AbstractThis paper describes improvements on methods developed by Burgstahler and Dichev (1997, Earnings management to avoid earnings decreases and losses, Journal of Accounting and Economics, 24(1), pp. 99–126) and Bollen and Pool (2009, Do hedge fund managers misreport returns? Evidence from the pooled distribution, Journal of Finance, 64(5), pp. 2257–2288) to test for earnings management by identifying discontinuities in distributions of scaled earnings or earnings forecast errors. While existing methods use preselected bandwidths for kernel density estimation and histogram construction, the proposed test procedure addresses the key problem of bandwidth selection by using a bootstrap test to endogenise the selection step. The main advantage offered by the bootstrap procedure over prior methods is that it provides a reference distribution that cannot be globally distinguished from the empirical distribution rather than assuming a correct reference distribution. This procedure limits the researcher's degrees of freedom and offers a simple procedure to find and test a local discontinuity. I apply the bootstrap density estimation to earnings, earnings changes, and earnings forecast errors in US firms over the period 1976–2010. Significance levels found in earlier studies are greatly reduced, often to insignificant values. Discontinuities cannot be detected in analysts’ forecast errors, while such findings of discontinuities in earlier research can be explained by a simple rounding mechanism. Earnings data show a large drop in loss aversion after 2003 that cannot be detected in changes of earnings. 相似文献

We propose a methodology for combining several sources of model and data incompleteness and partial identification, which we call Composition Theorem. We apply this methodology to the construction of confidence regions with partially identified models of general form. The region is obtained by inverting a test of internal consistency of the econometric structure. We develop a dilation bootstrap methodology to deal with sampling uncertainty without reference to the hypothesized economic structure. It requires bootstrapping the quantile process for univariate data and a novel generalization of the latter to higher dimensions. Once the dilation is chosen to control the confidence level, the unknown true distribution of the observed data can be replaced by the known empirical distribution and confidence regions can then be obtained as in Galichon and Henry (2011) and Beresteanu et al. (2011). 相似文献

Through utilising currently available Internet technologies, academic and governmental organisations can provide seedling
companies in their incubators with additional competitive advantage through efficient access to markets, partners, knowledge
and services both locally and globally. This paper proposes a Triple Helix approach for brokering social and human capital
based on the skills brokerage business model. The skills brokerage business model is primarily suited for individuals and
firms operating in localised settings. However, by using information and communication technologies, it is also possible to
apply the model internationally for firms that need strategic partnerships in countries or regions other than their own. Coupled
with the Triple Helix of university–government–industry interactions, it can propel innovation and the commercialisation of
it beyond traditional boundaries of geography, such as the region and nation state. The paper also presents an Internet-based
service that could be used to facilitate the brokerage process among the firms and people with relevant expertise and resources,
and it discusses the implications this would have for a number of stakeholders, such as entrepreneurs, established businesses,
service providers and business support organisations. This is still an emerging area and several themes for future research
will be highlighted. 相似文献

A stock market liberalization is a decision by a country's government to allow foreigners to purchase shares in that country's stock market. On average, a country's aggregate equity price index experiences abnormal returns of 3.3 percent per month in real dollar terms during an eight-month window leading up to the implementation of its initial stock market liberalization. This result is consistent with the prediction of standard international asset pricing models that stock market liberalization may reduce the liberalizing country's cost of equity capital by allowing for risk sharing between domestic and foreign agents. 相似文献

Launch Decisions and New Product Success: An Empirical Comparison of Consumer and Industrial Products 总被引:2,自引:0,他引:2

Many articles have investigated new product development success and failure. However, most of them have used the vantage point of characteristics of the product and development process in this research. In this article we extend this extensive stream of research, looking at factors affecting success; however, we look at the product in the context of the launch support program. We empirically answer the question of whether successful launch decisions differ for consumer and industrial products and identify how they differ. From data collected on over 1,000 product introductions, we first contrast consumer product launches with industrial product launches to identify key differences and similarities in launch decisions between market types. For consumer products, strategic launch decisions appear more defensive in nature, as they focus on defending current market positions. Industrial product strategic launch decisions seem more offensive, using technology and innovation to push the firm to operate outside their current realm of operations and move into new markets. The tactical marketing mix launch decisions (product, place, promotion and price) also differ markedly across the products launched for the two market types. Successful products were contrasted with failed products to identify those launch decisions that discriminate between both outcomes. Here the differences are more of degree rather than principle. Some launch decisions were associated with success for consumer and industrial products alike. Launch successes are more likely to be broader assortments of more innovative product improvements that are advertised with print advertising, independent of market. Other launch decisions uniquely related to success per product type, especially at the marketing mix level (pricing, distribution, and promotion in particular). The launch decisions most frequently made by firms are not well aligned with factors associated with higher success. Additionally, comparing the decisions associated with success to the recommendations for launches from the normative literature suggests that a number of conventional heuristics about how to launch products of each type will actually lead to failure rather than success. 相似文献

Economic policy is commonly treated as a vehicle for selecting among possible allocative outcomes within an economy. An economy, however, is a complex network of relationships whose patterns can be understood but whose details can be neither predicted nor controlled. Because of this complexity, allocative outcomes are not direct objects of choice. They are simply emergent consequences of human interaction that takes place within some framework of governing rules and conventions. All economic policy can do is modify some of the rules that govern this interaction. Economic policy is thus constitutive and not allocative in character, being centrally involved in shaping the character of the regime that governs our relationships with each other. 相似文献
