Real Earnings Management around Stock Repurchases
Abstract:
This study examines whether firms engage in income-decreasing real earnings management around stock repurchases that are made for non-signaling purposes. We focus our investigation on two methods of real earnings management: under-producing inventory and increasing discretionary expenditures. Our results suggest that firms engage in both of these activities prior to repurchasing their shares. This is consistent with firms attempting to mislead investors into under-valuing their stock, allowing them to repurchase their shares at a lower price. Additional analysis suggests that the income-decreasing real earnings management activities are concentrated in the subset of firms that are in strong financial health. Further evidence is provided by examining sets of firms that likely make repurchases for non-signally reasons. The evidence suggests that firms participate in more income-decreasing real earnings management when they have significant amounts of stock options outstanding, and to a lesser extent, when they are overvalued. Finally, we provide evidence that the firms that reduce income-increasing real earnings management experience positive abnormal returns during the period subsequent to the repurchase. We conclude that managers of firms that engage in stock repurchases for non- signaling purposes have incentives to depress their stock price prior to making the repurchase. Our results are important to investors and academics who are interested in the motivations of real earnings management.

Real Earnings Management around Stock Repurchases
1. Introduction
This study examines whether firms engage in income-decreasing real earnings management around stock repurchases that are made for non-signaling purposes. Firms have the incentive to lower their share price prior to making a repurchase in order to reduce the price that they must pay to buy back shares. One way in which firms can accomplish this task is by managing their earnings downward in the period preceding the repurchase. 1 If investors are unaware that a firm’s reported income has been manipulated, then they will undervalue its stock.2 Consistent with this claim, the prior literature has found that firms engage in income- decreasing accruals-based earnings management in the period preceding stock repurchases
(Gong, Louis, and Sun 2008). However, given that real earnings management is more costly to firms than accruals-based earnings management in terms of its effects on future cash flows
(Cohen and Zarowin 2010; Gunny 2010) and that the prevalence of real earnings management
(accruals-based earnings management) has increased (decreased) since the passage of the
Sarbanes-Oxley Act of 2002 (SOX) (Cohen, Dey and Lys 2008), it is important to examine
1 Prior research documents the relation between unexpected earnings and unexpected returns is asymmetric. Specifically, investors penalize firms that miss earnings forecasts more so than they award firms that beat earnings forecasts (Skinner and Sloan 2002). As such, it is reasonable to assume a negative association between earnings decreases and stock returns. In this study, we use the term income-decreasing and a reduction in income-increasing activities synonymously. 2 Previous studies examining the use of income-increasing accruals-based earnings management around equity offerings find that these firms have lower subsequent stock returns compared to other firms (Teoh, Welch, and Wong 199a; Rangan 1998; Teoh, Welch, and Wong 1998b). The authors propose that this result is due to investors’ inability to fully understand that pre-issuance earnings have been managed upward. As a result, they overvalue issuing firms and are subsequently disappointed. In addition, Gong, Louis, and Sun (2008) find that firms using income-decreasing accruals-based earnings management prior to open-market stock repurchases have positive subsequent abnormal stock returns, suggesting that investors are surprised by the improvement in performance after the repurchase occurs. 2 whether firms engage in forms of real earnings management around non-signaling stock repurchases.
This study focuses on two specific types of income-decreasing real earnings management.3 The first method is under-producing inventory. By producing fewer inventories than are necessary to meet expected demand, fixed cost per unit increases, resulting in a higher cost of goods sold, and consequently, lower reported income. The second method considered is increased discretionary spending on research and development (R&D), advertising, and selling, general, and administrative (SG&A) expenses. Since these types of expenditures are generally expensed during the period in which they are incurred, increased spending leads to higher reported expenses, and thus, lower earnings. We predict that firms will engage in both of these real earnings management activities prior to making a stock repurchase.
We additionally examine cross-sectional differences among firms in order to identify which type of firms engage in more income-decreasing real earnings management preceding repurchases. The first cross-sectional test investigates the impact that financial health has on the association between real earnings management and stock repurchases. Prior research finds that firms in stronger financial health are more motivated to manipulate earnings by using real earnings management (Zang 2012). Consistent with the prior research, we expect that these firms have more resources to rely on and more opportunities to decrease production and increase discretionary spending prior to a stock repurchase. Accordingly, hypothesis two predicts that firms in strong financial health engage in more income-decreasing real earnings management prior to making a stock repurchase.
