This paper examines the impact of quantity-discounted transportation rates on location patterns of oligopolistic competition with sequential entry. When transportation rates are constant, Hwang and Mai (1990) show that the entrant locates at the same point as the existing firms if the production function exhibits constant returns to scale. The entrant will locate farther away from (closer to) the market than the existing firms do if the production function exhibits increasing (decreasing) returns to scale. This paper shows that Hwang and Mai's results need not hold when transportation rates are a function of quantity shipped and distance traveled.  相似文献

We analyze the choice between the origin and destination principles of taxation when there is product differentiation and Bertrand competition. If taxes are redistributed to consumers and demand is linear the origin principle dominates the destination principle whatever the degree of product differentiation and extent of economic integration. With nonlinear demand the origin principle dominates if there is sufficient economic integration. When the social value assigned to tax revenue is higher than the private value, the destination principle dominates for intermediate values of product differentiation and economic integration. The same results are also shown to hold with Cournot competition. JEL Code: F12, H20  相似文献

This article analyzes the behavior of an oligopoly of risk-averse insurers that insure many consumers facing identical independent risks; however, the probability of a loss is ex ante not known with certainty. It is shown that there is a continuum of equilibria in the Bertrand game. The most plausible equilibrium can be obtained by requiring that all insurers are content with the number of policies they sell given the equilibrium premium.  相似文献

In this study, we examine whether managerial ability moderates the association between product market competition and real earnings management. Prior literature largely supports the disciplinary effect of competition, suggesting that competition reduces real activity manipulation. We argue that this association is different depending on the level of managerial ability. Based on the reputation hypothesis, we argue that able managers negatively moderate the association between competition and real activity manipulation. Using a sample of US listed companies from 1997 to 2016, we find evidence to support our moderating assertion. A battery of robustness tests validates our original findings.  相似文献

The numerous variations of the particle swarm optimization (PSO) algorithm originally proposed by Kennedy and Eberhart ( 1995 . Particle swarm optimization. In Proceedings of the IEEE International Conference on Neural Networks IV. IEEE: Piscataway, NJ; 1942–1948) have proven to be powerful optimization methods that rely on exploiting simple analogues of social interaction. In this study, PSO is adopted in lieu of the social or individual evolutionary learning algorithms as a model of individual adaptation in an agent-based computational model. In this examination of the simple Cournot market framework, each agent's individual strategy evolves according to the PSO algorithm. The model is one in which agents’ strategies must adapt interdependently. That is, a change in one particle may not only affect its performance but also other particles within the same swarm simultaneously. The dynamics and convergence properties associated with this model are compared with those where evolutionary learning algorithms are employed. Similar to evolutionary learning, convergence to equilibrium is dependent on the scope of learning, social or individual. While convergence is dependent on some of the algorithm parameters, prices resulting from the individual PSO are nearest the Cournot equilibrium and those from social PSO are nearest the Walrasian equilibrium in all cases. For particular parameterizations, certain advantages over evolutionary algorithms exist: in the main, decreasing volatility in market prices does not require an election operator or the addition of free parameters through two-level learning.

Prior literature has investigated three forms of earnings management: real earnings management (REM), accruals earnings management (AEM) and classification shifting. Managers make trade‐off decisions among these methods based on the costs, constraints and timing of each strategy. This study investigates whether managers use classification shifting when their ability to use other forms of earnings management is constrained. We find that when REM is constrained by poor financial condition, high levels of institutional ownership and low industry market share, managers are more likely to use classification shifting. Further, we find that when AEM is constrained by low accounting system flexibility and the provision of a cash flow forecast, managers are more likely to use classification shifting. In addition, when we limit our sample to firms that are most likely to have manipulated earnings, we continue to find support for constraints of both REM and AEM leading to higher levels of classification shifting. We also find support for the hypothesis that the timing of each earnings management strategy influences managers’ trade‐off decision. Our results indicate that managers use classification shifting as substitute form of earnings management for both AEM and REM.  相似文献

We examine whether the choice of earnings management strategies employed by managers of overvalued firms depends on the degree of market overvaluation. By distinguishing between substantially overvalued (SOV) and relatively overvalued (ROV) firms, we find that SOV firms significantly inflate earnings using both accruals-based and real earnings management. In contrast, managers of ROV firms do not engage in accruals-based earnings management and their firms’ accounts tend to report higher discretionary expenses. The reported higher discretionary expenses of ROV firms are comparable to the discretionary expenses of firms in the expanding stage of their business life cycle, a pattern consistent with ROV firms increasing discretionary expenses to finance growth and hence justify the high market valuation. Overall, we show that the existing evidence on income-increasing earnings management by overvalued firms is mainly driven by the pressure to sustain the high market valuation of firms that are substantially overvalued.  相似文献

We examine whether and how political embeddedness influences financial reporting quality in China by investigating how government ownership and political connections affect Chinese listed firms’ choices of earnings management strategies. The results show that state-owned enterprises (SOEs), and in particular, central SOEs, are more likely to substitute accrual-based earnings management strategies with costlier but less detectable real earnings management strategies than non-SOEs. The results also indicate that politically connected enterprises (PCEs) are more likely to employ less detectable real earnings management strategies than non-PCEs, so much so that PCEs’ total earnings management level is higher than that of non-PCEs.  相似文献

