We empirically examine changes in information asymmetry and informational efficiency of cross‐listed stocks in their home market around a cross‐listing in the United States. We estimate intraday market microstructure measures of information asymmetry and price efficiency, and find that a U.S. cross‐listing significantly improves the quality of a firm's information environment and stock price efficiency in the home market. This improvement is stronger for cross‐listings that take place after the adoption of Sarbanes‐Oxley Act. Our results demonstrate that stricter disclosure from a U.S. cross‐listing is beneficial, in line with the legal and reputational bonding hypotheses.  相似文献

Prior work argues that the “market for ideas” supports an open system of innovation, allowing for efficient development of technology across firms. Although this literature has described important features of this market, how it influences the rate and direction of innovation remains an open question. We exploit an exogenous shock to a subset of U.S. medical device firms to study this question. We first document the breakdown in the market for ideas after a federal investigation made it more difficult for the leading orthopedic firms to work with physician‐inventors. We then present evidence of a dramatic decline in the rate of innovation for these firms. Further, a marked shift in direction occurs toward lower‐quality inventions and away from product categories where physician knowledge is critical. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

When stocks are ranked by returns in one month, the portfolio of loser stocks tends to outperform the portfolio of winner stocks in the subsequent month. Yet industry portfolios tend to display momentum. We develop a model of information diffusion among agents with constrained information processing ability that reconciles these well-documented phenomena. We test whether this model or the overreaction hypothesis is consistent with the data. Additionally, a trading strategy based on the model outperforms strategies based on overreaction and on industry momentum. The strategy produces abnormal returns while controlling for marketrisk and the size, book value, January, momentum, and liquidity effects.  相似文献

In the era of the global economy, knowledge‐based services are becoming important sectors of the service industry. Services offered by a university are knowledge‐based services. Universities are in the service business, and they play a key role in creating and disseminating knowledge through teaching, research, and related services that cross domestic borders. The current research focuses on the internationalization of US MBA programs. The internationalization of US MBA programs refers to the delivery of knowledge‐based services beyond the domestic borders. The main objective of our research is to examine the effect of an organization's (e.g., a US business school) resources and a host country's attractiveness on the internationalization of knowledge‐based services offered by a firm (a US business school). Using data gathered from MBA programs of US colleges and universities, theÊstudy findings show that internationalization is influenced by human capital, prestige and reputation, management's willingness, and foreign market attractiveness. The results of this study offer practical insights for US business school leaders. © 2014 Wiley Periodicals, Inc.  相似文献

Strategic project management is gradually becoming a popular and growing trend within the discipline of project management. The general idea is that project management teams must learn how to deal with the business aspects of their projects, as well as better support their company's business strategy and sustainability, rather than just focus on meeting traditional time, budget, and performance goals. Although this approach has been gaining popularity, strategic project management has not yet become an explicit and widely used approach in the practice of project implementation. One of the concepts mentioned as an important element is project strategy; however, no universal framework or even a clear definition of what project strategy is has so far emerged. The goal of this article is to fill in this gap and provide a useful definition and a framework for the further study and implementation of the project strategy concept. Specifically, to achieve this goal, we first look at the origins of strategy in military and business research to discuss the question of what, exactly, project strategy is; we follow this discussion with an explicit definition of a project strategy. We then outline a framework for building a dedicated project strategy document for an individual project, and show how this framework can guide the project planning and execution processes. Using a case study approach, which included an action research phase, we demonstrate how project teams can adopt the strategy concept in a natural way that would lead their project to better business results.  相似文献

We provide evidence on the real-time predictive content of the National Financial Conditions Index (NFCI), for conditional quantiles of U.S. real GDP growth. Our work is distinct from the literature in two specific ways. First, we construct (unofficial) real-time vintages of the NFCI. This allows us to conduct out-of-sample analysis without introducing the kind of look-ahead biases that are naturally introduced when using a single current vintage. We then develop methods for conducting asymptotic inference on tests of equal tick loss between nested quantile regression models when the data are subject to revision. We conclude by evaluating the real-time predictive content of NFCI vintages for quantiles of real GDP growth. While our results largely reinforce the literature, we find gains to using real-time vintages leading up to recessions—precisely when policymakers need such a monitoring device.  相似文献

Incentives in agriculture are highly distorted. It has long been argued that these distortions were a key explanation for differences in supply and productivity across countries, but the empirical evidence is limited. We revisit this issue using data on policy distortions across 63 countries for the period 1961–2011. We estimate the effects of differential changes in agricultural distortions across countries on supply and productivity. We highlight concerns in our analysis and previous work about endogeneity that biases the estimated effect downward—countries that lose comparative advantage are likely to increase support for agriculture. We address these concerns by including country and region-time fixed effects, along with a rich set of controls. Overall, we find evidence that enhanced incentives through policy changes can increase the rate of production growth, with about half of the increase due to productivity increases. This result is strongest in Sub-Saharan Africa where anti-agricultural policies on exports were reduced and in Europe where pro-agricultural policies on imports were reduced, driven largely by external pressure. Endogeneity appears to be strongest in Asia where countries have followed the typical pattern of raising support for agriculture during industrialization due to a rising farm-urban income gap.  相似文献