3 This study focuses on firms that participate in income-decreasing real earnings management given the incentives to do so preceding a stock repurchase. In contrast, the prior research mainly focuses on income-increasing real earnings management used to avoid earnings losses, earnings decreases, missing the analysts’ forecast, etc. (Roychowdhury 2006, Zang 2012, among others). 3
Next we examine two sets of firms that are likely to make stock repurchases for non- signaling reasons: firms that have significant outstanding stock options and firms that have overvalued equity. Kahle (2002) finds that the existence of stock options leads firms to make repurchases in order to have shares available to fund employee stock option plans. Since the repurchase is not primarily being used as a signaling device, we expect that these firms will want to accomplish the repurchase as cheaply as possible. Therefore, we predict that firms with greater stock option intensity will be more motivated to depress their stock price prior to making a stock repurchase, and accordingly, will participate in more downward real earnings management.
Finally, we examine the real earnings management behavior of firms that are overvalued.
A firm with overvalued equity has a high stock price, relative to its underlying value, and therefore, can achieve a larger reduction in the repurchase price than other firms. In contrast, firms with undervalued equity have little to gain from using real earnings management to lower their stock price because it is already relatively low. In addition, Ikenberry, Lakonishok, and
Vermaelen (1995) and Kahle (2002) find evidence consistent with undervalued firms making repurchasing for signaling purposes. Therefore, we predict that overvalued firms engage in more income-decreasing real earnings management prior to making a stock repurchase.
Real earnings management is empirically measured in a manner consistent with the prior literature (Roychowdhury 2006; Cohen and Zarowin 2010; Zang 2012). However, because we are interested in firms’ use of income-decreasing activities, our intuition runs opposite of previous studies that examine income-increasing activities. Using OLS regression, this study examines the association between under-produced inventory or increased amounts of discretionary spending and subsequent stock repurchases. The sample period investigated spans from 1988 to 2009. Consistent with Zang (2012), the analysis is performed using the Heckman
4
(1979) two-stage procedure in order to correct for possible sample selection bias, given that firms are more likely to manage earnings in order to meet or beat various benchmarks.
This study finds three main results related to the association between real earnings management and stock repurchases. First, the results suggest that firms, on average, engage in income-decreasing real earnings management around stock repurchases. Specifically, firms produce fewer inventories and increase their discretionary spending in the period preceding the repurchase of their shares. Second, the use of both real earnings management methods is concentrated in the subset of firms that are in strong financial health. This suggests that only the set of firms that can afford to produce fewer inventories and spend more on discretionary expenditures are able to take advantage of the opportunity to manage earnings downward prior to a stock repurchase. Third, we find evidence suggesting that firms with greater stock option intensity, compared to firms with less stock option intensity, participate in more downward earnings management prior to a stock repurchase. We also find marginal evidence that firms with overvalued equity use more income-decreasing real earnings management prior to making a stock repurchase. We conclude that managers of firms that engage in stock repurchases for non- signaling purposes have incentives to depress their stock price prior to making the repurchase.
In additional analysis, we confirm our findings using quarterly data and find qualitatively similar results. Given that the stock price declines prior to the stock repurchase, we expect that those firms that depress their stock price the most will have the greatest amount of positive returns in the period subsequent to the repurchase. Accordingly, we examine firms’ abnormal returns in the period following the stock repurchase and find evidence that the firms that engage in the greatest amount of income-decreasing real earnings management experience the largest positive abnormal returns.

This study makes several contributions to the accounting and finance literatures. First, it contributes to the earnings management literature by demonstrating that firms use income- decreasing real earnings management, as opposed to just accruals-based earnings management, surrounding stock repurchases. The prior literature has focused mainly on firms’ use of accrual- based earnings management prior to repurchasing its shares (Gong et al. 2008). However, given that real earnings management is more costly to firms in terms of future cash flows effects
(Cohen and Zarowin 2010) and that the prevalence of real earnings management has increased since the passage of SOX (Cohen et al. 2008), it is important to document that firms manage their earnings through real activities manipulation preceding stock repurchases. An additional contribution to the earnings management literature is the fact that we examine a setting where firms use income-decreasing real earnings management instead of income-increasing real earnings management. Prior research generally focuses on instances in which managers are motivated to increase earnings (Roychowdhury 2006). However, the results of our study suggest that there are certain settings (i.e. stock repurchases) where managers have greater motivation to decrease earnings through the use of real earnings management.
