This study investigates the correlation between food insecurity, educational achievement, and health among kindergarten children in the United States. Data from the Early Childhood Longitudinal Study—Kindergarten Cohort are used to analyze educational achievement and physical growth of kindergartners faced with food insecurity. The results demonstrate that children begin to experience the effects of food insecurity even at the most marginal level of household food deprivation. Children in households with any signs of food insecurity score lower and learn less during the school year.  相似文献

We study whether the sealing of a defendant’s judicial records during a patent lawsuit filing correlates with the defendant’s level of competition and disclosure. Courts permit sealing of judicial records when competitive damage outweighs the public interest in access to documents and records. We find that defendants with sealed judicial records have higher research and development (R&D), lower industry sales concentration, and more references to competition in their annual reports than defendants without sealed judicial records. We observe faster mean reversion of return on net operating assets when courts seal defendant records. The results suggest that sealing relates to archival measures of competition. Finally, consistent with proprietary costs restraining disclosure, we find that defendants with sealed judicial records are less likely to issue management forecasts, file 8-Ks less frequently, and have longer and less readable 10-Ks.  相似文献

There is ample justification for the consensus view that the Horizontal Merger Guidelines have proven one of antitrust law??s great successes in the grounding of antitrust doctrine within economic learning. The foundation of the Guidelines?? success has been its widespread adoption by federal courts, which have embraced its rigorous underlying economic logic and analytical approach to merger analysis under the Clayton Act. While some have suggested that the Guidelines?? most recent iteration might jeopardize this record of judicial adoption by downplaying the role of market definition and updating its unilateral effects analysis, we believe that these updates are generally beneficial and include long-overdue shifts away from antiquated structural presumptions in favor of analyzing competitive effects directly where possible. However, this article explores a different reason to be concerned that the 2010 Guidelines may not enjoy widespread judicial adoption: the 2010 Guidelines asymmetrically update economic insights underlying merger analysis. While the 2010 Guidelines?? updated economic thinking on market definition and unilateral effects will likely render the prima facie burden facing plaintiffs easier to satisfy in merger analysis moving forward, and thus have significant practical impact, the Guidelines do not correspondingly update efficiencies analysis, leaving it largely as it first appeared 13 years earlier. We discuss two well-qualified candidates for ??economic updates?? of efficiencies analysis under the Guidelines: (1) out-of-market efficiencies and (2) fixed-cost savings. We conclude with some thoughts about the implications of the asymmetric updates for judicial adoption of the 2010 Guidelines.  相似文献

This paper investigates the role of the business press in creating and disseminating information around earnings announcements by examining different motivations of trading volume. We find that press coverage is positively associated with trading activity motivated by differential interpretation and by differential belief revision, consistent with the press playing both an information creation and information dissemination role around earnings announcements. When we divide press coverage into full articles with additional editorial content and news flashes merely repeating verbatim of firm-disclosed press releases, we find that trading volume motivated by both differential interpretation and differential belief revision increases as coverage by full articles increases, and trading volume motivated by differential belief revision increases as coverage by news flashes increases. We also report that the differential interpretation effect of full articles is more pronounced when information users’ sophistication is high. Overall, we provide new evidence to the literature by showing that each type of press coverage plays an informational role in different motivations of trading activity.  相似文献

It is often argued that attribute adjustments made possible within choice experiments have the potential to improve benefit transfer accuracy. These transfers, however, often omit socioeconomic adjustments; this reflects a limited presence of socioeconomic covariates in broader choice experiments. The lack of correspondence between common guidance that socioeconomic adjustments should be applied and simultaneous arguments for the advantages of choice experiment transfers leads to ambiguity for transfer practice. This paper contrasts the change in transfer performance resulting from an ability to adjust for policy attributes with that resulting from an ability to adjust for socioeconomic attributes. Results are illustrated for the case of agricultural land preservation. The goal is to provide evidence regarding the tradeoff faced by practitioners who seek to use choice experiments for benefit transfer but lack the ability to adjust for socioeconomic attributes.  相似文献

Since the onset of the global financial crisis, China and the U.S. have reduced their current-account imbalances as a share of GDP to less than half their pre-crisis levels. For China, the reduction in its current-account surplus post-crisis suggests a structural change. Panel regressions for a sample of almost 100 countries over 1983–2013 confirm that the relationship between current-account balances and economic variables changed in important ways after the financial crisis. China’s rebalancing has been accompanied by a decline in its reserves-to-GDP ratio and greater outward FDI that, in turn, has mitigated reserve hoarding.  相似文献

We argue that inertial behavior on the part of investors can have significant consequences for corporate financial policy. One implication of investor inertia is that it improves the terms for the acquiring firm in a stock-for-stock merger, because acquirer shares are placed in the hands of investors, who, independent of their beliefs, do not resell these shares on the open market. In the presence of a downward-sloping demand curve, this leads to a reduction in price pressure and, hence, to cheaper equity financing. We develop a simple model to illustrate this idea and present supporting empirical evidence.  相似文献

The paper investigates why a developing country may adopt a partial reform. A country is considered where the ruling elite (referred to as state capital) prevents the entry of foreign capital, and taxes the private sector before reform. A higher productivity of foreign capital always increases the attractiveness of a partial reform under which state capital can control the inflow of foreign capital, but can reduce the attractiveness of a full reform under which the entry of foreign capital is unregulated. Hence, state capital's control over foreign capital may be a necessary condition for the reform to take place at all.  相似文献

Justin Kaplan's When the Astors Owned New York is a probingaccount of how and why the two cousins—William WaldorfAstor and John Jacob Astor IV—spent much of their livesdecorating Manhattan's skyline with grand hotels. Kaplan, aPulitzer Prize-winning biographer of Mark Twain, draws on personalpapers, contemporary press accounts, and various literary worksto locate the Astors in Gilded Age New York high society. TheAstors built hotels not simply to make money, Kaplan contends,but also  相似文献
