assets, decreasing write-downs for impaired assets, recognizing unearned revenue aggressively, and decreasing bad debt expense can all increase book income without necessarily increasing current-year taxable income. Therefore, for firms with higher marginal tax rates, the net present value of the tax costs associated with real activities manipulation is likely to be higher than that of accrual-based earnings management, leading to the following prediction:5Other types of real activities manipulation, such as increasing sales by discounts and price cuts, and sale of long-term assets, are also book-tax conforming earnings management.H1f: Other things being equal, firms with higher marginal tax rates have a higher level of accrual-based earnings management.Another difference between the two earnings management strategies that will influence managers’ trade-off decisions is their different timing. H1 predicts that the two earnings management strategies are jointly determined and the trade-off depends on their relative costliness. However, a joint decision does not imply a simultaneous decision. Because real activities manipulation changes the timing and/or structuring of business transactions, such decisions and activities have to take place during the fiscal year. Shortly after the year end, the outcome of the real activities manipulation is revealed, and managers can no longer engage in it. Note that, when a manager alters real business decisions to manage earnings, s/he does not have perfect control over the exact amount of the real activities manipulation attained. For example, a pharmaceutical company cuts current-period R&D expenditure by postponing or cancelling development of a certain drug. This real decision can include a hiring freeze and shutting down the research site. The manager may be able to make a rough estimate of the dollar amount of the impact on R&D expenditure from these decisions, but s/he does not have perfect information about it.6 Therefore, managers face uncertainty when they execute real activities manipulation. After the fiscal year end, the realized amount of the real activities manipulation could be higher or lower than the amount originally anticipated.On the other hand, after the fiscal year end but before the earnings announcement date, managers can still adjust the accruals by changing the accounting estimates or methods. In addition, unlike real activities manipulation, which distorts earnings by executing transactions6 Another example is reducing travelling expenditures by requiring employees to fly economy class instead of allowing them to fly business class. This change could be suboptimal because employees might reduce the number of visit they make to important clients or because employees’ morale might be adversely impacted, leading to greater turnover. The manager cannot know for certain the exact amount of SG&A being cut, as s/he does not know the number of business trips taken by employees during the year.。

2. Modern tax principles
• To create an excellent system of taxation, it is necessary to first establish a set of high standard principles for taxation. Little or no attention has been paid by governing bodies to establish such important principles. The lack of principles of taxation has resulted in the most rediculous systems of taxation in the countries where special interests and politicians had the most to gain from manipulating taxation to their advantage.
• (1) The subjects of every state ought to contribute towards the support of the government, as nearly as possible, in proportion to their respective abilities; that is, in proportion to the revenue which they respectively enjoy under the protection of the state. (2)The tax which each individual is bound to pay ought to be certain, and not arbitrary. The time of payment, the manner of payment, the quantity to be paid, ought all to be clear and plain to the contributor, and to every other person.

ChatGPT的开发者、提供者及使用者都应当遵守这些法规，保护用户的隐私权益。
二、知识产权法规：ChatGPT在生成对话时，可能会依赖于大量的训练数据，包括文本、图像等。
因此，在使用这些数据集时应遵循相关的知识产权法规，确保数据的合法来源和使用方式。
此外，ChatGPT生成的内容应当尊重他人的知识产权，不得侵犯他人的版权、专利权等权益。
例如，美国的《数字千年版权法》（DMCA）规定，在使用他人的版权内容时，需符合公平使用原则，否则可能会引发侵权纠纷。
三、虚假宣传法规：ChatGPT的应用场景涵盖了多个领域，包括广告、销售、市场营销等。
在这些领域中，禁止虚假宣传和不当竞争行为是非常重要的法规。
例如，美国的《虚假广告法》（FTC Act）规定，禁止虚假宣传行为，要求广告商必须提供真实、准确的产品信息，并不得误导消费者。
ChatGPT应用领域中的内容生成也应遵守这些法规，确保生成的内容真实可靠。

Plot the indifference curves on the same figure as the efficient set and then proceed to choose the portfolio that is on the indifference curve that is “further northwest”. This portfolio will correspond to the point where an indifference curve is just tangent to the efficient set.

Selection of the optimal portfolio
Assumptions
Nonsatiation: investors are assumed to prefer higher levels of terminal wealth to lower levels of terminal wealth. Risk Aversion: the investor will choose the portfolio with the smaller standard deviation
二. The Theory of Security Portfolio
Markowitz (1952)
1.The analysis of single security
Expected return and uncertainty (or risk) Expected value (or mean) can be viewed as a measure of the potential reward associated with any portfolio, and standard deviation can be viewed as a measure of the risk.

indifference curves: represents an investor’s preferences for risk and return Features:
All portfolios that lie on a given indifference curve are equally desirable to the investor. An investor will find any portfolio that is lying on an indifference curve that is “further northwest” to be more desirable than any portfolio lying on an indifference curve that is “not as far northwest” An investor has an infinite number of indifference curves.