Second, this study indicates that one means through which firms are able to minimize their costs associated with stock repurchases is by taking deliberate, suboptimal actions that lead to a reduction in the repurchase price. Specifically, managers increase spending on discretionary expenditures and produce fewer inventories than are needed to meet expected demand for the purpose of reporting lower earnings, in the hope that the market will undervalue its shares. This, in turn, will result in a reduced repurchase price. It is important that investors as well as regulators know that firms are participating in these types of non-value enhancing behaviors around stock repurchases because they can have long-term effects on firm value.
6
Finally, we show the tendency of firms to increase their use of real earnings management before a stock repurchase varies cross-sectionally. We find that the observed effect is larger for firms that are in strong financial health, those with greater stock options outstanding, and to a lesser extent, those with overvalued equity. This indicates the importance of considering managers’ motives for making firm decisions, such as stock repurchases, as well as identifying specific settings in which firms have a stronger motivation to engage in real earnings management.
The remainder of the paper is organized as follows. Section 2 describes the prior literature examining real earnings management and the management of earnings around corporate finance events. Section 3 develops our hypotheses. Section 4 describes our research design, and Section 5 presents our sample and the empirical results. Finally, Section 6 concludes.
2. The Prior Literature
2.1 Real Earnings Management
For the purposes of this study, we follow Roychowdhury (2006) and define real earnings management as “departures from normal operational practices, motivated by managers’ desire to mislead at least some stakeholders into believing certain financial reporting goals have been met in the normal course of operations (page 337).” For example, managers could choose to reduce discretionary expenditures on R&D in the current period in order to decrease reported expenses, and accordingly, increase earnings. While it is possible that deviations from the normal level of operational activities are optimal given firms’ economic conditions, the definition above requires firms to deviate more than normal, for the purpose of meeting and/or beating earnings benchmarks, for their actions to be considered real earnings management.
7
Survey evidence from Graham, Harvey, and Rajgopal (2005) suggests that managers behave in ways that are consistent with real earnings management. The authors report that approximately 80 percent of the 400 participating executives stated that they would decrease discretionary expenditures on R&D, advertising, and maintenance in order to meet an earnings benchmark. In addition, over 50 percent said that they would delay beginning a new project in order to meet an earnings target, even if it resulted in a small sacrifice in value. This suggests that managers take actions to increase earnings in the current period, potentially at the expense of the long-run value of the firm.4,5
Early archival studies confirming firms’ use of real earnings management primarily focused on investment activities, documenting that variations in firms’ R&D expenditures and asset sales are associated with meeting and/or beating various earnings benchmarks. Specifically,
Dechow and Sloan (1991) find executives spend less on R&D near the end of their tenure in order to increase short-term earnings, while Baber, Fairfield, and Haggard (1991) show firms reduce their spending on R&D expenditures in order to report positive or increasing income for the current period. In addition, Bartov (1993) demonstrates that firms with negative earnings changes report higher profits from the sale of long-lived assets and investments. Finally, it has been documented that institutional investors (Bushee 1998) and compensation committees
(Cheng 2004) mitigate firms’ willingness to reduce R&D expenditures in order to meet earnings targets.
4 Real earnings management activities can reduce the long-run value of a firm through their negative impact on future cash flows. For example, over-producing inventory will increase income for the current period by reducing the reported amount of cost of goods sold (by spreading fixed overhead costs over a greater number of units), but it will also lead to higher holding costs for the unsold units of inventory in future periods. 5 Prior research focuses on income-increasing real earnings management. Given the response to survey questions, it is also possible for managers to increase discretionary spending or reduce inventory production in order to decrease reported earnings. 8
More recent archival studies have expanded their scope and found evidence of real earnings management within firms’ various operational activities. For instance, Roychowdhury
(2006) finds firms offer price discounts to increase sales, reduce discretionary expenditures in
R&D, advertising, and SG&A to improve reported margins, and overproduce inventory to decrease cost of goods sold in order to manage earnings upward. Gunny (2010) confirms that firms reduce discretionary expenditures and manipulate sales in order to meet earnings benchmarks and shows that these firms have better future performance than those that do not participate in real earnings management and miss the earnings benchmark. Hence, evidence exists for firms’ use of real earnings management through a variety of operational activities.
