For years, the Securities and Exchange Commission (SEC) accidentally distributed securities disclosures to some investors before the public. We exploit this setting, which is unique because the delay until public disclosure was exogenous and the private information window was well defined, to study informed trading with a random stopping time. Trading intensity and the pace at which prices incorporate information decrease with the expected delay until public release, but the relation between trading intensity and time elapsed varies with traders' learning process. Noise trading and relative information advantage play similar roles as in standard microstructure theories assuming a fixed time window. 相似文献

In this article, we use count data regression with sample selection to analyze the effects and degree of moral hazard in demand for visits to physicians among groups of individuals with similar body mass index (BMI). Our results suggest that the effect of moral hazard on the demand for visits to doctors is increasing in BMI for men and for overweight and obese women. Moral hazard is highest among overweight men.

Objective:Venous thromboembolism (VTE) (deep vein thrombosis [DVT] and pulmonary embolism [(PE]) represents a substantial economic burden to the healthcare system. Using data from the randomized EINSTEIN DVT and PE trials, this North American sub-group analysis investigated the potential of rivaroxaban to reduce the length of initial hospitalization in patients with acute symptomatic DVT or PE.Methods:A post-hoc analysis of hospitalization and length-of-stay (LOS) data was conducted in the North American sub-set of patients from the randomized, open-label EINSTEIN trial program. Patients received either rivaroxaban (15?mg twice daily for 3 weeks followed by 20?mg once daily; n?=?405) or dose-adjusted subcutaneous enoxaparin overlapping with (guideline-recommended ‘bridging’ therapy) and followed by a vitamin K antagonist (VKA) (international normalized ratio?=?2.0–3.0; n?=?401). The open-label study design allowed for the comparison of LOS between treatment arms under conditions reflecting normal clinical practice. LOS was evaluated using investigator records of dates of admission and discharge. Analyses were carried out in the intention-to-treat population using parametric tests. Costs were applied to the LOS based on weighted mean cost per day for DVT and PE diagnoses obtained from the Healthcare Cost and Utilization Project dataset.Results:Of 382 patients hospitalized, 321 (84%), had acute symptomatic PE; few DVT patients required hospitalization. Similar rates of VTE patients were hospitalized in the rivaroxaban and enoxaparin/VKA treatment groups, 189/405 (47%) and 193/401 (48%), respectively. In hospitalized VTE patients, rivaroxaban treatment produced a 1.6-day mean reduction in LOS (median?=?1 day) compared with enoxaparin/VKA (mean?=?4.5 vs 6.1; median?=?3 vs 4), translating to total costs that were $3419 lower in rivaroxaban-treated patients.Conclusion:In hospitalized North American patients with VTE, treatment with rivaroxaban produced a statistically significant reduction in LOS. When treating DVT and PE patients, clinicians should consider newer anti-coagulants with less complex treatment regimens. 相似文献

The International Accounting Education Guidelines (IAEG) of the International Federation of Accountants (IFAC) issued since 1982 specify the components for the Professional preparation to become a qualified accountant. This paper presents the results of a survey of compliance conducted in fifty-four countries outside the USA with International Accounting Education Guidelines (IAEG), as issued by the International Federation of Accountants (IFAC). Its purpose is to provide a benchmark measure of compliance for current assessment of accounting education, and for reference in future studies. This study is the first attempt to examine compliance with IAEGs in all sectors of the world in which IFAC has members. The paper is divided into the following sections: international accounting education guidelines; survey questions; methodology; results; effectiveness of the guidelines, and summary and conclusions. 相似文献

Over the past decade ‘material culture’ has become a sub‐discipline of Italian Renaissance studies. This literature, however, has focused on the rich and their objects preserved in museums or reflected in paintings. In addition, the period 1300 to 1600 has been treated without attention to changes in the relationship between people and possessions. The article turns to last wills and testaments, which survive in great numbers and sink deep roots through late medieval and Renaissance cities and their hinterlands. They reveal aspirations and anxieties about things from post‐mortem repairs to farm houses to pillows of monk's wool. These aspirations changed fundamentally after the Black Death. Earlier, during the ‘commercial revolution’, ordinary merchants, artisans, and peasants on their deathbeds practised what the mendicants preached: stripping themselves of their possessions, they converted their estates to coin to be scattered among pious and non‐pious beneficiaries. After the Black Death, testators began to reverse tack, devising ever more complex legal strategies to govern the future flow of their goods. This work of the dead had larger economic consequences. By encouraging the liquidation of estates, the earlier mendicant ideology quickened the velocity of exchange, while the early Renaissance attachment to things did the opposite. 相似文献

To paraphrase an old saying: Everybody complains about the way obsolescence is handled in tax depreciation practice, but nobody has as yet found a solution that satisfies both the taxpayer and the tax collector. It is obvious that this problem is much too big to treat in detail in this short article, but an attempt will be made to discuss several aspects of the problem which the writer believes either have not been fully understood by most persons, or else have not been explained sufficiently by those who advocate certain procedures. In order to develop the subject adequately, it will be necessary to investigate certain matters not directly concerned with tax practice 相似文献

‘Land grab’ has become a catch‐all phrase to refer to the current explosion of (trans)national commercial land transactions mainly revolving around the production and export of food, animal feed, biofuels, timber and minerals. Two key dimensions of the current land grab – namely, the politics of changes in land use and property relations change (and the links between them) – are not sufficiently explored in the current literature. We attempt to address this gap by offering a preliminary analysis through an analytical approach that suggests some typologies as a step towards a fuller and better understanding of the politics of global land grabbing. 相似文献

In 1970 the New York Stock Exchange relaxed rules that prohibited the public incorporation of member firms. Investment banking concerns went public in waves, with Goldman Sachs the last of the bulge bracket banks to float. We explain the pattern of investment bank flotations. We argue that partnerships foster the formation of human capital and we use technological advances that undermine the role of human capital to explain the partnership's going‐public decision. We support our theory using a new data set of investment bank partnership statistics. 相似文献
