The Sarbanes-Oxley Act (SOX) was intended to protect investors by improving the accuracy and reliability of corporate disclosures. However, critics have argued that the costs of SOX far outweigh its intended benefits. Prior studies based on stock-price reactions to SOX-related events document mixed evidence on the expected impact of SOX. In contrast, we provide evidence on the net realized costs of SOX by examining its impact on operating profitability. We find that average cash flows decline by 1.3% of total assets after SOX. These costs are more significant for smaller firms, for more complex firms, and for firms with lower-growth opportunities. Annually, these costs range from $6 million for smaller firms to $39 million for larger firms. Further, we document that net SOX-related costs are not limited to one-time expenses associated with internal-control design and implementation. In aggregate, for the 1428 firms in our sample, these costs amount to about $19 billion per year. Profitability is lower for up to four years post-SOX. To our knowledge, ours are the first estimates of the realized net costs imposed by SOX.  相似文献

Interfirm collaboration is an important strategy for firms to generate new products and services. Whereas existing research emphasizes the importance of interfirm collaboration engagement to realize synergistic benefits in interfirm NPD projects, it remains surprisingly silent on the potential impact of intrafirm relational processes and how they can impact the interfirm setting. In this article, we therefore explore the impact of intrafirm collaboration engagement on the relationship between interfirm collaboration engagement and new product development (NPD) performance in interfirm NPD projects. Relying on insights from information processing theory, the authors hypothesize that intrafirm collaboration engagement increases firms' capacity to process complex information flows in the case of extensive interfirm collaboration engagement. Moreover, it is expect that the added value of extensive intrafirm collaboration engagement depends on the innovation objective (i.e., incremental versus radical new product development) of the interfirm NPD project. In particular, we hypothesize that the positive moderating impact of intrafirm collaboration engagement on the relationship between interfirm collaboration engagement and NPD performance is stronger for radical interfirm projects than incremental interfirm projects. Analyzing 195 interfirm NPD projects, a negative interaction effect between interfirm and intrafirm collaboration engagement is observed in radical interfirm NPD projects, whereas significant interactions between them remain absent in incremental interfirm NPD projects. Jointly, these findings provide first evidence that intrafirm relational processes can substantially impact partners' ability to realize relational rents in interfirm settings. Moreover, the negative interaction effect between interfirm and intrafirm collaboration engagement points to potential trade‐offs between inward‐looking and outward‐looking absorptive capacity.  相似文献

The satellite accounts illustrated in this paper reflect the household's role as a producer and an investor in durables as well as a consumer by modifying the NIPA's to (1) incorporate the value of nonmarket (unpaid) household work into GDP; and (2) treat expenditures on consumer durables as investment and measure the value of the services those durables provide. Additionally, an Input–Output (I–O) model highlights the household's functions as a producer and investor in much greater detail for the year 1992 by incorporating a household industry for each time-use activity and by showing the inputs to and outputs from each household industry's production.  相似文献

The influence of index trading on price levels, returns, spreads or volatility in agricultural commodity markets is frequently investigated with bivariate Granger Causality (GC) tests. A joint review of existing empirical studies reveals scant and inconsistent evidence of GC from index activity to prices. Some findings of reverse GC from prices to index activity are reported. The literature offers three different interpretations of GC test results: (i) as prima facie causal evidence; (ii) as a test for informational efficiency of the markets; or (iii) as a test for the ability of one variable to improve the forecast of another variable. A critical examination of these interpretations against an extended theoretical background reveals that none allows direct inferences about the existence or absence of an influence from index trading activity on the price mechanism in the market. This severely limits the usefulness of a stand‐alone application of GC tests.  相似文献

In the course of the economic catching-up process of the new EU states, the capital cities of the countries in central and eastern Europe were the economically most successful regions in their countries. How distinct are economic disparities between the capitals and the rest of the countries today? What were the determinants of the related economic developments? And do current economic trends support the leading position of the capital cities in the new member states?   相似文献

Road-kills are a major cause of mortality for a wide variety of herpetofauna, but management decisions on remediation procedures for reducing losses are based in economic realities. Because funding is finite for species conservation, bioeconomic analysis can assist in justifying, evaluating, and maximizing returns on conservation expenditures, especially for low-profile species such as herpetofauna. Here, we present a bioeconomic analysis of road-killed herpetofauna in Jonathan Dickinson State Park, Florida. Road surveys were conducted daily for four years to identify and enumerate the numbers of each reptile and amphibian species killed by vehicles. Conservative individual valuations applied to the losses formed the basis of a benefit-cost analysis aimed at identifying the thresholds at which remediation expenditures would be justified. We found an average of 64 reptiles and amphibians were killed/year, justifying conservation expenditures up to $32,000/year. However, if less conservative valuations were applied, especially for threatened and endangered species, justifiable expenditures rise dramatically.  相似文献

A hedonic model was developed to analyze the market for undeveloped forest land in Minnesota. Variables describing in situ conditions, locational characteristics, buyer perceptions and intentions, and transactional terms were tested for their influence on sale price. The independent variables explained 67% of the per hectare sale price variation. Water frontage, road access and density, absentee ownership, future intentions, and financing arrangements had large, positive influences on price. Lack of a real-estate agent and agricultural land in the vicinity of the parcel had negative influences. A parcel's merchantable timber volume was not a significant predictor of price.  相似文献