The prevalence of real earnings management has been validated by comparing its use to another method of earnings management that has been widely studied in the prior literature, accruals-based earnings management.6 Specifically, Cohen et al. (2008) demonstrate that firms’ participation in real earnings management has increased, while their use of accruals-based earnings management has decreased, since the passage of SOX.7 In addition, Zang (2012) finds managers make a trade-off between the two earnings management methods based on their relative costs, while Baderstcher (2011) shows that firms’ choice between the two methods depends on the duration of overvaluation. The survey participants of Graham et al. (2005) also indicated that they prefer to manage earnings by taking real, as opposed to accounting, actions.
Thus, there is wide support for firms’ use of real earnings management as a tool to manage earnings.
2.2 Earnings Management around Corporate Finance Events
6 See Schipper (1989); Healy and Wahlen (1999); and Fields, Lyz, and Vincent (2001) for reviews of the accruals- based earnings management literature. 7 The authors propose that firms transitioned from using accruals-based earnings management to real earnings management because the later method is more difficult for auditors and regulators to detect. 9
The finance and accounting literatures contain extensive evidence of firms managing earnings upward around stock issuances.8 Both Teoh, Wong, and Rao (1998) and Teoh, Welch, and Wong (1998a) demonstrate that firms manage earnings through the use of income-increasing discretionary accruals prior to initial public offerings. Additionally, it has been found that firms use income-increasing discretionary accruals (Rangan 1998; Teoh, Welch, and Wong 1998b;
Shivakumar 2000) and real earnings management (Cohen and Zarowin 2010) to raise their stock price around seasoned equity offerings. With the exception of Shivakumar (2000) 9, the reasoning behind the earnings management decision is that if investors are unaware that a firm’s reported income number has been managed upward prior to the issuance, then they will overvalue its shares. This, in turn, will increase the firm’s proceeds from the stock issue.
In addition to the evidence indicating that managers use upward earnings management surrounding equity issuances, Gong et al. (2008) find that they use income-decreasing discretionary accruals around stock repurchases 10 . In this situation, managers’ objective is to reduce their firm’s stock price prior to a repurchase. Similarly to the scenario above, if investors are not aware that a firm has managed its reported earnings downward, then they will undervalue its shares, resulting in a lower repurchase price. Gong et al. (2008) reason that repurchasing stock at a lower price creates a transfer of wealth from the shareholders that are selling their shares to those that continue to hold stock in the firm. Managers benefit from this transfer as well, since their interests are more aligned with the remaining shareholders through their future
8 Managers have also been shown to use income-increasing discretionary accruals preceding stock-for-stock mergers (Erickson and Wang 1999; Louis 2004).
9 The author proposes that managing earnings before a seasoned equity offering is an issuer’s rational response because the market assumes this behavior once the offering has been announced and discounts the firms’ stock prices accordingly. 10 Managers also use income-decreasing discretionary accruals prior to announcing their intention of a management buyout (Perry and William 1994). The authors propose that shareholders may be willing to accept a lower buyout price if the firm appears to be less profitable. 10 compensation and equity interests in the firm. Therefore, the incentive exists for managers to take actions to reduce their firm’s stock price prior to making a repurchase.
The prior literature has illustrated that investors are unable to completely correct for the effects of earnings management on stock prices because they cannot directly observe managers’ actions and are uncertain about managers’ incentives (Louis 2004; Gong et al. 2008). In the case of stock repurchases, some managers use this action as a means of signaling favorable, private information to the market. If signaling is the intention behind a repurchasing decision, then it is less likely that managers will manage earnings downward prior to the repurchase. However, managers’ intentions are unobservable, which will cause investors to be uncertain as to whether a repurchase is being used as a signaling device or for a non-signaling purpose. Accordingly, they will be unable to fully adjust stock prices for the earnings management effect.
3. Hypothesis Development
3.1 Real Earnings Management and Stock Repurchases
As discussed in Section 2, managers repurchasing shares for a non-signaling purpose have an incentive to reduce their firm’s stock price prior to making the repurchase: the lower the value of the stock immediately preceding the repurchase, the less amount of cash that must be paid to repurchase their shares. One approach that firms can take to lower their stock price prior to a repurchase is to take actions to manage earnings downward. Since investors cannot observe management’s intent for the repurchase decision, they will be unable to fully correct the stock price for the earnings management effect, causing them to undervalue the firm’s stock. In support of this claim, Gong et al. (2008) show that firms use income-decreasing discretionary accruals around stock repurchases. However, another tool at their disposal is real earnings
11 management, which the prior literature has shown is a substitute to accruals-based earnings management, and in at least some cases, is managers’ preferred method of managing earnings
(Graham et al. 2005; Cohen et al. 2008; Baderstcher 2011; Zang 2012).