Measurement error in unexpected accruals is an important problem for empirical earnings management research. Several recent studies avoid this problem by examining the pooled, cross–sectional distribution of reported earnings. Discontinuities in the distribution of reported earnings around key earnings thresholds may indicate the exercise of management discretion (i.e. earnings management). We apply this approach to the detection of earnings management by Australian firms. Our results generally indicate significantly more small earnings increases and small profits than expected and conversely, considerably fewer small earnings decreases and small losses than expected. These results are much stronger for larger Australian firms. We undertake an exploratory analysis of alternative explanations for our results and find some evidence consistent with management signalling its inside knowledge about the firm's expected future profitability to smooth earnings, as opposed to 'management intent to deceive' as an explanation for our results.  相似文献

We present an agent‐based model of endogenous merger formation in a market with turnover of market participants. We describe the dynamics of the model and identify the conditions under which market competition is sufficiently disrupted to prompt extended periods during which mergers are desirable. We also demonstrate how merger waves can be triggered by industry shocks and firm overconfidence. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Taking into account agency problems between board and management within non‐profit organisations, for the first time a comprehensive formal model of earnings manipulations is developed. Both organisational earnings as well as disaggregated financial performance indicators are looked at, the last ones being affected by possible indirect cost allocation manipulations. The model takes into consideration the impact of disclosed earnings and performance indicators on externally raised funds, and assumes risk‐neutral managers. In the last section, it is generalised by introducing risk‐averse managers.

The conditions for optimal manipulation levels (from a managerial point of view) are derived. Depending on the (dis) utility parameters involved, different solutions emerge. As to the agency problems, it is shown that, at least for all interior solutions, a single mechanism is at work in all the situations analysed: more agency problems lead to more manipulations, both at the organisational level and the disaggregated level.  相似文献

The widespread use of rank and file equity‐based compensation suggests that executives believe that rank and file employees can affect firm outcomes, and some research supports this view. If equity‐based incentives influence rank and file employees’ productive efforts, they might also influence their earnings management decisions. We find that increases in rank and file employees’ option‐based compensation—our proxy for equity‐based compensation—are associated with increases in earnings management and that this relation is attributable to real activities (as opposed to accrual) earnings management. Cross‐sectional tests indicate that the relation is stronger when rank and file option compensation is likely to generate greater performance incentives and attenuated in the presence of more intense monitoring. Finally, we explore the role of cash constraints and overvaluation as potential alternative explanations for this relation and find that neither accounts for our results.  相似文献

The Panzar–Rosse H statistic is a commonly used measure of market power in banking. It is widely believed that H>0 is inconsistent with significant market power. This study rigorously disproves that perception. Instead, the possibility of H>0 under conditions of substantial market power turns out robust to the timing of banks’ actions, relative costs, choice of strategic variable, degree of product differentiation, strategy (static or dynamic), and degree of heterogeneity in banks’ conduct (collusive versus fringe), and hence may be common in practice.  相似文献

Employing a large sample of 13,860 firms in 41 economies from 2000 to 2017, we document that the ownership by foreign institutional investors (FIIs) is negatively associated with firms' real earnings management (REM) but unrelated to their accrual earnings management (AEM). We adopt a few identification strategies to tackle the endogeneity issues, including firm- and year-fixed effects regression, two-stage least squares (2SLS) regression, and difference-in-differences (DiD) estimation based on the passage of the Jobs and Growth Tax Relief Reconciliation Act (JGTRRA). In addition, we show that the role of FIIs in curbing REM is achieved through the expertise channel and the monitoring channel. These results suggest that when facing disadvantages in curbing AEM, FIIs make the most of their monitoring strengths by curbing firms' REM, where they have both incentives and capabilities to monitor. Overall, this study highlights the important role of FIIs in monitoring opportunistic managerial behaviour.  相似文献

Prior research suggests that managers may use earnings management to meet voluntary earnings forecasts. We document the extent of earnings management undertaken within Canadian Initial Public Offerings (IPOs) and study the extent to which companies with better corporate governance systems are less likely to use earnings management to achieve their earnings forecasts. In addition, we test other factors that differentiate forecasting from non‐forecasting firms, and assess the impact of forecasting and corporate governance on future cash flow prediction. We find that firms with better corporate governance are less likely to include a voluntary earnings forecast in their IPO prospectus. In addition, we find that while IPO firms use accruals management to meet forecasts; the informativeness of the discretionary accruals depends on whether or not the firm would have missed its forecast without the use of discretionary accruals.  相似文献

Abstract:  This paper corroborates the finding of prior studies that managers avoid reporting earnings lower than analyst forecasts (i.e., negative earnings surprises) and provides new evidence of actions contributing to this phenomenon. Specifically, we provide empirical evidence of both (1) upward management of reported earnings and (2) downward 'management' of analysts' forecasts to achieve zero and small positive earnings surprises. Further analysis of the components of earnings management suggests that both the operating cash flow and discretionary accruals components of earnings are managed.  相似文献

将盈余管理细分为应计盈余管理、线上真实盈余管理和线下真实盈余管理,基于我国特有的配股管制变迁环境,考察监管者识别盈余管理的能力及其变化。研究发现,监管者对上市公司盈余管理具有一定的识别能力,但是会受到管制环境变迁的影响,存在管制效应和演进效应。具体而言,在审核配股资格过程中,监管者能识别线下真实盈余管理,但是,在管制环境变迁后,由于线下真实盈余管理被纳入管制范围,监管者不再对其进行关注,而是关注应计盈余管理,并能识别。在线上真实盈余管理方面,由于其隐蔽性强,监管者并没有表现出显著的识别能力。  相似文献