This study hypothesizes that firms use two specific methods of income-decreasing real earnings management before repurchasing their shares for a non-signaling purpose: under- producing inventory and increasing discretionary expenditures.11 Under the first method, firms choose to produce fewer inventories than is necessary to meet expected demand. The lower level of production results in fixed overhead costs being divided over a smaller number of units, increasing fixed costs per unit, and correspondingly, increasing the total cost per unit.12 This, in turn, increases the cost of goods sold, and results in a lower reported earnings number. If investors are unaware that a firm’s earnings appear low as a result of downward real earnings management, then they will reduce their value of its stock.13 Accordingly, if a firm aspires to depress its stock price prior to a repurchase, then we predict that it will under-produce its inventory. This is formally stated in the following hypothesis:
H1a : On average, firms under-produce their inventory in the period prior to a stock repurchase.
The second method of real earnings management that managers can use to lower their reported earnings number is increased discretionary spending on R&D, advertising, and SG&A.
These types of expenditures are generally expensed during the period in which they are incurred.
Therefore, increasing discretionary spending on these items will increase expenses for the current period, and consequently, decrease reported earnings. If investors are similarly unaware
11 Extensive support exists for the use of both of these methods of real earnings management by firms. Refer to the previous section for examples of studies that have found collaborating evidence. 12 This assumes that the increase in fixed cost per unit is not offset by a decrease in the marginal cost per unit. 13 Consistent with the results of the prior research discussed in footnote two, we assume that investors do not see through real earnings management prior to a stock repurchase. 12 of a firm’s use of this method of downward real earnings management, then they will likewise lower the value of its stock. Therefore, we predict that a firm will increase its discretionary expenditures if it aspires to reduce its stock price prior to a repurchase. This is formally stated in the following hypothesis:
H1b: On average, firms increase their discretionary expenditures in the period prior to a stock repurchase.
Real earnings management occurs when managers make departures from the optimal level of operating activities. However, they may want to avoid the use of income-decreasing real earnings management for several reasons. First, managers are pressured to report positive earnings, show positive changes in earnings, and meet analyst forecasts. Accordingly, they may be unwilling to take actions that retract from meeting these earnings benchmarks. Managers may also be hesitant because of the potential decline in long-run firm value resulting from the cash flow effects of real earnings management. Additionally, a loss of reputation in the job market may develop for managers that are known to manage earnings (Desai, Hogan, and Wilkins 2006).
Therefore, it may be possible that we find no association between real earnings management and subsequent stock repurchases. We expect, however, that the benefits of engaging in income- decreasing real earnings management around non-signaling stock repurchases will exceed these potential costs.
3.2 Cross-Sectional Variation in Real Earnings Management Hypotheses
In addition to determining whether firms, on average, increase their use of income- decreasing real earnings management prior to non-signaling stock repurchases, this study examines whether the association varies cross-sectionally. The first subset of firms that we consider includes those that are in strong financial health. Zang (2012) demonstrates that firms
13 with stronger financial health can participate in real earnings management at a lower cost compared to firms in weaker financial health. If a firm is financially strong, then it will have more resources to rely on and greater opportunities to participate in real earnings management activities. For instance, a financially healthy firm will have more resources available to allocate to increased discretionary expenditures, compared to other firms. In addition, financially stable firms are better able to absorb the financial hit of producing fewer inventories than are needed to meet expected demand than firms that are less financially stable. Accordingly, we predict that firms in strong financial health participate in more income-decreasing real earnings management in the period prior to a stock repurchase than the average firm. This is formally stated in the following hypotheses:
H2a : Firms in strong financial health under-produce their inventory in the period prior to a stock repurchase to a greater extent than the average firm.
H2b : Firms in strong financial health increase their discretionary expenditures in the period prior to a stock repurchase to a greater extent than the average firm.
The argument that is outlined above for why managers engage in income-decreasing real earnings management prior to stock repurchases assumes that the repurchase decision was made for non-signaling purposes 14 . If managers’ decision to repurchase shares is primarily driven by a desire to signal favorable, new information about the future value of the firm, then the price at which they buy back their shares may not be a principle concern. As such, we examine two sets of firms that are more likely to take their shares’ price into account when making a repurchase
14 Gong et al. (2008) compiles an extensive list of non-signaling reasons that managers conduct stock repurchases, including: the distribution of excess cash to shareholders (Brennan and Thakar 1990); the reduction of agency costs (Denis and Denis 1993; Grullon and Michaely 2004); the maximization of the value of employee stock options (Jolls 1998); the financing of employee stock option plans (Kahle 2000); a change toward a firm’s optimal financial leverage (Dittmar 2000); and the expropriation of creditors (Maxwell and Stephens 2003). 14 decision: firms with a significant amount of outstanding stock options and those with overvalued equity.
Accordingly, the third set of hypotheses examines the cross-sectional differences based on the amount of stock options outstanding. Kahle (2002) finds that the existence of stock options leads firms to make repurchases in order to have shares available to fund employee stock option plans. By combining stock repurchases with stock option exercises, firms are able to avoid diluting their basic earnings per share (EPS). Since the main purpose for the repurchase is to fund employee stock option plans, we expect that they will want to accomplish this as cheaply as possible. Therefore, we predict that firms with greater stock option intensity will be more motivated to depress their stock price prior to making a stock repurchase, and accordingly, will participate in more downward real earnings management. This discussion is formalized in the following hypotheses.
H3a: Firms with greater stock options outstanding under-produce their inventory prior to a stock repurchase to a greater extent than the average firm.
H3b : Firms with greater stock options outstanding increase their discretionary expenditures in the period prior to a stock repurchase to a greater extent than the average firm.
The final subset of firms consists of those that are overvalued. Jensen (2005) defines equity as being overvalued when “a firm’s stock price is higher than its underlying value (5).”
We predict that a firm with overvalued equity will be more likely to manage earnings downward prior to making a stock repurchase than an undervalued firm 15 . First, prior studies (Ikenberry et
15 The prior literature examining the earnings management behavior of overvalued firms has generally found that they engage in income-increasing earnings management (Efendi, Srivastava, and Swanson 2007; Chi and Gupta 2009; Badertscher 2011):. This is consistent with Jensen’s (2005) agency cost theory of overvalued equity, that firms manage earnings in an effort to sustain their overvaluation. We expect, however, that managers’ incentive to 15 al. 1995; Kahle 2002) find evidence consistent with undervalued firms making repurchases for signaling purposes. In addition, a firm with undervalued equity has little incentive to use real earnings management to lower its stock price prior to making a stock repurchase because it is already at a low level. In contrast, a firm with overvalued equity 16 has a high stock price, relative to its underlying value, and therefore, can achieve a larger reduction in the repurchase price by participating in income-decreasing real earnings management activities prior to making a stock repurchase. This is formally restated in the following hypotheses.
H4a: Firms that are overvalued based on the price-to-value ratio under-produce their inventory prior to a stock repurchase to a greater extent than the average firm.
H4b: Firms that are overvalued based on the price-to-value ratio increase their discretionary expenditures in the period prior to a stock repurchase to a greater extent than the average firm.
4. Research Design
4.1 Real Earnings Management
Real earnings management is measured similarly to Roychowdhury (2006), Cohen and
Zarowin (2010), and Zang (2012). Specifically, we examine two methods of real earnings management.17 The first method is reporting lower cost of goods sold through increased production. A firm can over-produce its inventory, which will result in a lower cost of goods sold,
lower the repurchase price of their shares will outweigh their motive to continue the upward trend in their stock price. 16 The determination of whether a firm is overvalued is based on its price-to-value ratio, which is estimated using the EBO residual income model of Edwards and Bell (1961) and Ohlson (1995). This is further discussed in the next section. 17 Consistent with Zang (2012), we do not examine abnormal cash flows from operations, because, as discussed in Roychowdhury (2006), real earnings management impacts this in different directions and the net effect is ambiguous. For example, price discounts, channel stuffing, and over-production all decrease cash flows from operations, while cutting discretionary expenditures increases them. 16 and thus, increase current period income. The second method is to decrease discretionary expenses, including R&D, advertising, and SG&A expenses. If managers choose to decrease these expenditures, then they will consequently increase current period earnings. Given that the purpose of the study is to examine firms’ income-decreasing , rather than income-increasing , activities, the intuition will run opposite of the prior literature. That is, we expect firms to decrease production and increase discretionary expenses, both of which are income-decreasing activities. Following Roychowdhury (2006), we use equations (1) and (2) to estimate normal levels of production and discretionary expenses.
